Special nutritive fertilizer for apple trees and preparation method of special nutritive fertilizer

Abstract

The invention discloses a special nutritive fertilizer for apple trees. The special nutritive fertilizer is prepared from the following raw materials in parts by weight: 140-160 parts of edible mushroom residues, 100-120 parts of sawdust, 100-120 parts of rape seed cakes, 60-70 parts of chaff, 30-34 parts of diatomite, 55-60 parts of ammonium dihydrogen phosphate, 16-19 parts of potassium chloride, 3-4 parts of zinc sulfate, 2-3 parts of sodium selenite, 3-4 parts of magnesium sulfate, 3-4 parts of borax, 3-4 parts of ferric chloride, 1-2 parts of sodium diacetate, 6-9 parts of EM(Effective Microorganism) fungicide and 10-15 parts of soil conditioner. The fertilizer disclosed by the invention can be used for conditioning soil, overcoming the defect of soil hardening, improving the soil air permeability, reducing the loss and evaporation of water, relieving the drought load, conserving manure, increasing the soil fertility and ensuring that the yield of applies is greatly increased. In addition, the added diatomite contains SiO2 as the main chemical component and also contains a small quantity of Al2O3, Fe2O3, CaO, MgO, K2O, Na2O, P2O5 and organic matters. The special nutritive fertilizer has the advantages of fineness, looseness, light weight, porosity, strong water absorption and permeability, no toxicity, good suspension property, strong adsorption property and the like, and plays roles in preserving moisture, loosening the soil, prolonging the pesticide and fertilizer effect time and promoting the growth of crops in soil.

Description

[0001] technical field [0002] The invention relates to the technical field of fertilizers, in particular to a special nutrient fertilizer for apple trees and a preparation method thereof. Background technique [0003] Apples are perennial crops, rich in potassium, magnesium, zinc and other trace elements, not only good for the body, but also beautify the skin. For the yield and quality of fruit, fruit farmers water, fertilize, and eliminate insects to ensure the water and nutrients needed for their growth. However, traditional fertilizers have certain side effects, not only bringing a certain degree of pollution to the fruit, but also polluting the soil and the surrounding environment. Long-term use will cause a large amount of fertilizer to remain on the ground, which not only causes a serious decline in soil quality, but also pollutes water bodies, threatening the sustainable development of agriculture and the living environment of human beings. And it will also lead t...
