1. When preparing the land on the ridge, it is necessary to choose the land with Gao Shuang topography, good drainage, ventilation and light transmission, loose and fertile soil, clean up the previous crops in time, plow and expose in the sun in advance, and apply the seedbed base fertilizer evenly, and apply the decomposed organic fertilizer 1000 kg, compound fertilizer 20 kg and phoxim granules/kl per mu.
2. Seedling management: before sowing, seed is dressed with 800 times solution of new high-fat film (which can repel underground pests and diseases, isolate virus infection, strengthen respiratory intensity and improve seed germination rate) and water the soles of feet; Then the treated seeds are evenly scattered in the seedbed, and the sowing amount is appropriate. After sowing, the soil is covered with 1- 1.5 cm thick nutrient soil, and 800 times of new high-fat film is sprayed to keep warm and moisturize, increase fertilizer and promote seedling emergence.
3. Transplanting for field planting: For field planting, loam or sandy loam with strong water and fertilizer conservation should be selected, and sufficient base fertilizer (2000 kg of decomposed organic fertilizer, 50 kg of compound fertilizer, plus 65438+ 0.5 kg of borax) should be applied, fully ploughed, and soil preparation should be used as border; Reasonable close planting, watering root water while planting, rehydrating once every other day and spraying 800 times of new high-fat film in time can prevent bacterial infection, improve the ability of seedlings to resist natural disasters and shorten the slow seedling stage.
4. Field management: After the plants return to normal development at the end of the slow seedling stage, timely intertillage and weed control, cultivate soil and root, timely spray seedling fertilizer (2.5 kg urea mixed with water per mu) and spray a new high-fat film for 800 times to improve the nutrient utilization rate; Spraying Zhuangganling in time at budding stage can make the stems and bulbs of plants stout, improve the disaster resistance, reduce the dosage of pesticides and fertilizers, reduce the residual poison and improve the natural taste of broccoli.
5, pest control, broccoli is prone to downy mildew, soft rot, diamondback moth, cabbage caterpillar, cabbage caterpillar. According to the requirements of plant protection, chemical agents (such as 70% mancozeb wettable powder, 72% agricultural streptomycin wettable powder and 50% phoxim emulsifiable concentrate) were sprayed for killing, and the new high-fat film was sprayed 800 times to enhance the control effect.
