Embodiment 1

[0019] The present invention proposes a method for restoring desertified grassland, comprising the steps of:

[0020] S1: Select a deserted grassland, use a rotary tiller to carry out rotary tillage on the desertified grassland, and the depth of the rotary tillage is 4cm, and then set up sand control nets on the sandy grassland, and the cross-sectional area of ​​the area surrounded by the sand control nets is divided equally by 100 meters, and the height of the anti-sand net is 30cm, which can block the external sand;

[0021] S2: On the desertified grassland treated in S1, evenly spread microbial fertilizer in the area surrounded by sand prevention net, and the water content in the microbial fertilizer must be higher than 20%, and the amount of microbial fertilizer is 250kg / mu. Then use a small rotary tiller to perform rotary tillage on the deserted grassland again. It is necessary to ensure that the microbial fertilizer and the soil are mixed with each other and let it stand...

Embodiment 2

[0032] The present invention proposes a method for restoring desertified grassland, comprising the steps of:

[0033] S1: Select a deserted grassland, use a rotary tiller to perform rotary tillage on the desertified grassland, and the depth of the rotary tillage is 5cm, and then set up sand control nets on the sandy grassland, and the cross-sectional area of ​​the area surrounded by the sand control nets is divided equally by 120 meters, and the height of the anti-sand net is 40cm, which can block the external sand;

[0034] S2: On the sandy grassland treated in S1, evenly spread microbial fertilizer in the area surrounded by sand control nets, and the water content in the microbial fertilizer must be higher than 20%, and the amount of microbial fertilizer is 270kg / mu. Then use a small rotary tiller to perform rotary tillage on the deserted grassland again. It is necessary to ensure that the microbial fertilizer and the soil are mixed with each other and let it stand for 8 day...

Embodiment 3

[0045] The present invention proposes a method for restoring desertified grassland, comprising the steps of:

[0046]S1: Select a deserted grassland, use a rotary tiller to carry out rotary tillage on the desertified grassland, and the depth of the rotary tillage is 6cm, and then set up sand control nets on the sandy grassland, and the cross-sectional area of ​​the area surrounded by the sand control nets is 140 meters, and the height of the anti-sand net is 50cm, which can block the external sand;

[0047] S2: On the sandy grassland treated in S1, spread microbial fertilizer evenly in the area surrounded by sand control nets, and the water content in the microbial fertilizer must be higher than 20%, and the amount of microbial fertilizer is 290kg / mu. Then use a small rotary tiller to perform rotary tillage on the deserted grassland again. It is necessary to ensure that the microbial fertilizer and the soil are mixed with each other and let it stand for 9 days;

Abstract

The invention discloses a restoration method for desertification grassland. The method comprises the following steps that a rotary cultivator is used for rotary tillage on the desertification grassland, then sand-proof nets are arranged at different areas on the desertification grassland, and microbial fertilizer is evenly sprayed in an area defined by the sand-proof nets; the small-sized rotary cultivator is used for rotary tillage on the desertification grassland again, treated grass seeds are evenly sprayed on the desertification grassland, the application amount of grass seeds is 30-50 kg/mu, and a mixture of water and a nutrient solution is evenly sprayed on the grassland; the small-sized rotary cultivator is used for rotary tillage on the desertification grassland, and soil needs tocover the grass seeds. According to the restoration method, by treating the desertification area, the effect on restoration of the desertification grassland is achieved, and accordingly restoration ofthe desertification soil can be achieved.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a method for restoring desertified grassland. Background technique [0002] Grassland is the ecosystem type with the largest land area in my country, with a total area of ​​about 400 million hectares. Since the last century, under the superimposed influence of various factors such as global climate change and human disturbance, my country's grassland has experienced obvious degradation and desertification, which directly or indirectly threatens the survival and life of human beings. According to statistics, about 90% of the available natural grasslands in the country have been degraded to varying degrees. The degraded grassland area accounts for 85.4% of the total grassland area, the desertification area accounts for 35.6%, and the potential desertification area accounts for 46.7%. At the end of the 20th century, the direct economic loss caused by desertification i...
