The main points of broccoli secondary ball management
Variety selection: Variety selection is very important. Early and middle-mature varieties must be selected as the main varieties for side branch production, such as excellent and green wind. Applying enough fertilizer: Because the broccoli is harvested after the first ball is harvested, the nutrients in the soil have been basically absorbed and used up. Therefore, in the management of broccoli secondary balling, more high-quality organic fertilizer and phosphorus and potassium fertilizers should be applied as base fertilizers, and 1500-2000 kg of decomposed organic fertilizer, 50 kg of superphosphate, and 10 kg of potassium sulfate should be applied per trench . For example, if rice fields are planted, then urea is applied for 7-8 kg; if the rice fields in high mountain areas are added with calcium, magnesium, and phosphorus fertilizers, 50 kg, and if the fields are short of boron, 1.5 kg of borax is added. Fertilizer is mainly used to promote the early branching of broccoli. Planting density: After the main flower bulbs are harvested, the plant type is properly dispersed to facilitate the growth and development of the lateral branch flower bulbs. Therefore, the varieties that need to be harvested with side branches should be well-dense and dense when planting. Excessive planting will cause poor ventilation of the plant, and the stems of the side branches are weak and easy to open, which affects the quality. Generally, the plant spacing is 55 cm and the row spacing is 60 cm, that is, it is suitable to plant 2100-2200 plants per mu.
