Problems solved by technology

[0003] In the domestic existing technology, PEG osmotic initiation and solid matrix initiation are generally used, and osmotic initiation has the disadvantages of viscous PEG solution and inconvenient cleaning and drying of seeds
The sand and vermiculite solid matrix cause the problem that the matrix is ​​easy to stick to some seeds and not easy to separate
And the existing seed germination method can only process one kind of seed at a time, and the efficiency is low

Embodiment 1

[0036] 1) Weigh 2000g of 'Yanlu' green vegetable seeds, 800g of 'Huqie No. 5' eggplant seeds, and 1200g of 'Leixiao' watermelon seeds and mix them evenly.

[0037] 2) Then pour 4000g of mixed seeds into an aluminum pot with a diameter of 40cm, spray water on the surface of the seed mixture with a sprayer equipped with 1600ml of water, and stir the mixture at the same time.

[0038] 3) Put the aluminum pot into the incubator, set the temperature at 15°C, stir the seed mixture once every 12 hours, cultivate for 72 hours, and then use a belt cleaner to separate the green vegetable seeds from the eggplant and watermelon seeds (the green vegetable seeds absorb water Finally, it is full and round, easy to roll on the inclined belt and can be separated from flat seeds), put the green vegetable seeds in a drying box at 30°C and dry them back to a moisture content of 7% or less, then seal them for storage. Eggplant and watermelon seeds were poured into the aluminum pot and placed in th...

Embodiment 2

[0040] 1) Weigh 2000g of 'Shanglv No. 5' broccoli seeds, 1000g of 'Puhong No. 1' tomato seeds, 1000g of 'Jugua No. 2' mini pumpkin seeds and mix well.

[0041] 2) Then pour 4000g of mixed seeds into an aluminum pot with a diameter of 40cm, spray water on the surface of the seed mixture with a sprayer equipped with 2000ml of water, and stir the mixture at the same time.

[0042] 3) Put the aluminum pot into the incubator, set the temperature at 20°C, stir the seed mixture once every 12 hours, cultivate for 48 hours, and then use a belt cleaner to separate the broccoli seeds from the tomatoes and mini pumpkin seeds. Cauliflower seeds are put into a drying box at 30°C and dried back until the moisture content is below 7%, and then sealed for storage. Continue to pour tomato and mini pumpkin seeds into the aluminum pot and put them into the culture. The temperature is still set at 20°C. After continuing to cultivate for 48 hours, put the seeds in the drying box at 32°C and dry the...

Embodiment 3

[0044] 1) Weigh 3000g of selected cabbage seeds and 1000g of 'Glory' gourd seeds and mix well.

[0045] 2) Then pour 4000g of mixed seeds into an aluminum pot with a diameter of 40cm, spray water on the surface of the seed mixture with a sprayer equipped with 2400ml of water, and stir the mixture at the same time.

[0046] 3) Put the aluminum pot into the incubator, set the temperature at 15°C, stir the seed mixture once every 12 hours during the period, cultivate for 72 hours, use an 8-mesh round hole sieve (3mm) to separate the cabbage and gourd seeds, put the cabbage seeds in Dry in a drying oven at 28°C until the moisture content is below 7%, and then seal and store for later use. The gourd seeds continue to be cultivated for 48 hours, and then put them in a drying oven at 35°C for drying until the moisture content is below 7%, and then seal and store for later use.

Abstract

The invention provides a seed germination method, and belongs to the technical field of seed germination. The seed germination method comprises the following steps of (1) mixing first seeds and second seeds to obtain mixed seeds; (2) pre-wetting the mixed seeds obtained in the step (1) to obtain pre-wetted seeds; (3) culturing the pre-wetted seeds in the step (2) for 2-3 days, and screening the first seeds and the second seeds; drying the screened first seeds until the water content is below 7% to obtain dried first seeds; (4) continuously culturing the screened second seeds for 2-3 days, and then drying the second seeds until the water content is below 7% to obtain dried second seeds, wherein the first seeds are brassica seeds of cruciferae, and the second seeds are solanaceous seeds and / or melon seeds. The seed germination method can simultaneously realize germination of 2-3 types of seeds, and is low in cost and high in efficiency.

Description

technical field [0001] The invention belongs to the technical field of seed germination, and in particular relates to a seed germination method. Background technique [0002] Seeds are the most basic means of production in agricultural production. In order to promote seed germination and seedling formation, seed treatment before sowing is the primary link in production. In 1973, Heydecker in England used osmotic agent to treat the seeds at a certain temperature and time, and then dried the seeds, and found that the treated seeds could germinate neatly in a short time at a lower temperature (Zheng Guanghua, Xu Benmei, Gu Zenghui. PEG The effect of "priming" seeds [J]. Acta Bot, 1985, 27(3): 329-333; Hu Jin. Seed priming and its effects [J]. Seeds, 1998, 17(2): 33-35), This seed treatment method (Seed Priming) is also known as initiation in China. Seed priming is to control the water absorption of the seeds, so that they stay in the second stage of imbibition, carry out pre-...
