2. Fertilization technology. Under medium fertility level, the fertilization amount per mu of broccoli is 2500-3000 kg (or commercial organic fertilizer 350-400 kg), nitrogen fertilizer 20-23 kg, phosphate fertilizer 6-8 kg, potassium fertilizer 11-14 kg, according to crops. The variety and soil fertility should be adjusted appropriately. The nitrogen and potassium fertilizers should be divided into base fertilizer and three top dressings. The phosphate fertilizer should be used as the base fertilizer, and the fertilizer and farmyard manure (or commercial organic fertilizer) should be mixed.
Base fertilizer: 2500-3000 kg of farmyard manure or 350-400 kg of commercial organic fertilizer per acre, 6 kg of urea, 13-17 kg of diammonium phosphate, 7-8 kg of potassium sulfate, and 0.5 kg of borax. Topdressing: 10-11 kg of urea and 5-6 kg of potassium sulfate in the rose period; the initial application of the flower bulb is 13-15 kg of urea and 6-8 kg of potassium sulfate, and the flower bulb forms a medium-term application of urea 10-11 kg. Potassium sulfate 5 to 6 kg. Top dressing: The boron deficiency in the soil can be sprayed with 0.1% to 0.2% borax solution in the initial and middle leaves of the flower bulb, and the soil magnesium deficiency can be sprayed with 0.2% to 0.4% magnesium sulfate solution 1 or 2 times.
