摘  要：
研究了接种菌根菌(Glomus Intraradics)和/或根瘤菌(Bradyrhizobium Japonicum)对紫花苜蓿(Alfalfa)的生长及N、P的吸收效果。试验设4个处理[对照(CK);接种菌根菌(M);接种根瘤菌(R)及同时接种菌根菌和根瘤菌(M+R)],样品的分析是在紫花苜蓿的生长初期(播种后60 d)和开花初期(播种后120 d)分2次进行。随着作物的生长,在各处理区土壤总N量减少了,其中,M和M+R区的减少量相对比CK和R区显著,但作物的生长效果明显优于CK。在第120天进行的土壤有效P含量的分析中,M(65.5 mg/kg)和M+R(62.3mg/kg)区显著高于CK(39.1 mg/kg),而R(42.6 mg/kg)区没有明显变化。此时,在CK中作物的总N、P的吸收量分别为32.1和2.39mg/株,M、R和M+R区总N的吸收量比CK分别高20%、49%和50%,总P的吸收量比CK分别高28%、11%和45%。结果表明,接种菌根菌和/或根瘤菌显著提高作物吸收利用土壤中N、P的能力,以至提高其产量和质量。

摘  要：
To investigate the effect of Mycorrhlza(G.Intraradics) and/or Rhizobium(B.Japonicum)on N and P utilization and the growth of Alfalfa(Medicago sativa L.),four treatments(Non-inoculation,control(CK);Mycorrhiza inoculation,M;Rhizobium inoculation,R and Mycorrhiza and Rhizobium inoculation,M+R) were applied.The analyses of the early vegetative growth stage(DAS 60,60 days after seeding) and on the early flowering stage(DAS 120,120 days after seeding) were carried out.The decreased rate of total N and P content in soil was relatively higher in the mycorrhiza and/or rhizobium treatments than CK,with plant growth.The content of available phosphorus in soil at DAS 120 increased in M(65.5 mg/kg) and M+R(62.3(mg/kg))treatment compared to CK(39.1 mg/kg),while non-significant changes was observed in R(42.6 mg/kg) treatment.Total N and P uptake in CK at DAS 120 were 32.1 mg/plant and 2.39 mg/plant,respectively,about 20%,49% and 50% of increases in total N uptake and 28%,11% and 45% of increases in total P uptake were estimated in M,R and M+R treatment.The present data indicated that mycorrhiza and/or rhizobium inoculation improved N and P utilization,and consequently increased the yield of alfalfa.
