Planting techniques of Peach trees
How are peach trees planted? Speaking of peach, I believe we are no stranger to it. It is very popular all over the country. Let's take a look at how peach trees are planted.
Cultivation techniques:
1. It is best to plant in autumn before the soil is frozen, so that the seedlings first root and then sprout in spring, with high survival rate and prosperous growth after germination, which is conducive to the cultivation of strong seedlings in the first year.
2. In the first year, plastic management is the key. After the seedlings germinate, keep a main branch to grow upward, pay attention to spraying to prevent pests from invading the terminal bud, and cut off the side branches whose thickness is more than half of the main branches at any time, so as to prevent the lateral branches from competing with the main branches for nutrients and affect the upward growth of the trunk, leaving branches from 40 cm at the base of the trunk. Nitrogen fertilizer urea was applied several times in the early and middle stages to promote the rapid growth of seedlings, which could grow to more than 2.5 meters in the same year.
After March and August, stop using nitrogen fertilizer, topdressing phosphorus and potassium fertilizer, twisting and pulling branches on the opposite side, properly spraying plant growth regulators, such as paclobutrazol, dwarf, etc., according to the tree potential, in order to control the vigorous growth and promote the formation of flower buds and lay a good foundation for the results of the second year.

The pollination method of peach trees is fast and good.
Artificial pollination and artificial pollination can be used. Although peach trees can bear fruit by self-pollination, peach trees with cross-pollination have high fruit setting rate, good quality and high yield. When cultivated in greenhouse, cross-pollination is possible because of poor air mobility, low temperature and high humidity in greenhouse.
