Embodiment 1

[0028] Embodiments of the present invention provide a method for sowing plants in wind-eroded pits for controlling sandy land, which includes the following steps:

[0029] Reeds cut to 50-60cm are planted and sand barriers are set up in a ditch with a depth of 28-32cm. The number of layers of sand barriers is 2 layers, and the size of the sand barriers is 2m×2m=4m. 2 square. Apply basal fertilizer to the area to be sown. The basal fertilizer applied is diamine hydrogen phosphate and urea with a mass ratio of 2.8:1, and the application rate per mu is 13kg. Irrigation devices were installed in the sowing area, and the number of micro-spray belts of the irrigation device was set at 10 per 16 mu, and other settings were carried out as described in S3.

[0030] After the above measures are completed, planting will be carried out from early June to mid-August. The sowing rate is 4kg per mu, the sowing depth is 3-4.5cm, and the row spacing is 35cm. The mass ratio of barley, Caragana ...

[0032] Embodiments of the present invention provide a method for sowing plants in wind-eroded pits for controlling sandy land, which includes the following steps:

[0033] Reeds cut to 50-60cm are planted in a ditch with a depth of 28-32cm to set up a sand barrier. The number of sand barriers is 3 layers, and the size of the sand barrier is 1.5m×1.5m=2.25m 2 square. Apply base fertilizer to the area to be sown. The applied base fertilizer is diamine hydrogen phosphate and urea with a mass ratio of 3.2:1, and the application rate per mu is 15kg. Irrigation devices were installed in the sowing area, and the number of micro-spray belts of the irrigation device was 14 per 16 mu, and other settings were carried out as described in S3.

[0034] After the above measures are completed, planting will be carried out from early June to mid-August. The sowing rate is 6kg per mu, the sowing depth is 3-4.5cm, and the row spacing is 30cm. , Caragana microphylla and wheatgrass mass ratio is...

Embodiment 3

[0036] Embodiments of the present invention provide a method for sowing plants in wind-eroded pits for controlling sandy land, which includes the following steps:

[0037] Reeds cut to 50-60cm are planted in a ditch with a depth of 28-32cm to set up a sand barrier. 2 square. Apply basal fertilizer to the area to be sown. The basal fertilizer applied is diamine hydrogen phosphate and urea with a mass ratio of 3:1, and the application rate per mu is 14kg. Irrigation devices were installed in the sowing area, and the number of micro-spray belts of the irrigation device was 12 per 16 mu, and other settings were carried out as described in S3.

[0038] After the above measures are completed, planting will be carried out from early June to mid-August. The sowing rate is 5kg per mu, the sowing depth is 3-4.5cm, and the row spacing is 32cm. The mass ratio of Caragana microphylla and wheat grass is 1:1:1:1.

Abstract

The invention relates to the technical field of sand land governance, and provides a method for seeding plants in a blowout pit for governing a sand land. The method comprises the following steps thata sand-protecting barrier is arranged at a wind gap; a base fertilizer is applied; a plurality of seeds are mixed uniformly, and then seeding is carried out, the seeding rate is 4-6 kilograms per mu,and the seed combination for seeding includes any one of the following combinations of hedysarum laeve maxim, barley, caragana microphylla and wheatgrass; sea-buckthorn, hedysarum laeve maxim, caragana microphylla, barley, artemisia desterorum spreng, wheatgrass and great white caragana korshinskii; artemisiahaloden-dron, achnatherum splendens, grassland number three alfalfa, caragana microphylla, calamagrostis epigejos, artemisia frigida, leymus, Chinese wildrye, astragalus melilotoides pall, allium senescens, Longmu 806 alfalfa, glycine ussuriensis, saposhnikovia divaricate, elytrigia repens and Mengnong wheatgrass and the like. By adopting the method, after the seeded plants grow to be mature, the vegetational cover area of the blowout pit is large. The invention further provides a sand land governance method comprising the above method for seeding plants in the blowout pit for governing the sand land, so that the sand land can get effective governance.

Description

technical field [0001] The invention relates to the technical field of sandy land control, in particular to a method for sowing plants in wind erosion pits for sandy land control and a sandy land control method. Background technique [0002] At present, some areas in the north are seriously desertified. Taking the Hulun Lake Basin as an example, the Hulun Lake Basin has 33,300 km 2 grassland, accounting for 80.13% of its total area. The grassland ecosystem has important ecological functions such as water and soil conservation, windbreak and sand fixation, and maintenance of biodiversity. At the same time, it provides grassland resources for animal husbandry. According to the analysis of remote sensing images in 2013, the grassland in the Hulun Lake Basin degraded 20,300 km 2 , accounting for 60.73% of the grassland area in the lake area, and the desertified grassland area is 15.53 million mu. The Hulun Lake Basin, coupled with continuous drought and overgrazing along the ...
