Adiantum seedling breeding method based on seed tray spore direct-sowing method

Abstract

The invention discloses an adiantum seedling breeding method based on a seed tray spore direct-sowing method. The method includes the five steps of preparing a substrate, sowing seeds, conducting management after seed sowing, culturing sporephore seedlings, conducting management after dividing and outputting goods. Before seed sowing, insecticides and bactericides are mixed in the substrate first;then, a 200-hole seed tray is filled with the substrate; weight spores are sterilized through alcohol; the sterilized spores are evenly sprayed in the seed tray filled with the substrate; the propertemperature, humidity and luminance are kept for 60 days; after about 60 days, soaking is conducted through borate, and the temperature and luminance intensity are properly reduced and kept for 30 days; then, 30 days later, the temperature and luminance intensity are properly improved, and seedlings are output after growing to meet the specifications. The method has the advantages of saving time and being efficient, high in survival rate and emergence rate, easy to operate, beneficial for large-scale production and the like; the large-scale production of the adiantum seedlings is realized, andthe monopolization of foreign high-price seedlings in the fern type seedling market in China is broken.

Description

technical field [0001] The invention belongs to the technical field of the propagation of fern japonica seedlings, and in particular relates to a method for propagating fern japonica seeds and seedlings based on the method of direct seeding of spores on a plug tray. Background technique [0002] There are more than 2,600 kinds of ferns in my country, of which 500 to 600 are unique to China. It is the country with the largest variety of ferns in the world. my country has a long history of fern planting, but in the true sense of modern large-scale planting of ferns, it is basically It started in the last ten years after 2000. [0003] At present, almost all the best-selling fern species on the market are imported, and the same is true for the fern seedlings. Many domestic units have been actively researching and realizing the localization of the fern seedlings, although certain progress has been made. , but it is difficult to realize the large-scale production of the fern seed...

Problems solved by technology

[0003] At present, almost all the seedlings of the best-selling fern species in the market are imported, as are the seedlings of Adiantum. Many domestic units have been actively researching and realizing the localization of Adiantum seedlings. Although some progress has been made , but it is difficult to achieve large-scale production of Adiantum seedlings. Domestic Adiantum seedlings are still mainly imported seedlings, while the production method of foreign Adiantum is to cultivate the sporophyte seedlings with seedling trays first, and then use The machine divides the cultivated seedlings into 252-hole plug trays, and sells them after the root system grows in the plug trays. However, there is no ramet machine in China, and only manual ramets are available. Due to the limitations of technology and greenhouse environment, the survival rate after ramets The rate is very low, thus limiting the large-scale production of domestic seedlings
