Abstract

The invention relates to a strong sand fixation and soil conservation agent for repairing degraded ecological environment as well as preparation and application methods of the strong sand fixation and soil conservation agent. The strong sand fixation and soil conservation agent is prepared from the following components including water, crop straw powder, rubber powder, plant seeds, fibers, super-absorbent resin and a compound fertilizer, wherein the weight ratio of the water to the crop straw powder to the rubber powder to the plant seed to the fiber to the super-absorbent resin to the compound fertilizer is (70-90) to (6-14) to (1.5-3.5) to (0.00014-0.0003) to (0.0001-0.0003) to (0.0003-0.0008) to (0.0003-0.0006), preferentially 85 to 12 to 2.5 to 0.00025 to 0.00025 to 0.0005 to 0.0004. According to the preparation and application methods provided by the invention, the prepared strong sand fixation and soil conservation agent is sprayed to the surface of greening ground by virtue of special equipment with a high pressure device and means including crushing, dewatering and mixing, and the plant survival rate is high. Compared with the prior art, the strong sand fixation and soil conservation agent has the advantages of simpleness in process, convenience in spraying operation, cost lower than other synthetic polymers and the like and is an ideal material for ideally controlling desertification and soil and water conservation.

Description

technical field [0001] The invention belongs to a powerful sand-fixing and soil-retaining agent for desertification land and water and soil conservation and control. In particular, it relates to a strong sand-fixing and soil-retaining agent for restoring a degraded ecological environment and a preparation and application method. Background technique [0002] Land desertification is one of the most serious environmental and socio-economic problems in the world and in China today. It is caused by the decline and loss of biological or economic productivity due to the contradiction between man and land, and the surface presents a serious land degradation process similar to desert landscape; while desertification reversal (control ) is the process of coordinating the relationship between man and land, improving the environment, restoring land productivity, and sustaining economic development. For decades, people have worked hard and made unremitting efforts to eradicate desertif...
