When ridged, it was carried out in a wide and narrow row. The width was 80 cm and the narrowness was 70 cm. The ridge height is 15 to 18 centimeters and it is required to be straight and straight. Between the ridges and ridges, dig a water ditches 30 cm wide and 10 cm deep and fill with water. The ridges cover the mulch to increase the ground temperature.
Timely planting, prevention of pests and diseases in the ridge on both sides of the ditch planting a row, spacing 60 cm, 30 cm spacing, 2700 cucumber per acre colonization. Apply 75% chlorothalonil once on the seedbed before lifting. After the whole shed is planted, use 20% speed hundred fumigation agent and banned fumigation agent shed fumigation once to prevent pests and diseases.
Careful management, reasonable replenishment of water and fertilizer to be about thirty centimeters when the larvae grow, it is necessary to suspend the pods in time to facilitate the rapid growth of its ventilation and light. According to the cucumber head growth point in the morning of the water spit and leaf watering, the growth point at the morning without dew or normal temperature at noon, a slight wilting of the leaves should be timely film watering. At the same time, after the female melon flower Xie, supplemented with 5 kg of urea and 5-7 kg of potassium sulfate compound fertilizer per mu, in order to facilitate the expansion of high yield. The temperature of the cucumber field in spring should be controlled at 25°C to 28°C during the day and 15°C at night. Pay attention to ventilation to prevent heat and keep the temperature difference between day and night.
