Special organic compound fertilizer for improving soil and increasing yield of rice and preparation method of special organic compound fertilizer

Abstract

The invention discloses a special organic compound fertilizer for improving soil and increasing yield of rice and a preparation method of the special organic compound fertilizer. The special organic compound fertilizer contains the following raw materials: livestock excrement, rice bran, cottonseed meal, bean pulp, agricultural rare earth, pyrolignucs acid, a fertilizer fermenting agent, a biological function bacteria liquid, inorganic fertilizer compound particles and a film coating liquid. According to the special organic compound fertilizer and the preparation method, an organic fertilizer,an inorganic fertilizer and a pesticide are reasonably compounded and mixed, and the components of the fertilizer are controllably released, so that the effects of high yield, high quality, efficientnutrient utilization, soil improvement and the like of rice are achieved.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a special organic compound fertilizer for soil improvement and rice production and a preparation method thereof. Background technique [0002] Rice is a kind of herbaceous Oryza genus, and it is also the most important and oldest one as food in Oryza genus. Fertilizers and pesticides play a very important role in rice production, and they play a pivotal role in increasing agricultural production. In the process of planting rice, the use of nitrogen, phosphorus and potassium sulfate is often emphasized while the use of organic fertilizers and micro-fertilizers is ignored. In the process of planting rice fields, rice not only absorbs a large amount of nitrogen, phosphorus, potassium and potassium from the soil every year. A certain amount of calcium, magnesium, sulfur, iron and other elements, but also a small amount of chlorine, zinc, manganese, boron, copper, molybdenum and ...

Problems solved by technology

In the process of planting rice, the use of nitrogen, phosphorus and potassium sulfate is often emphasized while the use of organic fertilizers and micro-fertilizers is ignored. In the process of planting rice fields, rice not only absorbs a large amount of nitrogen, phosphorus, potassium and potassium from the soil every year. A certain amount of calcium, magnesium, sulfur, iron and other elements, but also a small amount of chlorine, zinc, manganese, boron, copper, molybdenum and other trace elements, too much or long-term attention to the use of nitrogen, phosphorus and potassium sulfate will cause rice crops to appear Malnutrition, yield reduction and quality decline, coupled with the extensive use of pesticides, lead to the deterioration of the soil properties of cultivated land and serious pollution of the environment, resulting in the failure of the potential of rice production and the efficiency of natural resources such as soil to be fully utilized
