Fertilizer for resisting peach tree leaf curl disease

Abstract

The invention discloses fertilizer for resisting peach tree leaf curl disease. The fertilizer is prepared from the following raw materials in parts by weight: 8 to 10 parts of urea, 7 to 8 parts of potassium chloride, 6 to 8 parts of ammonium phosphate, 10 to 15 parts of potassium humate, 1 to 2 parts of calcium humate, 3 to 4 parts of ferric humate, 2 to 3 parts of magnesium amino acid, 0.5 to 1 part of trace elements, 7 to 9 parts of traditional Chinese medicinal extracts, 0.5 to 1 part of modifier, 3 to 4 parts of additive and 25 to 30 parts of water. According to the fertilizer disclosed by the invention, by matching various substances, germs are killed and the disease is controlled from the outside, and the own disease resistance of peach trees is activated and strengthened from the inside while proper nutrients are provided; in addition, the traditional Chinese medicinal extracts are promoted to enter the inside of the peach trees and are matched with the modifier, so that the disease resistance of the peach trees is greatly improved, the germs are killed, and further the peach tree leaf curl disease is thoroughly treated from inside to outside.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a fertilizer resistant to peach tree leaf shrinkage disease. Background technique [0002] Peach is delicious and loved by people, but when peach trees are planted, some diseases often appear, which affect the yield and quality of peaches. Among them, leaf shrinkage is a common disease of peach trees. [0003] Leaf shrinkage is a fungal disease.

Problems solved by technology

[0005] At present, antibacterial agents are often used to kill peach tree leaf shrinkage by spraying antibacterial agents. Although chemical agents can prevent leaf shrinkage to a certain extent, the long-term and large-scale use of agents will increase the drug resistance of the bacteria and cause There are drug residues, affecting the quality and safety of peaches, and polluting the environment at the same time
