To prevent greenhouse growers in greenhouses mainly take the following measures: Closely planting cucumbers in greenhouses should be appropriately sparsely planted, and fertilizer and water management should be strengthened. The density of colonization should be determined according to species, soil strength, and season. Generally, 4000-4500 plants are planted per acre. Timely watering to control the middle of the two to promote the middle, that is before the melon period, mainly to increase the temperature of the soil to protect the soil, do see wet see dry; guagua period water every 7-10 days, each watering should Before picking the squash, to control the madness; control the watering after the top melon is harvested, and promote new roots. When watering back, it will be watered in time. Reasonably topdressing under the premise of ensuring the supply of nitrogen in soil, apply more phosphorus and potassium fertilizer. Top dressing is in liquid form, with water as fertilizer. Generally before the root melon before harvesting 15-20 kg of urea, 10 kg of potassium sulfate, 15 kg of ammonium phosphate, after each received two times to recover a fertilizer. In the middle and later stages, the water is used to chase the cooked manure 2-3 times, each time about 1,000 kilograms per mu. The suitable temperature for controlling the growth and development of cucumber is 25°C-30°C. If the growth of plants is faster than 30°C, it is prone to growth. Therefore, the temperature of the greenhouse should be controlled at 25°C-30°C during the day and should not exceed 30°C. The nighttime temperature should be maintained at about 18°C ​​to reduce the respiration and increase the accumulation of dry matter. Control Humidity The appropriate air humidity for cucumber growth and development is 60%-80%. When the humidity in the booth exceeds 85%, it should be immediately ventilated and ventilated; in the evening, when the temperature is between 10°C and 15°C, it should be ventilated for 1-2 hours to reduce the nighttime temperature and humidity, prevent madness, control diseases, and promote flowering and fruiting. When you see the vines grow to about 30 centimeters, they begin to bind vines. When the vines grew vigorously for the first time, the vines could be bent and abducted around. The degree of bending and tightness depended on the growth of the guaguana. If there is a small amount of melons, the degree of bending must be large and it must be tight. The vegetative growth of the plants is controlled after the hormone protects the cucumbers and melons. 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. According to the experiment, using 100% liquid of Paulowning hormone to dip the flowers and spray flowers, the cucumbers can sit on melons, and they can keep the melons and promote the rapid expansion of the melons. It can not only mention the morning market, increase early production, but also effectively prevent melons from going crazy. Seeing pods and melon pods has a significant effect on melon pods. When root melons are harvested later, the growth of melon pods is inhibited. Crab larvae should be properly picked root melons in order to play the role of falling maggots, to ease the crazy growth, when the melon cricket growth is weak, to early harvest root melons, to prevent falling, as soon as possible to take measures to promote growth.
