It's cultivation is divided into two kinds of dry planting and water planting, the north is mainly dry planting, the south dry planting and water planting coexist; early cultivation is mainly dry planting, most of the middle and late maturity cultivation using water planting. Its sowing, seedling two ways of technical points are:
Dry planting more seed propagation, open field direct broadcasting, seedling transplanting can be, sowing period is generally in April in the middle and late. Transplanting, the use of flat bed seedling, per mu seedbed sowing seeds 10 - 15 kg, seedling height 15 - 18 cm when planting;
Cabbage seed coat is thick and hard, slow water absorption, early spring seedling need to be soaked, germination, sowing covered with Plastic film to increase the temperature, moisturizing, to be seedlings out of the soil and then remove the film. In addition, can also be taken during the growth of about 15 cm for the top cuttings propagation, as long as the cuttings field soil moisture is suitable, the cuttings will soon grow adventitious roots, and draw new tips.
Water planting more vine seedlings.
With the previous year selected by the protection of the safe overwintering of the seed of the vine germination inserted in the nursery beds, seedling height of 30 cm or so to take the vine, to promote the emergence of adventitious roots down the vine, upward draw the long lateral branches, and then successively draw out the lateral cuttings with a certain size of the fixed planting.
The main points of seedling technology
Hollow cabbage, also known as water spinach, vine vegetable, is a trailing aquatic vegetable native to the rainy areas of southern China. Cyclophyllaceae, sweet potato genus, annual or perennial herbs. The young tips and leaves are fried or made into soup, rich in various vitamins and mineral salts. In the shoots of cabbage, calcium content is more than 12 times higher than tomatoes, and contains more carotene.
In recent years, in the north, the use of daylight greenhouse for anti-seasonal cultivation has been the development of the New Year, winter, early spring is quite popular with consumers. Daylight greenhouse light insulation performance is superior, encountering catastrophic weather to subsidize heating, always maintain normal growth, can be harvested many times, from winter to early spring, the total output per acre can reach more than 5000 kilograms.
