Soil-improving compound fertilizer for planting sweet potatoes and preparation method of compound fertilizer

Abstract

The invention discloses a soil-improving compound fertilizer for planting sweet potatoes and a preparation method of the compound fertilizer. The compound fertilizer comprises the following raw materials in parts by weight: 10-16 parts of potassium dihydrogen phosphate, 13-20 parts of calcium superphosphate, 25-35 parts of ammonium sulfate, 8-16 parts of animal manure, 15-21 parts of choline chloride, 17-25 parts of biological fermented cotton meal, 10-16 parts of lactobacillus plantarum dry powder and 20-27 parts of buckwheat flour. The invention also provides the preparation method of the soil-improving compound fertilizer for planting the sweet potatoes. The compound fertilizer provided by the invention has the advantages of reasonable formula, low cost, and scientific and practical production process; the preparation method has simple process and is suitable for large-scale industrial production; and the compound fertilizer can change defective conditions of soil hardening, poor air permeability and the like, has long-lasting fertilizer effect and quick effect, is especially suitable for root and tuber plants, and can effectively improve the yield and quality of the root and tuber plants.

Description

technical field [0001] The invention relates to the technical field of compound fertilizers, in particular to a compound fertilizer for sweet potato planting which improves soil and a preparation method thereof. Background technique [0002] Roots, tubers, and plants that eat underground parts are very susceptible to pests and diseases. At present, chemical fertilizers used to prevent pests and crops in agriculture are mainly mixed with chemical agents and toxic pesticides, and then applied to the soil or crops for a long period of time year after year. The use of a large amount of pesticides and chemical fertilizers leads to the development of drug resistance of pests, soil compaction, pollution of water sources, soil and crops, decline in the quality of agricultural products, and excessive pesticide residues, seriously affecting people's physical and mental health and the competitiveness of my country's agricultural products in the international market. In addition, the cur...

[0002] Roots, tubers, and plants that eat underground parts are very susceptible to pests and diseases. At present, chemical fertilizers used to prevent pests and crops in agriculture are mainly mixed with chemical agents and toxic pesticides, and then applied to the soil or crops for a long period of time year after year. The use of a large amount of pesticides and chemical fertilizers leads to the development of pesticide resistance of pests, soil compaction, pollution of water sources, soil and crops, decline in the quality of agricultural products, and excessive pesticide residues, seriously affecting people's physical and mental health and the competitiveness of my country's agricultural products in the international market.

In addition, the current average utilization rate of compound fertilizers is low, the loss of nutrients is serious, and it is easy to cause pollution to groundwater and rivers and lakes; conventional fertilizers are generally not easy to control the release rate of each nutrient, so that the release rate can be synchronized with the progress of crops absorbing fertilizer, so if Applying a large amount of fertilizer at one time is easy to cause burnt seedlings at the seedling stage, and it is often difficult to apply fertilizer multiple times due to the limitation of human cultivation conditions, resulting in poor growth of crops due to lack of fertilizer
