How do you top dress peach trees? How to fertilize peach trees

1. Top dressing before germination:After the soil thaws in spring, peach trees are applied 1 to 2 weeks before germination to promote the growth of roots and new shoots, ensure good fertilization of flowering, and improve the fruit setting rate.

2. Top dressing after flowering:In order to promote the growth of new shoots and fruits, and reduce fruit drop, fast-acting nitrogen fertilizer can be applied again 1 2 weeks after flowering.

3. Top dressing in the hard-core period:The time is generally in early to mid-June. At this time, top dressing can promote embryo and nuclear development, flower bud differentiation and fruit expansion, and can also lay the foundation for the next year's fruit.

4. Top dressing during fruit expansion period:For medium and late maturing varieties, nitrogen fertilizer should be used as the main fertilizer, combined with potassium fertilizer application, to improve fruit yield and quality.

5. Post-harvest top dressing:After the fruit is harvested, it is necessary to apply phosphorus and potassium as the main fertilizer, combined with nitrogen fertilizer to supplement the tree consumption fertilizer, strengthen the nutrient accumulation of the tree, and improve the wintering ability, so as to ensure the continuous high yield of the orchard in the coming year.

Top dressing is a variety of fast-acting chemical fertilizers applied in the soil during the annual growth period to supplement the urgent need for fertilizer for fruit trees. Such as: urea, ammonium bicarbonate, diammonium phosphate and various fast-acting compound fertilizers (such as Sakefu, etc.).

Most of these fertilizers are characterized by strong water solubility, fast root absorption, short persistence, and relatively single nutrients.

1) Top dressing period.

According to the characteristics of peach tree shoots, fruit growth and fertilizer absorption in the annual cycle, top dressing can be carried out in the following key periods:

Top dressing in the budding stage:

Early spring is the period of regeneration of tree body tips, leaves, flowers, fruits and other organs, which require a large amount of nutrients, such as nutrients stored in the tree and various mineral elements and water absorbed by the underground root system. Under the condition of sufficient nutrition, the tree germinates neatly, grows fast, grows new organs strongly, has a high fruit setting rate, and develops young fruits quickly. At this stage, nitrogen fertilizer is the main fertilizer, and urea can be applied.

Top dressing in the hardcore period:

The hard core stage is the stage of development of the seed embryo, and after passing through this stage, the fruit enters the second rapid growth stage. At this stage, fertilization should be combined with nitrogen and potassium fertilizer, the amount of nitrogen fertilizer should be less, and the amount of potassium fertilizer should be more. This is a key top dressing, for the middle and late maturing varieties should be carried out 1 2 times of top dressing according to the growth of the tree after the top dressing, and nitrogen and potassium fertilizer should be applied together.

Postharvest fertilization: Mainly for medium and late maturing varieties with more nutrient consumption and trees with weak tree potential, postharvest fertilization can restore tree potential, improve the photosynthetic capacity of leaves, and promote the autumn return of nutrients in the tree.

Due to the different soil and climatic conditions, the growth and fruiting conditions of trees are also different in different places. Therefore, the time and frequency of topdressing should be flexibly controlled according to the development of the tree, the characteristics of the variety and the soil conditions. Generally, top dressing can be carried out 3 to 4 times a year. Irrigation should be done in time after each fertilization.

2) Top dressing application method.

Shallow trench method: according to the size of the canopy, the amount of top dressing, and the type of fertilizer, the shape, depth, quantity and length of the trench are determined. The shape of the top dressing ditch includes semi-annular ditch, annular ditch, straight ditch, radial ditch, etc.; The depth is mostly about 10 cm.

Sprinkle the top dressing evenly into the furrow. When the amount of fertilizer is large, it should be mixed with the soil, and the fertilizer block should be broken, otherwise it is easy to cause fertilizer damage, and then cover the soil, rake it flat, and water it.

Hole application: According to the size of the canopy, dig 6 12 square holes or round holes with a depth of 10 cm under the canopy, and apply fertilizer to the hole to rake flat and water.

Annular ditch method: that is, a shallow ditch (10 cm deep) around the crown is opened around the canopy, fertilizer is applied into the ditch, the soil is filled and leveled, and watered. The location of the annular furrow is generally on the outer edge of the canopy.

Radial ditch method: dig 4 6 shallow ditches 10 cm deep evenly from the trunk 50 60 cm to the periphery of the canopy, apply fertilizer into the ditch, fill the soil and cover it, and water it.

Hello! On the basis of basal fertilizer application for peach trees, the key periods of top dressing are the hard core stage and the fruit expansion stage. In the early stage, high-nitrogen compound fertilizer was applied to promote the growth of new shoots and young fruits, and high-potassium compound fertilizer was applied in the later stage to promote fruit expansion.

In spring, the peach leaves and buds have already sprouted. From germination to flowering to the growth of new leaves, last year's trunk stored a large amount of nutrients that were needed by the grandchildren. Therefore, in order to avoid consuming too much nutrients and affecting the vitality of trees, it is necessary to be fully prepared for spring fertilization.

So how does it work? Let's learn the essentials of spring peach tree fertilization techniques.

Critical period of fertilization.

1. Pre-bud fertilizer.

After the temperature rises in early spring, the nutrient demand of peach trees gradually increases, and attention should be paid to the application of pre-bud fertilizer. It is generally used 15 days before the beginning of spring. Nitrogen, potassium and phosphorus were applied to each peach tree. It is best mixed with mature human and animal manure.

2. Pre-flowering fertilizer.

Nitrogen fertilizer should be the main fertilizer before flowering, and 6-8 kg or 12-20 kg of urea per mu can be applied according to the actual growth of peach trees. Peach tree fertilization before flowering and irrigation before flowering work best.

3. Fruit setting fertilizer.

Fruit setting fertilizer for peach trees is generally suitable for application from post-flowering to pre-hardcore, and early-maturing peach varieties should be applied as early as one month after flowering. According to the growth potential of the tree, the urea dosage can be 5-10kg mu or 10-20kg mu.

4. Fruit-promoting fertilizer.

When the young fruit of peach tree enters the hard core stage and the young fruit begins to expand rapidly, the fruit-promoting fertilizer should be re-applied to promote fruit development and flower bud differentiation.

Fertilization precautions.

1. The application should be simple.

Peach is a shallow-rooted tree species, with most of the root system distributed at a depth of 20-30 cm. Therefore, the fertilization should be shallow, and the fertilization depth should be 30cm.

2. Fertilizer amount.

The amount of fertilizer applied should be flexibly determined according to soil fertility, tree age, variety, yield and climatic factors.

3. Keep away from the root system.

The horizontal roots of the tree are generally concentrated slightly farther from the edge of the canopy, and the growth direction of the root system is often extended due to the position of fertilization. Therefore, fertilization should be applied deeply, away from the root system, to promote the development of the root system to depth, expand the growth area and fertilizer absorption surface.

4. Supplement foliar fertilizer.

In order to prevent nutrient deficiency in peach trees, peach farmers should spray a line of foliar fertilizers based on the growth of peach trees and the nutrients of orchard soil, such as urea water + potassium dihydrogen phosphate + 1-2% superphosphate filtrate (or chelated calcium) + 2-3% plant ash filtrate (or potassium sulfate).

Generally, the plan for the year is in the spring. The quality of spring management of Taoyuan directly determines the yield and quality of Taoyuan this year. Spring coincides with the peach buds and flowering period, which requires a lot of nutrient protection, so fertilization must be implemented as soon as possible.

1. The best time for peach trees to apply basal fertilizer is generally in autumn, that is, about 1 month before the peach tree leaves fall, generally to apply organic fertilizer, the amount of organic fertilizer is relatively small, the amount of nitrogen fertilizer can be determined according to the size of the age, growth, and fertility of the soil. The amount of nitrogen fertilizer in the general base fertilizer accounts for about 40%-60% of the total amount of fertilizer applied in the year, and can generally be dug a shallow ditch under the tree to apply.

2. Top dressing after flowering, generally can be carried out before flowering in early spring, the fertilizer is mainly nitrogen fertilizer, accounting for about 10% of the amount of fertilizer applied in the year, and can be carried out at the same time as irrigation after spring, if the amount of base fertilizer in autumn is relatively high, or the base fertilizer is applied in winter, then the flowering fertilizer can not be applied, or less applied.

3. Top dressing during the fruit setting period, generally can be topdressed after flowering to before the hardening of the fruit core, which is conducive to improving the fruit setting rate, improving the nutrition of the tree and promoting the rapid growth of the fruit in the early stage, mainly applying nitrogen fertilizer, with a small amount of phosphorus and potassium fertilizer, the dosage accounts for about 10% of the application amount of the year.

4, the fruit expansion period of top dressing, in the fruit again into the rapid growth period after the top dressing, generally late varieties of fruit expansion period and flower bud differentiation period is basically consistent, at this time top dressing to promote the rapid growth of the fruit, promote the flower buds of the empty delay to change the differentiation, for the second year of production to lay a good foundation is of great significance, mainly nitrogen fertilizer, at the same time, according to the soil conditions, with the application of the appropriate amount of potassium fertilizer, the application amount accounts for about 20%-30% of the application amount of the year.

5. Top dressing after harvesting, chasing 1 fertilizer after harvesting peaches, generally with phosphorus and potassium fertilizer, and then with nitrogen fertilizer, it is beneficial to supplement the consumption of tree nutrition, and at the same time strengthen the accumulation of tree nutrition, improve the winter ability of peach trees, and ensure continuous high yield in the second year.

6. The peach fruit is juicy, can be eaten raw or made into preserved peaches and canned food, etc., the kernels can also be eaten, the flesh is white and yellow, there are many varieties of peaches, the general peel has a hairy bucket, and the peel of "nectarine" is smooth; The fruit of the "peach" is flattened; "Peach" is an ornamental peach tree with various forms of petals, and peaches are native to China and are widely cultivated in various provinces and regions.

Peach tree topdressing time.

1. Base fertilizer of peach trees: peach trees can apply a base fertilizer in autumn, and apply it in combination with autumn turning before and after the peach tree leaves fall, and dig a ditch with a depth of 40 cm under the tree, and then apply it.

2. Top dressing of peach trees: peach trees can be topdressed 2-3 times a year, mainly with fast-acting nitrogen fertilizer, with a small amount of phosphorus and potassium fertilizer, if it is a high-yield garden, it can also be applied 1-2 times.

What fertilizer is used for top dressing of peach trees.

1. On the basis of applying basal fertilizer, 1 2 of the total amount of nitrogen fertilizer is used as top dressing, before the peach tree blooms and after the fruit is harvested, the amount of top dressing accounts for a quarter of the total amount of nitrogen fertilizer, and the ternary compound fertilizer can also be applied once before flowering and physiologically after fruit dropping, and the amount of fertilizer is one-third of the total amount each time.

2. Peach trees are more sensitive to trace elements, need to carry out root topdressing, spray boric acid solution at the early flowering stage, can improve the fruit setting rate, late August to early September, spray potassium dihydrogen phosphate solution 1 time, can enhance cold resistance, spray calcium nitrate solution in the rapid expansion period of the fruit, can improve the hardness of the fruit.

Urea or compound fertilizer for top dressing of peach trees.

Peach tree fertilization organic fertilizer and urea can be applied at the same time, can be mixed, but should be used immediately after mixing, otherwise the fertilizer is easy to re-damp, especially after the organic fertilizer and urea are mixed, about 10 minutes will appear damp and agglomerate.

Peach tree topdressing method.

1. Top dressing before germination: Top dressing can be carried out before the peach tree heats up after the shed, mainly to supplement nutrients to make it better germinate and flower, which has a good role in promoting the continued differentiation of flower buds and improving the fruit setting rate.

2. Top dressing after flowering: peach trees can be topdressed during the fruit setting period after flowering, at this time, peach trees consume a lot of stored nutrients due to germination and flowering, and the growth of young fruits and new shoots is faster, and the two are prone to the contradiction of virtual orange in nutrient demand, so it is necessary to supplement fast-acting nitrogen fertilizer, with phosphorus and potassium fertilizer, to promote the expansion of young fruits and the growth of new shoots.

3. Top dressing before harvesting: Top dressing can be carried out one month before the harvest of peach tree fruits, mainly phosphorus and potassium fertilizers, the purpose of which is mainly to promote the rapid growth of fruit cells and increase the intercellular space, so as to increase the number of fruits, improve yield and improve quality.

4. Top dressing after fruit harvest: After the peach tree is harvested, it can be topdressed, which can promote the growth of roots and new shoots, restore the tree potential, make the branches and buds full and full, increase the storage of nutrients in the tree, and lay a good material foundation for the bumper yield of the next year. Fertilizers are better with nitrogen, phosphorus and potassium compound fertilizers.

The best time for autumn basal fertilizer application of peach trees is from early September to early October, with 3000-4000 kg of well-rotted farmhouse fertilizer, 80-120 kg of compound microbial fertilizer, 25-50 kg of medium and micro fertilizer, and 40-50 kg of nitrogen, phosphorus and potassium compound fertilizer.

Dig a ring ditch or strip ditch along the drip line of the canopy, with a depth of about 30 cm and a width of 40 cm, and water it after application, which is conducive to fertilizer decomposition and root absorption.

Improve the soil, cultivate soil fertility, inhibit pathogens, and improve plant stress resistance.

Summary. Glad for your question. Here is to help you find out the fertilization time of peach trees, there are three main ones, which are fertilization before budding in spring, fertilization after flowering and fertilization during the hard core period.

The method of fertilization is mainly the irrigation method, after diluting the fertilizer with water, it can be directly watered to the roots of the plant, and the fertilizer applied is usually mainly nitrogen fertilizer. However, fertilization in the hard core period also needs to add some phosphorus and potassium fertilizer, which can promote the expansion of peach fruits and lay a good foundation for the next year's fruit. Hope mine can help you.

Two-year-old peach trees (which have not been fertilized) need to be fertilized now?

Proper fertilization can be done, but autumn fertilization is recommended.

There is also the second year of plum trees, this year there is no fertilization, how to deal with the problem of fertilization now?

Plum trees are also recommended to apply autumn fertilizer, early autumn fertilization, the root system is at the peak of growth, broken roots are easy to heal and grow, fertilizer decay, decomposition time is sufficient, the degree of mineralization is high, can be absorbed and utilized by fruit trees in time; It can also increase soil temperature and reduce root frost damage; Some of the fertilizer can be absorbed by the tree in the same year, which is conducive to the production and storage of organic nutrients.
