Organic rice fertilizer

Abstract

The invention discloses organic rice fertilizer. The organic rice fertilizer is prepared from, by weight, 12-13% of corn straw, 17-19% of bean straw, 2-3% of indolebutyric acid, 5-7% of nitrogen, 5-7% of phosphorus pentoxide, 7% of potassium oxide, 0.3-0.5% of zinc, 0.3-0.5% of silicon, 0.1-0.2% of chrome, 14-19% of livestock and poultry excrement, 12-15% of urea, 4-7% of ammonium bicarbonate and 6-8% of zinc sulfate. The organic rice fertilizer promotes rice plant growth and cell wall thickening, improves disease resistance, insect resistance and lodging resistance, and an active functional group has the functions of chelating and buffering nutrient elements; the fertilizer use ratio is increased, fertilizer loss is reduced, matching is scientific, the use ratio of nutrients is ensured, medium trace element zinc and beneficial element silicon are added, the yield per mu is increased by 10-20% than that of conventional fertilizer application, and the organic rice fertilizer has good economic benefits.

Description

technical field [0001] The invention relates to an organic rice fertilizer. Background technique [0002] Reasonable fertilization can not only increase yield, improve crop quality, but also keep soil nutrients in balance, which is conducive to fertilizing soil fertility. However, in the prior art, rice fertilization is mostly based on conventional elemental fertilizers such as urea, ammonium bicarbonate, and diammonium phosphate. Long-term application of simple fertilizers will have adverse effects on soil and crops. In the prior art, the development from farmyard manure to chemical fertilizer, the application of chemical fertilizer has led to a rapid development of agricultural production, but chemical fertilizer pollutes the environment, compacts the soil, destroys the soil structure, and makes many beneficial organisms in the soil gradually extinct, resulting in the decline of soil fertility , Deterioration of crop quality and other defects. Planting paddy fields year...

Long-term application of simple fertilizers will have adverse effects on soil and crops

In the prior art, the development from farmyard manure to chemical fertilizer, the application of chemical fertilizer has led to a rapid development of agricultural production, but chemical fertilizer pollutes the environment, compacts the soil, destroys the soil structure, and makes many beneficial organisms in the soil gradually extinct, resulting in the decline of soil fertility , crop quality deterioration and other defects

Planting paddy fields year after year not only absorbs a large amount of nitrogen, phosphorus, potassium and a certain amount of calcium, magnesium, sulfur, iron and other elements from the soil every year, but also absorbs a small amount of chlorine, zinc, manganese, boron, and copper. Molybdenum, molybdenum and other trace elements are about 10 times that of nitrogen. A large amount of various nutrients are absorbed, and some are lost by leaching. The supplement of inorganic fertilizers alone is far from meeting the needs of rice production.
