Biofertilizer capable of enhancing stress tolerance and heat tolerance of plants

Abstract

The invention discloses a biofertilizer capable of enhancing stress tolerance and heat tolerance of plants. The biofertilizer is prepared from the following raw materials in parts by weight: 34-36 parts of traditional Chinese medicine residue, 2-3 parts of EM (effective microorganism) microbial inoculant, 25-26 parts of coconut cream powder, 4-5 parts of talcum powder, 3-4 parts of sodium alginate, 2-3 parts of calcium formate, 4-6 parts of ammonium nitrate, 39-41 parts of rice straw, 34-35 parts of camphor leaf, 13-16 parts of 30% hydrogen peroxide solution, 1.5-1.8 parts of tetradecyltrimethylammonium chloride, a right amount of 5 mol / L sodium hydroxide solution, a right amount of 45% ethanol water solution and a right amount of water. The fertilizer implements effective combination of inorganic nutrients, organic matters and microbial inoculants; the coating form of the nutrient solution can ensure the quantity and activity of the microbial florae in the fertilizer granules; the added traditional Chinese medicine residue and other antibacterial raw materials can well improve the flora structure and physicochemical characters of the soil, enhance the stress tolerance of plants and reduce the disease incidence, thereby enhancing the yield and quality of the plants.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a biological fertilizer for improving stress resistance and heat resistance of plants. Background technique [0002] In agricultural and forestry production, chemical fertilizers are often used in large quantities in order to increase production, resulting in various environmental pollution and soil degradation problems. Bio-organic fertilizers are green and efficient fertilizers because they do not damage the environment and soil. Plant cultivation has been rapidly developed and widely used. However, in the existing technologies related to bio-organic fertilizers, the research on them mainly focuses on how to improve the content and utilization rate of nutrient elements in the soil, and there is no in-depth exploration on the combination of adverse environmental stress and other added values. Fundamentally solve the problem of increasing plant yield and making agricultural ...

However, in the existing technologies related to bio-organic fertilizers, the research on them mainly focuses on how to improve the content and utilization rate of nutrient elements in the soil, and there is no in-depth exploration on the combination of adverse environmental stress and other added values. Fundamentally solve the problem of increasing plant yield and making agricultural production sustainable development

[0003] Studies have shown that under high temperature conditions, plants will cause the accumulation of reactive oxygen species, damage biofilm, destroy chloroplast and other structures, resulting in a decrease in chlorophyll mass fraction, and high temperature will make the intermediate products of plant chlorophyll biosynthesis aminolevulinic acid and protoporphyrin IX The biosynthesis of chlorophyll is affected, which reduces the amount of chlorophyll produced. At the same time, it also leads to increased cell membrane permeability, increased molar concentration of malondialdehyde, electrolyte extravasation, and changes in the anatomical structure of leaves, which in turn affects the growth and development of plants. Affects the accumulation of biomass
