To prevent the madness of the cucumbers in the greenhouse, we adopt the following technical measures: 1, rational close planting. The cucumber in the greenhouse should be properly planted and the fertilizer and water management should be strengthened. The density of colonization should be determined according to species, soil strength, and season. Generally, 4000 to 4500 plants are planted per acre. 2, a reasonable fertilizer. On the premise of ensuring the supply of soil nitrogen, appropriate application of phosphorus and potassium fertilizer. Top dressing is in liquid form, with water as fertilizer. Generally before the root melon vinegar recovery after 15 to 20 kg, 10 kg of potassium sulfate, 15 kg of diammonium phosphate, after every two melons to recover a fat. In the middle and late period, the water is used to recover and dilute the manure for 2 to 3 times, each time about 1,000 kilograms per mu. 3, timely watering. Watering to control the middle of the two before the melon period before, in order to raise the temperature of the soil to protect the soil, do see the wet see dry; melon period every 7 to 10 days pouring 1 water, each watering should be in the pick melon Before proceeding, to control its madness; control the watering after harvesting the top melon and promote the growth of new roots. When watering back, it will be watered in time. 4, control the temperature and humidity. The suitable temperature for the growth and development of cucumber is 25°C～30°C, and the growth of plants is faster than 30°C. Therefore, the temperature of the greenhouse should be maintained at 25°C to 30°C during the day and 18°C ​​at night. The suitable air humidity for cucumber growth and development is 60% to 80%. When the humidity in the booth exceeds 85%, it should be immediately ventilated and dehumidified; when the temperature is 10°C-15°C in the evening, it should be ventilated for 1 to 2 hours to reduce the humidity at night. 5. Look at the vines. When the melons grow to 30 centimeters, they begin to bind the vines. For the first time, when the vines grow vigorously, they can bend and abdomen, and the degree of bending and tightness depends on the growth of guaguan. If there is a small amount of melons, the degree of bending must be large and it must be tight. 6, hormones to preserve melon. After cucurbit cucumber, the vegetative growth of the plant was controlled. Therefore, it is necessary to try to make the first batch of flowers more sitting. If the first batch of flowers sitting less, easily lead to crazy. The use of Paulownin hormone 100 times liquid dip, spray flowers, cucumbers can sit more and melon, and can keep melons, prompt small melon rapid expansion. It can not only mention the morning market, increase early production, but also effectively prevent melons from going mad.
