Problems solved by technology

[0005] At present, forage seed priming mostly imitates or draws on the priming methods of flower or vegetable seeds [15-17] Although some effects have been achieved, it is very difficult to apply these methods to production practice due to the common characteristics of high cost, complicated operation, difficulty in promotion, difficulty in large-scale promotion and large-scale processing.
For example, the cost of PEG initiation is relatively high, which is not conducive to the promotion of industrialization

Embodiment 1

[0075] (1) Raw material preparation for the initiator solution: The raw material components mixed according to the mass fraction ratio are as follows:

[0076] KNO 3 : 160mM

[0077] K H 2 PO 4 : 140mM

[0078] Salicylic acid: 0.15mM

[0079] (2) Initiating solution configuration:

[0080] ① Weigh KNO 3 Dissolve in 1000mL water, stir until dissolved, and make a 160mM solution, due to KNO 3 Dust is irritating to the respiratory tract, if a large amount of KNO is inhaled 3 The powder can cause pulmonary edema; it is also highly irritating to the skin and eyes. Repeated skin contact can cause skin dryness, chapping and rashes. Therefore, corresponding protective equipment should be worn during use.

[0081] ② Weigh KH 2 PO 4 Dissolve in 1000mL of the above solution, stir until dissolved, and make KH 2 PO 4 up to 140mM;

[0082] ③Heat the above solution on a heater, weigh salicylic acid at the same time, pour it into the solution, and stir until it dissolves so that t...

[0091] (1) Raw material preparation for the initiator solution: The raw material components mixed according to the mass fraction ratio are as follows:

[0092] KNO 3 : 140mM

[0093] K H 2 PO 4 : 120mM

[0094] Salicylic acid: 0.1mM

[0095] (2) Initiating solution configuration:

[0096] ①Weigh 0.0138g of salicylic acid, measure 5mL of absolute ethanol, pour salicylic acid into absolute ethanol, stir until dissolved,

[0097] ② Weigh KNO 3 14.15g, pour it into 1000mL water, then add the absolute ethanol with salicylic acid dissolved in it, stir until dissolved, because KNO3 dust is irritating to the respiratory tract, if you inhale a large amount of KNO3 3 The powder can cause pulmonary edema; it is also highly irritating to the skin and eyes, and repeated skin contact can cause dry skin, chapped skin and rash. Therefore, corresponding protective equipment should be worn during use.

[0110] Salicylic acid: 0.2mM

[0111] (2) Initiating solution configuration:

[0112] ① Weigh KH 2 PO 4 21.77g, dissolved in 1000mL water, stirred until dissolved,

[0113] ② Weigh KNO 3 18.20g, pour into the above 1000mL water, stir until dissolved, because KNO3 dust is irritating to the respiratory tract, if a large amount of KNO3 is inhaled 3 The powder can cause pulmonary edema; it is also highly irritating to the skin and eyes, and repeated skin contact can cause skin dryness, chapping and rash. Therefore, corresponding protective equipment should be worn during use.

[0114] ③Heat the above solution on a heater, weigh 0.0276g of salicylic acid at the same time, pour it into the solution, stir until it dissolves, and finally obtain the prepared trigger solution...

Abstract

The invention relates to a medicago sativa seed priming solution which comprises the following components in percentage by mass: 140-180mM of KNO3, 120-160mM of KH2PO4 and 0.1-0.2mM of salicylic acid. The preparation and priming method of medicago sativa seed priming solution comprises the following steps: (1) preparing priming solution raw materials; (2) preparing a priming solution; (3) treating the seed priming solution; (4) washing the seeds and removing water; and (5) drying the seeds, namely performing forced air drying at the temperature of 20-25 DEG C for 48 hours, and obtaining the treated seeds. The priming of the medicago sativa seeds is carried out by adopting a proper inorganic salt solution, the activity of the seeds and the stress resistance of seedlings can be effectively improved, and the technology is simple and feasible, low in cost and obvious in priming effect and has high production and application values.

Description

technical field [0001] The invention belongs to the technical field of seed priming in the pasture planting process, and in particular relates to a preparation of alfalfa seed priming liquid and a priming method. Background technique [0002] Alfalfa (Medicago sativa) is also known as alfalfa. Because alfalfa has the advantages of strong adaptability, high yield, and good quality, it is known as the "king of grass" and is the most widely cultivated perennial leguminous forage. However, due to the small size of alfalfa seeds, the germination speed is slow and the germination period is inconsistent, it is difficult to improve the yield and quality of forage seeds; Drought, low temperature, hardening and other adverse conditions at the seedling stage often lead to slow germination and low emergence rate, which has a negative impact on grass production. Therefore, improving alfalfa seed vigor, increasing seed emergence rate, emergence speed and stress resistance of seedlings a...
