What aspects should be paid attention to in topdressing peach trees?

Because the soil climatic conditions and tree growth and fruit conditions are different in different places, the time and times of topdressing peach trees should be flexibly controlled according to the development of peach trees, soil conditions and variety yield, but some growers apply fertilizer blindly. As a result, the yield of peach is not high. Today, the editor of Green Food Network introduces to growers some aspects that need to be paid attention to in topdressing peach trees.

Peach tree

Look at the tree

Fertilize the age, growth and yield of peach trees. The combination of root fertilization and foliar spraying is generally adopted. In order to continue to supplement the nutrition of peach trees, 0.4-0.6 kg compound fertilizer was applied to adult trees according to the fertilizer application period. Such as topdressing after flowering, the root is mainly applied with available nitrogen fertilizer, supplemented by foliar spraying of boron; such as topdressing before fruit harvest, the root is mainly applied with rapidly available potassium; if supplementary fertilizer is adopted, nitrogen fertilizer and phosphorus fertilizer can be applied mainly from September to October after harvest.

Look at the land

Look at the structure and fertility of vineyard soil to determine the type, quantity and method of topdressing. For example, in sandy soil, the content of organic matter is low, the structure and performance is poor, and the leakage of water and fertilizer is serious. For peach trees growing in sandy soil, 60 kg of high quality ring fertilizer mixed with 0.4-0.6 kg of chemical fertilizer is applied to each plant.

Look at the output

Fertilize according to the yield. The trees with large fruit quantity must have enough fertilizer with reasonable combination of nitrogen, phosphorus and potassium to keep the diameter of the extended branch of the peach tree at 1.0-1.5 cm. Under normal conditions, for every 100 kg of peach per tree, available nitrogen fertilizer 0.7-0.8 kg, phosphate fertilizer 0.5-0.6 kg, potash fertilizer 1-1.5 kg.
