采用完全随机实验设计,对新牧1号杂花苜蓿适宜浇水时期、浇水次数及浇水量进行研究,结果表明:不同浇水处理对提高新牧1号杂花苜蓿干草产量有一定的影响,各试验处理间表现出显著差异(P<0.05);浇水时期中以刈割前5天浇水增产效果最好,干草产量比对照提高25.67%以上,且浇水处理增大了苜蓿干草中茎杆比例;浇水次数可以提高干草品质,且以浇二水处理效果较好,产量比对照提高18.94%以上;浇水量中以1 130 m3/hm2的处理干草产量最高,比对照提高24.92%。
A completely randomized experimental design was used to study the suitable watering period, watering times and watering amount of Sanmu 1 alfalfa. The results showed that different watering treatments had certain effects on improving hay yield of Xinmu 1 alfalfa (P <0.05). In the watering period, the yield was increased by watering five days before cutting, the yield of hay increased more than 25.67% compared with the control, and the watering treatment increased the yield of alfalfa The ratio of stalks in hay; the number of watering can improve the quality of hay, and the treatment with pouring two water is better, the yield is increased by 18.94% or more compared with the control; the yield of hay with the treatment of 1 130 m3 / hm2 is the highest, Increase 24.92%.
