Open-field sowing methods and technical key points for melons
Open-field melon sowing method: open-field melons are grown using plastic film mulching with a water-and-dry bed system. Generally, the water bed is 0.5 m wide, the dry bed is 1.5-1.8 m, and the furrow is 20 cm deep. A north-south orientation of the beds is best. Before forming the ridges, open a small furrow (8-10 cm) with a small plow on both sides of the dry bed at 30 cm from the ridge edge line and apply organic fertilizer. The ridge height is 20 cm, the top opening of the water furrow is about 50 cm wide, and the depth is...
Open-field melon sowing method: open-field melons are grown using plastic film mulching with a water-and-dry bed system. Generally, the water bed is 0.5 m wide, the dry bed is 1.5-1.8 m, and the furrow is 20 cm deep. A north-south orientation of the beds is best. Before forming the ridges, open a small furrow (8-10 cm) with a small plow on both sides of the dry bed at 30 cm from the ridge edge line and apply organic fertilizer. The ridge height is 20 cm, the top opening of the water furrow is about 50 cm wide, and the depth is 40-50 cm. Level and harrow the bed surface thoroughly. Fertilization should be based mainly on organic fertilizer, with a moderate amount of chemical fertilizer, balanced fertilization, and controlled use of nitrogen fertilizer. The nitrogen-phosphorus-potassium ratio is 1:2:1. Before sowing, apply 4000-6000 kg of organic fertilizer, 20-30 kg of diammonium phosphate, 10 kg of urea, and 10-15 kg of potassium sulfate per mu. Use the direct sowing method. First dig holes at the sowing positions, 6-8 cm deep, sow 2-3 seeds per hole, with a plant spacing of 0.5-0.4 m, cover with 1-1.5 cm of soil, and then cover with plastic film 90 cm wide, or cover with film first and then sow.
