I want to ask if when topdressing fruit trees, is it better to water or fertilize first?

As long as the soil can be kept moist and the amount of fertilizer is controlled, the fertilizer effect is actually about the same! It's useless to apply too much, and it's easy to cause fertilizer!

However, if you fertilize first, it is easier to operate, the soil is easier to dig, it will not stick to the hoe, it will not stick to the shoes, after fertilizing, turn the soil over, and water it thoroughly!

Fertilization should be applied diligently, too much at a time, the plant can not absorb, the fertilizer effect of chemical fertilizer is 7 to 14 days, after this time, it will be fixed in the soil, and the soil is easy to compact!

I want to ask if when topdressing fruit trees, is it better to water or fertilize first?

Hello! Water first and then fertilize. This works better.

The fertilization sequence of fruit trees is to fertilize first and then water, which is conducive to the full absorption of fertilizer. It should be noted that different topdressing, the use of different methods is different, most of them need to open a small ditch or dig a potential pit, bury the fertilizer and then water, but water-soluble fertilizer, flush fertilization, you can water while fertilizing.

Top dressing: fertilization in the long period of fertilization and fertilization in the period of expansion, first fertilization and then watering, the pursuit of fertilizer effect of the quick effect.

Bottom fertilizer: watering first, then fertilizing, reducing the loss of fertilizer, so that it slowly dissolves and absorbs, generally after the fruit picking in autumn, or spring base fertilizer.

Trenching: According to the characteristics of the root system of fruit trees, the old roots also have radial grooves with vigorous rooting hairs; The old root hair is easy to degenerate, such as orange trees, and it is advisable to use ring grooves (about the drip line); deep-rooted should be a cave Shi; Shallow-rooted planing and loosening ditch application.

In general, fertilization is combined with watering. In other words, dig a fertilizer ditch along the drip line of the canopy (where the canopy width goes vertically), sprinkle the fertilizer needed by the fruit trees, and then water the fruit trees to help the fertilizer dissolve and facilitate the absorption of the fruit trees. Some water-soluble fertilizers need to be melted directly into a solution before being applied to the orchard.

However, if you still need to water when fertilizing after watering first, it will increase the workload, so it is recommended to carry out fertilization and watering at the same time.

First top dressing, then watering, chemical fertilizer dissolves better, and fruit trees absorb fertility better.

It is more scientific to apply fertilizer to the fruit trees and then water them. The amount of watering is medium,

Hello, you can water.

Fruit trees should be kept dry before fertilization, so that watering after fertilization is more conducive to fertilizer absorption.

In the process of maintenance, the principle of fertilizing first and then watering should be adhered to, so it can be watered after fertilization.

Fertilization and watering time.

Before fertilizing, it is best to keep the soil slightly dry, so that the fruit trees are slightly dehydrated. Watering after fertilization is more conducive to the absorption of fertilizer efficiency; It can be watered immediately after fertilization, or after the next day.

Re-water. When watering, we should pay attention to controlling the amount of water, if the amount of fertilizer is small, you can not add a large amount of water, so as not to dilute the fertilizer and affect the fertilizer efficiency.

In order to ensure the fertilizer efficiency when fertilizing, we can choose to apply water-soluble fertilizer in Haihai and Weihai in the evening of the previous day, and then water it again in the morning of the next day, which is not only conducive to the absorption of fertilizer efficiency, but also dilutes the excess fertilizer effect in the soil, so as to avoid root burning.

Fruit trees must be watered after fertilization. Otherwise, it is not good for the fruit tree.

1. Newly planted fruit trees should not be fertilized. The root system of the newly transplanted fruit tree has not yet grown and matured, and it is easy to burn the roots with fertilizer.

2. When fertilizing fruit trees, it should be applied around the fruit trees, and the scope of fertilization can be determined according to the shadow cast by the crown of the fruit tree on the ground, and under the shadow of the fruit tree, draw a circle along the shadow of the fruit tree, and be careful not to touch the roots of the fruit trees, otherwise it will burn to the roots of the fruit trees.

3. Fertilizer should be applied once before the fruit tree blooms to ensure that the flowers are kept, fertilizer should be applied once after the flowers fall to ensure the fruit rate, fertilizer should be applied once during the growth of the fruit to ensure that the fruit tree bears fruit, and fertilizer should be applied once in the later stage to ensure the growth of the fruit and become larger.

Perennial plants grow in pots, older, roots grow cross-grown in pots, crowded with each other, intertwined roots, affect the growth of new roots, and the ability to absorb nutrients is significantly weakened.

It is good to plant it in the ground, and it is good to plant it, apple trees.

The growth is inseparable from three things: sunlight, air, and water. When turning the pot, change the soil with new soil, apply base fertilizer, and water again, and the apple tree will grow immediately.

However, when watering, it is best to water the rainwater received when it rains, or change the pot The operation of changing the potted plant to another pot is called repotting. There are two situations in potted plants that need to be repotted: one is that as the seedlings grow, the growth of the root group in the pot is restricted.

Part of the root system is pierced from the pot hole.

out, or exposed to the soil surface, at this time the plant should be promptly small.

More than <> years of apple tree potted plants have adapted to the soil inside the pot, and it is no problem if the apple tree is not injured and does not change the original soil composition. On the contrary, turning the pot also plays a role in loosening the soil in disguise.

Second, apple trees belong to the wood family and are not as delicate as flowers. Watering immediately is because turning over the potting will cause damage to the roots, weaken the ability to absorb water, and the potting soil is not too wet. Too much watering will cause the root wounds to rot, and when new roots grow, you can increase the amount of watering.

After turning the pot, the potting soil should not be dry, otherwise the roots of the potted plant will wither, first of all, the apple is a fruit tree that needs more water, except for the week before the fruit is picked and the dormant period can not be watered, the other phenological periods need different amounts of water. Potted apple trees are usually watered a few days before repotting, so the moisture of the soil is very low under normal conditions, and the operation of changing to another pot at this time is called repotting. There are two situations in a potted plant that need to be repotted:

One is that as the seedlings grow, the growth of the root group in the pot is restricted. A part of the root system from the pot hole, or exposed to the soil surface, at this time should be timely the plant has a small pot to a large pot, expanding.

Yes, not watering will burn the fruit tree to death, the so-called burning, generally after fertilization, watering can dilute the fertilizer, in addition to the fertilizer and water chemical reaction, the fruit tree is more likely to absorb the substance.

As long as it is not over-applied fertilizer, there is no great harm to the fruit tree itself, except for the waste caused by the high fertilizer loss rate. Watering fruit trees after fertilization has the advantage of a high conversion rate of fertilizer use and is not limited by natural weather conditions.

Fertilization is not watered, the trunk of the fruit tree opens its mouth", the fruit tree is fertilized, there is no water cooperation, the fruit tree can not absorb it, that is just put the fertilizer in the soil, let the fruit tree look at it, just like a person is particularly hungry, put a bunch of delicacies in front of you, but can not eat, is it very uncomfortable? However, there are times when the fruit tree does not need to be watered after fertilization or needs to be watered after a few days.

This proves that the best time to apply basal fertilizer in autumn is from August 20 to September 10, which just verifies the two nutritional stages in the growth habit of Red Fuji: spring shoots use the nutrients stored in the previous year, and stop growing from late May to early June, which is the first nutritional stage; From late June to the year of defoliation, it is said that it depends on what fruit trees, generally speaking, the use of base fertilizer is carried out after harvesting, and the high-nitrogen compound fertilizer or calcium supplement is applied before germination, and the balanced or high-phosphorus type is used in the young fruit stage, and the high-potassium type is used in the expansion period and coloring stage.

Of course, as a human being, we have the ability to take the initiative and know that we need to eat when we are hungry, and sometimes we will eat because we are not hungry. Moreover, because of the individual's differences, some people eat three meals a day, some people eat more than one meal a day, some people even skip grains. Depending on what kind of tree you plant, each type of tree, the amount of fertilizer and element required in each period are different, but overall, apply high nitrogen fertilizer in early spring to promote crop growth, quickly improve leaf color, apply high potassium fertilizer at the flowering and fruiting stage, improve fruit setting rate and accelerate fruit expansion, apply high phosphorus fertilizer after fruit picking, as the saying goes

The time is before or after flowering after clearing the garden, mainly nitrogen fertilizer, because the liquid nitrogen consumption is serious after the tree flowering, and if nitrogen is not replenished in time, it will fall flowers and fruits, (apple trees are thinning flowers in the bud stage to save energy.) There are irrigation conditions can be fertilized with water, unconditionally can be applied after root injection or rain, fertilization is a very technical agricultural yield increase measure, some farmers often spend money to buy a lot of fertilizer, but the effect of application is not ideal. This is because of the lack of understanding of fertilization, fertilization should pay attention to the type of fertilizer used, the amount of fertilizer, the nutrient distribution ratio, the fertilization period, the fertilization method and the fertilization of the tree is divided into two kinds, the bottom fertilizer is also called the base fertilizer to soil miscellaneous fertilizer or fermented pigs, cattle, sheep and other manure, to freeze before the ditch or hole application.

It is not suitable for use after the year. The second is chemical fertilizer, no matter what kind of application it is, it must be watered immediately to increase the effect. If the tree is late, potassium sulfate should be applied several times.

Fertilize in the spring at a young age. In the process of planting fruit trees, spring is an important period for their budding, leaf development, and flowering. This period includes the energy of all life activities of the fruit tree and the growth of all parts, and it is very necessary to provide a large amount of nutrients, which is related to whether the fruit tree can grow and develop healthily in the later stage.

So in the spring, it is the first important period for the fruit trees to be fertilized. 2. Fertilization at the beginning of the fruit period in summer. Summer is an important period to promote the differentiation of fruit trees and improve the yield and appearance quality of fruit trees, so it is also very necessary to top dressing in summer.

According to a large number of practices, it has been proved that when topdressing in summer, the fertilizer time with high potassium, low nitrogen and low phosphorus is the most appropriate. And the earlier the topdressing time, the better, which is most beneficial to the growth of fruit trees. 3. Fertilization in autumn during the peak fruit period.

Autumn is an important period for fruit trees to store nutrients, and fertilization has a very important transitional effect on fruit trees at this time. Because if the fruit tree bears too much fruit or has too many insect pests during the growing season, it may cause overnutrition; If the nutrients stored in the tree are not enough to continue budding, flowering and leafing in the following year, the overall yield and quality of the fruit tree will be affected.

Generally, it is better to fertilize in the evening, because the soil temperature is relatively high, and after fertilization, the fertilizer will quickly melt into the soil and be absorbed.

1.To fertilize fruit trees, we must first know that the absorption of fertilizer by fruit trees is mainly done through root hairs. Therefore, spraying a new type of high-lipid membrane compound fertilizer in the concentrated distribution area of root hairs can improve fertilizer utilization efficiency, promote early growth and rapid growth of fruit trees, and increase yield and income.

2.Fertilization of fruit trees should be concentrated at the edge of the crown projection or slightly farther away, not too close to the trunk, because there are thick roots near the trunk, and there are few fine roots and root hairs, which is not conducive to the absorption of fertilizer.

3.To fertilize fruit trees, deeply grasp the following principles: fruit trees with deep root distribution should be applied deeply, and vice versa; Organic fertilizer decomposition is slow, but the fertilizer period is long, can be applied deeply, chemical fertilizer fluidity is large, can be shallow, such as pear trees and other deep-rooted fruit trees should be applied organic fertilizer at a depth of 40-60 cm, plum trees and other shallow root fruit trees should be applied at a depth of 30-40 cm.

After fertilization, a new type of high-lipid film was sprayed to improve fertilizer efficiency.

At the time of planting, apply some fertilizer at the bottom of the pit as basal fertilizer, if no basal fertilizer is applied. The base fertilizer is best organic fertilizer, because the content of various elements of organic fertilizer is relatively low and safer, on the other hand, the fertilizer effect of organic fertilizer is relatively long, which is conducive to the slow absorption of fruit trees. Or spray foliar fertilizer with new high-fat film, and spray strong fruit tilling once before flowering, young fruit stage, and fruit expansion stage to thicken the fruit pedicle and improve the amount of nutrient delivery.

Prevent falling flowers, falling fruits, cracked fruits, stiff fruits, and deformed fruits, so that the fruits are beautifully colored, beautiful in shape, and in good taste.

<> especially chemical fertilizers, because it generally takes 10-30 days for planted trees to take root, and it takes a period of time for new roots to grow to strong roots. Grow new roots, at this time there is no need to apply any fertilizer, just ensure that they are not sunburned. When the tree is stronger, then start to apply thin fertilizer, and the fertilizer for small seedlings within 3 years is also very simple, basically phosphorus powder and ammonium nitrogen, with some farm fertilizer or organic fertilizer.

Avoid the application of raw fertilizer to cause fertilizer damage, produce root burning, and affect the growth and development of the root system. Secondly, the amount of organic fertilizer can be applied according to the fruiting situation of the fruit tree, and 1500 kg of organic fertilizer can be applied per mu during the fruiting period of the fruit tree. In the later stage, it will lead to excessive growth of the tree, affecting flower bud differentiation and fruit development.

It is recommended to apply basal fertilizer as little as possible, spray foliar fertilizer and new high-fat film more, and at the same time, it can be combined with spring irrigation, top application of chemical fertilizer, mainly nitrogen and phosphorus fertilizer, with an appropriate amount of potassium fertilizer.

The formation of carbohydrates is closely related, if the chlorophyll content in the fruit tree is reduced, the leaf color will change to light green or yellow-green, photosynthesis will be weakened, the carbohydrate content will also be reduced, and for the fruiting tree, the taste and flavor of the fruit will also be reduced. Urea has high nitrogen content, strong water solubility, quick effect, and stable chemical properties, and is one of the more commonly used chemical fertilizers for fruit growers. Urea is used as top dressing, which can promote the growth of fruit trees and improve the photosynthetic function of leaves during the critical period of growth and development.
