摘要
对紫花苜蓿进行接种根瘤菌和施磷肥处理,结果表明:基施磷肥提高了公农1号紫花苜蓿的结瘤率、单株根瘤数、根瘤重和分枝数,增加了干草产量。比较各施磷水平,以施过磷酸钙300kg/hm2效果最好。接种根瘤菌剂结合施磷肥的效果比单施磷肥和单独接种根瘤菌的效果好,各不同处理中以接种根瘤菌3.75kg/hm2配合施过磷酸钙300kg/hm2效果最好。
The effects of inoculation of rhizobium and application of phosphate fertilizer on alfalfa ＂Gongnong No. 1＂were studied. The results showed that basic application of phosphate fertilizer increased nodulation rate, root nodule number and weight per plant, branch number and hay yield of alfalfa ＂Gongnong No. 1＂significantly. The effect of application of 300kg/hm^2 perphosphate fertilizer was the best. The effect of inoculation of rhizobium combined with application of phosphate fertilizer was better than inoculation of rhizobium alone or basic application of phosphate fertilizer alone. Among all treatments, the effect of inoculating rhizobium 3.75kg/hm^2 combined with application of 300kg/hm^2 perphosphate fertilizing was the best.
