First, scientific application of fertilizer water.

After the root melon is harvested, combined with watering, the fertilizer is applied once in a timely manner. After the autumn cucumber enters the melon period, water is usually poured once every 3-4 days. Take small water and water to avoid flooding. In this way, it can achieve drought, no stagnation, less pests and diseases, and can often cool down and improve the microclimate in the field. Usually, the water is poured once every time, and the fertilizer is chased once. The use of urea is 15-20 kg, and it is suitable to apply quick-acting phosphorus and potassium fertilizer, which has a good yield increasing effect. In case of heavy rain, pay attention to drainage. After each heavy rain, combine shallow weeding once. After entering the squash period in late August, no more cultivating and weeding. It is usually harvested once every 1-2 days.

Second, pay attention to cold and warm. The farmer said: A burst of autumn winds, a burst of white frost. In September, it is in the solar terms of “Bailu” and “Autumn”. The weather turns from hot to cool, and the temperature is cool at night, and the temperature is cool, so it is necessary to strengthen warmth and cold. In early September, the autumn cucumber is still in the stagnation period, and a wind barrier is set up in the cucumber field, and a barrier is set up on the north side and the west side to reduce the invasion of the white wind and prevent the plant from premature aging. At the same time, spraying 0.5% potassium dihydrogen phosphate foliar fertilizer can prolong the harvest period and increase the later yield. In the middle and late September of September, the cucumber entered the late stage of melon, and the number of watering was reduced accordingly.

Third, timely prevention of pests and diseases. Cucumber downy mildew can be used for prevention and treatment of 58% metalaxyl manganese zinc 500 times, Du Jie Kelu 600 times, 64% anti-virus 矾 800 times, 75% chlorothalonil. Insect pests mainly include greenhouse whitefly, aphids, spotted fly, and sassafras. It can be used with Akthai 5000 times liquid plus Kungfu Kid Oil 2000 times to 3000 times. Spraying once every 7 days can achieve the control effect.
