Fertilizer-efficiency-controllable biofertilizer capable of improving heating resistance of plants

Abstract

The invention discloses fertilizer-efficiency-controllable biofertilizer capable of improving heating resistance of plants. The biofertilizer is prepared from raw materials in parts by weight as follows: 36-39 parts of sheep manure, 3-4 parts of an EM agent, 18-22 parts of tobacco residues, 3-4 parts of pullulan, 5-6 parts of dolomite calcium powder, 2-3 parts of polyacrylic acid, 3-4 parts of calcium lactate, 4-6 parts of potassium carbonate, 37-38 parts of rice straw, 32-34 parts of leaves of camphor trees, 9-11 parts of a 30% hydrogen peroxide solution, 0.7-1.0 part of n-tetradecyl trimethylammonium chloride, an appropriate quantity of a sodium hydroxide solution with the concentration of 5 mol / L and an appropriate amount of 45% ethanol water and water. The fertilizer has comprehensive nutrients; with addition of the raw materials such as pullulan, polyacrylic acid and the like with good water solubility, the dissolving-out speed of nutritional ingredients in fertilizer particles can be effectively controlled; longer-period nutrient supplementing and releasing of soil can be realized through matching of utilization of multi-type nutrients and addition of decomposed organic matter, and the condition of nutrient loss and waste caused by high probability of too fast nutrient release of conventional fertilizer is avoided, so that the utilization efficiency of the fertilizer is improved.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a biological fertilizer for improving plant heat resistance with controllable fertilizer efficiency. 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...

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
