1、 Curing method

1. Soil: kale has strong adaptability to soil, and sandy loam is the best. It needs to absorb a large amount of nitrogen, phosphorus and potassium. Absorb a large amount of fertilizer during budding. The absorption of fertilizer is different in each period of growth. Pay attention to appropriate adjustment

2. Temperature: mustard likes a mild growth environment and has strong heat resistance. The best growth environment is between 25 and 30 degrees. It grows slowly below 20 degrees, and the growth of mustard still needs a large temperature difference between day and night

3. Light: it belongs to light loving plants. During the growth period, it has high requirements for light, needs sufficient sunshine and is not resistant to dark environment

4. Moisture: it likes a relatively humid growth environment. During the growth period, the soil needs a lot of moisture. Compared with other vegetables, it has strong waterlogging resistance, but the soil is too wet or ponding will affect the growth of roots

2、 Breeding skills

1. Sowing: direct seeding or seedling cultivation can be adopted. Seedling cultivation should be in sandy loam with good drainage and air permeability. More fertilizer should be applied during land consolidation to provide sufficient nutrients for mustard

2. Winter: mustard likes a warm and humid environment. In winter, we should take certain warm measures to avoid freezing the roots

3、 Diagnosis and treatment problems

1. Disease: mustard is prone to black rot, which is caused by bacteria and is easy to occur under high temperature and humidity. When the disease occurs, it will cause the leaves to wither and die. When it is found, it must be removed in time and sprayed with bactericide for treatment

2. Insect pests: common insect pests include Pieris rapae and aphids. If found, they must be isolated in time to avoid contamination with other branches and leaves. In the seedling stage, insecticide or trichlorfon 1000 times liquid should be sprayed

4、 Other issues

1. Whether it is poisonous: the flower moss and tender leaves of mustard can be eaten, fresh and delicious, so it is non-toxic and can be cultured at ease

2. Indoor breeding: as kale is a light loving plant, it needs sufficient sunshine for growth, otherwise it will affect the growth of plants. Therefore, it is not recommended to breed indoors, generally in a sunny and ventilated place
