Composite fertilizer with durable fertilizer effect and applied to sweet potato planting as well as preparation method thereof

Abstract

The invention discloses composite fertilizer with a durable fertilizer effect and applied to sweet potato planting as well as a preparation method thereof. The composite fertilizer comprises the following raw materials in parts by weight: 10 to 16 parts of monopotassium phosphate, 13 to 20 parts of calcium superphosphate, 25 to 35 parts of ammonium sulfate, 8 to 16 parts of animal excrement, 15 to21 parts of traditional Chinese medicine powder, 17 to 25 parts of composite vitamin, 10 to 16 parts of lactobacillus plantarum dry powder and 20 to 27 parts of cinnamon powder. The invention also provides a preparation method of the fertilizer with the durable fertilizer effect and applied to sweet potato planting. The formula is reasonable; the cost is low; the production process is scientificand practicable; the preparation method is simple in process and suitable for large-scale industrialized production; the bad conditions of soil hardening, low air permeability and the like can be changed; and furthermore, the composite fertilizer has a durable fertilizer effect, is quick in response, is particularly suitable for root and tuberous plants, and can effectively increase and improve the yield and the quality of the root and tuberous 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 with long-lasting fertilizer effect 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 a...

[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
