【摘要】 为了探讨不同频次刈割处理对紫花苜蓿产量的影响,试验采用裂区设计方法,测定了不同年度不同刈割频次对"公农1号"苜蓿鲜、干草产量的影响。结果表明:不同年度、不同刈割频次对紫花苜蓿鲜、干产量有极显著影响(P<0.01);2个年度的不同刈割频次间有交互作用,同时刈割频次对不同茬次的草产量也有显著影响(P<0.05)。更多还原

【Abstract】 To investigate the effects of mowing treatments with different frequencies on the yield of alfalfa,a method of split- plot design was used to detect the effects of different years and c different mowing frequencies on the yields of fresh and dry alfalfa named as Gongnong No. 1 alfalfa. The result showed that different years and different frequencies had highly significant effects( P < 0. 01) on the yields of fresh and dry alfalfa. There was some interaction between different mowing frequencies of the two years,and the mowing frequencies also had significant effects( P < 0. 05) on the grass yields of different crop times.更多还原
