1, growing environment: like warm and humid climate, seedlings can tolerate low temperature around 0 ℃, -2 ℃ below will appear frost. Prefer sunny, afraid of drought, avoid stagnant water. To loose fertile, well-drained sandy loam, oil sandy soil, sand trap soil cultivation is appropriate. Avoid continuous cropping.

2, cultivation technology of wattle and daub can be sown and sown in strips, mainly sown in strips, spring sowing, summer sowing can be. According to the row spacing of 20 cm open 0.5 cm deep shallow ditch, the seeds evenly sprinkled into the ditch or bed, covered with a thin layer of fine soil, a week or so that is germinated. Seed propagation. In the field to choose strong plants, branches, spikes and dense, and no pests and diseases of single plants or plots left for seed, the seeds need to be fully mature, full, dark brown or brown Ming harvest. Direct sowing or seedling transplanting method. Spring sowing, in late March to early April for the right time: autumn sowing in September-October; hole sowing, row spacing 17-500px each. 3.75-4.50kg per 1hm2. strip sowing, row spacing 500px, 125px deep. 7.50kg per 1hm2. spreading, 7.50-11.25kg per 1hm2. The amount of seed used for 1hm2 is 11.25-15kg, and the seedlings are transplanted in May-June when they are about 375px tall.

3, pests and diseases control: the attention of drainage or choice of raised beds planting, the onset of sterilization agent 401 800 times liquid or 50% carbendazim 1000 times liquid watering. Ink spot disease, you can pull out the diseased plant and burn it, or use 65% diclofenac zinc wettable powder 500 times liquid control. There is also thorn stem blight damage. Insects such as silver-striped night moth damage.

4, field management: seedling period should keep the soil moist. Seedlings 5 cm high time seedlings, plant spacing to not crowded appropriate, seedling attention to weeding. Disease and pest control: standing wilt, strengthen field management, do a good job of drainage, the early onset of the disease with 50% methotrexate 1500 times liquid control. During the growth period, pay attention to seedlings, replenish seedlings. Plowing and weeding 1-2 times, shallow hoeing during the seedling period, so as not to damage the seedlings. Fertilizer to nitrogen fertilizer, appropriate application of phosphorus and potassium fertilizer. General fertilizer 3 times. Seedling period in case of drought timely watering; in case of flooding timely exclusion of stagnant water.

5, harvesting and processing: spring sowing of medicinal mustard, harvested at half-seed and half-flower; summer sowing of medicinal whole thorn mustard, cut in the fall, dried and bundled into a handle for the whole thorn mustard.
