First, cultivation methods and seasons
The adaptability of broccoli is stronger than that of broccoli, and there are many varieties. According to different climates, different varieties can be selected and cultivated in four seasons.
Second, sowing seedlings
Broccoli is a high-grade dish with expensive seeds. The seedbed must be carefully grounded, and the base fertilizer should be applied to make the soil fine, flat and fat, and the seed should be 15-30 grams per mu and the seedbed 6-7 square meters. In the low temperature season, the small arch shed can be used to cover the heat preservation. In the high temperature and rainy season, the nursery should use the sunshade net to cover the shed, and cool down and prevent rainstorm. After the planting, the cover is gradually removed and the seedling is carried out. Summer and autumn can be planted for 25-30 days, and winter and spring sowing is 40-50 days.
Third, colonization and density
Before planting, you should choose the ground and apply the base fertilizer. Each mu of farmer's fertilizer is 2000-3000 kg, compound fertilizer is 30 kg, borax is 0.5 kg, the rainy season is made into sorghum, and the dry season is flat or low.
Fourth, field management
After colonization, before cultivating, cultivating 2-3 times, loosening the soil and removing weeds is conducive to the growth of broccoli.
After planting and slowing down the seedlings, the number of watering should be reduced appropriately. The period of vegetative growth and the period of flower formation should increase the amount and frequency of irrigation, prevent drought, pay attention to drainage during the rainy season, and prevent waterlogging.  Wei  Rong
