15-20 days before sowing preparation before sowing, deep plowing and tilling, combined with cultivating 3,000-4,000 kg per acre of cooked manure, with SF compound fertilizer 15 kg-20 kg. After drying in the fields for 7-10 days, seal the sheds for 5-7 days and fully sterilize the soil and temperature sheds through sunlight and high-temperature stuffy sheds. After the ground is leveled, reserve the open space on the east side of the temperature shed, build a loquat width of 1.1-1.3 meters, prepare the seedbed, and then ridicule along the north-south direction, 10 centimeters high and 90 centimeters wide, covering the mulch to ensure warming. The seeds of the bitter gourd seeds are hard and hard, and must be soaked before sowing.
