Pteridophyte seedling raising device

Abstract

The invention discloses a pteridophyte seedling raising device. The pteridophyte seedling raising device comprises a seedling raising basin, a sowing clapboard, and a culture medium pushout constructional element. The seedling raising basin comprises a basin body (2) and a cover body (3) which is matched with the basin body. The basin body is composed of a bottom wall and side walls. Through-holes are formed in the bottom wall. The cover body is composed of a top wall and side walls. Convection holes are formed in the side wall of the cover body. The sowing clapboard (4) is arranged in the basin body and is composed of clapboard side walls and side walls of griddings arranged inside the clapboard side walls. The culture medium pushout constructional element (5) comprises a base seat and a convex circular cylinder which is arranged on the base seat and matched with the shape of gridding cavities. The pteridophyte seedling raising device can improve efficiency of seedling and transplanting, reduce cross infection probability between sporophytes, reduce damage of gametophytes and sporophytes in transplanting process, and has the advantages that cultivating room is made full use of, stability of development environment of spores and seeding transplanting process standardization are guaranteed, management cost is reduced and the pteridophyte seedling raising device is suitable for pteridophyte seedling standardization and large-scale production.

Description

technical field [0001] The invention relates to a fern plant seedling raising device. Background technique [0002] There are 2,456 species of ferns in my country, accounting for 1 / 5 of the total number of ferns in the world, of which 1,218 are endemic. Many ferns have medicinal, edible, ornamental and ecological value. Since fern is a relatively primitive vascular plant, the gametophytic generation (sexual generation) is at a disadvantage, and its growth and fertilization have higher requirements on environmental conditions. Therefore, the cultivation and reproduction of fern is more difficult than that of seed plants, which also greatly restricts The development and utilization of ferns. With people's gradual understanding of the economic value of ferns and the increasing demand for medicinal and edible ferns, it has led to excessive plundering of wild fern resources. Coupled with the deterioration of the environment, the destruction of vegetation, and the decline in hu...

Problems solved by technology

However, the spores of ferns are much smaller than the seeds. If a common seedling device is used in the propagation process, the seedling separation process is difficult to standardize, and it is easy to vary from person to person, thereby affecting production efficiency and increasing the loss of seedlings when transplanting, and the spore germination and Growth and development are very sensitive to changes in environmental conditions, and ordinary seedling raising devices are difficult to meet the requirements
