No-chemical-residue biofertilizer

Abstract

The invention discloses a no-chemical-residue biofertilizer which comprises the following components in parts by weight: 1-2 parts of abamectin mixture, 20-31 parts of ammonium dihydrogen phosphate, 15-21 parts of calcium hydrogen phosphate, 15-25 parts of calcium phosphate, 21-32 parts of potassium dihydrogen phosphate, 11-16 parts of dipotassium hydrogen phosphate, 4-9 parts of earthworm manure, 8-13 parts of rape cake, 5-9 parts of wheat bran, 3-7 parts of yam, 1-3 parts of sucrose, 1-7 parts of agar, 70-95 parts of corn straw, 55-75 parts of bean straw, 25-35 parts of potato straw, 1-8 parts of ground phosphorite and 2-7 parts of oyster shell. The invention is suitable for various crops of vegetables, melons and fruits; after the biofertilizer is applied, the crops have good fruits and beautiful color, and can become ripe earlier; and the invention reduces the fertilizer application frequency, increases the yield and sweetness of melons and fruits, and saves the cost.

Description

technical field [0001] The invention relates to a biological fertilizer without chemical residue. Background technique [0002] Plant parasitic nematodes are important pathogens among crop pests. In addition to directly causing plant diseases, nematodes can also transmit a variety of pathogenic microorganisms, especially viruses. The average global crop loss due to plant parasitic nematodes is more than 10%. In particular, due to the rapid expansion of the area of ​​vegetables in protected areas in China, the uninterrupted planting throughout the year has caused a large accumulation of nematodes and other pathogenic microorganisms, resulting in reduced vegetable production, and seriously affected the quality and export of vegetables, seriously threatening the production of protected vegetables. Most of the nematicides currently used are organophosphorus and carbamates, such as aldicarb, which are highly toxic pesticides, and there are very few low-toxic pesticides to choos...

Problems solved by technology

In particular, due to the rapid expansion of the area of ​​vegetables in protected areas in China, uninterrupted planting throughout the year has resulted in a large accumulation of nematodes and other pathogenic microorganisms, resulting in a reduction in vegetable production and seriously affecting the quality and export of vegetables, seriously threatening the production of vegetables in protected areas

Most of the nematicides currently used are organophosphorus and carbamates, such as aldicarb, which are highly toxic pesticides, and there are very few low-toxic pesticides to choose from. Nematodes are prone to resistance and are compatible with the environment. Extremely poor, polluting soil and water resources
