How to fertilize apple trees in April

Pre-flowering fertilizer or germination fertilizer (early April) This period is the critical period of nitrogen nutrition, and it should be mainly based on fast-acting fertilizers such as Dimijia compound fertilizer, and the best effect is combined with Mumei soil.

It depends on what kind of fertilizer, manure and weeds can be dug or added with the right amount of chemical fertilizer. But the fertilizer can be applied when it is watered.

After the early varieties are picked, and before the late varieties are picked, it is the best time for apple trees to apply basal fertilizer in autumn. Advocate an "early", because the autumn shoots basically stop growing, the root system enters the peak of growth, the wounded roots are quick and easy to heal, and can give birth to different numbers of absorbing roots, generally winter fertilizer should be applied at the end of September of the lunar calendar, because this period is the fruit tree confinement fertilizer, that is, the third expansion period of the fruit tree fertilizer has been used up, just like a pregnant woman gave birth to a child, it is necessary to supplement nutrition is a reason, but also for the next year flower buds to expand and bloom an important part.

Fruit trees sprout and bloom in spring, which consumes a lot of nutrients. At this time, if the nutrients are not high, it will lead to problems such as prolonged flowering period and reduced fruit setting rate. According to the growth characteristics of different fruit trees, fast-acting fertilizers should be applied in a timely and appropriate amount.

Under normal circumstances, the fruit trees are fertilized twice a year, the first time is after the apple tree is planted in autumn, that is, in the late autumn and early winter, the fruit trees that have worked hard for a whole year are ready for winter recuperation, and at this time the apple trees should be fertilized to ensure that the fruit trees are replenished with nutrients during the recuperation period.

The first fertilization is from the end of the apple picking, and the apple is picked in October. Of course, the scientific requirement is to apply fertilizer in September and basal fertilizer in autumn. But at that time, the common people were very busy, busy unpacking bags, busy turning fruits, busy picking apples, and busy selling apples.

The law of apple fertilization should be reasonably arranged according to the peak of root development, in spring in April, organic calcium supplementation after flowering, high phosphorus to promote flowering, high nitrogen and high potassium in July to promote expansion, organic calcium supplementation in August to prevent bitter acne and water cracks, and organic high potassium fertilizer to promote expansion and coloring in September.

In spring, more nitrogen fertilizer is needed, and some nitrogen fertilizers (such as urea) will be applied alone in spring, which is very undesirable. At this time, it should be topdressed with phosphorus and potassium fertilizer to make the nutrition of the fruit tree more balanced. Apply sufficient basal fertilizer:

Generally, it is carried out in September and October after the autumn fruit harvest, and the fertilization should be done sooner rather than later, and not later than the end of March of the following year when the fruit trees begin to grow newly. The basal fertilizer should be mainly organic fertilizer, and 40 of the total annual nitrogen fertilizer and 90 of the total annual phosphate fertilizer should be applied

I think fertilization is best in May, because if you fertilize at this stage, the society will make the apples grow very well, and there will be no pests and diseases, so there are many people who will fertilize at this stage.

The time of fertilization should be determined according to the growth situation. In the early stage of growth, fertilization should be applied once in early April and once in mid-May, which can promote the growth of new shoots, flowering, and increase fruit set. If it is in the middle and late stages of growth, it should be applied at the end of May or early June to make the fruit more enlarged, and the fertilizer is mainly potassium fertilizer.

Fertilize the apple tree according to its growth cycle, then apply fertilizer again when it bears fruit, and then fertilize the apple tree after it bears fruit.

When the apple tree is just planted, and the young branches have just been drawn, the flowering period and the fruiting period should be supplemented in time. In addition, after pruning the branches and leaves in winter, fertilizer should also be applied to ensure the healthy growth of the apple tree.

Hello, I am happy to answer for you, apple trees can be fertilized with phosphorus fertilizer in April, usually, spring fertilization of apple trees is from early March to mid-April, which should be carried out before apple budding to before flowering, sooner rather than later. The amount of spring fertilization of apple trees: 1. If there was no autumn basal fertilizer last year, it is recommended to apply organic fertilizer, microbial fertilizer and nitrogen, phosphorus, potassium compound fertilizer and medium and trace element fertilizer with good effect.

Under normal circumstances, apple trees in the peak fruiting period can be applied 10-15 kg of organic fertilizer and micro-grown orange fungus fertilizer per plant, 3-5 kg of nitrogen, phosphorus and potassium compound fertilizer with a ratio of 2:1:2, and medium and trace element fertilizer.

2. If autumn basal fertilizer was applied last year, it is recommended that fast-acting nitrogen fertilizer can be applied last year. Note that the low temperature in spring is low, and urea is not recommended for nitrogen fertilizer, and nitrogen banquet pure fertilizer with nitrate nitrogen as the active ingredient can be used.

Hello! Newly planted apple trees usually start fertilizing within 4-6 weeks of planting. By this time, the root system has adapted to the new environment and has begun to sprout and grow.

Fertilization can help apple trees grow and develop better, improving yield and quality. When fertilizing, it is first necessary to understand the nutrient condition of the soil in order to choose the right fertilizer. Fertilizers that are usually suitable for newly planted apple trees include compound fertilizers or biofertilizers containing nitrogen, phosphorus, potassium and other nutrients.

The following points need to be paid attention to when fertilizing:1Do not over-fertilize, as over-fertilization can lead to root damage or overnutrition, which can affect growth and development.

2.Before fertilizing, remove the surrounding weeds and keep the soil moist so that the nutrients can be better absorbed. 3.

Fertilizer can be sprinkled on the root zone around the apple tree, followed by rotary tillage and deep ploughing to ensure that the fertilizer is evenly distributed in the root zone. 4.According to the fertilizer application needs in different seasons, the type and amount of fertilizer should be adjusted in time.

In conclusion, proper fertilization can help apple trees grow, blossom and bear fruit in a healthy way. Hope it helps.

Hello dear, happy to answer for you. The best time to fertilize apple trees in autumn is from late September to early October. Usually late-acting organic fertilizers, such as humic acids, compost, manure, circle fertilizer, manure, compound fertilizer, crop straw, weeds, etc.

It is supplemented by chemical fertilizer and medium and micro fertilizer, with biological fertilizer, so that the fertilizer can complement each other. Pay attention to the proportion of nitrogen, phosphorus, potassium and other elements in the chemical fertilizer to be coordinated, generally should not be too much nitrogen fertilizer, to prevent the branches of the tree from growing, causing winter shoots, is not conducive to the accumulation of nutrients stored in fruit trees and the improvement of flower bud quality. Based on the fertilization experience in various places, the application rate of organic fertilizer in apple orchards with a yield of more than 1,000 kg per mu should generally reach the standard of "1 kg of fruit and 1 kg of fertilizer".

For a high-yield garden with a yield of 2000-3000 kg per mu, the application rate of organic fertilizer should reach the level of "1 kg of fruit fertilizer". Hope mine is helpful to you! Don't forget to give it a thumbs up!

Summary. In mid to late July, the topdressing of fruit expansion fertilizer is conducive to promoting the growth of new roots, improving leaf function, increasing single fruit weight, increasing grade fruit rate and yield, enriching flower buds and tree nutrient accumulation, improving tree resistance, and laying a good foundation for the high yield and quality of the current year and the bumper harvest of the next year. Generally, about 50 kg of fast-acting compound fertilizer (high nitrogen and high potassium compound fertilizer) is applied per mu, which is conducive to promoting fruit expansion, and topdressing phosphorus and potassium fertilizer can improve fruit hardness and sugar content, and promote fruit coloring.

How much fertilizer is fed to the 9-year-old Pingguo tree, and is it okay to feed it now.

Now that I'm feeding, are you still feeding it before Pingguo.

You can feed now, if you have planted in a field for 9 years, first of all, you should use humic acid water-soluble fertilizer to improve slight soil compaction, improve the absorption capacity of the root system to nutrients, and secondly, for this kind of initial fruiting tree, you can make a balanced water-soluble fertilizer to promote the development of new fruits before the apple tip, and you can make 1-2 kg of apple fertilizer per tree before flowering, to promote flower bud differentiation and fruit set, and you can apply 2-3 kg of apple fertilizer during the fruit expansion and coloring period, and it is a number of fees to spray the fruit swelling. It can effectively promote fruit expansion, good coloring, increase sugar content, increase yield and improve quality.
