A kind of suspended cultivation method of rubber tree container seedling

Abstract

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.

Description

technical field [0001] The invention relates to a method for raising seedlings of container seedlings, in particular to a method for cultivating container seedlings of rubber trees in suspension. Background technique [0002] The current production and use of rubber tree container seedlings mainly use plastic nutrient bags (generally the size of the nutrient bag is about 15cm×35cm, laid flat) as the container to cultivate the bag seedlings with 2 canopy leaves (including bag seedlings and bag seedlings). The corresponding cultivation method is to place the nutrient bag filled with the culture medium directly on the ground, partially or fully bury it in the soil, and then carry out daily management such as regular watering, fertilization, and weeding after moving the seedlings, until it grows into two canopies with complete leaf canopy ( stable period) out of the nursery. This kind of seedlings often appear curled, entangled, or pierced out of the nutrient bag due to the fac...

AI Technical Summary

Problems solved by technology

This kind of seedlings is often caused by the growth of the seedlings too fast, too long, the size of the nutrient bag is relatively small, and the main root is geotropic, hygrotropic, and light-proof. The nutrition bag is stuck into the ground to form a phenomenon of "piercing the bag", which leads to the shallow or curled taproot of the grown tree, and the plants are not resistant to wind and drought, etc., or it is not conducive to the survival of seedlings, etc.
