Prevention of acute dead seedlings in greenhouses

Where greenhouse insulation is used, acute cucumber atrophy occurs to varying degrees every year. The following measures should be taken for early prevention.

Timely watering

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 watering due to seedlings, less water in planting, and pouring back to seedlings. Low temperatures, high soil moisture, and even rainy weather, little or no water is returned. Into the fruit of the melon period, combined with topdressing, water with fertilizer, pouring every 10 days or so, to prevent excessive application of a fertilizer and burning 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.

Reasonably control the temperature in the shed

The initial period of colonization is generally not ventilated. The shed is maintained at 25°C to 30°C during the day and 12°C to 15°C at night, and must not be lower than 10°C. With the growth of melon seedlings, it is necessary to timely regulate air temperature to prevent diseases and avoid plant aging. Timely supplement of carbon dioxide. The regulation of temperature must be conducive to the growth of cucumbers. Generally, the temperature during daytime air temperature rises to 30°C, and in the afternoon when the temperature drops to 28°C, the film is closed. The temperature should not fall below 12°C during the result.

Strengthening shed repair

Regularly drain the drainage ditch around the cucumber planted in the greenhouse to ensure smooth flow, so that drainage can be performed 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.

Short Tubes For Urine Bag Connection

Short tubes connected or welded between urine bag and urine bag valve (such as cross valve, push/pull valve, lever valve, sampling valves, T valve) are urine bag parts, which is usually give urine bag and valve a good connection, so as to realize a nice function performance.

Urine bag are personal home or healthcare consumables, Huali's product are medical grade PVC, which is better for liquid control or management.
