How to fertilize citrus during planting?

With the progress of science and technology and the development of society, many people now choose mechanical integration when planting crops. But there are many farmers who love labor very much, and they will choose to grow by themselves. It is believed that many farmers will plant a large number of fruit trees in front of and behind their houses, especially in the autumn harvest season, and they will sell them at a good price.

Citrus is believed to be a very popular fruit to eat, and it is also very common. So how do you fertilize citrus during planting? <>

First, choose seedsFirst of all, we choose seeds in the market, and we must pick a relatively full one. The picked seeds can be soaked in warm water for a day, which will also improve the germination rate of the seeds. As we all know, before the seeds germinate, there is a great need for water, so you can also water the citrus seeds regularly.

In addition, farmers can also regularly observe the growth of seeds to prevent pests and diseases. <>

2. Precautions But some people will apply fertilizer in order to make citrus grow faster. However, it is advisable to apply fertilizer in the summer, which will also promote the absorption of citrus roots. We must not fertilize too often, otherwise it will not only not play a positive role, but will play a role.

If the fertilizer concentration is too high, the yield of citrus will be greatly reduced, and the special juice of the citrus will not be so sweet. Therefore, it is recommended that you fertilize once a week, and there is no need to fertilize too many times. <>

3. In autumn, citrus will be more or less attacked by pests and diseases. If you want the most direct and effective method, then it is recommended that you choose chemical control. In simple and straightforward words, it is to spray pesticides directly.

It is a drug that is three parts toxic, so everyone must grasp the dosage of pesticides. But if you want to be green and healthy, you can use biological control.

The cultivation of citrus needs to pay attention to a lot of doorways, and it must be fertilized in strict accordance with the scientific amount of fertilizer in order to grow large and sweet citrus, 1Spring germination fertilizer.

Fertilizer is applied in the spring during the bud break to help the shoots absorb nutrients, so the best time to apply fertilizer is in early April, when the citrus trees are budding. Only the accuracy of fertilization time can play the function of fertilizer to promote the growth of fruit trees in time.

2.Fruit fixing fertilizer in summer.

After mid-May, there are two fruit-falling periods. Fertilization during the fruit drop period can supplement the necessary nutrients, play a role in stabilizing the fruit, and improve the quality and yield of the fruit.

3.Autumn fruit fertilizer.

The end of July to the beginning of September is a critical period for determining the yield and quality of fruits. Therefore, good fertilizer application not only accelerates fruit growth and flower bud differentiation, but also is a key link to improve citrus yield and quality. Apply fertilizer well, provide sufficient nutrients, ensure fruit yield and quality, and have a good harvest in the year.

4.Harvest fruit harvesting fertilizer.

The annual growth and development of citrus trees consumes a huge amount of nutrients, and there are almost no nutrients left. Therefore, after picking the fruit, applying fertilizer to supplement nutrients in time will help the recovery of fruit trees, promote high-quality treetop differentiation, and ensure the yield and quality of fruits in the coming year.

In the process of citrus fertilization, controlling the amount of fertilizer is the key link to ensure the healthy growth of citrus. The age of fruit trees, the amount of fruit, and the quality of soil affect the amount of fertilization. In general, compound fertilizers are used, and according to NPK2:

The ratio of 1:2 fertilizer is allocated, so that the nutrients needed by the fruit trees can be accurately distributed and the fruit trees can be fertilized reasonably. Two kilograms of compound fertilizer per citrus tree can be applied to meet the nutrient requirements during the growth process.

Citrus can be fertilized during the growth of citrus, and when planting citrus, the soil should also be fertilized, and the citrus should be fertilized in the right season, and when the citrus lacks nutrients, it should also be fertilized.

First of all, it is necessary to choose the right fertilizer according to the planting area, about 1500 kg of fertilizer is needed for one acre, and then you can also choose organic fertilizer plus potassium fertilizer and phosphorus fertilizer mixed together, and then do not compost the situation, be sure to water in time.

It is necessary to understand photosynthesis, and at the same time pay attention to the growth of citrus, choose the right fertilizer, and apply fertilizer according to the flowering period and cultivation method.

Fertilizer is the source of nutrients for the normal growth of citrus, and reasonable fertilization can not only ensure the growth of fruit trees and high quality and high yield, but also improve the fertility of the soil and improve the structure of the soil in the orchard. I think that when the newly planted fruit seedlings are growing new shoots, it is also when the root system of the fruit seedlings grows to apply a small amount of water and fertilizer with a small concentration, and then press one tip and two fertilizers or apply thin application on time to ensure the smooth growth of fruit seedlings.

One year later, the fertilization of citrus fruit trees includes three types: basal fertilizer, top dressing and foliar fertilizer. Basal fertilizer (spring fertilizer is applied before germination; Autumn fertilizer is generally around mid-August, and some fruit trees are late July; Winter fertilizer is fruit picking fertilizer) is the main fertilizer throughout the year, so it should be based on organic fertilizer, supplemented by compound fertilizer, and then add a certain amount of micro fertilizer according to the actual situation, and the fertilization time is generally applied before the citrus growing season, of which autumn fertilizer is the most important.

Spring application to promote germination and strong bud fertilizer

Fertilizer should be mainly chemical fertilizer, and the application rate of nitrogen fertilizer should be increased. In early to mid-April, when the flower buds appear, nitrogen fertilizer is applied once depending on the number of flower buds, combined with root top dressing, boron fertilizer, trace elements and auxin.

Summer application of fruit fertilizer

Citrus from the beginning to mid-May after flowering and fruiting, there are two physiological fruit drop peaks, this time should look at the tree fertilization, if the flowers and fruits, fertilization is more, flowers and fruits are less and vegetative branches are more, it should be applied less or not applied. And should be based on root topdressing, with a variety of fertilizers can be mixed with pesticides spray, both fertilization and insect control.

Autumn application of strong fruit topping fertilizer

Autumn shoots are reliable fruiting mothers for the coming year. Fertilization should be applied in late July. This time, phosphorus and potassium fertilizers were mainly used, and nitrogen fertilizers were applied lightly to improve quality and increase yield.

Apply overwintering fertilizer in winter

Winter is the dormant period of citrus and the differentiation of flower buds. Fertilization should be done sooner rather than later, mainly with farmhouse rotting fertilizer, and applied before the end of November. This has a direct impact on tree recovery and nutrient accumulation, as well as on improving the cold tolerance of citrus trees.

Top dressing is a fertilizer applied during the growth of citrus trees in order to supplement the lack of basal fertilizer, and chemical fertilizer should be the main fertilizer at this time, so that the fruit tree can quickly absorb the corresponding fertility; Foliar fertilizer can be classified into top dressing series from the general direction, which is the fastest way to supplement the lack of fertilizer in fruit trees. However, in the process of citrus growth, foliar fertilizer should not be used alone to fertilize fruit trees, and it should be a reasonable combination of basal fertilizer and foliar fertilizer.

Citrus does not need to be fertilized during the flowering period. Fertilization should be done before flowering, after germination, etc.

Fertilizing before flowering helps citrus develop fruit. Fertilizing after germination helps citrus seedlings grow strongly.

Citrus does not need to be fertilized when it blooms, it is necessary to apply fertilizer well before flowering, and fertilization before flowering can promote fruit trees to produce more flower buds, so that there will be more flowers and more fruits.

It is definitely needed, and at this time it is necessary to use well-rotted organic fertilizer. It is better to fertilize in the spring shoot germination stage, which can promote plant growth and increase yield.

According to professional data surveys, when planting citrus, the proportion of nitrogen and potassium fertilizers is the highest for every 1000kg of fruit produced, followed by phosphate fertilizers, and finally nutrients such as calcium and magnesium. The proportion of nitrogen, phosphorus and potassium should be controlled as early as possible. The nutrient demand of citrus tends to grow in spring, which reduces the fruit setting rate; For example, the excess nitrogen in the later stage and the continuous occurrence of late autumn shoots will affect the overwintering of citrus. If there is a nitrogen deficiency in the citrus fruit expansion stage, the physiological fruit drop is serious, the fruit is small, and the yield is low.

However, excessive potassium application will also increase the thickness of the peel and affect the quality.

Citrus fruit-strengthening fertilizer is applied about 7 to 9 months after the fruit drop has stopped, and can be applied once or in two parts. Fruit-preserving and fruit-strengthening fertilizers should be paid equal attention to nitrogen, phosphorus and potassium, especially the proportion of potassium should be increased in fruit-strengthening fertilizers to promote rapid fruit expansion, autumn shoot extraction and flower bud physiology and biochemistry. Citrus fruiting early, long fruiting period and large flowering; In a year, it is generally in spring, summer and autumn to draw shoots 3 times, if the winter temperature is warm, you can also draw winter shoots, the roots are particularly developed, there is no obvious deep dormancy time throughout the year, so the perennial normal hanging fruit tree nutrients are consumed.

The sufficient nutrient supply here not only includes the nitrogen, phosphorus and potassium fertilizers we commonly use, but also includes fermented and well-decomposed organic fertilizers, which can adjust the structure and activity of the soil and improve the utilization rate of chemical fertilizers. In addition, citrus consumes a lot of nutrients for calcium, magnesium, boron, and zinc citrus trees to flower, and it is necessary to apply enough fertilizer to ensure the nutrients needed for citrus trees to flower. At this time, fertilization, mainly compound fertilizer, you can add a little nitrogen fertilizer, and the amount of fertilizer per acre is about 12 kg. Do not apply too much fertilizer to prevent root burning.

Using the integrated management method of water and fertilizer, dilute and dissolve various elements required by fruit trees, scoop out inferior fillers, improve the utilization rate and concentration to and purity, mix and match poultry feathers to ferment and rot into a slurry, match the appropriate amount of water, apply thin fertilizer frequently, and manage a small amount of phosphorus and potassium and other rich nutrients. It can not only provide comprehensive nutrition for crops, but also has long fertilizer effect, can increase and renew soil organic matter, promote microbial reproduction, improve the physical and chemical properties and biological activity of soil, and is the main nutrient for green food production.

You can choose foliar fertilization or root fertilization, and the things used are the same, but the part of the fertilization is different.

The fertilizer should be buried inside the roots so that the citrus can absorb nutrients from the roots.

When planting citrus, it is necessary to apply fertilizer first, and then fertilizer is applied in turn according to the growth cycle of citrus, and it is important to pay attention to its water amount and soil environment.

These characteristics should be taken into account when fertilizing, if the fertilizer is not applied reasonably, it will bring harm. When spring shoots bud out, there is a surplus of nitrogen, and spring shoots are easy to grow, reducing the fruit setting rate; In the later period, there was a surplus of nitrogen, and late autumn shoots continued to appear, which affected the overwintering of citrus. If the fruit is deficient in nitrogen during the swelling period, citrus fertilization is simply said to be twice, the first time is to reapply basal fertilizer after the fruit is set, mainly organic fertilizer. Cattle, pigs, and chickens are the best.

Properly buy some organic granular fertilizer of Laiteng Industrial Company, and apply it immediately after flowering and fruiting, and the effect is very good.

<> is fertilized after fruit picking from December to January of the following year, which is needed for the spring shoot period, and the late-acting fertilizer is the main one. In February, the vigorous trees before the spring shoots are not applied, and the weak trees are applied with a quick effect of water and fertilizer to promote the growth of spring shoots. In May and June, no fertilizer is generally applied to control the growth of summer shoots.

Re-application before autumn, mainly fast-acting water and fertilizer, 3 4-year-old early fruiting trees to pre-autumn, winter re-application, spring fertilizer to see flowers, summer before the principle of no application. That is, from December to January of the following year, fertilizer is applied after fruit picking to store the nutrients required for the spring shoot period, and late-acting fertilizer is the main one. In February, the spring fertilizer before the spring shoots is like a good tree, and it is the first fruiting tree, citrus generally needs more fertilizer in three periods, the first period, after harvesting the fruit, you can apply fruit fertilizer, which is the so-called winter and spring fertilizer; The second period is after the end of the second physiological fruit drop, the so-called stable fruit fertilizer can promote the expansion and quality of young fruits.

Mid to late June is the fruit expansion period, and the amount of fertilizer accounts for about 60% of the annual fertilizer amount. The method is to open a ditch outside the drip line of the canopy and apply it, the ditch is 15 20 cm deep, the ditch is 25 35 cm wide, generally according to the 100 catties of fruit to apply organic fertilizer (rotted cake fertilizer) kg citrus is a relatively large amount of fertilizer required fruit, it can be said that the fertilization of citrus is directly related to the growth of the tree and the yield of autumn, so from the base fertilizer to the top dressing of each period, it must be done in place, otherwise there may be a reduction in yield, size and other situations.

China is one of the important origins of citrus, with abundant citrus resources and a wide variety of excellent varieties. Citrus trees have long life, high yield and high economic benefits, and are the most important tree species of fruit trees in southern China.

At the beginning of planting, this time should be some basal fertilizer, which is very helpful for its growth. Then apply some household fertilizer or phosphate fertilizer to it when it grows seedlings or during its growth period, so that its roots can be supplemented with more nutrients.

Try to choose to fertilize at night, because then the plant can have a better absorption, and it will have a certain good effect on the plant itself, and the amount of fertilizer should be less, and at the same time, you should also water some water after fertilization.

Spring fertilizer, relative to citrus fruit trees in the spring fertilizer the best period is between March and April, but where the beginning of fertilizer must be on time and according to the amount of fertilizer, the way of fertilizer is mostly the use of manual spraying, this kind of way is one of the most common ways for everyone, manual spraying can also grasp the condition of each fruit tree.

The application of fruit fertilizer from July to September is one of the key technologies for stable and high yield of citrus, and it is also an effective measure to prevent the annual fruiting phenomenon of citrus size. Grasp the fertilization period from July to September, which is the period of citrus fruit expansion. Plants need a lot of fertilizer, so we should apply strong fruit fertilizer in time.

For adult trees in the whole fruiting stage, strong fruit fertilizer should be applied in mid-July; Young trees in the early fruiting stage should be planted from late July to early August, which is conducive to fruiting and early autumn shoots. Citrus trees with weak trees and hillside citrus orchards should be applied early, and citrus orchards with sufficient water should be applied late. Heavy application of strong fruit fertilizer needs to be nutritious and complete during the strong fruit period. Therefore, phosphorus, potassium and organic fertilizers should be combined with the rational application of available nitrogen fertilizers.

The amount of fertilizer should account for about 30% of the total amount of fertilizer applied throughout the year, and early and super early maturing varieties such as Miyamoto Hoshijin and Oita should be applied in early July, while late maturing varieties, such as Zhang Wei, in general, it is best to choose compound fertilizers containing nitrogen, phosphorus and potassium. Fertilizer rate: apply kilogram of ** fruit compound fertilizer per plant.

When applying strong fruit fertilizer, attention should also be paid to the application of potassium fertilizer. Reasonable application of foliar fertilizer in the fruit-strengthening period from July to August, and the spraying of foliar fertilizer outside the root also had a significant effect on fruit strengthening and improved fruit quality. Urea, potassium dihydrogen phosphate solution or other multi-compound fertilizer solution can be sprayed once every 10 15 days, and the effect of spraying twice is better; Cloudy or sunny days are recommended at 10 a.m

Foliar fertilizer is sprayed before 00 or after 4:00 p.m. Because there are many pores on the back of the leaf, the absorption capacity is stronger than that on the leaf.

Spray both the leaves and the back of the leaves, and it is advisable not to drip water.

Your situation is typical of fertilization, and there may be two reasons for your current condition: overuse of nitrogen fertilizer. The fertilization season is late. Rational fertilization of nitrogen, phosphorus and potassium has not been paid attention to.

Fertilize two or three times a year, and the amount of re-drying is not much different from the previous one. Fertilization must be carried out in a furrow, buried deeply. If it's too close to the roots, it's bound to burn to the roots.

In addition, sulfur-containing fertilizers must be used for fertilization.

If chlorine-based fertilizer is used, not only is it not sweet, but also different in size, each tree should be topdressed about 50 grams before and after flowering, which can be determined according to the situation at that time. The best thing to do is to see if the leaves are yellow. If the leaves are green, don't paint them.

Why do you need to fertilize in several doses? This is the same as if you need to eat before going to work every day and eat again after the day. If you want to harvest citrus, you can't fertilize it, and you can't eat it only once a few days, at least twice.
