Other names for mustard greens are: cover greens, mustard greens, hanging greens. Annual herb, 30-150 cm tall, usually glabrous, sometimes young stems and leaves thorny, frosty and pungent; stems erect, branched. Mustard prefers cold and humid conditions, avoids heat and drought, is not frost-resistant, and requires strong light conditions. It requires cool temperatures and long day conditions to produce buds, shoots vines, flowers and fruits. Mustard does not have strict soil requirements and is generally suited to sunny, irrigated, drained moisture and fertilizer. Planting is generally done in small, high ridges, which are conducive to ventilation and light penetration. Fertilization is based on the principle of base fertilizer plus follow-up fertilizer, and the base fertilizer is based on farmyard manure plus compound fertilizer potassium chloride. Choose high-quality vegetables, sow the seeds at the right time, mix with the right amount of fine sand, and spread evenly. After sowing, cover with fine soil or grass ash, then cover with grass material and drench with water. Strip off the grass in time after germination.

When sowing, the bottom layer of moisture should be sufficient, and the mulch should be loose and soft, which is conducive to seedling emergence. The mulch should not be too thick, so as not to affect the emergence of seedlings. Usually about three days to emerge. Because of the rapid emergence of seedlings, it is necessary to sow seeds in time. In general, seedlings should unfold in the first true leaves to prevent crowding to form tall seedlings. Watering should be reasonable during this period, both morning and evening on warm days, but not too much. Fertilizer in the form of urea and potassium chloride should be applied to the middle of the furrow, and then the whole furrow should be covered with soil. Be careful not to bury mustard roots. During this period, we should plow and weed to keep the soil loose and increase its permeability. The first prerequisite for vegetable cultivation is that the growing environment of vegetables meets the environmental requirements for vegetable growth, so it is necessary to grow cabbage mustard according to the regional environmental characteristics of a particular region. Cabbage mustard with core is highly adaptable to growth, can tolerate some cold and has a short growing period. It is an ideal raw material for pickles due to its tight and full leaf bulb, thick leaves and high yield. Mustard is widely welcomed by vegetable farmers and enterprises because of its good commercialization and high yield after processing. Mustard cultivation temperature should be controlled between 15 ℃ - 25 ℃, in the selection of varieties should choose some compact early maturity varieties.

The preferred method of sowing should be seedling transplanting in order to facilitate seedling management and cultivation. If possible, you can also use hole tray nursery, usually in late July and early August for planting. At the same time, the requirements for the nursery site are high. Typically, the nursery site needs to have a high capacity for retaining fertilizer and water, and a well-developed drainage and irrigation piping system. The entire seedbed should have fine features and be slightly curved like a turtle's back. During the nursery process, attention should be paid to the protection of seedlings to ensure that the seedlings will grow neatly after emergence, and a series of nursery preparation and management work should be done.

If the temperature of the region during the seedling period is rising or in a period of drought, the seedlings are prone to die after seedling, the staff should deal with the dead seedlings in a timely manner, and it is best to achieve a comprehensive balance. Because of the rapid growth of kale mustard after the planting stage of survival, it is necessary to pay attention to the supply of fertilizer and water in the cultivation stage. In the early stages of plant growth, drought tolerance, moisture retention and timely fertilization can be incorporated into the climate of the area. Fertilizer rates generally range from light to heavy, usually using urea or other fertilizers. Fertilizer every 8 days or so, two consecutive fertilizer; cabbage heart rate at about 6%, usually in late September and early October to apply heavy fertilizer. Generally 15 kilograms of urea and 7.5 kilograms of potassium chloride are mixed or other corresponding fertilizers are used. After heavy fertilizer, according to the growth and fertility of cabbage flexible fertilization.
