Winter cabbage is an efficient and cold-tolerant vegetable variety that was promoted by the Association of Peony District of Heze City, Shandong Province in 1996. Under the condition of normal cooling, the variety has no protection at 10-13°C, can safely pass through the winter, and does not need to fight drugs, pests, pollution, labor and time, and is easy to manage. It only needs to change the planting mode. Harvest from December to March, which can be listed 1-2 months ahead of greenhouse crops, yielding 3000-5000 yuan per mu. First, the characteristics of characteristics: There are two varieties of spherical and bovine heart type. Plant development degree 55cm, plant height 27cm, 15 functional leaves, leaf ball height 13cm, center column 5cm, dark green leaves, crisp leaf quality, good palatability, wax powder medium, ball compaction. Hard to crack, strong resistance to bolting, high cold resistance. The spacing is 5040cm, about 3300 acres are planted, and the single ball weighs about 2kg. 5000-6000 kg per mu. Second, the cultivation points: winter soy generally have two sowing dates, the first sowing date is July 25 - August 5 seedlings, planting before September 15, seedling age 28-30 days, take different management measures, 12 Month - March can be listed on the market. The second sowing date is from October 1st to October 10th, and the seedling age is 40 days. In mid-November, Daejeon is planted and harvested before mid-April. Seedlings when the seedlings should not be too large, the general rhizome is not more than 0.6cm, no more than 7 leaves, leaves no more than 7cm wide, otherwise, through vernalization, the phenomenon of early bolting occurs. The variety must be sown on a strict schedule, otherwise it will bolt, causing loss. Third, the winter and spring management: This variety of winter cultivation requires a full application of base fertilizer. Usually 667 square meters with pear base applied high-quality organic fertilizer 3000 kg, 50 kg of diammonium. For the first sowing date (that is, at the end of July and early August), chemical fertilizers are chased 1-2 times from September to October, and 15-20 kg of urea are chased each time, and timely watering promotes growth. In early November, it is necessary to control fertilizer and water to make it grow thick. In late November, it will be poured over winter water to enhance cold resistance. In special cold areas, mulches must be used to prevent freezing and promote growth. For the second sowing date (ie October 1st to October 10th), after planting watering, the mulch or arch shed should be buckled for winter. After the beginning of spring, the temperature rises and begins to grow. From the end of February to the beginning of March, the seedlings grow to 12-14. When a true leaf was broken down in stages, it was cooled down and then fell to the ground. From late March to early April, it was a period of rapid growth and growth. It took 1 chemical fertilizer and 15-20 kg of chemical fertilizer. In mid-April began harvesting market. China Agricultural Network Editor
