1, characteristics The outer leaves are mostly green, and the leaves have various forms depending on the species. The autumn sowing varieties are early-maturing and mid-late-maturing varieties, and the growth period ranges from 50 to 80 days. The plant type is mostly erect, the leaves are stacked and the inner leaves are brightly colored. After being cut, the sun is slightly more exposed and brighter. The ball is tight, the net rate is high, and the taste quality is excellent. Strong resistance to viral diseases, downy mildew and soft rot. During the growth period, the water consumption is very large, and a large amount of water is needed during the entire growth period. In the case of sufficient fertilizer and water, the yield is particularly high, and the average net production per mu is 6500 to 7,000 kg. 2. Requirements for soil and environmental conditions The roots of colored Chinese cabbage are mainly distributed in the shallow soil layer. Planting should be done in fertile, loose, ventilated, water-retaining and fertilizer-conserving sandy loam soil, loam soil and light clay plots. The thickness of the soil layer is required to be more than 50 cm and the pH value is 7 to 7.5; During the development period, it requires a mild and cool climate. It is tolerant to high temperatures during the seedling stage and the ball stage. It is not tolerant of high temperatures. When the temperature reaches 32°C, the growth is very weak, and it is most suitable to grow at a temperature of about 10-22°C; budding stage and seedlings The suitable temperature is 20～25°C; the light requirement is not strict, and it can also grow normally under proper low light conditions, suitable for close planting, but the light yield is reduced; the long-day vegetative period is conducive to photosynthesis. Short days can promote the ball. 3, the requirements of fertilizer and water conditions Chinese Cabbage is a vegetable with a large amount of water, which requires less water during the germination period. Since the root system is very shallow during the seedling period, it should be watered regularly. The water requirement during the lotus sitting period is large, but the watering should be appropriate to prevent excessive water and cause leggy growth. Affect the roots under the bar and Baoxin; need for water increased during the ball period, should be a lot of water, prompting the rapid growth of leaf. Potassium uptake was greatest throughout the growth period, followed by nitrogen and calcium, and less uptake of phosphorus and magnesium. In the cultivation of colored Chinese cabbage, fertilizers should be combined with organic fertilizers and chemical fertilizers, and top dressings should be applied according to different growth stages. 4, cultivation techniques In the spring season, the seedlings shall be nursed or broadcast live at a minimum local temperature of not less than 5°C. Autumn sow cultivation is generally planted in North China in August and in mid-August. The Yangtze River valley will be sowed in August. South China will be sown from August to November. The alpine region should be advanced to June to July. The specific time should be based on the growth period of different species. , The best sowing time is the date when the growth period of the local cold weather is above -2°C. Premature, hot weather, susceptible to viral disease; too late, lack of growth period, affecting yield. Planting plots of Mushi rot 4000 to 5000 kg of organic fertilizer and 40 kg of potassium sulfate compound fertilizer as basal fertilizer. After deep-flushing at 30 cm, the sorghum was made into a 15 to 20 cm high sorghum plant with a width of about 1.3 meters per plant. 2 lines. At present, such cabbage seeds are relatively rare. Whether they are imported varieties or domestic varieties, the seed prices are correspondingly higher. Therefore, most of them are mainly seedling transplanting, which not only saves money, but also ensures that the seedlings in the fields are uniform and Miao Qi is convenient. management. Seedlings transplanted with 5 to 6 true leaves, the selection of a cool afternoon colonization, with the soil as soon as possible from the seedlings to hurt the root system, according to planting distance of 50 to 60 cm colonization, immediately after planting watering. After easing the seedlings to chase a fat tree, Mushi urea 20 kg, water every 5 to 6 days, keeping the soil wet and dry alternately. In the late stage of growing lotus, pour a large amount of water and carry out seedlings to promote a large number of root development. After the start of the package, increase the topdressing, watering, Mushi potassium sulfate 25 kg, urea 20 kg, ditch applied or acupuncture points. Stop watering 10 days before harvest. Throughout the growing period, special attention was paid to the damage of aphids and cabbage caterpillars, insect pests were found, and medicine was promptly controlled. To ensure normal growth during the growth period, fully increase production and obtain the best economic benefits. Disclaimer: Some articles in this website have been transferred from the Internet.
