Problems solved by technology

At present, chemical fertilizers on the market can meet the growth needs of corn in a short period of time, but long-term use will damage the soil aggregate structure, easily cause soil compaction, and soil hardening, thus affecting the growth of corn
At present, corn pests are mainly controlled by mixing and stirring chemical agents and toxic pesticides, applying them to the soil, and using them for a long time year after year, resulting in insect resistance, soil compaction, pollution of water sources, soil and crops, and poor quality of agricultural products. Decline, excessive pesticide residues seriously affect people's physical and mental health and the competitiveness of my country's corn in the international market

Abstract

The invention discloses a green organic fertilizer for preventing corn pests. The fertilizer is prepared from the following raw materials in parts by weight: 100-150 parts of cow dung, 70-80 parts ofchicken manure, 50-60 parts of corn straw, 30-40 parts of bacterial residue, 10-20 parts of earthworm dung, 1-3 parts of EM microbial inocula, 3 parts of synergists, 2 parts of composite leavens and 20-30 parts of attapulgite. The invention further discloses a green organic fertilizer preparation method. The green organic fertilizer for preventing corn pests is reasonable in composition, is environment-friendly and effective, enables the soil to be loose and breathable, effectively improves the hardening state of the soil, promotes the activity of soil microorganisms, forms a reasonable soilflora structure, can further provide a large amount of nutrient components for corn, promotes the growth and development of the corn and enhances the resistance of the corn.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a green organic fertilizer for preventing corn pests and a preparation method thereof. Background technique [0002] my country is a large agricultural country, and corn is the third largest economic crop in my country, occupying an important position in agricultural production. Chemical fertilizers and pesticides play a very important role in agricultural production. With the improvement of people's living standards and health awareness, people pay more and more attention to the safety of agricultural products, and the demand for pollution-free and green food is increasing year by year. Excessive use of chemical fertilizers in my country's agriculture can easily lead to a decline in land fertility and soil compaction. Most of the nutrients contained in organic fertilizers are in an organic state. Through the action of microorganisms, a variety of nutrients are s...
