Embodiment 1
[0042] A method for breaking dormancy of X. sorbifolium seeds of the present embodiment, according to the following method steps, the dormancy of X. sorbifolium seeds is broken:
[0043] (1) Collection of sorbifolium sorbifolium fruit: From mid-early August to early September, in the Hexi Corridor of Gansu Province, Hongshawo forest farm sorbifolium sorbifolium seed collection nursery, select the mother plant with strong tree vigor, dense fruit, and no pests and diseases. Seed-picking plants, through the picking method, collect uniform, plump, and pest-free fruits;
[0044] (2) Seed-taking process: dry the collected Xanthos sorbifolium capsules in a ventilated and dry place, and mechanically remove exocarp and impurities;
[0045] (3) Seed selection treatment: screen the clean seeds with a 5.3mm sieve, remove small, thin, and diseased seeds, then put the seeds into a water basin, add water and stir for 10 minutes, remove empty and insect-eaten seeds, and select full , Neat, r...
Embodiment 2
[0051] In the present embodiment, a method for breaking dormancy of X. sorbifolium seeds, the sample is from a seed batch in Inner Mongolia, and the steps are the same as in Example 1.
[0052] However, implement step 4 seed high temperature treatment: treat the selected seeds in step 3 at 40°C for 72 hours to complete post-ripening of the seeds and improve vigor;
[0053] Implement step 5 to improve the germination port air permeability treatment: the seeds after the high temperature treatment are treated with 5% H 2 o 2 Soak in the solution for 2 hours;
[0054] Implement step 6 seed low-temperature stratification treatment: stratification treatment includes the following steps: ① Clean the river sand and pass it through a 0.05-0.8mm sieve, then disinfect it at 140-145°C for 2 hours, mix water and disinfection sand at a ratio of 1:15 (V / W) Mix evenly and let stand for 1 hour; ② Mix the seeds treated in step ① with step (5) at a ratio of 10:1 (v / v), put them in a wooden box...
Embodiment 3
[0057] In this embodiment, a method for breaking dormancy of radix sorbifolium seeds, the batches of seeds are from the radix radix radix radicis base of the Qilian Mountain Water Source Conservation Forest Research Institute in Zhangye City, Gansu Province, and the steps are the same as in Example 1.
[0058] But, implement step 5 to improve the air permeability treatment of the germination port: the seeds after the high temperature treatment are treated with 0.2% KNO 3 Soak in solution for 30 hours;
[0059] Implement step 6 low-temperature stratification treatment of seeds: stratification treatment includes the following steps: ① Clean the river sand and pass it through a 0.05-0.8mm sieve, then disinfect it at 140-145°C for 2 hours, mix water and disinfection sand at a ratio of 1:13 (V / W) Mix evenly and let stand for 1 hour; ② Mix ① with the seeds treated in step (5) at a ratio of 5:1 (v / v), put them in a wooden box, and store them in a dark vegetable refrigerator at 2-5°C ...
