Organic fertilizer specially used for rice

Abstract

The invention belongs to the technical field of rice planting and specifically discloses an organic fertilizer specially used for rice. The organic fertilizer comprises the following ingredients in parts by weight: 32-36 parts of straws, 22-32 parts of peanut bran, 22-32 parts of soybean meal, 8-12 parts of cow dung, 12-16 parts of distillers' grains powder, 4-6 parts of earthworm powder, 4-7 parts of enzymes, 16-20 parts of urea, 12-16 parts of phosphate fertilizers, 12-16 parts of potassium fertilizers, 5-9 parts of tea residues, 4-6 parts of chitosan, 2-4 parts of humic acid, 0.5-1.5 parts of microelements, 3-5 parts of traditional Chinese medicine residues and 2-4 parts of fermentation strains. The organic fertilizer specially used for the rice is scientific and reasonable in formula, and the disease-resistant, insect-resistant and lodging-resistant capabilities of rice plants can be improved; the utilization rate of the fertilizer is improved, the loss of the fertilizer is reduced, and the utilization rate of nutrients is ensured. The organic fertilizer is applied to a rice field, the yield per mu of the rice can be effectively increased by 20-30%, and the economic benefit is good. Therefore, the organic fertilizer is suitable for popularization and use.

Description

technical field [0001] The invention belongs to the technical field of rice planting, and in particular relates to a special organic fertilizer for rice. Background technique [0002] Rice is an important food crop in my country. Its sown area and total output rank second only to wheat, and it occupies an important position in agricultural production. In recent years, due to the partial application, single application and heavy application of chemical fertilizers, fertilizer waste has been caused, and the application ratio of nitrogen, phosphorus and potassium has been seriously out of balance, resulting in the accumulation of soil salt, resulting in soil compaction, soil fertility decline, soil organic matter content decline, and pests and diseases. Seriously, it leads to a decrease in rice yield; at the same time, excess nutrients in the soil often enter the water body and the atmosphere through volatilization, leaching, and denitrification, which not only leads to a decre...

Problems solved by technology

In recent years, due to the partial application, single application and heavy application of chemical fertilizers, fertilizer waste has been caused, and the application ratio of nitrogen, phosphorus, and potassium has been seriously out of balance, resulting in the accumulation of soil salt, resulting in soil compaction, soil fertility decline, soil organic matter content decline, and pests and diseases. Seriously, it leads to a decrease in rice yield; at the same time, excess nutrients in the soil often enter the water body and the atmosphere through volatilization, leaching, denitrification, etc., which not only leads to a decrease in fertilizer utilization rate, but also leads to groundwater pollution and eutrophication of rivers and lakes
