Compound fertilizer for soil improvement

Abstract

The invention discloses a compound fertilizer for soil improvement. The compound fertilizer is characterized by containing the following substances in parts by weight: 0.01-0.02 part of azotobacter powder, 21-30 parts of sweet potato flour, 45-50 parts of peat, 9-16 parts of calcium superphosphate, 0.01-0.02 part of bacillus sphaericus powder, 40-50 parts of rice straws, 3-7 parts of potassium polymetaphosphate, 8-13 parts of ammonium dihydrogen phosphate, 0.01-0.02 part of bacillus siliceous, 0.03-0.07 part of bacillus cereus, 6-7 parts of litchi seed, 3-5 parts of shelled cedar seed, 0.001-0.002 part of bacillus thuringiensis, 20-25 parts of chicken manure and 19-26 parts of wheat bran. The compound fertilizer disclosed by the invention integrates production increase, high efficiency, long acting, quality improvement, soil improvement and soil-borne disease inhibition, is low in cost and simple in process, is residue-free and pollution-free and has relatively good popularization and application prospects.

Description

technical field [0001] The invention relates to a compound fertilizer for improving soil. Background technique [0002] At present, in terms of crop planting in my country, most of them still use chemical fertilizers. Although they have a certain effect on increasing production and income, long-term application will cause many disadvantages: 1. Destroy the soil, resulting in a decline in soil organic matter content and imbalances in the proportion of various nutrients. The soil begins to acidify and compact, and the physical and chemical properties of the soil and soil microbial flora are severely damaged, resulting in poor water retention, fertilizer retention, and air permeability, which are difficult to meet the actual growth needs of crops; 2. Crops are highly dependent on chemical fertilizers and pesticides, and must Increase the amount of period use year by year, otherwise, the crops will grow slowly, and the pests and diseases will be serious, resulting in reduced produ...

Destroy the soil, resulting in a decline in soil organic matter content and imbalances in the proportion of various nutrients.

Crops are highly dependent on chemical fertilizers and pesticides, and must Increase the amount of period use year by year, otherwise, the crops will grow slowly, and the pests and diseases will be serious, resulting in reduced production; 3. The agricultural ecological environment will deteriorate. After the chemical fertilizers are applied to the farmland, the actual utilization rate is only 30% on average, and most of them will flow into rivers and lakes with farmland drainage or remain in The soil, plants and crops not only bring environmental pollution but also endanger the safety and health of human beings and life, which have become obstacles to the sustainable development of agriculture
