(4) Sowing First, the seedbed is watered, the seeds are broadcast live, sprinkled, covered with soil 1 cm thick, covered with shade nets or weeds and other shades, 6-7 days can be emerged. (5) Seedling management After the emergence of the seedlings, the sunshade net and the shade are exposed, and the small arch shed is covered and the sunshade net is covered. After the cotyledons are unfolded, the weeds are combined with the weeds, and the seedlings are 5-6 cm apart. Seedlings can grow a water after growing a true leaf, but not flooding. After 2 pieces of true leaves, 500 g of urea was applied in combination with watering 40 m2 seedbed. 5-6 true leaves 5-6 true leaves can be colonized. Watering and dicing 3 to 5 days before planting, transplanting with nutrient blocks. In this period, attention should also be paid to the treatment of pests and diseases. 2. Cauliflower fertilization preparation 667 square meters of soil and fertilizer 4-5 tons, ternary compound fertilizer 50 kg. The ploughing is flattened, and the planting raft is made according to the specification of 1.2 m in width and 30 cm in shovel. 3. Cauliflower colonization Planted in late June - late July. According to the line spacing of 5040 cm, the planting hole was planted, and about 667 square meters were planted with about 3000 plants.

(3) Before the formation of the flower ball, it can be sprayed with 0.5% urea solution or increased production for foliar top dressing 1-2 times. (4) At the beginning of the ball formation, the 0.2% borax solution is sprayed 2-3 times. Stop watering before harvesting.
