Slow-release fertilizer used for pear tree and capable of preventing and treating root rot disease, and preparation method thereof

Abstract

The invention relates to a slow-release fertilizer used for a pear tree and capable of preventing and treating a root rot disease. The slow-release fertilizer is characterized by being prepared from the following raw materials in parts by weight: 50 parts of soybean straws, 40-50 parts of rice straws, 30-40 parts of bentonite, 20-30 parts of potassium permanganate, 40-50 parts of urea, 30-40 parts of ammonium dihydrogen phosphate, 20-30 parts of potassium sulfate, 20-25 parts of corn starch, 10-12 parts of trichloroacetic acid, 18-20 parts of 1,2-ethylidene dithiocarbamate, 20-25 parts of dichlorotetraamine complex copper, 6-8 parts of sodium stearate, 70-80 parts of methacrylic acid, 20-30 parts of sodium hydroxide, 60-70 parts of acrylamide, 20-25 parts of a potassium persulphate solution, 30-40 parts of 1,2-dicarboxylate cyclohexane and a proper amount of deionized water. The slow-release fertilizer used for the pear tree and capable of preventing and treating the root rot disease has the advantages of being safe, low-toxic, efficient, stable, labor and time-saving during application, and the like.

Description

Technical field [0001] The invention belongs to the field of pesticides and fertilizers, and particularly relates to a slow-release fertilizer capable of preventing and curing root rot for pear trees and a preparation method thereof. Background technique [0002] Medicinal fertilizer is a compound of pesticide and fertilizer produced by mixing pesticide and fertilizer in a certain proportion formula through a certain process. Modern agriculture and large-scale agriculture are supported and driven by powerful technologies. In order to realize the sustainable development of agriculture, medical fertilizer is a new attempt. Carrying out research on pesticides and fertilizers, combining the two agricultural activities of pesticides and fertilizers into one, which not only saves labor, time and energy, but also greatly reduces production costs, and reduces the amount of pesticides and fertilizers to obtain the best application Effect, thus making a great contribution to protecting th...

Problems solved by technology

The herbicidal granule fertilizer mixture prepared by this process has a short duration of action, although it has high encapsulation rate and strength, fast disintegration speed in water, and no antagonistic degradation between fertilizer and pesticide components.
