1. Properly sparse. The cucumbers in the greenhouse should be sparsely planted and the management of fertilizer and water 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. 2 timely watering. Watering should be controlled between the two to promote the middle, that is, before the melon period, to raise the soil temperature to ensure that the soil to ensure that the wet see dry; melon period once every 7-10 days pouring water, each watering should be picked The melons are carried out beforehand to control the madness; after the harvesting of the top melon, watering is controlled and new roots are promoted. When watering back, it will be watered in time. 3. Reasonable fertilizer. On the premise of ensuring the supply of soil nitrogen, appropriate application of phosphorus and potassium fertilizer. Top dressing with red form, with water with fertilizer. Generally before the roots melon vinegar 15-20 kg before swelling, potassium sulfate 10 kg, 15 kg of diammonium phosphate, after each received two times to recover a fertilizer. In the middle and late stage, water-soluble fertilizer was applied 2-3 times. 4. Control the temperature. 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, and it is easy to grow wild. 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. 5. Control humidity. The suitable air humidity for cucumber growth and development is 60%-80%. When the humidity in the booth exceeds 85%, it should be immediately ventilated and vented; in the evening, when the temperature is between 10°C and 15°C, it should be ventilated for 1-2 hours to reduce nighttime temperature and humidity, prevent madness, control diseases, and promote flowering and fruiting. 6. Look to tie the vines. The vine spreads when it reaches about 30 centimeters. 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. 7. Hormones protect melons. After the cucumber is coated, the vegetative growth of the plant is controlled. Therefore, it is necessary to try to make the first batch of flower more sitting. If the first batch of flowers sitting less, easily lead to crazy. Can be used to protect the fruit 100 times liquid flower or spray flowers, cucumber can sit more and melon, and can keep melon, and promote rapid expansion of small melon. It can mention the morning market, increase the early production, and effectively prevent melons from going mad. 8. Look at what you are collecting. Root melon has a significant effect on melons. When root melons are harvested later, the growth of melons is inhibited. Crab larvae should be properly picked root melons in order to play a role in falling cicadas, to ease the madness; melon quails grow weak, we must early harvest root melons, to prevent falling cicadas, as soon as possible to take measures to promote growth.
