Dangling cultivation method for rubber tree container seedlings

The invention discloses a dangling cultivation method for rubber tree container seedlings. The dangling cultivation method includes the steps: placing a seedling raising container on a support and keeping the seedling raising container in a dangling state, wherein a culture medium is filled in the seedling raising container; transplanting rubber tree seedlings to the seedling raising container and subjecting the rubber tree seedlings to water and fertilizer management till the seedlings grow to two canopies of stable canopies, wherein the seedling raising container is provided with an opening in the bottom. Since main seedling roots are in nearly vertical state, curing and winding are avoided, none or only a few main seedling roots extend out of the bottom of the container, and tips of the main seedling roots are actively kept in the downward growth state; length of the main seedling roots reaches or exceeds relevant national standard requirements. By the dangling cultivation method, field planting survival of the seedlings is benefited, grown plants are developed in the roots which are deeply plunged into the ground, and the plants are high in capabilities of wind resistance, drought resistance and the like.
