The VA mycorrhiza seedlings have been cultivated with different methods by inoculating VAM onto the seedlings in the states of germination and four-leaves.It is shown that the Paper tubles sandy cultural method is fast and economic; otherwise, the Plastic tuble semiwater and Seedling bed-soil methods are slow and expensive, and both of them have few good quality mycorrhizal plants. The VAM inoculation can highly increase plant growth (e.g. plant height, leaf area etc.) and the percentage of seedling survivals in the field under the drought condition.
