Seedling raising method of symplocos paniculata seeds

Abstract

The invention discloses a seedling raising method for symplocos paniculata seeds. The seedling raising method comprises the steps that mature seeds are collected and subjected to stack retting, the mature seeds are scrubbed with clear water after stack retting is completed, the seeds are obtained, liquid obtained after stack retting is collected, filtering and impurity removing are carried out, and stack retting filtrate is obtained; bad seeds are removed, the seeds are soaked in a first solvent at 30-55 DEG C for at least 1 hour, cooling is carried out to a room temperature, soaking is carried out for 5-15 hours, the seeds are fished out and frozen at -5 to -10 DEG C for 10-24 hours, and the seeds are taken out and unfrozen at the room temperature; the unfrozen seeds are put into a second solvent at 45-50 DEG C for being soaked for 0.5-3 hours, are cooled to the room temperature and fished out, then the seeds are frozen at -5 to -10 DEG C for 6-12 hours, and are taken out and unfrozen again; and the seeds unfrozen again are subjected to stratification and refrigeration and then sieved, the sieved seeds are evenly mixed with river sand, the river sand mixed with the seeds is placed at the temperature of 15-30 DEG C for germination accelerating, the seeds subjected to germination accelerating are sieved and sown, and symplocos paniculata seedlings are obtained.

Description

technical field [0001] The application relates to a method for raising seedlings of white sandalwood seeds, which belongs to the technical field of seedling breeding. Background technique [0002] White sandalwood is a deciduous shrub or small tree belonging to the genus of the genus of the genus of the genus, which is widely distributed in the Northeast, North China, and south of the Yangtze River. It is rich in Vc and minerals, its seeds can be used as medicine, and it can grow in a barren environment. It has good economic and ornamental value, and has broad application prospects. [0003] White sandalwood seeds have dormancy characteristics, and the dormancy period is generally 2 years, which is longer. In addition, the germination rate of seeds in the natural state is not high, about 20%. Developed, the survival rate after transplanting is low, and the initial growth rate of seedlings is slow, so the breeding of white sandalwood trees is limited, and the white sandalwoo...
