A kind of sandy grassland restoration method

Abstract

The invention discloses a method for restoring sandy grassland, belonging to the field of soil restoration. A method for restoring sandy grassland is used for planting saplings. When saplings are planted, the bottom of the saplings can be used as saplings to replace the The root system of the plant absorbs a certain amount of water, effectively making up for the root system of the newly planted sapling that has not yet fully adapted to the planting environment, resulting in the lack of timely water absorption, causing the sapling to dry up or even die, improve the survival rate, and effectively guide the root system of the sapling to store water. The part of the edge of the conical net grows to guide it to attach to the porous attachment fork. Compared with the prior art, it can effectively improve the attachment strength of the root system under the sandy grassland, thereby effectively ensuring that it is subjected to natural phenomena such as wind or rain. , the soil of the desertified grassland is not easy to be lost, and at the same time, it can effectively ensure that the saplings are not easily blown down, effectively maintain the soil-fixing effect of the saplings on the desertified grassland, and significantly improve the restoration effect.

Description

technical field [0001] The invention relates to the field of soil remediation, and more particularly, to a method for remediation of desertified grassland. Background technique [0002] Grassland desertification means that grasslands with sandy surface environments in different climatic zones are affected by wind erosion, water erosion, drought, rodent and insect pests, and improper human economic activities, resulting in varying degrees of damage to natural grasslands, soil erosion, soil desertification, and soil organic matter content. , nutrient loss and grassland productivity decline, resulting in grassland degradation process similar to desert landscape with sandstorm activity as the main feature. [0003] Generally, the soil with soil erosion is relatively loose and the cohesion is not strong. Generally, when soil is fixed by plants, the actual depth of rooting is not enough due to the problem of soil loosening during the rooting process of plants, or it has not yet ta...

AI Technical Summary

Problems solved by technology

[0003] Generally, the soil with water and soil erosion is relatively loose and the cohesion is not strong. Generally, when the soil is consolidated by plants, during the process of rooting the plants, due to the problem of loose soil, the actual rooting depth is not enough, or the roots have not yet taken root in deep areas. Under the action, the soil will be washed away, making it difficult to fix the soil in the part of the soil that is prone to water and soil loss, or the soil fixation effect is poor

[0004] When restoring desertified grassland, plants with more developed root systems are generally planted, and solidification is carried out through their developed root systems, so as to fix the soil and reduce the effect of water and soil loss. However, sandy grassland is generally loose and the cohesion is not strong. In the early stage, the root system is difficult to attach, resulting in a low growth and survival rate of plants, resulting in an insignificant overall restoration effect on the desertified grassland. At the same time, the humidity of the desertified grassland is low, and it is difficult for the roots of the plants to extend downward in time to absorb water. Planted plants are not replenished with water in time, which further leads to low survival rate
