Embodiment 1

[0050] Example 1. A low-density water-retaining insect-resistant saline-alkali soil improver, characterized in that: the density of the low-density organic fertilizer is 0.7g / cm 3 ;

[0051] The organic fertilizer contains: 0.5% of medium and micronutrient elements, 2% of fly ash, 1% of ammonium sulfate, 0.1% of ferrous sulfate, 0.1% of ferric diamine fulvic acid, 1% of immobilized Beauveria bassiana culture, Immobilized Metarhizium anisopliae culture 1%, chelating agent 0.2%, nitrification inhibitor 0.05%, aluminum sulfate 0.15%, and the rest is fermented organic matter;

[0052] The fermented organic matter is to adjust the water content to 40% by adding mushroom slag to crushed straw, and after high-temperature stacking and fermentation with immobilized white-rot fungus culture, add bentonite with a mass percentage of 3% fermented organic matter, and then combine with saline-alkali-resistant compound microorganisms The product after stacking and fermentation of bacterial ...

Embodiment 2

[0075] Example 2. A low-density water-retaining insect-resistant saline-alkali soil improver, characterized in that: the density of the low-density organic fertilizer is 1.0g / cm 3 ;

[0076] The organic fertilizer contains: 1% of medium and micronutrient elements, 5% of fly ash, 1.8% of ammonium sulfate, 0.15% of ferrous sulfate, 0.25% of ferric diamine fulvic acid, 1.5% of immobilized Beauveria bassiana culture, 1.5% of immobilized Metarhizium anisopliae culture, 0.5% of chelating agent, 0.1% of nitrification inhibitor, 0.35% of aluminum sulfate, and the rest is fermented organic matter;

[0077] The fermented organic matter is made by adding mushroom slag to straw pulverized matter to adjust the water content to 45% and stacking and fermenting immobilized white rot fungus culture at high temperature, then adding bentonite with a mass percentage of 8% fermented organic matter, and then compounding with saline-alkali-resistant microorganisms The product after stacking and fe...

Embodiment 3

[0100] Example 3. A low-density water-retaining insect-resistant saline-alkali soil improver, characterized in that: the density of the low-density organic fertilizer is 0.85g / cm 3 ;

[0101] The organic fertilizer contains: 01% of medium and micronutrient elements, 3.5% of fly ash, 1.8% of ammonium sulfate, 0.1% of ferrous sulfate, 0.25% of ferric diamine fulvic acid, 1.5% of immobilized Beauveria bassiana culture, Immobilized Metarhizium anisopliae culture 1.2%, chelating agent 0.5%, nitrification inhibitor 0.1%, aluminum sulfate 0.25%, and the rest is fermented organic matter;

[0102] The fermented organic matter is made by adding mushroom slag to straw pulverized matter to adjust the water content to 40-45% and stacking and fermenting the immobilized white rot fungus culture at high temperature, then adding bentonite with a mass percentage of 3-8% of the fermented organic matter, and then mixing with resistant The product after stacking and fermentation of saline-alkali...

Abstract

The invention discloses a low-density water-retention insect-resistant saline-alkali soil conditioner and a preparation method thereof. The density of a low-density organic bacterial fertilizer is 0.7-1.0 g / cm < 3 >; the organic fertilizer is prepared from 0.5%-1% of medium and trace nutrient elements, 2%-5% of fly ash, 1%-1.8% of ammonium sulfate, 0.1%-0.15% of ferrous sulfate, 0.1%-0.25% of diaminoferric xanthohumate, 1%-1.5% of immobilized beauveria bassiana culture, 1%-1.5% of immobilized metarhizium anisopliae culture, 0.2%-0.5% of a chelating agent, 0.05%-0.1% of a nitrification inhibitor, 0.15%-0.35% of aluminum sulfate and the balance fermented organic matter. The preparation method comprises the steps of mushroom residue treatment, high-temperature fermentation, halotolerant bacteria fermentation, material mixing and the like. The low-density water-retaining insect-resistant saline-alkali soil conditioner has multiple effects of retaining water, inhibiting plant diseases and insect pests, improving the granular structure of saline-alkali soil and the like.

Description

technical field [0001] The invention belongs to the technical field of soil improvement, and in particular relates to a low-density water-retaining insect-resistant saline-alkali soil improver and a preparation method thereof. Background technique [0002] Saline-alkali soil is a general term for saline soil and alkaline soil. Saline soil mainly refers to salinized soil with high chloride or sulfate content. The soil is alkaline, but the pH value is not necessarily high. Alkaline soil refers to the soil containing carbonate or heavy phosphate, the pH value is high, the soil is alkaline, the content of organic matter in saline-alkali soil is small, the soil fertility is low, the physical and chemical properties are poor, especially the hardening is serious. There are many anions and cations that are harmful to crops, and it is difficult for crops to promote seedlings. The principle of fertilization in saline-alkali soil is mainly to apply organic fertilizers and high-effici...
