Special base fertilizer for late rice

Abstract

The invention discloses a special base fertilizer for late rice. The special base fertilizer is prepared from the components of Chinese medicine residues, decomposed coal, attapulgite, ghem, urea, calcium superphosphate, potassium chloride, duck feather, carboxymethyl cellulose, 30% sulfuric acid, lime, zinc sulfate, copper sulfate, boric acid, buddleia powder, gelatin, nanometer calcium carbonate powder and wintergreen oil according to a certain weight ratio. According to the special base fertilizer, the feather is subjected to acid hydrolysis to generate amino acid, then mid-elements and trace elements are subjected to chelation, and the carboxymethy cellulose can be used for enhancing the chelation structures of the mid-elements and the trace elements, thereby being beneficial to the effective utilization of the mid-elements and the trace elements, and reducing the ineffective release of the mid-elements and the trace elements; according to the formula disclosed by the invention, the attapulgite serving as an inorganic controlled-release composition and the decomposed coal serving as a soil improvement composition can be used for improving soil, thus being beneficial to the effective release of the fertilizer and the adequate absorption of crops; and the buddleia powder serving as a biologic insecticide composition can effectively reduce plant diseases and insect pests on the soil, is safe and pollution-free and has on pollution on an environment and the crops. The special base fertilizer has the reasonable formula and a good use effect, is relatively comprehensive and balanced in nutrition, and can obviously improve the fertilizer utilization efficiency and greatly improve the yield and the quality of the late rise so as to improve the economic benefits of the late rice.

Description

technical field [0001] The invention relates to a special fertilizer for late rice base fertilizer, which belongs to the technical field of agricultural fertilizers. Background technique [0002] my country is a large agricultural country. Chemical fertilizers and pesticides play a very important role in agricultural production. With the improvement of people's living standards and health awareness, people attach great importance to the safety of agricultural products, and the demand for pollution-free and green food is increasing year by year. . [0003] There are many types of fertilizers currently used for late rice planting, and most of the special fertilizers for late rice are NPK compound fertilizers available on the market, which are mainly composed of three inorganic elements, N, P, and K, which can meet the growth needs of late rice in a short time. However, long-term use will destroy the soil aggregate structure, easily cause soil compaction and soil hardening, the...

AI Technical Summary

Problems solved by technology

However, long-term use will destroy the soil aggregate structure, easily cause soil compaction and soil hardening, thus affecting the growth of late rice, and the promotion effect on the growth of late rice is not obvious

At the same time, although pure organic fertilizer is rich in organic matter, it releases nutrients slowly, absorbs slowly in late rice, and has low fertilizer efficiency. Effective balance of various effective nutrients cannot be achieved.

[0004] At present, the prevention and control of diseases and insect pests in late rice is mainly to use chemical agents and toxic pesticides to mix and stir, apply them to the soil or crops, and use them for a long time year after year. A large amount of pesticides and fertilizers will cause the pests to develop drug resistance, soil compaction, and damage to water sources. Pollution of soil and crops, decline in the quality of agricultural products, and excessive pesticide residues seriously affect people's physical and mental health and the competitiveness of my country's late rice in the international market
