In places where greenhouses are used for cultivation, acute atrophy of cucumber occurs to varying degrees every year. The following measures should be taken for early prevention. 1. Because the seedlings are watered properly. The roots of cucumbers are more developed, but most of them focus on new roots in the soil surface. To avoid watering mistakes and inhibit the growth of root groups, pay attention to the watering of seedlings. 2. Set aside a small amount of planting water and pour water back into the seedlings. Low temperatures, high soil moisture, or even rainy weather, little or no water. Into the period of fruiting melons, combined with topdressing, with water, fertilizer, once every 10 days or so, to prevent excessive application of fertilizer once burned melon seedlings. It is better to water in sunny mornings and avoid watering in the afternoon and evening. Rainy days should not be watered in a full shed. It is necessary to dilute the water and not flood the area. 3. Reasonably control the temperature in the booth. The initial period of colonization is generally not ventilated. During the daytime shed, 25°C~30°C is maintained, and at night, it is maintained at 12°C~15°C, and is not lower than 10°C. With the growth of melon seedlings, it is necessary to timely adjust the temperature and control the temperature, its role are: to prevent the occurrence of diseases; to avoid plant aging; supplement carbon dioxide. However, the regulation of temperature must be conducive to the growth of cucumbers, generally the daytime temperature rises to 30 °C when the ventilation, the afternoon down to 28 °C when closing the film. The temperature during the squash should not fall below 12°C. 4. Regularly dredge the ditch around the cucumber planted in the greenhouse to ensure unimpeded flow, so that drainage can be done in a timely manner to achieve rapid water filtration. Every day, it is necessary to check if the shed film is damaged or leaking. Pay attention to repair and increase the temperature of the insulation. Before the advent of cool winds, cover the grass and lock the ropes to prevent the cold winds from invading the seedlings.
