Under greenhouse conditions, the effects of soybean inoculation with soybean cyst nematode on the growth of root system, nodules and the absorption of several mineral elements and the amount of transfer were studied.The results showed that 14 nematode Decreased, reduced nodulation activity, and no significant difference with the non-inoculation treatment; the susceptible variety Hefeng 25 total root length decreased, with no significant difference in the non-inoculation treatment Susceptible variety Suinong 14 inoculated nematode P elemental total absorption decreased, And the non-inoculation treatment was significantly different.The susceptible variety Hefeng25 after inoculation nematodes P element from the ground to the ground to reduce the amount of transfer, significant difference with the non inoculation Figure 4 Table 2 Reference 7
