Special fertilizer capable of improving soil structure and used for rice

Abstract

The invention discloses special fertilizer capable of improving soil structure and used for rice. The fertilizer comprises raw materials in parts by weight as follows: 40-50 parts of ammonium bicarbonate, 20-40 parts of polypotassium phosphate, 5-15 parts of sylvite, 10-18 parts of ground phosphate rock, 20-40 parts of peanut meal, 4-10 parts of fermented pig manure, 1-5 parts of pond sludge, 0.1-0.4 parts of land plaster, 0.2-0.8 parts of magnesium sulfate, 1-2 parts of potassium molybdate, 0.2-0.8 parts of zinc nitrate, 0.1-0.3 parts of ferrous sulfate, 2-9 parts of bamboo charcoal powder, 1-8 parts of diatomite and 1-2 parts of vermiculite powder. With the adoption of the special fertilizer capable of improving the soil structure and used for the rice, soil hardening and desertificationcan be eliminated step by step, organic content of soil is increased, granular structure of the soil is optimized, breeding of harmful bacteria is inhibited, sufficient nutrients are supplied, the rice grows vigorously, and the quality of the rice is high.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a special rice fertilizer for improving soil structure. Background technique [0002] Rice is an important commodity grain in our country. In addition to self-sufficiency, some of it can be exported every year. However, with the development of the economy, a large amount of surplus labor force has flocked to the city. However, due to the large amount of labor in the rice planting process, fertilizers need to be applied 2-3 times during the entire growth period, which will greatly affect the planting of rice. Farmers use a large amount of inorganic fertilizers, causing damage to the soil structure of paddy fields. Although the amount of fertilizers has increased year by year, the yield has not increased but decreased. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a special rice fertil...
