Problems solved by technology

[0002] Achnatherum splendens is a wild plant that grows widely in deserts, especially in northern deserts. It plays an important role in preventing desertification, protecting and improving the ecological environment, and preventing wind and sand. At the same time, its orange stalk is also a good The raw material for papermaking has important economic value; at present, when propagating Achnatherum splendens by sowing, there are the following problems: in the process of seed germination, it is found that the embryo is not fully developed, and the germination rate is low, generally 30% to 50%. Seriously limit the production of Achnatherum splendens

Embodiment 1

[0013] Embodiment 1: a kind of method that improves Achnatherum splendens seed germination rate, it comprises the following steps:

[0014] (1) Seed selection: select normal and fully mature Achnatherum splendens seeds, and remove foreign seeds, debris, dust and other impurities;

[0015] (2) Seed soaking: mix the selected seeds with a gibberellin solution with a mass concentration of 0.02%, and then place them in an environment with a temperature of 5° C. for 36 hours;

[0016] (3) Cleaning: remove the seeds from the gibberellin solution and rinse them once with water to clean the gibberellin on the seeds; the washed seeds are evenly scattered into a petri dish with a layer of wet filter paper ;

[0017] (4) Cultivation: Put the petri dish into a refrigerator with a temperature of 5° C. to refrigerate for 2 days; then take the petri dish out of the refrigerator and put it into an incubator to accelerate germination. The temperature of the incubator is controlled at 20-30° C....

Embodiment 2

[0019] Embodiment 2: a kind of method that improves Achnatherum splendens seed germination rate, it comprises the following steps:

[0020] (1) Seed selection: select normal and fully mature Achnatherum splendens seeds, and remove foreign seeds, debris, dust and other impurities;

[0021] (2) Seed soaking: the selected seeds are mixed with a gibberellin solution with a mass concentration of 0.07%, and then packed into a ziplock bag, and the ziplock bag is placed in a refrigerator at 10°C for 60 hours;

[0022] (3) Cleaning: Remove the seeds from the gibberellin solution, rinse them with water for 3 times, and clean the gibberellins on the seeds; the washed seeds are evenly scattered into a petri dish with 5 layers of wet filter paper ;

[0023] (4) Cultivation: Put the petri dish into a refrigerator with a temperature of 10°C and refrigerate it for 5 days; then take the petri dish out of the refrigerator and put it into an incubator to accelerate germination, the temperature ...

Embodiment 3

[0025] Embodiment 3: a kind of method that improves Achnatherum splendens seed germination rate, it comprises the following steps:

[0026] (1) Seed selection: select normal and fully mature Achnatherum splendens seeds, and remove foreign seeds, debris, dust and other impurities;

[0027] (2) Seed soaking: mix the selected seeds with a gibberellin solution with a mass concentration of 0.05%, and then pack them into a ziplock bag, and put the ziplock bag into a refrigerator at 7°C for 48 hours;

[0028] (3) Cleaning: Remove the seeds from the gibberellin solution and rinse them twice with water to clean the gibberellin on the seeds; the washed seeds are evenly scattered into a petri dish with 3 layers of wet filter paper ;

[0029] (4) Cultivation: Put the petri dish into a refrigerator with a temperature of 7° C. for 3 days; then take the petri dish out of the refrigerator and put it into an incubator to accelerate germination. The temperature of the incubator is controlled a...

Abstract

The invention discloses a method for increasing the germination rate of achnatherum splendens seeds. The method comprises the following steps of (1) selecting the seeds; (2) soaking the seeds; (3) cleaning the seeds; and (4) culturing the seeds. The method has the beneficial effects that after the seeds are processed by utilizing gibberellin, the seeds are refrigerated, the dormancy of the seeds can be broken, and therefore the germination rate of the achnatherum splendens seeds is increased to 75-85% from the original 30-50%; and the method is simple, economical and insusceptible to the factors such as seasons, climate and natural disasters, by utilizing the process, the problems that the germination rate of the achnatherum splendens seeds is low, and the germination time is long can be solved, and the method has great significance in the production practice of achnatherum splendens.
