Problems solved by technology

[0003] When seeds are subjected to salt stress during germination, the production of active oxygen will be induced, and at the same time, the activity of antioxidant enzymes will be inhibited, resulting in the accumulation of active oxygen that cannot be removed, and then peroxidizes the unsaturated fatty acids on the cell membrane and damages the cell membrane structure , affecting cell membrane function, thereby inhibiting seed germination

Embodiment 1-8

[0070] The impact of salt stress on the germination of the alfalfa pill coat seeds prepared by the ascorbic acid or salicylic acid seed dressing process prepared by the method of embodiment 1 of the present invention

[0071] Using alfalfa seeds as material, use the above method to set different concentrations of ascorbic acid or salicylic acid solutions (Table 4) to carry out pill coating treatment after seed dressing, and control the mass ratio of ascorbic acid to naked alfalfa seeds to be 1.4mg: 1g; The mass ratio of salicylic acid to bare alfalfa seeds was 0.69 mg: 1 g; the salt tolerance performance of the ball-coated seeds with different treatments was evaluated. The NaCl concentration of 1.25% and 1.5% was used as the salt stress concentration of alfalfa, and the control was aqueous solution. Carry out germination test on paper, measure and calculate seed germination potential, germination rate, seedling length, seedling weight, and average germination time.

Abstract

The invention discloses salt-tolerant medicago sativa pelleted seeds and a manufacturing method thereof, belonging to the technical field of seed processing. The salt-tolerant medicago sativa pelletedseeds comprise bare medicago sativa seeds, an adhesive, a powder and an active substance, wherein the active substance is an ascorbic acid solution and / or a salicylic acid solution. The salt-tolerantmedicago sativa pelleted seeds prepared by using the method provided by the invention have the following advantages: the salt stress effect of medicago sativa seeds can be effectively relieved; the vitality of seeds can be improved; a certain germination accelerating effect is achieved; the purposes of promoting seed germination, seedling neatening and seedling strengthening are achieved; meanwhile, the volume and weight of pelleted medicago sativa seeds are increased, and the specifications of the pelleted medicago sativa seeds are uniform, so mechanized and precise seeding of the pelleted medicago sativa seeds can be easily realized.

Description

technical field [0001] The invention belongs to the technical field of seed processing, and in particular relates to a salt-tolerant alfalfa ball-coated seed and a preparation method thereof. Background technique [0002] Alfalfa (Medicago sativa) belongs to the Leguminosae genus Medicagospp. It is a perennial herbage. Because of its good stress resistance, high quality and high yield, it is known as the king of herbage. Alfalfa can improve the soil through biological nitrogen fixation, which not only has high economic value, but also has great value in the protection and restoration of the ecological environment. It plays an important role and is widely planted in saline-alkali land, tidal flats and soil degraded areas for land improvement and grassland restoration. [0003] When seeds are subjected to salt stress during germination, the production of active oxygen will be induced, and at the same time, the activity of antioxidant enzymes will be inhibited, resulting in th...
