Rice dry seedling nursery green-up matrix and preparation method of matrix

Abstract

The invention discloses a rice dry seedling nursery green-up matrix which is prepared from the following raw materials: 43% of rice bran powder, 54% of inorganic fertilizer, 3% of conditioning agent and strain. The invention also discloses a preparation method of the matrix, which comprises the following steps: screening the rice bran powder, adding an IBI strain solution, fermenting and crushing into powder; crushing and screening the inorganic fertilizer; uniformly mixing the prepared rice bran strain powder, the inorganic fertilizer and an additive, thus obtaining the matrix. The matrix and the preparation method have the following advantages: 1. the rice bran powder which is rich in nutrient essence of the rice is adopted; 2. a biotechnology is adopted for realizing environmental protection, acid is organically adjusted, and the matrix can resist disease, promote rooting, increase tillering and promote growth; 3. a multi-functional complete nutrition matrix formed by microorganisms, organic nutrients, inorganic fertilizer, medium trace elements and active substances can overcome the defects of a variety of fertilizers and medicaments; 4. 15-20kg of the matrix is used per hectare of the seedling bed to replace a manner that 150-180kg of fertilizer is used in each hectare of the field, so that convenience and quickness are realized, the fertilizer utilization rate is high, the production cost is lowered, and the rice yield can be increased by 10-13.2%.

Description

Technical field [0001] The invention relates to a high-yield cultivation technique for dry-growing rice seedlings and sparse planting, in particular to a rice dry-growing seedlings returning green substrate. Background technique [0002] At present, the rice dry seedling and sparse planting cultivation technology has been fully promoted and applied for many years. However, in the process of rice seedling transplanting, because there is no effective seedbed sending and rejuvenating fertilizer products to promote and use, the application of rejuvenating fertilizer after transplanting has caused problems in the process of rice transplanting. The lack of nutrient supply in the next 5-7 days caused the rice seedlings to turn green and the slow seedling period to be too long, and the effective tillers were delayed, which affected the quality, yield and production efficiency of rice. Summary of the invention [0003] The purpose of the present invention is to provide a substrate for re-g...

Problems solved by technology

[0002] At present, the dry-raised seedling and sparse planting cultivation technology of rice has been fully promoted and applied for many years, but in the process of rice seedling transplanting, because there is no practical and effective seedbed to send green fertilizer products to promote the use, green fertilizer is applied after transplanting, resulting in the process of rice transplanting. The lack of nutrient supply in the next 5-7 days will make the rice seedlings turn green and slow seedling period too long, and the effective tillering will be delayed, thus affecting the quality, yield and production efficiency of rice.
