Wood-vinegar-containing biological compound fertilizer

Abstract

The invention discloses a wood-vinegar-containing biological compound fertilizer. The biological compound fertilizer is mainly prepared from the following raw materials in parts by weight: 10-15 parts of microbial inoculant, 20-30 parts of urea, 5-10 parts of diammonium phosphate, 10-20 parts of potassium chloride, 4-8 parts of calcium magnesia phosphate fertilizer, 10-15 parts of biochar, 1-3 parts of nano titanium dioxide, 0.5-1.5 parts of zinc sulfate, 0.2-1 part of copper sulfate and 2-5 parts of wood vinegar. The biological compound fertilizer is capable of enhancing the utilization ratio of the fertilizer, saving the raw materials and increasing the crop yield, and is also capable of supplying comprehensive nutrients required by crop growth, regulating plant growth and development, killing and resisting bacteria, expelling pests, effectively lowering the disease and pest morbidity and reducing the pesticide use.

Description

technical field [0001] The invention relates to an agricultural biological fertilizer, in particular to a biological compound fertilizer containing wood vinegar. Background technique [0002] At present, the fertilizers used in agriculture are mainly divided into chemical fertilizers and organic fertilizers, but with the improvement of living standards, the cultivation of crops is becoming more and more simple and mechanized. Fertilizers containing one or several nutrient elements needed for the growth of crops, long-term use will easily lead to the destruction of soil structure, reduced production potential, increased metals and toxic elements, reduced microbial activity, difficult conversion and degradation of substances, and nutrient imbalance , Accumulation of nitrate, intensified acidification, too much pH change and other problems. Among the organic fertilizers, most of them are farmyard manures. Although they have many advantages, they have defects such as inconvenie...

Problems solved by technology

[0005] In China, it is not too late to start research on the application of wood vinegar. Since 1989, Yanbian Agricultural College and many other scientific research units have successively started research on the application of wood vinegar, but the actual application started relatively late.
