Organic fertilizer for improving soil water holding capacity and plant heat resistance

Abstract

The invention discloses organic fertilizer for improving soil water holding capacity and plant heat resistance, which is prepared from the following raw materials in parts by mass: 30 to 40 of soybean cake powder, 15 to 25 of fish meal, 2 to 8 of crushed crude perlite, 2 to 5 of ferric sodium ethylene diamine tetraacetate, 3 to 5 of potassium selenite, 2 to 5 of urea, 3 to 4 of carboxymethyl cellulose, 42 to 45 of wheat straw, 31 to 33 of camphor tree leaf, 13 to 16 of hydrogen peroxide solution with a mass ratio of 30 percent, 1.1 to 1.4 of tetradecyl trimethyl ammonium chloride, a proper amount of 5mol / L sodium hydroxide solution, a proper amount of ethanol water with a mass ratio of 45 percent and a proper amount of water. According to the organic fertilizer, by extracting from the camphor tree leaf, active matters therein are transferred into the fertilizer, immobilized nutrients and a camphor tree leaf extract are adsorbed by using a uniform sheet cross-laminated porous structure provided by modifying the rice straw, thus the active matters are indirectly provided to plants, after the active matters are absorbed, the leaf stomatal density of the plants can be increased and stomatal aperture and area can be reduced by osmotic adjustment, absorbed water is effectively kept, excessive evaporation of the water is prevented, and the water resistance of the plants is greatly improved.

Description

technical field [0001] The invention relates to an organic fertilizer for improving soil water holding capacity and plant heat resistance. 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 production sustainable development [0003] Stud...

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
