Problems solved by technology

[0003] The above-mentioned raw soil maturation technology has the following problems (1) deepening the plow layer can obviously improve the soil structure and alleviate the effect of hardening, but it cannot improve the nutrient content of the soil; , but the composition is complex, the fertilizer effect changes greatly, it is difficult to grasp the accurate amount of fertilizer, the decomposition is slow, and the amount of application is too large; , The improvement effect on the soil aggregate structure is not obvious, the fertilizer effect is slow, and the planting cycle is long; (4) Applying a large amount of chemical fertilizer can improve soil fertility, but the nutrient is single, does not contain organic matter, and chemical fertilizer alone can only increase the nutrient, and cannot It plays the role of soil maturation, and it is easy to cause soil compaction. Therefore, starting with a certain method to solve the problem of raw soil maturation cannot completely and effectively improve the physical properties of the soil and increase the fertility level.

Embodiment 1

[0021] 1. Preparation of Soil Conditioner

[0022] (1) Prepare 6 groups of fermenting bacteria for use: the first group is Aspergillus niger IFF2208, the second group is Cellomonas chrysogenum ACCC11055, the third group is ash polycystic enzyme, Aspergillus flatus A33.2625, and Aspergillus polycysticum A33 .3944, its mass ratio is 6: 3: 1, the fourth group is Penicillium lavender ACCC30170, Trichoderma ACCC30121, Trichoderma korningen ACCC30167 and Versicolor polypore AS3.48, its mass ratio is 3: 2: 1: 4 , the fifth group is Bacillus subtilis ACCC11061 and ACCC11062, its mass ratio is 3:7, the sixth group is Streptomyces jingyang ACCC40023;

[0023] (2) Mix apple pomace, bran, urea, potassium hydroxide and water in a mass ratio of 74:15:10:1:300 to obtain a mixture;

[0024] (3) adding the first group of fermentation bacteria with 1% of the mass of the mixture to the mixture, and fermenting at 30° C. for 24 hours to obtain a primary fermentation product;

[0025] (4) Then, w...

Embodiment 2

[0030] Same as the step of Example 1, the quality of adding water to the second group, the fourth group, and the sixth group of fermentation bacteria in step (4) is replaced by 3000 times to 4000 times, and the fermentation temperature is replaced by 32 ° C, step (5 ) in the third group, the quality of adding water to the fermenting bacteria of the fifth group is replaced by 9000 times by 8000 times.

[0031] At the same time, the step (7) soil conditioner mother liquor, amino acid, citric acid, polyacrylamide, humic acid, urea, ammonium dihydrogen phosphate, and potassium chloride are replaced by 50:10:0.7:2.9:10:10 in mass ratio : 5: 5 is fully chelated to obtain a soil conditioner.

Embodiment 3

[0033] Identical to the steps of Example 1, the quality of adding water to the second group, the fourth group, and the sixth group of fermentation bacteria in step (4) is replaced by 3000 times to 5000 times, and the fermentation temperature is replaced by 35 ° C. Step (5 ) in the third group and the fifth group of fermentation bacteria to add the quality of water by 8000 times to 10000 times.

[0034] At the same time, the step (7) soil conditioner mother liquor, amino acid, citric acid, polyacrylamide, humic acid, urea, ammonium dihydrogen phosphate, and potassium chloride are replaced by 65:5:0.5:2.5:5:12 in mass ratio : 6: 7 is fully chelated to obtain a soil conditioner.

Abstract

The invention relates to a humic-acid soil conditioner and a preparation method thereof. The soil conditioner disclosed by the invention is composed of soil conditioner mother liquor, amino acid, citric acid, polyacrylamide, humic acid, urea, ammonium dihydrogen phosphate and potassium chloride in a mass ratio of (50-65): (3-10): (0.3-1.5): (2.3-2.9): (3-10): (5-13): (5-6): (5-7). The soil conditioner disclosed by the invention can effectively increase the organic matter and nutrient contents of a newly-built farmland, loosen hardened soil, speed up the maturation process of immature soil, and improve or restore the productivity of lands.

Description

technical field [0001] The invention relates to the technical field of farmland raw soil maturation, in particular to a humic acid soil conditioner and a preparation method thereof. Background technique [0002] At present, in order to ensure food production and increase farmers' income to solve the three rural issues, newly repairing farmland is a very important measure. So that the soil structure and soil fertility of the plow layer of the newly repaired farmland will not affect the growth of crops, the raw soil must be matured. At present, the following methods are mainly used for raw soil maturation: (1) adopting the cultivation measures such as harrowing, grinding and pressing mainly for deep plowing; (2) fertilizing with green manure; (3) improving soil and fertilizing by adding organic materials; (4) Improving soil with alien soil, adopting the method of replacing surface soil and mixing alien soil; (5) Intercropping, crop rotation; 6) Applying soil improver to ripen ...
