Abstract

The invention belongs to the technical field of plant fertilizer preparation, and particularly relates to a special nutrient solution for preventing and controlling peach tree yellowing and preparation and application thereof.The nutrient solution is composed of multiple nutrient elements and plant hormones which are needed by peach tree growth and development, the leaf quality and the adversity stress resisting capacity of peach trees are improved by improving the physiological metabolism function of trees and regulating the nutrient growth condition, the obvious effects on improving the fruit quality and increasing the fruit yield are achieved, and peach tree yellowing can be thoroughly cured after the nutrient solution is continuously used for 2 years; the nutrient solution can be used in the peach tree growth seasons, cannot cause leaf falling and fruit falling of the peach trees and is high in safety.

Description

technical field [0001] The invention belongs to the technical field of plant fertilizer manufacture, and in particular relates to a special nutrient solution for preventing and treating yellowing of peach trees and its preparation and application. Background technique [0002] Peach is widely cultivated and is the third largest deciduous fruit tree in my country. Its fruit is juicy and delicious, and it is a traditional fruit loved by people in our country. According to the data of the Food and Agriculture Organization of the United Nations, in 2013, my country's peach cultivation area was 11.66 million mu, and the output was 11.95 million tons, accounting for 50.5% and 55.2% of the world's total respectively. [0003] Chlorosis is an important physiological disease in the production of peach trees in my country. It can cause tree vigor to weaken, fruit size to become smaller, lead to a decline in yield and quality, and even the entire orchard to fail. In the prior art, fru...
