苜蓿根瘤菌剂对紫花苜蓿生长影响研究

摘要

通过不同剂量苜蓿根瘤菌接种两种紫花苜蓿试验，比较了接种根瘤菌剂对紫花苜蓿生长的影响。试验结果表明：接种苜蓿根瘤菌剂能够提高紫花苜蓿结瘤数量和根瘤重，促进紫花苜蓿的生长发育，增加苜蓿草的产草量。在所试验的接种剂量中，以每 kg 苜蓿种子接种12mL 根瘤菌剂为最佳接种量。%This paper studied the alfalfa growing effects of alfalfa rhizobium by inoculated different amounts.The experimental results showed that inoculating rhizobium can raise the nodulating amount of alfalfa and the weight of nodulations,promoting the growth of alfalfas and augment the productions of alfalfas.Among the different inoculated amounts,the amount of 12ml is the best inoculated amount.
