Embodiment approach
[0073] According to a preferred embodiment of the present invention, the selection of the seeds includes three steps of air selection, screening and water selection.
[0074] The inventors have found through research that after three steps of wind selection, screening and water selection, the seeds of T. tanguticum can be effectively improved in terms of clarity, consistency and robustness.
[0075] In a further preferred embodiment, the screening is sieving with a 3mm sieve to remove impurities in the seeds.
[0076] In a further preferred embodiment, the water is selected by adding water to the screened seeds and stirring, and soaking the seeds for a period of time, so as to remove the floating empty seedlings and insect-eaten seeds.
[0077] Preferably, the stirring time is 6-12 minutes, preferably 10 minutes, and the seed soaking time is 3-6 hours, preferably 4-5 hours.
[0078] In the present invention, after the above selection, the seeds with plump, neat, robust and hi...
Embodiment 1
[0136] In the present embodiment, the dormancy of Tanggut white thorn seeds is broken according to the following steps:
[0137] (1) Collection of Tanggut white thorn fruits: From mid to late August to early September, in the wild Tanggut thorn distribution area in the Hexi Corridor of Gansu Province - Pingshan Lake Sandy Land (N 39°06′, Ganzhou District, Zhangye City) E 100°39′), select the mother plant with strong and robust tree vigor, dense fruit, and no pests and diseases as the seed-collecting plant, and collect uniform, plump, and pest-free fruits by picking method;
[0138] (2) The collected fruit is fermented and seeded: the collected fruit is removed from branches, leaves and sundries, put into a wash basin, and water is added to 10:100 according to the mass ratio of water to fruit, fermented at room temperature for 3 days, and the fermentation Put the material into the nylon net loan, rub it repeatedly, rinse the pulp with running water, pour the residue in the nylo...
Embodiment 2
[0146] The method used in this example is the same as that in Example 1, except that step (4) is: soak the selected seeds in 2 mol.L -1 NaOH solution for 50 min.
