Organic compound fertilizer for rice

Abstract

The invention relates to organic compound fertilizer for rice. The organic compound fertilizer for rice comprises by weight, 35% to 50% of quail droppings, 8% to 15% of silicon-calcium powder, 8% to 15% of calcium magnesium phosphate fertilizer, 8% to 15% of zeolite ore powder, 8% to 15% of vinasse powder, 4% to 6% of humic acid, 10% to 15% of potassium chloride and 1% to 3% of biological bacterium, wherein the sum of the proportions of all the components is 100%. The method for producing the organic compound fertilizer for rice according to the formula comprises the steps that the quail droppings, the calcium magnesium phosphate fertilizer, the vinasse powder, the humic acid are mixed according to the corresponding proportions, the biological bacterium is added to the mixed raw materials according to the corresponding proportion and evenly stirred, the moisture content is kept to be 50% to 55%, the mixture is accumulated and fermented for 10 days and then is turned, and then the mixture is placed in a turnover plate type fermentation tower to be fermented for 12 days; fermentation is conducted through an aerobiotic fermentation method, and finally the organic compound fertilizer special for rice is obtained. By the adoption of the organic compound fertilizer for rice, the acre yield of rice can be increased, the quality of rice can be greatly improved, grains are full, and the brown rice yield is high.

Description

technical field [0001] The invention belongs to the field of plant fertilizer processing, in particular to an organic compound fertilizer for rice. Background technique [0002] Rice is a food crop that requires the most potassium fertilizer. According to research, for every 100 jin of rice produced, it needs to absorb about 2 jin of nitrogen, 1 jin of phosphorus, and 3 jin of potassium. The ratio of nitrogen, phosphorus and potassium is 2:1:3. But there are some problems in rice fertilization: (1) Too much nitrogen fertilizer and not enough potassium fertilizer. Some farmers are very unscientific in the issue of rice fertilization, often heavy nitrogen and light phosphorus, and do not apply potassium fertilizer. If there is too much nitrogen fertilizer and nutritional imbalance, rice blast is prone to occur, phosphorus-deficient root development is poor, brown rust spots appear on the petiole of potassium-deficient rice, and the amount of roots is small, which affects the ...

Problems solved by technology

However, there are some problems in rice fertilization: (1) too much nitrogen fertilizer and insufficient potassium fertilizer

In terms of rice fertilization, many farmers prefer to use single-nutrient quick-acting fertilizers, such as a large amount of urea, which will cause serious fertilizer loss and reduce nitrogen use efficiency.
