摘要:
为确定紫花苜蓿种子田的适宜播种密度，以肇东苜蓿品种为试材，设9个不同播种密度处理D1～D9分别为180 000、90 000、84 000、60 000、60 000、42 000、30 000、28 000、20 000株·hm-2，研究密度对紫花苜蓿种子产量的影响。结果表明：在一定范围内，紫花苜蓿种子产量随播种密度的增加而增加，在密度为84 000株·hm-2时，种子产量最高，密度为90 000～180 000株·hm-2时，种子产量反而下降，适宜播种密度60 000～84 000株·hm-2时，紫花苜蓿种子产量较高。
Abstract:
In order to determine the suitable planting density of alfalfa,taking Zhaodong alfalfa variety as material, the effect of 9 different planting densities on yield of alfalfa was studied, which were 180 000、90 000、84 000、60 000、60 000、42 000、30 000、28 000、20 000 plants per hectare. The result showed that in the certain range, the yield of seeds would increase as planting density increasing. The yield of seeds achieved the maximum when density was 84 000 plants per hectare, it would drop when the density was 90 000～180 000 plants per hectare, and it was higher when the optimum density was 60 000～84 000 plants per hectare.
