Problems solved by technology

[0005] There are many special fertilizers for rice on the market, but most of them are inorganic compound fertilizers or organic-inorganic compound fertilizers, that is, fertilizers that produce nitrogen, phosphorus, potassium or nitrogen, phosphorus, potassium and organic matter in a certain ratio. Fertilizers only provide the nitrogen, phosphorus and potassium nutrients needed by rice, and cannot make rice grow well in low temperature environments.

Abstract

The invention discloses a microbial fertilizer containing bacillus subtilis and relates to the technical field of agriculture. The microbial fertilizer is prepared from organic fertilizer and microorganism bacteria. According to the microbial fertilizer containing bacillus subtilis, the organic fertilizer and the microorganism bacteria serve as composition ingredients, so that the growing environment of crops is greatly improved, nutritive substances needed by growth of the crops are provided, the environment adapting capability of the crops is further improved, and the crops can present a good growing state in cold environments.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a microbial fertilizer containing Bacillus subtilis. Background technique [0002] The low temperature and cold damage in the Northeast cold area is a serious natural disaster in Northeast agricultural production, involving a wide range of areas, including food crops, vegetables, fruit trees and many other economic crops. The annual losses caused by this disaster are huge all over the world. For example, according to the survey of the Chinese Academy of Agricultural Sciences, the cold stress of rice is an important limiting factor affecting its high yield, high quality and low consumption. The annual loss of rice output due to cold damage in China is as high as 3-5 billion kg. [0003] The best way to solve this problem is to effectively increase the water temperature of the rice field in the cold region of Northeast China, promote the development of the root system of rice...
