Method for quickly recovering vegetation of sand-bare plants

[0011] The present invention will be further illustrated below in conjunction with an application example in the Fengning desertification area of ​​Hebei Province.

[0012] On the deserted gentle slopes of Xiaobazi Township, Fengning Manchu Autonomous County, Hebei Province, after the spring gale season and before the rainy season, open a southwest-northeast ditch perpendicular to the main wind northwest wind. The ditch is 20cm deep, 15cm wide, and 30m long. Sprinkle 5g / m water absorbing agent, 40g / m diammonium phosphate, 2g / m mycorrhizal fungus, and cover with 5cm thick sand to form a micro-shaped groove about 10cm deep. The autumn vegetation survey found that the vegetation coverage in the ditch was 83.8%, the average plant height was 17.83cm, and the density was 278 plants / m. 2 , The vegetation coverage of the control bare sand area is 16.3%, the average plant height is 14.39cm, and the density is 82 plants / m 2 . The development and growth of vegetation in the bare sand area us...
