Yield increasing and insect pest prevention slow-release fertilizer for rice, and preparation method thereof

Abstract

The invention discloses a yield increasing and insect pest prevention slow-release fertilizer for rice, and a preparation method thereof, wherein the raw materials comprise, by weight, straw powder, animal manure, plant ash, weathered coal, urea, thiourea, magnesium potassium sulfate fertilizer, calcium superphosphate, phosphorite powder, polyacrylamide, sodium polyacrylate, kaolin, borax, lime powder, dicyandiamide, 3,4-dimethylpyrazole phosphate, N-(n-butyl)thiophosphoric triamide, a microbial agent, potassium fulvate, oxalic acid, xylitol residue, citrus residue, bamboo fiber, sodium dodecyl benzene sulfonate, and a microbial fermentation antibacterial agent. According to the present invention, the yield increasing and insect pest prevention slow-release fertilizer has characteristics of reasonable formula and rich nutrition, can improve the stress resistance of rice, can reduce the incidence of rice pests and diseases, can reduce the fertilizer application cost, can effectively improve the ecological environment of farmlands, can significant improve the yield of rice, and can improve the quality of rice, wherein the nutrient release rate in the fertilizer is basically consistent with the fertilizer requirement law of rice.

Description

technical field [0001] The invention relates to the technical field of agricultural chemical fertilizers, in particular to a slow-release fertilizer for midwifery and pest control for rice and a preparation method thereof. Background technique [0002] Rice is an important food crop in my country. It has the characteristics of wide planting area and large demand. It is of great significance to the daily life of residents and my country's grain reserves. In recent years, improving rice production has always been a hot research field. With the large-scale promotion of hybrid rice and super rice, there are problems such as serious diseases and insect pests in the process of rice cultivation, and the yield cannot reach the ideal level. The large amount of pesticides used in the cultivation process will endanger the ecological environment of the farmland, increase the cost of agricultural production, and is not conducive to The sustainable development of agriculture in our countr...

Problems solved by technology

With the large-scale promotion of hybrid rice and super rice, there are problems such as serious diseases and insect pests in the process of rice cultivation, and the yield cannot reach the ideal level. The large amount of pesticides used in the cultivation process will endanger the ecological environment of the farmland, increase the cost of agricultural production, and is not conducive to The sustainable development of agriculture in our country, these seriously limit the cultivation of rice

Therefore, many related products have appeared on the market to solve the above problems, but these products have single functions, and improper use may easily cause negative effects, and the release rate of nutrients in fertilizers is inconsistent with the law of rice fertilizer requirements, and the fertilizer efficiency is low. Poor reversibility, prone to pests and diseases, serious loss of fertilizer nutrients, not only increases the cost of agricultural production, but also increases the environmental load of various nutrients escaping from the farmland ecosystem, affecting human health and the natural environment, while limiting the yield of rice and reducing the yield of rice. Quality is not conducive to the sustainable development of my country's agriculture
