Embodiment 1

[0035] A soil remediation type organic fertilizer of the present embodiment is mainly made from the following raw materials by weight: 70 parts of modified Trichoderma humic acid, 30 parts of potassium fulvic acid, 35 parts of bean curd residue, 15 parts of coffee grounds, 1 part of compound microbial inoculum and 30 parts of decomposed plant straw.

[0036] Wherein, the preparation of the modified Trichoderma humic acid includes: mixing the Trichoderma humic acid and chitosan according to a mass ratio of 1:0.1, heating the temperature to 55° C., and keeping the temperature for 20 minutes, and then dripping the concentration of 0.1 mol / L. The glycidyl trimethyl ammonium chloride aqueous solution was obtained, and after the reaction was kept for 3 hours, the modified Trichoderma humic acid was obtained after filtration and drying. The mass ratio of the glycidyl trimethyl ammonium chloride aqueous solution to the Trichoderma humic acid is 0.05.

Abstract

The invention discloses a soil remediation type organic fertilizer and a preparation method thereof, and belongs to the technical field of soil improvement. The organic fertilizer is mainly prepared from the following raw materials in parts by weight: 70-100 parts of modified trichoderma humic acid, 30-55 parts of potassium fulvate, 35-60 parts of soybean curb residues, 15-25 parts of coffee grounds, 1-5 parts of a compound microbial agent and 30-50 parts of decomposed plant straws. The soil remediation type organic fertilizer integrates pure fermentation organic fertilizer, microbial fertilizer, plant probiotics and soil physical and chemical conditioning, and has the effects of soil remediation and organic fertilizer.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to a soil remediation type organic fertilizer and a preparation method thereof. Background technique [0002] At present, the cultivated land area in China is decreasing due to factors such as land occupation for construction, disaster destruction, ecological abandonment of farmland, and adjustment of agricultural structure. In addition, due to long-term excessive fertilization and unreasonable fertilization, as well as the unorganized discharge of the "three wastes" in industry and agriculture, the quality of cultivated land continues to decline. As the area of ​​agricultural arable land is decreasing year by year and the situation of soil quality (fertility, environment) is becoming more and more serious, the demand for fertilizers that can provide fertility and also perform soil remediation has become more urgent. SUMMARY OF THE INVENTION [0003] The purpose of the p...
