Spore breeding method for arsenic hyperaccumulator Pteris cretica

The invention discloses a spore breeding method for arsenic hyperaccumulator Pteris cretica. The spore breeding method is implemented and completed by parts, such as a hybrid seedling matrix, a seedling pot, mature Pteris cretica spores and special management and protection and observation. The spore breeding method is capable of, according to the problems that the spore volume of the Pteris cretica spore seedling is small, the seeding rate is hard to be controlled, and the efficiency of forming sporophyte by gametophyte in the natural conditions is low, designing the spore breeding technology, solving the problem that the qualified seedling percentage of the Pteris cretica spore breeding in the natural conditions is low, and designing the complete breeding management technology in allusion to the special requirements of water, illumination and temperature in the breeding period of the Pteris cretica spore, and can be used as a method for breeding the arsenic hyperaccumulator Pteris cretica spores. 本发明公开了种砷超富
