Special carbon-vinegar slow-release biological fertilizer for paddy rice and preparation method thereof

Abstract

The invention discloses a special carbon-vinegar slow-release biological fertilizer for paddy rice and a preparation method thereof. The special carbon-vinegar slow-release biological fertilizer for paddy rice comprises the following components in percentage by weight: 40-50% of urea, 10-15% of diammonium phosphate, 10-20% of potassium chloride, 2-5% of microelement, 20-30% of organic carbon and 8-10% of vinegar. The preparation method comprises the following steps: slow-release granular fertilizer preparation: respectively pulverizing prepared raw material fertilizers and organic carbon, mixing the raw material fertilizers and the organic carbon in a weight ratio of (50-80):(20-50) to obtain raw materials, spraying vinegar which accounts for 1.3-9.8 wt% of each raw material, uniformly mixing, granulating, finishing, and drying to obtain various slow-release granular fertilizers; nutrient analysis: making an analytical inspection report after analyzing the soil nutrients and crop characteristics; and preparation: preparing the target special carbon-vinegar slow-release biological fertilizer for paddy rice according to the component proportioning. The preparation method disclosed by the invention is simple, economic and environment-friendly, lowers the production cost, and enhances the economic benefit.

Description

technical field

[0001] The invention belongs to the field of biotechnology, further belongs to the field of biofertilizer technology, and in particular relates to a rice slow-release biofertilizer and a preparation method thereof. Background technique

[0002] Rice needs to absorb more nutrients in a growth cycle, not just nitrogen, phosphorus, and potassium provided by ordinary fertilizers. According to the theory of short boards of wooden barrels, if there is a lack of other nutrients, it will not be able to grow normally, the plants will be thin and small, and the heading will not be good. Qi, pollination rate is low, seriously affecting yield. At present, due to the significant increase in production of chemical fertilizers and the large-scale use of them, the soil texture is polluted and deteriorated, and the natural ecological conditions are destroyed. In particular, the utilization rate of fertility is low, which not only wastes resources, but also pollutes the envir...
