Variety selection: Autumn broccoli, the early positive temperature season, should use heat-resistant varieties, commonly used varieties are: the Netherlands snowball, Fujian 80 days, Japan Snow Mountain and so on.
Site Preparation and Base Fertilizer: Although broccoli enjoys a humid environment, it has poor resistance to turf. Therefore, in areas with high rainfall and high groundwater levels, deep sorghum cultivation is used to facilitate drainage. This is a key to the success of broccoli cultivation.
Nursery and colonization: Cauliflower seedlings are the same as cabbages, and can be referenced to cabbage. The area of ​​broccoli colonization depends on the variety. Planting early-maturing varieties in the South is usually planted in three rows of 1.7 m (Lenggou) wide clams, arranged in triangles, and two rows of clams in 1.3 m (Lenggou). The mid- and late-maturing varieties were all planted on the second line of the alfalfa.
Field management: The types of topdressing fertilizers are generally dominated by nitrogen fertilizers throughout the growing season. When entering the flower bulb formation period, phosphorus and potassium fertilizers should be added appropriately. However, the current fertilization habits tend to focus more on nitrogen fertilizers. The amount of topdressing fertilizer per acre in the south is generally as follows: 7.5-10 kg of ammonium sulfate for early maturing varieties; 15-20 kg of ammonium sulfate for medium maturing varieties; 75 kg for plant-wood ash; and 20-30 kg of ammonium sulfate for late-ripening varieties and 100 kg of plant ash.
Pest control: mainly black rot, black spot, and downy mildew; insect pests are rape, Plutella xylostella, cabbage butterfly and so on.
