Cabbage Cultivation Technique Cabbage has a wide adaptability and can be cultivated in four seasons, but it is cultivated in autumn and winter. Summer cabbage, also known as hot cabbage, is simple to cultivate, focusing on the cultivation techniques of autumn and winter cabbage.
(1) sowing seedlings: autumn and winter cabbage is generally transplanting seedlings. The middle and lower reaches of the Jianghuai River can be planted from mid-August to mid-October, and cultivation of greenhouses can be delayed until November. Southern China can sow in September-December. Seedbed land should be avoided for continuous cropping, with strong fertility and good drainage. After the harvest, we must plough the fortress in time to remove debris, and if necessary, disinfect the soil to reduce pests and diseases. Appropriate dilute sowing at the time of sowing, Meg easily lead to leggy, early jointing, affecting the quality of seedlings. Seeding rate per mu l-l. 5 kg. 1 mu seedlings can be planted 6-7 acres of field. Appropriate sowing of cabbage for 2 to 3 days can emerge. After the emergence of seedlings and time, the general seedlings 2-3 times. The temperature is suitable, and the seedling age is generally no more than 25-30 days. The late autumn and spring sowing seedlings are a little longer, and the southern China is relatively short.
(2) Planting: Chinese cabbage is harvested for young plants, so most varieties are suitable for dense planting. This will not only increase production, but also improve the quality of the plant. In the year of virus disease recurrence, it is particularly necessary to significantly increase the density. The specific density depends on the variety, season and cultivation purpose. Planting spacing is generally 26 cm and 26 cm, and about 7500-8000 plants per mu. If planted in late November, the plant spacing is 20 centimeters and 20 centimeters, with about 13,000 plants per mu. Pickled cabbage line spacing is 33 cm 26 cm, about 5000 to 6000 per acre. Pure seedlings, strong seedlings and disease-free pests should be selected when planting.
(3) Field management: Cabbage has a shallow root distribution and poor absorption capacity. Therefore, strict requirements are imposed on fertilizer and water, and sufficient fertilizer and water should be continuously supplied during growth. Fertilizer is mainly available nitrogen fertilizer, human urine or urea is the best. From planting to harvesting, it is necessary to top-dress 4-6 times, starting 3-4 days after planting, and top-dressing once every 5-7 days. The concentration will increase gradually from light to heavy. 15-20 days after planting, one fertilization should be applied and one fertilization should be carried out one month after planting. Fertilizer amount per person per mu mu of urine 1000-1500 kg, or 10-15 kg of urea. The foliar spraying with a concentration of 0.75% urea solution can promote the growth of cabbage leaves and enhance the color. White. The vegetables should be fertilized before 10-15 days before harvest to make the organization full. Otherwise, there will be too much fat and water in the later stages, and the tissue will be soft and not suitable for marinating. Cabbage irrigation is generally performed in combination with topdressing, and each cultivator can be properly cultivated and loosened to prevent loss of fertilizer and water.
