Embodiment 1
[0042] (1) Site selection
[0043] The relatively flat plots in the Shiyang River Basin were selected as alfalfa planting sites, with good soil structure, rich organic matter, deep soil layers, 0.2% to 0.3% salt content, sufficient water, and a pH value between 7.0 and 8.5.
[0044] (2) Soil preparation
[0045] After the plot is selected, shallow plowing and stubble removal and deep plowing are carried out sequentially in autumn. The depth of shallow plowing is 20cm, and the depth of deep plowing is 30cm. Before the soil freezes, enough winter water is poured, and the irrigation volume is 500m 3 / hm 2 In the spring, after the cultivation layer is dissolved, the processes of applying base fertilizer, spraying herbicides, insecticides, harrowing, compacting, and leveling are carried out in sequence, so that the soil is loosened up and down, so as to facilitate the emergence and growth of seedlings; and remove stones and weeds.
