Planting techniques of Roman cauliflower

Soil preparation: although Roman cauliflower likes a humid environment, its waterlogging tolerance is very poor, so in rainy areas and places with high groundwater levels, it is cultivated in deep trenches and high beds to facilitate drainage, which is a key to the successful cultivation of Roman cauliflower.

Seedling planting: the method of raising seedlings of Roman cauliflower is the same as that of cabbage, which can be carried out with reference to cabbage. The nutritional area of Roman cauliflower varies from variety to variety. Early-maturing varieties cultivated in the south usually plant three rows on a 1.7m (continuous trench) wide border, arranged in a triangle, and two rows on a 1.3 m (continuous trench) border. Both middle-maturing and late-maturing varieties planted two rows on the border.

Irrigation: regular and quantitative irrigation is very important for the normal growth of plants. It is best to keep the soil moist and keep the water content stable and consistent.

Other management: after heading, try to prevent the fruit from being exposed to strong light, so as to ensure the quality of the fruit ball. In mild areas in winter, the harvest time can be prolonged and the development of lateral flower heads can be increased. In the process of Roman cauliflower cultivation, lateral branches should be fully utilized to form florets, and the yield of lateral branches accounts for 25-30%, so the use of lateral branches is very important. After the main flower bulb was harvested, the plants were arranged, the old leaves were removed, fertilized, loosened and cultivated to promote the development of lateral buds below the top flower bulb, and when the small flower bulb was formed, it was harvested in batches.

Pest control: mainly black rot, black spot and downy mildew; pests include vegetable aphid, cabbage moth, rapeseed butterfly and so on.

Harvest: the harvest must be timely, the harvest is too early, the flower bulb is not fully developed, it will reduce the yield, too late, the bud ball will be released, the sphere is uneven, the bud thickening affects the quality, and is not resistant to transportation, so timely harvest is very important and should be picked every day. When collecting the main ball, cut off the stem when the stem is 25 centimeters long, remove the petiole and pack it to the market immediately. The harvest time should be in the early morning.
