Problems solved by technology

[0003] 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
At the same time, during the growth of rice, it is extremely vulnerable to the invasion of diseases and insect pests. In order to reduce or eliminate the impact of diseases and insect pests on rice, various pesticides are used during the planting and growth stages of rice, which will not only bring soil, water and Air pollution, and pesticides will be absorbed by crops, resulting in pesticide residues in agricultural products, which seriously threaten human life and health

Abstract

The invention discloses a special compound microbial fertilizer for rice. The fertilizer is prepared from the following raw materials in parts by weight: 20-32 parts of a microbial agent, 5-15 parts of charcoal, 20-30 parts of a nitrogen phosphorus potassium fertilizer, 1-5 parts of trace elements, 3-10 parts of nano-titanium dioxide, 5-15 parts of traditional Chinese medicine composition, 12-20 parts of a silicon-calcium-magnesium fertilizer and 2-5 parts of bamboo vinegar. The compound microbial fertilizer is reasonably prepared according to nutritional requirement of rice, can be used for improving the physical and chemical property and granular structure of soil, improving the fertilizer and moisture retaining capabilities of rice, promoting quick growth of the root system of rice, improving the transplanting survival rate of rice, inhibiting growth of weed, plant diseases and insect pests, reducing occurrence of soil-borne diseases to the furthest extent and reducing use of pesticides, is capable of reducing cost, and facilitates sustainable development of economy and society.

Description

technical field [0001] The invention relates to the technical field of special fertilizer for crops, in particular to a compound microbial fertilizer special 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 f...
