Sexual propagation method for trachycarpus fortunei

Abstract

The invention discloses a sexual propagation method for trachycarpus fortunei. The method comprises operation steps as follows: (1) brown and hardened seeds are harvested in the early October every year, air-dried in a shade and put into a jute bag, and agilawood is put into the jute bag; (2) the seeds are taken out in the middle of March in the next year, every 10-20 seeds are put into a small cotton bag, the bag is softly rubbed, then put into a soaking solution to be soaked for 2-3 h at the temperature of 45-50 DEG C and irradiated under ultraviolet light for 40-60 min; then the seeds are put into a ventilated position and spread, and the step is repeated every day until the seeds sprout; (3) a slightly viscous soil land with thick soil layer is selected, subjected to deep ploughing and tedded, 90-110 kg of base fertilizer is applied to each mu, then bedding is performed, drill furrows are dug and sowing is performed. With the adoption of the sexual propagation method for trachycarpus fortunei, the germination rate of trachycarpus fortunei seeds can be effectively increased, the germination speed can be increased, and the emergency uniformity is improved.

Description

technical field [0001] The invention belongs to the field of plant planting, and in particular relates to a palm sexual propagation method. Background technique [0002] Palm is an evergreen tree of the family Palmaceae, up to 7 meters high; the stem is cylindrical, the leaves are nearly round, the petioles are crenate on both sides, the inflorescences are thick, dioecious. Flowers yellow-green, ovoid; fruit broadly reniform, with umbilicus, turning from yellow to light blue when ripe, with white powder, and horny endosperm of seeds. The flowering period is April, and the fruiting period is December. Palm is native to China. Japan, India, and Myanmar also have them. Palm is one of the most cold-resistant palm plants in the world. Except for Tibet, it is distributed in the south of the Qinling Mountains in my country, from the southern part of Shaanxi in the north, to Guangdong, Guangxi and Yunnan in the south, to the border of Tibet in the west, and to Shanghai and Zhejia...

AI Technical Summary

Problems solved by technology

Palm plants mainly use seeds for reproduction, but the seeds are large and have a hard and thick seed shell, resulting in difficult germination after sowing, long germination time, and irregular emergence, which seriously restricts the development of palm planting.
