The methods of germinating cabbage seeds are seed selection, seed dipping and germination.

1, seed selection: full of seeds, the size of the main seeds, dried out, there are wounds and the seed coat is broken out of the seeds do not.

2, soaking seeds: after microwave treatment of cabbage seeds, put them directly into clean water to soak for about two hours. Then put the seeds into the seed soaking agent to soak the seeds for about half an hour, after soaking the seeds take out and clean. The seed soaking agent can be purchased on the market, or you can make your own.

The use of chloropyrifos, algin, citric acid and potassium nitrate and other substances and water mixed together. Then during the soaking process, be careful to keep stirring for at least 10 minutes or so. After soaking with water and put into the nutrient solution to soak for two hours, and finally cleaned again.

3, germination: seeds after soaking with moist gauze to wrap the seeds, squeeze out excess water. Then put it in the environment of about 5 degrees refrigerated about 11 hours or so. Then take it out and put it in warm water at about 25 degrees to soak for half an hour. Finally, they are fished out and placed in a thermostat to germinate for about 22 hours. You have to observe the seeds frequently, when there are most of the seeds white, then you can start sowing.

Cabbage seedling technology

1, seeding seedling

Cabbage seeding seedling way more, can improve the nutrient bowl seedling, can also be installed through the substrate tray seedling, in the production of nutrient bowl seedling is more laborious, less used. The use of substrate tray nursery can choose 72 holes or 128 holes hole tray, substrate can choose grass charcoal, vermiculite or perlite and other lightweight substrate, they have a small specific gravity, the advantages of water retention and permeability.

Mix them with organic fertilizer at a ratio of 2:1, and then sterilize the substrate and hole tray well before sowing. Sowing is the substrate into the hole tray, watering water, put 2-3 seeds per hole, covered with a layer of film insulation and moisturizing, such as seedlings out of the ground after removing the film.

2, seedbed management

First of all, we must do a good job of temperature control, in the daytime to maintain about 25 degrees, at night to maintain more than 10 degrees can be, in the seedling period, the substrate must be in a moist condition. When the seedlings grow to more than 5 cm, you can spray foliar fertilizer once, the concentration of 0.2% urea and potassium dihydrogen phosphate solution, can promote rapid growth of seedlings. When the seedlings grow to about 10-15 cm can be planted.
