Detailed Explanation of Management Techniques Before and After Transplanting Broccoli

Before transplanting, apply high-quality farmyard manure per mu, mix evenly with 10 kg of ammonium nitrate, plow, harrow fine and level, then form ridges and transplant in wide-narrow rows of 70 plus 50 cm, that is, ridge surface width 70 cm, furrow width 50 cm, cover the ridge surface with 90 cm plastic film, plant spacing 40 cm, and maintain 2750 seedlings per mu.

After transplanting, apply both fertilizer and water together, focusing on promoting growth, keep the temperature at 8°C-24°C, and spraying 600——800 times diluted Xin Gao Zhi Mo can effectively prevent aboveground moisture from evaporating, prevent moisture in the seedling body from transpiring, isolate pests and diseases, shorten the seedling recovery period, quickly adapt to the new environment, and grow healthily. After about 10 days, apply 15 kg of ammonium nitrate along with watering, apply 6 kg of ammonium nitrate before the top curd appears, and after the curd appears keep the temperature at 15°C-18°C; below 8°C, the curd grows slowly, and above 24°C, the curd becomes loose; during the whole plant growth period, the temperature should not exceed 32°C.
