Organic fertilizer for improving heat resistance and lodging resistance of rice

Abstract

The invention discloses an organic fertilizer for improving the heat resistance and the lodging resistance of rice, wherein the organic fertilizer is prepared from the following raw materials by weight: 40-45 parts of active sludge, 13-16 parts of banana peel, 6-8 parts of maifanite powder, 2-3 parts of oxalic acid powder, 2-3 parts of potassium citrate, 3-4 parts of sodium hexametaphosphate, 4-6 parts of calcium phosphate, 41-43 parts of rice straws, 24-28 parts of cinnamomum camphora leaves, 13-16 parts of a 30% hydrogen peroxide solution, 0.9-1.1 parts of tetradecyl trimethyl ammonium chloride, a proper amount of a 5 mol / L sodium hydroxide solution, a proper amount of a 45% ethanol aqueous solution, and a proper amount of water. According to the present invention, the fertilizer has the scientific nutrient ratio; the nitrogen consumption is controlled, the phosphorus content and the potassium content are increased, and the addition of calcium and mineral nutrients is matched, such that the toughness of the rice stem is enhanced, and the breaking resistance of the stem base internode is improved; and with the use of the active sludge, the banana peel and other composted fermentation materials, the soil fertilizer storage space can be expanded, the expansion development of the rice root can be promoted, and the land-gripping ability of the rice is increased so as to enhance the lodging resistance of the rice.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to an organic fertilizer for improving heat resistance and lodging resistance of rice. 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 pro...

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
