Example Embodiment
[0052] Example 1:
[0053] The 148th Regiment of the Eighth Division of the Xinjiang Production and Construction Corps applied the present invention to a shallow-buried drip irrigation alfalfa protected sowing cultivation method in arid areas. The Xinjiang large-leaf alfalfa with autumn dormancy level 4 was selected for the cultivation of alfalfa, and the output of alfalfa was average. It can reach 1100~1400kg / mu, which can increase the yield by 300kg / mu per year compared with flood irrigation.
Example Embodiment
[0054] Example 2:
[0055] The 5th Regiment of the First Division of the Xinjiang Production and Construction Corps applied the present invention to a shallow-buried drip irrigation alfalfa protected sowing cultivation method in arid areas. The WL354 alfalfa with the fall dormancy level 3 to 4 was selected for the cultivation of alfalfa and the yield of alfalfa hay The average increase from 900kg / mu to 1200kg / mu. Observing the production of drip irrigation land and flood irrigation land, it is found that shallow-buried drip irrigation has higher yield and lower water requirement than flood irrigation. Flood irrigation is watered 4 times per year, 120m each time. 3 , 480m throughout the year 3 ; Harvesting 3 crops per year can basically save 30% of water and increase plant height by 3cm. The benefit of using drip irrigation is about 30% higher than that of flood irrigation.
