Problems solved by technology

During the growth of rice, lodging can lead to a decrease in rice yield
In addition, lodging will increase the manpower and time cost of rice harvesting
An important reason for rice lodging is that the rice root system is poorly developed, and the roots are shallow and unstable, resulting in a lack of support for the plant. In addition, the plant becomes weak due to lack of nutrients

Abstract

The invention discloses a microbial preparation for promoting rooting and lodging resistance of rice and application thereof. The microbial preparation is prepared from glucose, glutamic acid, monocalcium phosphate, sodium borate, zinc sulfate, magnesium sulfate, sodium silicate, compound probiotics and clear water. The raw materials comprise the following components in parts by weight: 50-70 parts of glucose, 2-8 parts of glutamic acid, 20-40 parts of monocalcium phosphate, 2-7 parts of sodium borate, 5-15 parts of zinc sulfate, 2-8 parts of magnesium sulfate, 2-8 parts of sodium silicate, 80-100 parts of compound probiotics and 800-1000 parts of clear water. The microbial preparation is diluted with clear water by 30-50 times, the diluted microbial preparation is sprayed to leaves once in the one-leaf one-core period, the two-leaf one-core period and the middle and later tillering period of the rice growth period, and the use amount of the microbial preparation in the middle and later tillering period is 15-20 L / hm < 2 >. The microbial preparation is sprayed to leaves of rice seedlings, rooting of rice can be promoted, plant stalks are thick and strong, and rice lodging is reduced.

Description

technical field [0001] The invention belongs to the technical field of agricultural microorganisms, and in particular relates to a microbial preparation for promoting rice rooting and lodging resistance and an application thereof. Background technique [0002] Rice is the most important food crop in my country, and the yield of rice is of great significance to people's life and national food security. During rice growth, lodging can lead to reduced rice yield. In addition, lodging will increase labor and time costs when rice is harvested. An important reason for rice lodging is that the rice root system is poorly developed, and the roots are shallow and unstable, resulting in a lack of support for the plant. In addition, the plant becomes weak due to lack of nutrition. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a microbial preparation for promoting rice rooting and lodging resistance and its application, s...
