The technique of growing cabbage
The main cultivation techniques are described below:
1. Varieties selection. The choice of heat-resilient varieties, adapted to the requirements of high summer temperatures, is generally based on local conventional varieties or pre-literated varieties such as no. 5 and changzhou plateau。
2. Cultivation. The summer cabbage is usually planted in the first half of june and in the second half of august, with more stripping or sowing at 450-500 grams per acre。
3. Net cover, shed temperature control. It is covered by an anti-verbicide net without breaking up. House temperature control, pest control due to use of nets

Net shade rates are high and, if they are low, the temperature in the shed remains high, which is detrimental to cabbage production, causing foliage and affecting quality. As a result, a net of shades is added to the roof of the shed at high temperatures, which allows cabbage to grow normally。
4. Sapling. After 2-3 days of seedlings, the first seedlings take place when the seedlings begin to “cruise”, it is advisable to visit them early and late, and the second seedlings take place when the four-5 leafs grow. At the same time, market conditions can be combined to allow for the start of the marketing of seedlings and the removal of weeds from them。
5. Fertilizer water management. Fertilizers are usually applied in a manner that is in the form of hard and light application, based on a base of 1,500 kg of decomposed organic or 25 kg of compound fat in acre, a diet of 2. 5 kg of urea and 400 kg of water, followed by one application every 5-7 days, often combined with fertilization, in the event of drought, with two waterings early and late, in addition to increasing the amount of water used in the pursuit of fertilizers, sufficient to meet the demand for moisture for the growth of cabbage, and in the event of storm rain and monsoon plumes, to clear trenches and reduce groundwater levels in a timely manner。
Pest control. The main pests are aphids, larvae, larvae, moths and so on, and it is generally possible to treat biological pesticides, such as betelling, one or two times earlier。
7. Timely harvest. They are usually collected 20-25 days after planting, and can also be collected several times, i. E. Once after planting, once after fertilizing, and once after fertilizing。
