1、 Curing method

1. Soil: the soil is loose, fertile and has good drainage performance. It is more suitable for the growth of potherb mustard. Sandy loam can be selected

2. Water: in its vigorous growth period, sufficient water is necessary. The amount of watering is generally based on the standard that there is no ponding. If the water absorbed by potherb mustard is insufficient, it will increase the fiber material and reduce the variety

3. Nutrients: before planting potherb mustard, the soil should be turned over first, and then exposed to the sun for sterilization. Then use chicken, duck, pig manure and human manure as base fertilizer to sprinkle evenly on the soil, which can make it fully absorb nutrients after planting

4. Light: it likes to grow in a cool environment with fresh weather and sufficient sunshine, which is more conducive to the formation of its flower buds, can also promote the growth speed and avoid the direct exposure of high temperature and strong light

2、 Breeding skills

1. Pruning: during the growth period, the stems and leaves at the outermost layer of the root often wilt and rot. they should be properly pulled out and pruned to prevent the rotten stems and leaves from infecting the growth of other normal stems and leaves. It shall also loosen the soil and remove weeds properly

2. Breeding: the breeding method is generally flat border direct seeding, first fertilizing, turning over the soil, then sowing, watering to keep the soil moist, and the seedlings can grow in about half a month

3、 Diagnosis and treatment problems

1. Yellow striped beetle larva: yellow striped beetle larva is very harmful to the root of potherb mustard. If it is not killed in time, it will seriously affect its growth. It can be diluted and sprayed with phoxim

2. Root swelling: This is a fungal disease. Reasonable sterilization and chemical prevention can be well controlled. When root swelling occurs, it is necessary to choose the configured lime water for irrigation, which can be effectively prevented and controlled

4、 Other issues

1. How to spend the winter: potherb mustard is a plant that can resist low temperature. When the temperature is low in winter, it will not cause frostbite and freezing death to potherb mustard. However, when the snow is thick, it should be properly removed

2. Edible: potherb mustard is edible. It is a common vegetable. The main purpose of cultivation in China is to eat it
