Special charcoal vinegar slow-release bio-fertilizer for eggplant and fruit and preparation method thereof

Abstract

The invention discloses a special carbon-vinegar slow-release biological fertilizer for solanberries and a preparation method thereof. The special carbon-vinegar slow-release biological fertilizer for solanberriess comprises the following components in percentage by weight: 30-35% of urea, 12-18% of diammonium phosphate, 15-20% of potassium sulfate, 8-12% 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 solanberries 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 slow-release biofertilizer of solanaceous fruit and a preparation method thereof. Background technique

[0002] In a growth cycle of eggplant fruit, more nutrients need to be absorbed, not only nitrogen, phosphorus, and potassium provided by ordinary fertilizers. According to the theory of wooden barrel short board, if there is a lack of other nutrients, it will not be able to grow normally, and the plants will be thin and short Uneven, low pollination rate, 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 enviro...
