AM真菌与原生动物在花生上双接种效应初探
Preliminary Studies on Effects of Inoculations of AM Fungi and Protozoan on Peanuts
【摘要】 通过AM真菌和原生动物对花生进行双接种 ,研究他们之间的相互作用。结果表明 :双接种比AM真菌单接种降低了AM真菌侵染率 ;比对照增加了植株干物重 ;比对照提高氮、磷吸收量 ,最高可分别提高 12 0 %和 87 7%。原生动物的主要作用在于改善作物氮素营养 ,而AM菌根主要作用在于改善作物磷素营养 ,其协同作用促进了植株的生长及营养状况
【Abstract】 The effects of inoculations of AM and protozoan on peanuts was studied.The results indicated that the infection rate of the treatment which inoculated with both AMF and protozoan was lower than that of AMF,and dry weight and nutrition absorption were increased than the control group.The maximum nitrogen absorption of double inoculations was 12 0% more than the control group,and the maximum phosphorus absorption was 87 7%.The main function of protozoan was to improve N nutrition of plant,but that of AM fungi was to improve plant P nutrition.AM fungi,in cooperation with protozoan,improved growth and nutrition absorption as well.
