Abstract

The invention discloses a special foliar microbial bacterium fertilizer for paddy rice, and relates to the technical field of microorganism. The microbial fertilizer comprises, by mass, 4-6 parts of potassium fulvate, 2-4 parts of a bacillus agent, 0.1-0.25 part of potassium dihydrogen phosphate, 0.2-0.8 part of potassium sulfate, 0.03-0.08 part of magnesium sulfate, 0.1-0.25 part of diammonium phosphate, and the balance of water; and microbial bacteria of the bacillus agent include Bacillus subtilis and Bacillus methylotrophicus. The invention also provides a preparation method of the specialfoliar microbial bacterium fertilizer for paddy rice. The preparation method of the microbial fertilizer comprises the following steps: preparation of the bacillus agent, and preparation of the microbial fertilizer. The microbial fertilizer provided by the invention is applied to the control process of rice blast, and the strain can be stably colonized in various parts of crops and occupy the ecological niche of the pathogenic bacteria, so the growth of the pathogenic bacteria is inhibited, the growth of the crops is promoted, the yield of the crops is increased, and the product quality is improved.

Description

technical field [0001] The invention relates to the technical field of microbes, in particular to a special foliar microbial fertilizer for rice and a preparation method thereof. Background technique [0002] Microbial bacterial fertilizer is a new type of biological disease-resistant bacterial fertilizer developed by using high-tech biotechnology to solve problems such as the expansion of crop cultivation area, the increase of continuous cropping and the increasing of crop diseases and insect pests. Microbial fertilizer is a live bacterial preparation, which has the advantages of strong activity, many metabolites, good biocontrol effect, safety to humans, livestock, crops and the natural environment, and is not easy to produce drug resistance. It is widely used in the field of economic crop cultivation. [0003] Rice is the main food crop for human beings, and it is also a direct economic crop. The yield and quality of rice are greatly affected by crop diseases and emptines...
