Embodiment Construction
[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0024] like Figure 1~3 As shown, an anti-mixing device for the germplasm resources of red duckweed in a greenhouse includes an isolation frame 2 formed by interlacing vertical and horizontal isolation plates 1, and several cavities 3 for placing potted plants are formed in the isolation frame. The lower end of the isolation plate 1 on the four walls of the cavity is provided with a drain port 4 . The water outlet 4 is used for discharging excess water in time when spraying water.
[0025] The four corners of the isolation frame 2 are extended with support feet 5 , and the four corners of the isolation frame are also provided with slots 6 which can be matched with the support feet 5 . Multi-layer stacking can be carried out as required to increase the height of the isolation frame. The material of the isolation frame 2 is plexiglas...

The invention provides a greenhouse azolla germplasm resource anti-mix device, which comprises an isolating frame formed by interlacing longitudinal and transverse isolating plates, wherein a plurality of cavities for placing potted plants are formed in the isolating frame. The invention also provides a greenhouse azolla germplasm resource preservation method, which comprises the following steps: (1) placing checked azollas in pot heads filled with soil; (2) placing a cultivation frame in a glass air-conditioned greenhouse and controlling the temperature of the greenhouse to be 20-25 DEG C; (3) placing the greenhouse azolla germplasm resource anti-mix device on the cultivation frame; (4) placing the pot heads, in which the azollas are placed in the step (1), in the cavities of the isolating frame of the anti-mix device; and (5) periodically fertilizing the azollas, adding water and separating the azollas. The isolating device has the advantages of simple structure, rational function and convenience in manufacturing, and the survival rate and the purity for azolla germplasm resource preservation can be greatly improved.
Description
technical field [0001] The invention relates to an anti-mixing device and a preservation method for red duckweed germplasm resources in a greenhouse. Background technique [0002] Hongping, also known as Manjianghong, scientific name Azolla, is a symbiotic aquatic plant with ferns and algae. my country is one of the earliest countries in the world to cultivate and utilize red duckweed. The research and application of Hongping was first concentrated on fertilizer, and then expanded to be used as bait for fish, feed for livestock and poultry, and even medicine. At present, it is mainly used in the aerospace field, water pollution treatment, organic fertilizer production, and agricultural comprehensive three-dimensional ecological model. Since a considerable part of Hongping germplasm resources do not produce reproductive organs or have complete male and female reproductive organs under natural conditions, and the technology of artificially inducing spores has not yet been br...
