Accelerating germination and seedling method of Mount Tai mountain ash seeds

Abstract

The invention discloses an accelerating germination and seedling method of Mount Tai mountain ash. The accelerating germination and seedling method of the Mount Tai mountain ash comprises the steps ofseed collection, seed purification, gibberellin treatment and accelerating germination, sowing by a seedling machine, seedling transplanting, shading measures in summer, seedling management, time oftaking away sunshade nets and a management technology in winter. The problems that Mount Tai mountain ash seeds are difficult to germinate under natural conditions in the breeding process of the MountTai mountain ash seeds, the seedling survival rate of seedlings is low in the seedling process, the mortality rate of the Mount Tai mountain ash seeds under high temperature sunburn injury is high, and seedling management lacks of science and technology are solved, a scientific and effective technology method for successfully breeding rare Mount Tai mountain ash seedlings is provided, the problemthat the endangered state of Mount Tai mountain ash caused by lack of artificial breeding technology of the Mount Tai mountain ash is solved, the bottleneck of planting wild and valuable and rare seeds of trees is broken through, and sustainable utilization of wild and valuable and rare wild germplasm resources is realized.

Description

technical field [0001] The invention belongs to the technical field of seedling propagation of rare and endangered tree species, and in particular relates to a seed propagation method of Mount Tai mountain ash. Background technique [0002] Taishan Sorbus is a unique wild rare and endangered tree species in Shandong Province and a unique plant in Mount Tai. It grows on the steep slopes of high mountains at an altitude of 1,200 meters. It has green leaves and white flowers in spring, red leaves and red fruits in autumn, and orange-red fruits hang on the branches in winter. It is of great ornamental value. It is a colorful leaf landscape tree species and soil and water conservation tree species in high-altitude mountainous areas. The fruit can be used as medicine, and the young leaves and fruit are rich in nutrition. It is a good woody feed tree species. Taishan Sorbus was discovered by Professor Li Fazeng of the School of Life Sciences of Shandong Normal University in 1983 w...
