摘要
从1988~1990年在兰州馒头山进行了提高鹰嘴紫云英鲜草产量的试验。试验内容是播种量(A)、灌水次数(B)和追肥量(C)的三因素三水平的正交试验。结果表明,最佳组合为A2B3C2,即15kg/hm2的播种量,灌三次水和75kg/hm2的追肥量。
The orthogonal test increasing fresh grass yield of A,cicer was conducted at Mantou Motuntain,Lanzhou from1988 to 1990. The orthogonal test was at three levels and three factors about sowjng norm(A)and irrigation times(B) and fertilizing quantity(C) The result showed that the optimum compositionwas A2B3C2,i.e. sowing norm 15kg/hm2 , irrigating time 3 and fertilizing quantity 75kg/hm2。
