Problems solved by technology

Rice is a zinc-sensitive crop and needs to absorb more zinc from the soil, but farmers do not apply zinc fertilizers in most cases, which makes the effectiveness of soil zinc decrease year by year, and there is a risk of insufficient zinc supply potential in paddy soil in many areas

Abstract

The invention discloses a compound microbial fertilizer for rice. The fertilizer is prepared from the following raw materials in parts by weight: 20-32 parts of a microbial inoculant, 5-15 parts of charcoal, 20-30 parts of nitrogen phosphorus and potassium fertilizers, 1-5 parts of trace elements, 3-10 parts of nano titanium dioxide, 5-15 parts of a traditional Chinese medicine composition, 12-20parts of silicon, calcium and magnesium fertilizers and 2-5 parts of wood vinegar liquor. The compound microbial fertilizer for rice disclosed by the invention is reasonably matched according to nutrient demand of rice, so that the physical and chemical properties and the granular structures of soil are improved, the fertilizer retaining and water retaining capacities of a rice field are improved,fast growth of rice root systems is promoted, the transplanting survival rate of rice is improved, growth of weeds and plant diseases and insect pests can be also inhibited, generation of soil-bornediseases is alleviated to the maximum extent, use of pesticides is reduced, the cost is lowered, and sustained development of economy and society is facilitated.

Description

technical field [0001] The invention relates to the technical field of crop fertilizers, in particular to a compound microbial fertilizer for rice. Background technique [0002] At present, the conventional fertilization of rice is mostly based on nitrogen, phosphorus, and potassium fertilizers (especially the application of heavy nitrogen fertilizers), and the application of medium and micro-fertilizers is underestimated, which has brought serious problems of partial application of chemical fertilizers and unbalanced nutrition supply and demand in agricultural production. Can not fully meet the nutrients needed for rice growth. Fertilizer is the material basis for increasing rice production. Fertilizer application, especially the rational application of nitrogen, phosphorus, potassium, zinc, and silicon fertilizers, can greatly increase rice yield. Reasonable fertilization, on the one hand, can coordinate the contradiction between rice growth’s demand for nutrient elements...
