Problems solved by technology

People and animals will cause poisoning reactions after eating. Experimental observation: when 20% of diseased grains are mixed in the raw grain, the taste will be astringent and bitter when eaten by humans, and the taste will be sour and smelly. Dizziness and other symptoms; horses, mules, donkeys, pigs and other livestock have diarrhea, food refusal, and growth slowdown; sheep and chickens have decreased food intake after feeding, and the egg production rate of hens has decreased; With diseased grains, the commodity value is reduced by 0.2-0.4 yuan / kg, and with diseased grains in the seeds, the sowing rate is doubled

Abstract

The invention discloses a special double-film double-control slow-release fertilizer for corn and a preparation method thereof, belonging to the technical field of fertilizers. The special double-film double-control slow-release fertilizer for corn comprises a base fertilizer, an additional fertilizer and an ear fertilizer. The base fertilizer is prepared from the following raw materials in parts by weight on dry basis: livestock / poultry manure, wheat straw, Enteromorpha, kaolin, manioc waste, edible fungus residue, inorganic fertilizer and sterilizing component. The additional fertilizer is prepared from urea, diammonium phosphate, ammonium chloride, potassium chloride, potassium sulfate, gypsum and urea formaldehyde. The ear fertilizer is prepared from rare earth, urea, diammonium phosphate, potassium sulfate and pesticidal component. The special double-film double-control slow-release fertilizer for corn can greatly increase the corn yield and lower the occurrence of diseases and pests.

Description

technical field [0001] The invention relates to a special double-film double-control slow-release fertilizer for corn and a preparation method thereof, belonging to the technical field of fertilizers. Background technique [0002] Corn is the seed of maize, an herbaceous plant in the family Gramineae. It is planted all over China, especially in Northeast, North and Southwest provinces. According to statistics, in 2012 the United States produced 272,432 thousand tons of corn and consumed 254,444 thousand tons of corn. kilotons. Brazil is the third largest corn producer in the world with a production of 70,000 kilotons. Corn is a good health product in coarse grains, and eating corn is quite beneficial to human health. According to research, every 100 grams of corn contains 106 kcal of calories, 2.9 grams of cellulose, 4.0 grams of protein, 1.2 grams of fat, 22.8 grams of carbohydrates, and other mineral elements and vitamins. The crude fiber contained in corn is 4-10 time...
