The flower ball is round, white and of good quality. the single ball weighs 0.4-0.8 kg.

Key points of cultivation

① seedlings were raised at the right time. Select the land with high dryness, good drainage and fertile soil to do seedlings, and the seedling bed should be filled with sufficient bottom fertilizer and sowed from June 15 to 20, with a sowing rate of 30-50 grams per mu. In hot weather, you should pay attention to shade. Strictly guard against cabbage insects and underground pests at seedling stage. Water frequently every day to keep the seedbed moist.

② was transplanted in time and close planting was reasonable. The seedlings can be transplanted when they grow to 3-5 true leaves from July 15 to 20. Before transplanting, the seedling bed was watered thoroughly, and the transplanting effect was good in the afternoon, with row spacing of 50-55 cm, plant 40-50 cm, and 2500-3000 seedlings per mu. When transplanting, the seedlings are planted separately, which is easy to manage.

③ increased manure application and topdressing irrigation. 3000-5000 kg agricultural fertilizer and 10 kg diammonium phosphate are applied per mu. 15 kg nitrogen per mu in rosette stage, 15 kg urea per mu in rosette stage, and timely watering combined with topdressing.

④ covers the bouquet frequently and harvests it at the right time. When the flower ball is formed, the work of covering the ball should be done carefully to keep the ball white and tender, and the old leaves can be used to cover the ball. When the basal flower branch is slightly loose, it is the harvest time.

⑤ short-term storage. The seasonal price difference can be used for short-term storage, and the planting method for the smaller flower heads can prolong the growth period and increase the yield.
