Problems solved by technology

However, because it belongs to wild germplasm, the biggest challenge when cultivating it indoors is low seed germination rate, slow growth, and weak plants; if no special treatment is done, its germination rate can only reach 30-50% under normal conditions. It takes 40-50 days to grow to the 4-leaf stage, and the leaves are small and yellow, which is not conducive to scientific research as a research material
[0004] Studies have shown that as a halophytic wild barley, an appropriate amount of NaCl can promote the germination, growth, and photosynthesis of wild barley seeds, but there is no NaCl-based, suitable for rapid indoor germination of wild barley, and enhances the photosynthesis of wild barley seeds. An effective way to grow plants and improve the uniformity of seedlings

Embodiment 1

[0020] A kind of indoor quick cultivation method of wild barley, comprises the steps:

[0021] 1) Remove impurities from wild barley seeds, select uniform seeds and treat them at -20°C for 48 hours, wash wild barley seeds with distilled water, and then use 100mg / L gibberellin to germinate seeds at a low temperature of 0-4°C pre-processing;

[0022] 2) Rinse the pretreated wild barley seeds obtained in step 1) with distilled water, and then spread them evenly on the seed rack of the seed germination box for germination. The nutrient solution in the germination box is a nutrient solution containing 5mmol / L NaCl; The indoor conditions are 24 / 18°C, dark, and the wild barley seeds can germinate after 3 to 5 days, and the germination rate can reach 82%;

[0023] 3) Change the seedlings germinated in step 2) to light culture, 25°C, 16h light and 16°C, 8h no light, alternately, the light intensity is 600μmol / (m 2 s), the culture medium is hydroponics, and the composition is a nutrie...

Embodiment 2

[0028] A kind of wild barley indoor rapid cultivation method, same as embodiment 1 step, just adjusted relevant temperature and NaCl concentration, mainly comprises the following steps:

[0029] 1) Remove impurities from wild barley seeds, select uniform seeds and treat them at -18°C for 48 hours, wash wild barley seeds with distilled water, and then use 150mg / L gibberellin to germinate seeds at a low temperature of 0-4°C pre-processing;

[0030] 2) Rinse the pretreated wild barley seeds obtained in step 1) with distilled water, and then evenly sprinkle them on the seed rack of the seed germination box for germination. The nutrient solution in the germination box is a nutrient solution containing 10mmol / L NaCl; The indoor conditions are 26°C 16h / 16°C 8h, dark, and wild barley seeds can germinate after 3 to 5 days, and the germination rate can reach 85%;

[0031] 3) Change the seedlings germinated in step 2) to light culture, 24°C, 16h light and 15°C, 8h no light, alternately,...

Embodiment 3

[0036] A kind of wild barley indoor rapid cultivation method, same as embodiment 2 steps, just adjusted relevant temperature, time and NaCl concentration, mainly comprises the following steps:

[0037] 1) Remove impurities from wild barley seeds, select uniform seeds and treat them at -16°C for 24 hours, wash wild barley seeds with distilled water, and then use 200mg / L gibberellin to germinate seeds at a low temperature of 0-4°C pre-processing;

[0038] 2) Rinse the pretreated wild barley seeds obtained in step 1) with distilled water, and then spread them evenly on the seed rack of the seed germination box for germination. The nutrient solution in the germination box is a nutrient solution containing 15mmol / L NaCl; The indoor conditions are 20°C for 16h / 16°C for 8h, in the dark, and the wild barley seeds can germinate after 3 to 5 days, and the germination rate can reach 80%;

[0039] 3) Change the seedlings germinated in step 2) to light culture, 24°C, 16h light and 15°C, 8...

Abstract

The invention discloses a hordeum brevisubulatum indoor quick cultivation method. The hordeum brevisubulatum indoor quick cultivation method comprises performing pre-germination treatment on low-temperature-treated hordeum brevisubulatum seeds through gibberellin, washing and then germinating in a nutrient solution containing NaCl, and performing light culture on germinated seedlings inside a hydroponic culture medium; after the germinated seedlings grow for 14-20 days, transplanting uniform seedlings to an earth culture environment; irrigating the seedlings with a doubled nutrient solution containing NaCl, and performing light culture on the seedlings. The hordeum brevisubulatum indoor quick cultivation method has the advantage of solving the problem of low germinating speed, weak plant and slow growth of the wild forage of hordeum brevisubulatum indoors, being capable of rapidly breaking dormancy of the hordeum brevisubulatum seeds and achieving a germination rate of higher than 80% within 3-5 days, obtaining uniform germination, and ensuring that the seedlings grow vigorously in the nutrient solution containing NaCl. The hordeum brevisubulatum indoor quick cultivation method is significant to the aspects such as indoor study of poor biological repeatability of biological characteristics and salt-enduring and drought-resistant performance of the hordeum brevisubulatum to eliminating poor plant growth and low growth speed.

Description

[0001] Technical field [0002] The present invention involves the field of plant planting, and it involves a fast indoor cultivation method of wild wheat. Background technique [0003] Wild Maima ( Hordeum brevisubularum (Trin.) Link) The perennial herbaceous plants belonging to the genus of Hercho. As one of the most salt -resistant salt -resistant plants in the Hercho wheat, they have a close relationship with barley and wheat.It has the characteristics of high yield, good parallelity, and high nutritional value, and has been used as an advantageous species of crop and pasture new varieties.At present, a hybridization experiment has been conducted with pastoral grass, which has cultivated No. 1 wild wheat with high production performance and strong salt resistance.However, because it belongs to the wild species, the biggest challenge when training indoors is the low seed germination rate, slow growth, and weak plants;It takes 40 to 50 days to grow to 4 leaves, and the leaves a...
