Cauliflower plants are taller than ordinary vegetables, so it needs more water during its growth. Water properly when sowing and seedling emergence. Keep the soil moist, but pay attention to the amount of water to prevent water accumulation in the field, so as to promote the rooting of cauliflower roots. Ensure that the drainage ditch in the field is always in a smooth state, so as to drain water in time in case of sudden rainstorm. When cauliflower needs water most in rosette stage and flowering stage, it is necessary to ensure sufficient water supply. Pay attention to prevent flooding and root rot when watering.

2. Rational topdressing

As I said before, cauliflower is relatively large, so we should not only water it more, but also fertilize it more. With the increase of water demand, the amount of fertilizer needed in rose period and flowering period will also increase. In these two stages, we will increase the proportion of nitrogen fertilizer in fertilizer and promote the growth of cauliflower. In prosperous times, it is necessary to supplement enough trace elements to ensure comprehensive nutrition and prevent malnutrition of cauliflower. Then, according to the growth of cauliflower, apply Bika water-soluble fertilizer appropriately, but everyone should pay attention to proper watering after fertilization to prevent high concentration burns.

3. Fold leaves to cover flowers

Cauliflower must be covered well from flowering to expansion. If it is not covered in time, it will hinder the growth of buds. The color changed from yellow to purple. In severe cases, yellow fluff and new leaves will grow, which will lead to the decline of quality. Therefore, when the cauliflower grows to the size of a fist, it is necessary to fold the leaves in time and cover the buds to prevent direct sunlight. If there are not enough leaves, after the flowers appear, you can tie the leaves inside with straw and fold the old leaves over the flowers.

4. Disease control

Diseases may occur in the whole growth cycle of cauliflower, different diseases and insect pests may occur in different growth stages, and some diseases may occur at any growth stage. Diseases and insect pests will seriously threaten the yield and quality of cauliflower and affect the economic benefits of planting. Therefore, we must strengthen management, disinfect the vegetable garden regularly, remove the sick and disabled in the vegetable garden, eradicate the diseased plants and prevent the spread of diseases. After the disease occurs, the specific pests and diseases should be checked immediately, and then the corresponding drugs should be used for spraying prevention and control to reduce the affected area.
