Special organic fertilizer for corn

Abstract

The invention discloses a special organic fertilizer for corn, and belongs to the technical field of chemical fertilizers. The special organic fertilizer comprises the following materials in parts by weight: 20 to 25 parts of humic acid, 10 to 15 parts of asparaginic acid, 10 to 15 parts of bean pulp, 10 to 16 parts of potassium chloride, 40 to 50 parts of bentonite, 30 to 40 parts of silkworm excrement, 35 to 45 parts of grain stillage, 10 to 15 parts of gelatin, 10 to 15 parts of urea, 20 to 30 parts of diammonium orthophosphate, 20 to 30 parts of chicken feathers, 4 to 6 parts of carboxymethylcellulose, 1 to 2 parts of zinc sulfate, 1 to 2 parts of ferrous sulphate, 1 to 2 parts of borax, 2 to 5 parts of a wilfordine preparation, 2 to 5 parts of a stemonine preparation, 2 to 5 parts of nanometer iron-ore slag powder, 3 to 4 parts of wintergreen oil, 2 to 4 parts of azospirillum brasilense, 1 to 3 parts of bacillus licheniformis, and 4 to 6 parts of EM bacteria. The special organic fertilizer is reasonable in formula, more comprehensive and balanced in nutrients and good in use effect, can obviously improve the fertilizer efficiency utilization ratio, and greatly improves the corn yield and quality, thereby improving the economic benefit of corn.

Description

technical field [0001] The invention relates to a special organic fertilizer for corn and belongs to the technical field of chemical fertilizers. Background technique [0002] Corn, Poaceae, and Zea mays are annual tall herbs. Culms erect, usually unbranched, with aerial strut roots at base nodes. Leaf sheaths with transverse veins; ligule membranous, about 0.2m long; blade flat and broad, linear-lanceolate, base rounded and ear-shaped, glabrous or pilose, midrib stout, margin slightly scabrous, about 1- 1.5 m. The caryopsis is spherical or oblate, and the glumes and lemmas are exposed after maturity. Its size varies with different growth conditions. It is cultivated in various parts of my country. It is widely planted in tropical and temperate regions of the world and is an important cereal.

AI Technical Summary

Problems solved by technology

[0003] At present, corn pests and diseases are mainly controlled by mixing and stirring chemical agents and toxic pesticides, applying them to the soil or crops, and using them for a long time year after year. A large amount of pesticides and fertilizers will cause the pests to develop resistance, soil compaction, and damage to water sources. Pollution of soil and crops, decline in the quality of agricultural products, and excessive pesticide residues seriously affect people's physical and mental health and the competitiveness of my country's corn in the international market
