Topdressing in peach growth period should be determined according to the age and growth period of fruit trees. Generally, pre-bud fertilizer, fruit-strengthening fertilizer and post-harvest fertilizer are mainly used to ensure adequate water and fertilizer supply, balanced fertilization and no partial application of nitrogen fertilizer, so as to ensure sufficient nutrients needed for plant growth, high yield and high quality.

Reasonable fruit thinning is an effective way to improve the fruit setting rate and fruit quality of peach. The first fruit thinning can be carried out 20-25 days after flowering, and the second fruit setting can be carried out after physiological fruit dropping, that is, from early May to mid-May, mainly to remove diseases and pests, diseased fruits, deformed fruits, small fruits and double fruits, so as to reduce useless consumption of nutrients and cultivate strong fruits and high-quality fruits. For the first fruit trees and flourishing trees, it is advisable to leave more fruits to crush the trees with fruits.

When the diameter of young fruit grows to about 5- 10mm, spray the film without bag for the first time, then spray it for the second time at an interval of about 7- 10 days to supplement the places not sprayed in the first time, and spray it for the third time at an interval of about 30 days to enhance the effect. Although the fruit cultivated with non-bagging film is not as good-looking as bagged fruit, it is more delicious than bagged fruit, and it is a better choice for selling peaches online.
