[0023] A method for promoting rapid germination of Nitraria japonica seeds, comprising the steps of:

[0024] S1. Collect the seeds of Nitraria japonica, remove the pulp on the surface of the seeds, wash them with normal temperature water and dry them, soak them in warm water at 50-60°C for 2 hours, take them out, put them into a polyethylene bag, tie the mouth of the bag tightly, and place them on a flat wooden board. Or gently rub back and forth on the table for 5 times, and plant for 1 hour at 30°C;

[0025] S2. Spread the seeds that have been sown flat on a plate, cover the plate with a wet towel for about 30 minutes, and place it in MnSO4 at a temperature of 30-35°C. 4 + gibberellin + moonshine solution soaked for 40 minutes, fished out, and rinsed with clean water; among them, after soaking for 10 minutes under the condition of 0.06 MPa, immediately return to normal pressure and soak for 30 minutes; MnSO 4 The mass concentration of gibberellin is 0.15g / L, the mass conce...

Abstract

The invention discloses a method for promoting rapid germination of nitraria tangutorum seeds. The method comprises the following steps of collecting the nitraria tangutorum seeds, removing surface pulp, conducting washing and airing, soaking the nitraria tangutorum seeds in warm water, filling the nitraria tangutorum seeds into a polyethylene bag, tightening a bag opening, conducting slight rubbing back and forth on a flat wood plate or tabletop for 5-10 times, conducting seed covering for 1-2 hours at 30 DEG C, paving the seeds in a tray, covering the tray with a wet towel for 30 minutes, putting the seeds into a MnSO4+ gibberellin solution for soaking, fishing out the seeds, washing the seeds with clear water to be clean, pouring the seeds into a culture dish in which double-layer wet filter paper is laid, additionally adding three layers of wet gauzes at the bottom of the culture dish by taking a gauze wrapping the seeds as a first layer, and finally putting the culture dish into an incubator together, and conducting culturing under the temperature changing condition of 17-27 DEG C. By means of the method, the germination rate of the nitraria tangutorum seeds can be remarkablyincreased, the germination rate within 10 days reaches about 81%, germination is tidy, meanwhile, the root system quality of seedlings in the later period can be improved, and the survival rate of theseedlings is increased.

Description

technical field [0001] The invention relates to the technical field of plant planting, in particular to a method for promoting rapid germination of Nitraria thorn seeds. Background technique [0002] Nitraria tangutorum (Nitraria tangutorum) is a medicinal all-parasitic plant, which integrates wind and sand fixation, water and soil conservation, saline-alkali land improvement, pasture and medicinal materials. [0003] The dormancy rate of Nitraria seeds is high. At present, the existing germination methods mainly include: sand storage, warm storage, water soaking and stratification. [0004] For germination in sand storage, first soak the Nitraria seeds in water, mix the sand and seeds in a ratio of 3:1, wrap them in plastic with a mouth, place them in a leeward and sunny place for germination, keep them moist, and turn them up and down frequently. Generally, the seeds will turn white after 30 days. Seeds can be sown after 1 / 3 of the seeds are cracked and exposed, and the e...
