I. Removal of greenhouse debris

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.

2. After the land is well-grounded, the ridges will be ditched along the north-south line, and covered with large and small sorghum mulch, under the film dark irrigation or drip irrigation under the membrane. Large row spacing 80 cm, 40 cm row spacing, ridge height 20-25 cm.

Third, the sunny morning colonization

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 Dingmiao.

IV. Management Information for Greenhouses

1. Temperature and humidity management. Seedling temperature during daytime control at 25 °C -30 °C, 18 °C -20 °C at night, after the slow seedling temperature control during the day at 20 °C -25 °C, night 12 °C -15 °C, and appropriate control of watering.

After sitting on the melon, the temperature in the morning is controlled at 25°C-30°C, the maximum is not more than 33°C, the humidity is about 75%; in the afternoon 20°C-25°C, the humidity is about 70%; the minimum temperature at night is above 12°C.

2. Lighting management. Greenhouses should be made of light-free, non-drip films, and often clean the membrane surface to keep the plastic film clean. During the daytime, the intensity and time of light should be increased as much as possible. Even in cloudy snow days, the straw curtains on the shed must be removed, and the heavy snow days can be used to remove the straw curtains at short noon after cleaning the snow. If the time is long and cloudy, clear the curtains and gradually increase the light.

3. Water and fertilizer management. After easing the seedlings, the water should be properly controlled and the roots should be controlled before sitting on the roots. Root melons sit and pour melon water, combined with water to apply melon fertilizer. Later, depending on the soil, weather, and seedlings, the water should be poured once every 10 to 20 days. Membrane pipetting methods should be used. Watering should be selected on a sunny morning, and attention should be paid to the release of moisture. Every time the water is poured 2 to 3 times to recover fertilizer, the fertilizer is stopped 30 days before harvest.

V. Plants adjust in time

When the plant height is about 25 centimeters, it starts to hang the vines with plastic ropes. In the future, it must be circumvented once every 3-5 days. When the vines are around, the "leading" should be kept in a plane. Timely removal of tendrils and malformed melons. When female flowers are too much, they should be sparsely flowered. Usually leave 1-2 melons per section. When the plant growth point reaches a height of 1.7-1.8 meters, it is covered with vines in the sunny afternoon and the diseased leaves and old leaves are promptly removed.
