How to grow mustard for stem?

How to grow mustard for stem? Please introduce the methods of planting and management of stem mustard, alias green vegetable head, cabbage, mustard, water chestnut, etc., which is a variety of Brassica cruciferae, which can be boiled, soaked, cooled, fried and pickled. The variety with protuberance on the inflated stem is suitable for processing, and the processed product is called mustard. Jiao Xin, a farmer in Shizhuang village of our city, has successfully planted it for 6 years by using the winter greenhouse, which not only meets the needs of consumers, but also obtains better benefits. First, select varieties with wide adaptability, strong stress resistance, not easy bolting, strong growth, strong cold resistance, high quality and fragrance, and great potential for increasing production, such as extra-large pickles, selected mustard mustard, goose cabbage, Zaoyuan 12, Zaoyuan 13 and so on. Second, apply basic fertilizer for soil preparation to select deep, loose and fertile soil, applying 5000-6000 kg of high-quality rotten circle fertilizer per mu and 50 kg of superphosphate. After the previous harvest, deep ploughing fine rake, leveling for the border, the width of the border is 1.2 meters. Third, cultivate strong seedling greenhouse stem mustard, raise seedlings in autumn in the Huang-Huai valley and harvest in early spring. The sowing date should not be early, although early sowing can prolong the growing period, it is easy to be infected with virus and early bolting; late sowing is not susceptible to virus and bolting, but the growing period is short, which affects the yield. It is suitable to sow seeds in the first ten days of August and September. Spread the seeds evenly on the seedbed, cover the fine soil 1.5-2 cm after sowing, and then cover 25 mesh insect control nets to prevent aphids from spreading diseases. 0.4-0.5 kg of seeds per mu. Seedbed: Honda = 1:10-15. Seedlings with 2 true leaves once, and seedlings with 3-4 true leaves once again, remove inferior seedlings, weak seedlings and diseased seedlings, and keep row spacing of 6 cm. Proper watering during the seedling stage can ensure the healthy growth of the seedlings. 4. Planting when the seedling has 5-6 true leaves and the seedling age is 30-35 days, it is more suitable for planting. If the seedling age is too small, it is not conducive to improve the land utilization rate; if the planting is too late, the seedlings are crowded and easy to grow. 4000-5000 plants per mu, row spacing 40 cm, plant spacing 33-40 cm. In order to improve the processing quality of mustard mustard, the density can be increased appropriately. Transplanting was carried out according to the order of opening holes, watering, placing seedlings, covering soil and so on. Large and small seedlings should be planted separately to facilitate balanced growth. 5. Fertilizer and water management in terms of water management, the soil should always be kept moist. Under the premise of applying sufficient base fertilizer, the general topdressing is 3 times. For the first time, after the slow seedling to before the formation of the first leaf ring, 15-20 kg of ternary compound fertilizer was applied per mu (15% of N, P, K content). The second time after the formation of the first leaf ring, the stem began to expand and gradually formed the second three-leaf ring. At this time, the growth rate of the stem is faster, chasing 40-50 kg of ternary compound fertilizer per mu. The third time in the peak period of stem growth, 20-25 kg of urea was applied per mu with water. After the plants were ridged in the middle and later stage, the field activities should be reduced as far as possible so as not to damage the leaves. 6. The optimum temperature for regulating leaf growth of stem mustard is about 15 ℃, and the average ten-day temperature for stem expansion is 8-13.6 ℃. In this range, the higher the temperature, the faster the growth. Therefore, according to the plant growth condition and the change of external air temperature, we should buckle the shed at the right time (mid-late October), uncover the grass properly, especially in the cold day, increase the light, create a suitable environment for stem and leaf growth, in order to improve the quality and increase the yield.
