连续两年用VA菌根真菌接种大麦,结果表明:加VA菌根的处理比对照,平均增产10.3%。尤其是磷矿粉加VA菌根比单施磷矿粉的增产13.8%,促进大麦对磷的吸收和利用,使物质积累增加,抗性增强。VA菌根被认识已近百年,但生产上尚未应用。近年来,由于化肥、农药的大量施 VA was used to inoculate barley with VA mycorrhizal fungi for two consecutive years. The results showed that the treatment with VA mycorrhizal increased by 10.3% on average. In particular, phosphate rock plus VA mycorrhizal than the phosphate rock alone increased 13.8% yield, promote the absorption and utilization of phosphorus in barley, so that material accumulation increases, the resistance increased. VA mycorrhizal is recognized for nearly a century, but the production has not yet been applied. In recent years, due to a large number of chemical fertilizers, pesticides facilities
