Abstract
In order to obtain high yield of alfalfa on saline-alkali soil,the effect of seeding rate,fertilizer stage and fertilizer quantity on alfalfa yield was studied on saline-alkali soil with orthogonal design.The results showed that alfalfa yield with seeding rate of 21.05 kg·hm-2was the highest and the hay yield was 80 899.2 kg·hm-2;Vegetative period don,t to apply fertilizers and do it after cradle(B3)had the best effect;the effect of applying N337.5 kg·hm-2P675 kg·hm-2 was the highest,it was 151 476.7 kg·hm-2;So the treatment of seven reached the highest yield of 52 926.75 kg·hm-2,which was significantly higher than other treatments.The contributron rate of the three factors to yield was seeding ratefertilizer amountfertilization period.关键词
