All-year cultivation method for drynaria fortunei seedlings

Abstract

The invention provides an all-year cultivation method for drynaria fortunei seedlings. The all-year cultivation method includes the steps of treatment at the earlier stage, seeding, seedling separating and transplanting, field planting, managing after seeding and disease and pest prevention and treatment; the cultivated drynaria fortunei seedlings are high in resistance and wide in application range. During managing after seeding, the conditions of a culturing room are that illumination intensity is 30-50 micromole.m-2.s-1, the illumination period is 14-18 h / d, and temperature is 25+ / -2 DEG C; 50-60 days after seeding, deionized water starts to be sprayed, and 90-100 days after seeding, a 1 / 2 MS solution is sprayed one time every 8-12 days; preferably, the illumination period is 16 h / d, and a 1 / 2 MS solution starts to be sprayed one time every 10 days 90-100 days after seeding. The seedling cultivation technology is suitable for planting production of fields and protected areas. The all-year cultivation method is not limited by seeding seasons; the cultivated seedlings are high in adaptability, and the cultivation method is simple, efficient and easy to popularize.

Description

technical field [0001] The invention belongs to the field of seedling breeding in plant cultivation, and in particular relates to a method for annual breeding of oak fern seedlings. Background technique [0002] Quercus fern is a lower-level higher plant of the genus Quercus fern in the family Quercus fern. It relies on spores for reproduction and can be used for ornamental and medicinal purposes. Usually epiphytic on rocks, creeping or epiphytic on trees, spiral climbing is the mainstream variety of drynaria officinalis, and is a valuable indoor ornamental plant. In my country, it is mainly distributed in Zhejiang, Fujian, Taiwan, Guangdong, Guangxi, Hubei, Sichuan, Guizhou, Yunnan and other places. Due to the cumbersome breeding techniques of live oak fern seedlings and the difficulty of artificial planting and survival, the currently commercially available live oak fern medicinal materials and ornamental plants mainly come from the wild live live live live live live live...

AI Technical Summary

Problems solved by technology

Among them, the propagation of ramets and rhizomes is less used in production due to the limitation of female parent materials, long growth cycle and low efficiency; the cost of tissue culture is high, the equipment required is expensive, and it is difficult to apply and popularize high-level operation techniques; the amount of spore seeding Large size, high emergence rate, simple equipment, and easy-to-master technology are ideal seedling breeding techniques for the promotion and industrial production of Quercus fern, but the current spore seeding technology (spores are seeded on MS medium or pyroclastic soil) 1. Fresh Mature spores, sowing season is limited; 2. Breeding seedlings have poor adaptability and need to imitate the original ecological transplantation (transplanted to trees or rocks)
