First of all, we must remove the greenhouse debris and plow the sun in advance. Soil preparation before planting, and adequate base fertilizer, adhere to the main organic fertilizer, nitrogen, phosphorus, potassium, trace fertilizer combined application. Generally, 6,000 kg of high quality farmyard fertilizer, 20 kg of ammonium phosphate, and 25 kg of potassium sulfate can be applied fully to each acre. For new greenhouses, the amount of soil organic matter below 2% can be increased as appropriate.
After the land is well-grounded, the ridges are ditched along the north-south line, covered with large and small sorghum mulch, and irrigated by under-membrane or under-drip irrigation. Large row spacing 80 cm, small row spacing 40 cm, ridge height 20 to 25 cm.
Colonization should be selected in the sunny morning, according to the spacing of 30 cm in the car on both sides of the "product" shape double row open hole, pouring stable seedling water, side planting seedlings, side cover soil sealing points, the surface should be higher than the car (ridge) surface 2 cm. When planting, pay attention to mulch, do not contaminate the graft interface. 3000~3500 strains per acre.
The temperature during daytime of seedlings was controlled at 25°C~30°C and nighttime at 18°C~20°C. The temperature was controlled at 20°C~25°C and 12°C~15°C at night during the day when the seedlings were regenerated, and watering was appropriately controlled.
