Embodiment 1

[0020] 1 kg of wood bran, 10 kg of peanut cake, 3 kg of lignite, and 0.005 kg of yeast are crushed and added to about 1.5 kg of diluted urea solution (the weight concentration of urea solution is 10%) for mixing, and after mixing, stack and ferment at room temperature for two weeks (or use fermentation equipment to ferment, the fermentation time can be shortened to 24-72 hours), after that, dry it in the air for three days (or dry it with a drying mechanism), and become a dry product of about 10 kg (organic matter ≥ 70%), And carry out secondary pulverization, cross 100 mesh sieves.

[0021] Soak 3 kg of perlite and 4 kg of bentonite in hydrochloric acid with a weight concentration of 10% for 24 hours, add sodium hydroxide solution, adjust the pH to 4-8.5, filter, bake at 120°C to constant weight, mix with organic compost after crushing, and Add 0.04 kg of microbial bacterial agent.

[0022] Adjust the moisture content of the mixed material to 30-45%, fully stir it with a scr...

Embodiment 2

[0024] Put 10 grams of wood bran, 150 grams of bean cake, 35 grams of lignite, and 0.07 grams of yeast. After crushing, add 20 grams of urea solution with a total concentration of 10% for stirring. The time can be shortened to 24-48 hours), and then dried in the air for three days (or dried with a dryer), becoming a dry product of about 140 grams, which is pulverized for the second time and passed through a 100-mesh sieve.

[0025] Soak 40 grams of medical stone and 50 grams of protein soil with hydrochloric acid with a weight concentration of 10% for 24 hours, add sodium hydroxide solution, adjust the pH to 4-8.5, filter, bake at 120°C to constant weight, and compost with organic compost after crushing Mix evenly, add 1 gram of microbial bacterial agent.

[0026] Adjust the moisture content of the mixed material to 30-45%, fully stir it with a screw agitator, and then pile it up for 3-5 days at room temperature, turning it 1-2 times a day. After being decomposed, it is air-d...

Embodiment 3

[0028] Put 25 grams of wood bran, 375 grams of bean cake, 90 grams of peat, and 0.2 grams of yeast. After crushing, add 50 grams of urea solution with a total concentration of 10% for stirring. The time can be shortened to 24-48 hours), and then dried in the air for three days (or dried with a drying machine), and become a dry product with about 340 grams, which is pulverized for the second time and passed through a 100-mesh sieve.

[0029] Soak 90 grams of sepiolite and zeolite mixture and 110 grams of kaolin with hydrochloric acid with a weight concentration of 10% for 24 hours, add sodium hydroxide solution, adjust the pH to 4-8.5, filter, bake at 120°C to constant weight, and compost with organic compost after crushing Mix well, add 3 grams of microbial inoculant.

[0030] Adjust the moisture content of the mixed material to 30-45%, fully stir it with a screw agitator, and then pile it up for 3-5 days at room temperature, turning it 1-2 times a day. After being decomposed...

Abstract

The invention relates to a soil modifier, in particular to a organic compound soil modifier and a preparation thereof, and the compound soil modifier comprises the following raw materials by parts by weight: 100-200 parts of organic matters, 20-40 parts of porous inorganic matters, 30-60 parts of clay, 100-150 parts of strong acid, 60-100 parts of compound fertilizer or urea, 40-70 parts of clay, 0.5-2 parts of microbial agent and 0.03-0.1 part of yeast. The compound soil modifier can significantly improve the soil physical and chemical properties, improve the content of the organic matters in the soil, promote the soil aggregate formation, have a porous structure, effectively prevent the loss of nutrients, promote the crop growth, improve the utilization efficiency of the fertilizer and the like, further utilize the renewable resource, realize small environmental risk and have excellent ecological and economic benefits.

Description

technical field [0001] The invention relates to a soil conditioner, in particular to an organic composite soil conditioner and its preparation. Background technique [0002] In the long-term agricultural production, in order to meet the needs of the increasing population for food production, people use a large amount of arable land irrationally and use chemical fertilizers and pesticides unrestrainedly, which eventually lead to the deterioration of soil physical and chemical properties, nutrient balance imbalance, soil fertility decline, resistance The ability of natural disasters is poor, which seriously affects the normal growth of crops and the increase of yield; at the same time, there is still a serious problem of low fertilizer utilization rate in agricultural production. The deterioration of soil physical and chemical properties has brought about problems such as leaching loss of fertilizer nutrients in the soil. The loss of fertilizer nutrients not only increases the...
