| 摘 要： | 对紫花苜蓿、油菜、碗豆混播植物群落 ,在生长季各类群生物量测定结果表明 :各类群生物量季节动态具有明显的差异 ,其生物量生长速率也各不相同。其中 ,油菜和碗豆生长速率的高峰期在 7月 ,紫花苜蓿在 8月 ,禾草类和杂草类在 6月。试验结果同时说明 ,弃耕地改良后作为刈割和放牧用地 ,苜蓿和其他作物混播不仅有利于当年播种苜蓿在退化盐碱地上的出苗率和保苗率 ,而且可提高人工草地产量 ,增加草地当年收益

| Abstract: | The biomass of Medicago sativa,Brassica campestris, Pisum hypogaea of bled plant community in growth period was steadied The results showed:there is obvious difference among to biomass of each type and growth rate in growth season The summit period of growth rate was the July in Brassica campestris and Pisum hypogaea, the August in Medicago sativa, the June in the Forbes and grass Medicago sativa blended to seed with another corps in the improved wchltvoted land That not only was benefited to the rate of emergence and keeping seedlings but also improved production increased benefit of manmade meadow in same year |
