Problems solved by technology

[0003] At present, most of the prevention and treatment of rice seedling freezing injury is through the application of chemical fertilizers, or by planting cold-resistant varieties, coating agent seeds to solve the freezing injury at seedling stage, but the effect of these methods is sometimes not ideal, and some can be improved by strengthening field water and fertilizer. Management and other prevention, the effect is average and troublesome

Abstract

The invention discloses microbial fertilizer for rice. The microbial fertilizer comprises the following components in percentage by weight: 20%-30% of microbial bacteria, 10%-20% of diatomite, 15%-20% of an assistant and 20%-28% of soluble starch. The microbial bacteria comprise endophytic bacillus subtilis and endophytic bacillus licheniformis by a weight ratio of 7:1. The invention further discloses a method for preparing the microbial fertilizer. The method comprises cultivation of the microbial bacteria and preparation of the microbial fertilizer. The invention has the advantages that freeze injury of rise in a seedling stage is prevented and treated while nutrition is provided to rice.

Description

technical field [0001] The invention belongs to the technical field of microbial fertilizer for plants, in particular to a microbial fertilizer for rice and its preparation method and application. Background technique [0002] Rice is one of the most important food crops in my country and occupies an important position in the national economy. Its sown area, total output and per unit yield all rank first in food crops, which shows the importance of rice. During the growth period of rice, it is greatly affected by temperature, especially the phenomenon of chilling injury at the seedling stage of rice. Chilling injury at the seedling stage of rice refers to the phenomenon that during the seedling raising period, it is affected by continuous or short-term temperature lower than the normal growth and development of rice seedlings, which makes the growth and development obstacles or even death. Generally speaking, seedlings stop growing when the average daily temperature is lowe...
