Embodiment 1
[0026] Carry out the cultivation of forage rapeseed Huayouza No. 62 in arid saline-alkali land (pH is 9.0, total salt content 0.91%) in Kashi, Xinjiang: the soil plowing depth is more than 40cm, after plowing, harrow the ground in time to crush the soil and level the land; Rapeseed seeds and superphosphate are mixed uniformly according to the ratio of mass ratio of 1:15, and the drill is used for drilling; the sowing depth is 0.6cm, and the sowing rate is 800g / mu; Flush the capillary and run debug. Drip seedling water within 24 hours after sowing, drip twice in total, and the amount of dripping water is 30m 3 / mu / time, the interval of dripping water is 6 days, when dripping seedling water, the soil salinity improver 2.5kg / mu / time.
[0027] 10 days after the emergence of rape seedlings, start to drip the first water, drip the second water when the leaves are 3 to 4, and squat the seedlings; drip the third water when the leaves are 6 to 7, and apply 5 kg / mu of urea with the wat...
