Planting cabbage first cultivate strong seedlings, grow to a certain size after transplanting to fertile soil, because the cabbage need fertilizer and water demand is large, so be diligent watering and fertilization, and pay attention to the prevention and control of pests.

I, seeding nursery:

The implementation of vine nursery, with the previous year selected by the protection of the safety of over-wintering seed vines germination inserted in the nursery compartments. According to the compartment width of 1.5 meters, ditch width of 20 ~ 25 cm specifications of the whole field as compartments, the bottom of the fertilizer, to take a full compartment sowing seeding, seeding per acre seedbed seed vines 150 ~ 200 kg. Covered with plastic film after sowing to keep warm, moisturizing, to be removed after the seedlings out of the ground film. Seedling height of about 30 centimeters to take trailing, prompting the trailing node down the occurrence of adventitious roots, upward draw long lateral branches, and then use the successive draw out of the lateral branch cuttings with a certain size of the planting.

Two, fertilization transplantation:

The hollow cabbage on the soil conditions are not strict, it is appropriate to choose the terrain is low, the soil is moist and fertile clay loam on the cultivation. Bottom fertilizer to organic fertilizer, phosphate fertilizer, can be sprinkled with a certain amount of grass ash. Its cultivation specifications for the row spacing 30 ~ 35 cm, nest spacing 15 ~ 20 cm. In addition, can also be taken during the growth of 15 cm or so of the top again cuttings propagation, as long as the cuttings of the field soil humidity is suitable, the tips will soon grow adventitious roots, and draw new tips.

Three, field management:

Pre-period should be plowed in time to loosen the soil, improve the ground temperature. Plant growth period, fertilizer and water demand is large, to water diligently, watering (dry air, insufficient soil moisture, easy to lead to increased fibers in the hollow cabbage, affecting yield and quality), and combined with watering fertilizer. After the first harvest, 15 kilograms of urea or 20 kilograms of diammonium phosphate per mu, fertilizer is applied with irrigation. Afterwards, every 20 days or so, 1 times, mu of urea 3 to 5 kg. In the fall when the temperature turns cooler, it is necessary to plow and weed in a timely manner, and pay attention to the prevention and control of red spiders and other pests. In addition, too many lateral branches, branches and vines crowded and weak part to be thinning, so that the growth of branches and vines balanced, good ventilation and light, improve product quality.

Four, harvesting technology:

The timely harvesting is the key to high yield and high quality of cabbage. Production, generally in the seedling height of 25 ~ 35 cm or so can be harvested. In the first and second harvest, the base of the stem should be left enough 2 to 3 sections, in order to facilitate the sprouting of new shoots after harvesting, promote the development of lateral branches, and strive for high yield. After harvesting 3 to 4 times, the plant should be a re-harvesting, that is, the base of the stem only 1 to 2 books, to prevent the occurrence of too many lateral branches, resulting in weak and slow growth.
