When is the time to fertilize peach trees and what is the most appropriate fertilizer?

Base fertilizer: base fertilizer was applied about one month before the defoliation of peach trees, mainly organic fertilizer. Topdressing after flowering: topdressing before flowering after early spring, mainly applying nitrogen fertilizer. Topdressing in fruit setting period: topdressing after flowering to before hardening of fruit core, mainly applying nitrogen fertilizer. Topdressing in the fruit expansion period: topdressing after the fruit entered the rapid growth period again, mainly applying nitrogen fertilizer. Topdressing after harvest: after harvesting peaches, you should apply fertilizer once, mainly applying phosphorus and potassium fertilizer, and then cooperate with nitrogen fertilizer.

1. Base fertilizer

The main results are as follows: 1. the better time for peach trees to apply base fertilizer is generally in autumn, that is, about one month before peach leaves fall, which is mainly organic fertilizer, and when the amount of organic fertilizer is relatively small, the amount of nitrogen fertilizer can be determined according to the tree age, growth and soil fertility.

2. The amount of nitrogen fertilizer applied in the general base fertilizer accounts for about 40% 60% of the total amount of fertilizer applied in the current year, and it can generally be applied in shallow trenches under the tree. when you need to pay attention to fertilization, do not get too close to the tree, and the fertilizer should be properly mixed with the soil to avoid root burning.

Second, topdressing after flowering

Generally, topdressing can be carried out before flowering after early spring, and the fertilizer is mainly nitrogen fertilizer, accounting for about 10% of the amount of fertilizer applied in the same year, which can be carried out at the same time as irrigation after the beginning of spring. If the amount of base fertilizer is relatively high in autumn, or the base fertilizer is applied in winter, then flower-promoting fertilizer can not be applied, or less.

Third, topdressing during fruit setting period

Generally, fertilizer can be applied after flowering to before nuclear hardening of the fruit, which is beneficial to increase the fruit setting rate, improve tree nutrition and promote the rapid growth of fruit in the early stage, mainly applying nitrogen fertilizer, combined with a small amount of phosphorus and potassium fertilizer, accounting for about 10% of the amount applied in the same year.

4. Topdressing during fruit expansion

After the fruit enters the rapid growth period again, the fruit expansion period of the general mid-and late-maturing varieties basically coincides with the flower bud differentiation period. At this time, topdressing can promote the rapid growth of fruit, promote the differentiation of flower buds, and lay a good foundation for the second year's production, mainly nitrogen fertilizer. At the same time, according to the soil conditions, the appropriate amount of potassium fertilizer can be applied, accounting for about 20% of the current year's application.

5. Topdressing after harvest

The main results are as follows: 1. Fertilizer should be applied once after peach harvest, mainly by applying phosphorus and potassium fertilizer, and then combined with nitrogen fertilizer, which is beneficial to supplement the consumption of tree nutrition, at the same time, strengthen the accumulation of tree nutrition, improve the ability of peach trees to survive the winter, and ensure the continuous high yield in the second year.

2. The peach fruit is succulent and can be eaten raw or made into preserved and canned peaches. The flesh is white and yellow. There are many kinds of peaches with hairy skin, while the peel of "nectarine" is smooth. "flat peach" fruit is a flat disk-shaped peach tree with various forms of petals. Peaches are native to China and are widely planted in various provinces.
