摘要
通过在景电灌区北部沙地上引种、种植优质苜蓿 ,使单位面积苜蓿草地的产量、质量高于沙区当地苜蓿 ,也高于当地其它类型的牧草。沙区种植苜蓿要适当增加播种量 ,着重提高保苗率和越冬率 ,加强管理 ,年刈割 3~ 4次 ,可大大提高产量、质量。对改善沙地土壤养分 。
The elite alfalfa variety was introduced and planted in Jintai desert irrigation area. The yield and quality wereincreased obviously than that inlocal alfalfa. It should beincreasing sowing seed amount,improving seedling ratio in seasons, cutting 3~4 times annually and strengthening management. Meanwhile, the nutrition in sand soil wasincreased, salinecontent wasreducedand water saving effectiveness was obvious during the four yearsperiodcultivation.
