The invention discloses a container
seedling raising method using
chaff to assist in root
cutting, and belongs to the technical field of container
seedling raising. Aiming at the technical pain points that root systems easily break through containers, seedlings are difficult to take and the
survival rate is low in existing container
seedling raising, the method comprises the steps of laying part of
chaff in a nursery, adding the
chaff into cup filling soil, guiding the root systems to extend in multiple directions by utilizing the chaff after the containers are placed, filling gaps among cups with the chaff and the like, so that the growth of the root systems is physically regulated and controlled. According to the method, more fibrous roots and less main roots can be generated on seedling roots, so that the seedling taking efficiency is remarkably improved (the seedling taking time is shortened by about 30%, and the seedling taking cost is reduced by about 30%), the seedling
survival rate is improved (improved by 3%), and the
transportation cost is reduced (reduced by about 15%). Although the seedling raising cost is increased by 3-5%, comprehensive benefits are remarkable, good
social benefits and
economic benefits are achieved, and the method is suitable for large-scale container seedling raising production of various seedlings such as cedarwood and slash pines; the method has particularly obvious
social benefits and
economic benefits for culturing cup seedlings of
tree species with obvious main roots, such as cyclobalanopsis rubra,
cyclobalanopsis glauca,
liquidambar formosana hance,
phoebe zhennan and the like.
