Dormancy breaking method for nitraria tangutorum
A seed and solution technology, applied in the direction of seed and rhizome treatment, application, cultivation, etc., can solve the problems of difficult to measure the correct results of seeds, hinder the diffusion of germination inhibitors, and the low rate of breaking seed dormancy, so as to improve the field seedling growth rate, increasing the basic seedlings in the field, and uniform emergence of seedlings

Embodiment approach
[0073] According to a preferred embodiment of the present invention, the selection of the seeds includes three steps of wind selection, screening and water selection.
[0074] The inventor found through research that after Nitraria tangutica seeds are subjected to three steps of air selection, screening and water selection, the seed clarity, consistency and robustness can be effectively improved.
[0075] In a further preferred embodiment, the screening is carried out with a 3mm sieve to remove impurities in the seeds.
[0076] In a further preferred embodiment, the water is selected as stirring the screened seeds with water, and soaking the seeds for a period of time to remove floating empty seeds and insect-eaten seeds.
[0077] Preferably, the stirring time is 6-12 minutes, preferably 10 minutes, and the soaking time is 3-6 hours, preferably 4-5 hours.
[0078] In the present invention, through the above-mentioned selection, the seeds that are plump, neat, strong and with ...
Embodiment 1
[0136] In the present embodiment, the dormancy of Nitraria tangutica seeds is broken according to the following steps:
[0137] (1) Collecting the fruits of Nitraria tangutica: From mid-to-late August to early September, in the distribution area of wild Nitraria tangutica in the Hexi Corridor of Gansu Province—Pingshan Lake sandy land in Ganzhou District, Zhangye City (N 39°06′ E 100 ° 39'), select the mother plant with strong tree vigor, dense fruit, and no pests and diseases as the seed collection plant, and collect uniform, plump, and pest-free fruits through the picking method;
[0138] (2) Ferment the collected fruits and take seeds: remove the branches, leaves and sundries from the collected fruits, put them in the washbasin, add water according to the mass ratio of water to fruits at 10:100, and ferment at room temperature for 3 days. Put the stuff into a nylon net, rub it repeatedly, rinse the pulp with running water, pour the residue in the nylon net into the basin,...
Embodiment 2
[0146] The method used in this embodiment is the same as that of Example 1, the difference is only that step (4) is: the seeds of the selected treatment are soaked in 2mol.L -1 in NaOH solution for 50min.
