Rice base fertilizer prepared from agricultural wastes

Abstract

The invention discloses a rice base fertilizer prepared from agricultural wastes. The rice base fertilizer is an organic fertilizer prepared by taking the agricultural wastes, biogas residues and chicken manure as main raw materials. The method comprises the following steps: crushing the agricultural wastes, adjusting the water content, mixing the crushed agricultural wastes with the biogas residues and the chicken manure, carrying out piling fermentation, carrying out solid-liquid separation, sequentially carrying out sterilization and secondary fermentation on the obtained solid fermentationproduct, mixing the obtained fermentation product with soil in a field, continuously fermenting, and mixing the obtained mixture with urea, calcium carbonate and polyacrylamide to prepare a biological functional fertilizer I; and adding monosaccharide, fishbone dust and a microbial inoculum into the liquid fermentation product, and continuously fermenting to obtain a biological functional fertilizer II. The biological functional fertilizer with two forms can be prepared at the same time, the two fertilizers are matched for use to meet the agricultural requirements of sustainable development,and good application and popularization prospects are achieved.

Description

technical field [0001] The rice fertilizer in the fertilizer preparation technology involved in the present invention is specifically a rice base fertilizer prepared from agricultural waste. Background technique [0002] Rice is one of the main food crops in China. Although its sown area is decreasing year by year, its total output is increasing year by year with the introduction of new varieties. A series of problems such as the destruction of the ecological environment of rice fields. China's cultivated land resources are scarce, and the amount of cultivated land at this stage is declining year by year. It is not realistic to increase the area of ​​rice planted by increasing the area of ​​cultivated land. However, under the traditional fertilization habits of the existing cultivated land, a large amount of inorganic fertilizer is usually used as seed fertilizer for sowing It is applied to the soil at one time without nutrient management. At the same time, due to the sin...

[0002] Rice is one of the main food crops in China. Although its sown area is decreasing year by year, its total output is increasing year by year with the introduction of new varieties. A series of problems such as the destruction of the ecological environment of rice fields

China's cultivated land resources are scarce, and the amount of cultivated land at this stage is declining year by year. It is not realistic to increase the area of ​​rice sown by increasing the area of ​​cultivated land. However, under the traditional fertilization habits of cultivated land, a large amount of inorganic fertilizer is usually used as seed fertilizer for sowing. It is applied to the soil at one time without nutrient management. At the same time, due to the single component of traditional inorganic fertilizers, the utilization rate of components is not high, and the accumulation of dry matter cannot be completed efficiently. At the same time, it will cause a series of problems such as environmental pollution.
