Abstract
The invention relates to a preparation method of a desertification soil conditioner, the soil conditioner in the method is prepared by mixing agricultural and forestry wastes, plant ash, sludge and non-hazardous waste active carbon according to a certain proportion, then the soil conditioner is paved on the surface layer of sand or buried at a certain depth, green plants or crops are planted on a land, and finally watering or drip irrigation is carried out, so that the green plants or the crops can grow well. The soil conditioner has the characteristics of water retention, fertilizer retention, air permeability and hardening resistance. The soil conditioner can fully utilize wastes, has the characteristic of low cost, and has good application prospect in the aspects of desertification soil treatment and ecological environment improvement.
Description
The technical field is as follows:
the invention relates to a preparation method of a desertification soil conditioner, in particular to a method for preparing the desertification soil conditioner by utilizing various wastes.
The background art comprises the following steps:
with global warming, rapid development of economy and increasing demand for improvement of quality of life of people, and large-scale disorderly and over-exploitation of natural resources by human beings, the ecological environment is increasingly and severely damaged. The soil is also affected by climate change and human activities, and along with frequent rainstorm or flood, organic matters in the soil are quickly lost, the fertility is reduced, green plants are reduced, and the crop yield is reduced. The soil desertification is intensified along with the increase of human activities and the aggravation of climate change in recent decades, and the soil desertification control not only needs policy support to reduce excessive reclamation and grazing, but also needs technical measures to change the trend of the soil desertification and improve the performance and the function of the soil.
The desertified soil is characterized by fine and non-porous particles, narrow particle size distribution and single component, and is mainly silicon dioxide. The water and fertilizer can not be preserved, so the condition for plant growth is lacked, and only a few special plants can grow, which further increases the vulnerability of the ecological environment. Therefore, improvements should be made in three ways: firstly, add the material that is rich in hydroxyl, increase the water-retaining capacity of soil, secondly add organic matter, increase soil fertility, thirdly, add porous material and living beings, improve the quick loss that liquid manure retention time reduced liquid manure. The added sludge, plant ash and waste activated carbon can increase the organic matter content of soil, the plant fiber and the waste activated carbon have porous structures, and the surfaces of the substances contain more hydroxyl groups, so that the water and the fertilizer can be preserved. Therefore, the modifier is prepared from the materials with lower cost, improves the performance and the function of soil, can provide better conditions for the growth of plants, is beneficial to improving the yield of green plants and crops, and has good application prospect.
The invention content is as follows:
the invention aims to solve the problems of fine desertification soil particles, narrow particle size distribution, single component, incapability of retaining water and fertilizer, lack of permeability and lack of plant growth conditions through the application of a desertification soil conditioner. The technical scheme adopted by the invention for solving the technical problem is as follows:
the invention relates to a desertification soil conditioner which is prepared by mixing agricultural and forestry wastes, plant ash, sludge and non-hazardous waste activated carbon according to a proportion. The soil conditioner is paved on the surface layer of the sand or is buried at a certain depth, green plants or crops are planted on the land, and finally watering or drip irrigation watering is carried out, so that the green plants or the crops can grow well. The soil conditioner has the characteristics of water retention, fertilizer retention, air permeability and hardening prevention. The soil conditioner can fully utilize wastes, has the characteristic of low cost, and has good application prospect in the aspects of desertification soil treatment and ecological environment improvement. Can generate obvious economic and environmental benefits and has wide application prospect.
The specific implementation mode is as follows:

Weighing 187.5 kg of sludge containing 20% of water, mixing the sludge with crushed particles of agricultural and forestry wastes according to the mass ratio of 15%, adding 150 kg of plant ash according to the mass ratio of 15%, adding 300 kg of waste activated carbon according to the mass ratio of 30%, uniformly stirring and mixing, extruding and forming into particles at room temperature, and naturally drying to obtain a soil conditioner product.
Example 3
Taking 1000 kg of soil conditioner as an example, 200 kg of waste branches are weighed according to the mass ratio of 20% and crushed into 1 cm particles. Weighing 1000 kg of sludge containing 40% of water, mixing the sludge with crushed particles of agricultural and forestry wastes according to the mass ratio of 60%, adding 100 kg of plant ash according to the mass ratio of 10%, adding 100 kg of waste activated carbon according to the mass ratio of 10%, uniformly stirring and mixing, then carrying out extrusion forming at room temperature to obtain granules, and naturally drying to obtain the soil conditioner product.
Example 4
Taking 1000 kg of soil conditioner as an example, 200 kg of soybean straws are weighed according to the mass ratio of 20%, and are crushed to prepare 2 cm-sized particles. Weighing 1333.3 kg of sludge containing 70% of water, mixing the sludge with crushed particles of agricultural and forestry wastes according to the mass ratio of 40%, adding 100 kg of plant ash according to the mass ratio of 10%, adding 300 kg of waste activated carbon according to the mass ratio of 30%, uniformly stirring and mixing, performing extrusion forming at room temperature to form particles, and naturally drying to obtain a soil conditioner product.
Example 5
Taking 1000 kg of soil conditioner as an example, 380 kg of cotton straws are weighed according to the mass ratio of 38% and crushed into particles with the size of 3 cm. 1375 kg of sludge containing 60% of water is weighed and mixed with crushed particles of agricultural and forestry wastes according to the mass ratio of 55%, 50 kg of plant ash is added according to the mass ratio of 5%, 20 kg of waste activated carbon is added according to the mass ratio of 2%, the mixture is stirred and mixed uniformly, then the mixture is extruded and formed into particles at room temperature, and the particles are naturally dried to obtain a soil conditioner product.
