Embodiment 1
[0027] Embodiments of the present invention provide a method for sowing plants in flat sandy land for controlling sandy land, which includes the following steps:
[0028] 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.
[0029] 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 2-4cm, and the row spacing is 35cm. The mass ratio of seabuckthorn and w...
Embodiment 2
[0031] Embodiments of the present invention provide a method for sowing plants in flat sandy land for controlling sandy land, which includes the following steps:
[0032] 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.
[0033] 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 2-4cm, and the row spacing is 30cm. The mass ratio of seabuckthorn and wheatgrass is 1.2:0...

[0035] Embodiments of the present invention provide a method for sowing plants in flat sandy land for controlling sandy land, which includes the following steps:
[0036] 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.
[0037] 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 2-4cm, and the row spacing is 32cm. The mass ratio of seabuckthorn and ice grass is 1:1:0.5:1.
