Problems solved by technology

[0007] The technical problem mainly solved by the present invention: aiming at the drawbacks that the current grassland soil layer is very thin, and the structure with large gaps under the soil causes the water to infiltrate quickly after raining, and the water cannot be locked, resulting in the grass not growing luxuriantly. A method for preparing grassland soil moisture-retaining materials. In the method, cow dung, horse dung, and sheep dung are mixed in proportion and added to green grass for fermentation, and then castor cake, rapeseed cake, and wheat bran are added to continue fermentation, and urea, magnesium chloride , diammonium phosphate, potassium sulfate, and copper sulfate are added to the water, then fly ash is added to the solution, mixed and added to the fermenter, then active silica gel solution and quartz powder are added to it, and concentrated sulfuric acid is slowly added until the viscosity rises, Then it is taken out, air-dried, ground, and recently carbonized to obtain biochar. This method uses waste feces to make biochar, which is low in cost. The surface properties of the biochar produced can play a role in water retention, thereby increasing the moisture content of the soil. And the treated biochar is rich in nitrogen, phosphorus, potassium and other elements, which can promote the growth of plants

example 1

[0023] Firstly, pick up 50 parts of cow dung, 30 parts of horse manure, 10 parts of sheep manure, and 10 parts of green grass on the prairie in parts by weight. After mixing, they are added to the fermenter, and water is added to the tank until all The material is soaked in it, stirred and mixed evenly, and then sealed and fermented. The fermentation temperature is kept at 38°C, and the fermentation time is 24h; Cake, rapeseed cake, and wheat bran were added to the tank for mixing, 1% of the total mass of yeast was added thereto, and fermentation was carried out for 4 hours; in parts by weight, 25 parts of urea, 20 parts of magnesium chloride, and 18 parts of phosphoric acid were respectively selected. Add diammonium, 20 parts of potassium sulfate, and 9 parts of copper sulfate into water, stir continuously to make it fully dissolved in water, then add 8 parts of fly ash to the solution, stir evenly, and keep the turbid solution for later use; The turbid liquid obtained joins ...

[0029] Firstly, pick up 50 parts of cow dung, 30 parts of horse manure, 10 parts of sheep manure, and 10 parts of green grass on the prairie in parts by weight. After mixing, they are added to the fermenter, and water is added to the tank until all The material is soaked in it, stirred and mixed evenly, and then sealed and fermented. The fermentation temperature is kept at 45°C, and the fermentation time is 36h; Cake, rapeseed cake, and wheat bran were added to the tank for mixing, 2% of the total mass of yeast was added therein, and fermentation was carried out for 6 hours; in parts by weight, 24 parts of urea, 19 parts of magnesium chloride, and 20 parts of phosphoric acid were respectively selected. Add diammonium, 19 parts of potassium sulfate, and 9 parts of copper sulfate into water, stir constantly to make it fully dissolved in water, then add 9 parts of fly ash to the solution, stir evenly, and keep the turbid solution for subsequent use; The turbid liquid that makes j...

Abstract

The present invention relates to a steppe soil moisture retention enhancing material preparation method, and belongs to the field of moisture retention materials. In the prior art, the current steppe soil layer is thin, the large gap structure under the soil causes the rapid water penetration after raining, and the water can not be locked, such that grass growth is not exuberant. A purpose of the present invention is mainly to solve the technical problem in the prior art. According to the present invention, the steppe soil moisture retention enhancing material preparation method is provided, the waste manure is used to prepare the biochar, the cost is low, the surface performance of the prepared biochar can provide the water retention effect so as to increase the water content of the soil, and the treated biochar is rich in nitrogen, phosphorus, potassium and other elements so as to promote the plant growth.

Description

technical field [0001] The invention relates to a preparation method of a material for enhancing grassland soil moisture retention, and belongs to the field of moisture retention materials. Background technique [0002] Grassland is an important resource for people in pastoral areas. However, due to the long-term and unrestrained use of natural resources by people, grassland resources are becoming increasingly exhausted, grassland wind erosion and degradation are becoming more and more serious, soil erosion is intensified, and the ecological environment is deteriorating, which affects the sustainable development of the national economy. . Soil is the foundation of grassland construction, and the nutrient content of soil is an important factor affecting the grassland environment. The essence of typical grassland degradation and desertification is the result of the gradual wind erosion of the chestnut soil layer. The wind erosion process directly weakens the important factors...
