Within one week after the melon planting, the temperature and humidity in the greenhouse were recorded and analyzed by the temperature and humidity self-recording instrument to take corresponding measures. Closed greenhouses are warmed and tempered. Ventilation is required when the temperature of the greenhouse exceeds 30°C. The temperature of the greenhouse is maintained at 25 ± -300°C during the day and 15 ± 18°C ​​during the night. Every day, the ventilation and dehumidification are carried out during the growth period. In order to increase the temperature of the shed, it is necessary to increase the ventilation volume, increase the temperature difference between day and night, and put a small breeze in the downstream of the wind in order to exclude harmful gases and moisture in the shed, prevent the occurrence of leggy and disease, and spread the wind in the greenhouse in the Zone II. At this time, we must pay attention to the early spring breeze, especially in recent years, sandstorms in 3 } - 4 months often affect our province, we must pay attention to the shelter, prevent the wind rip off the film, we must always listen to the weather forecast, to prevent the cold current invasion, if necessary, can take temporary Warming measures.
Melon hi light, we must pay attention to keep the film surface clean, try to use non-drip film, in order to increase the amount of light transmission, enhance light. At the same time frequent pruning, to prevent field cover.
After monitoring and regulating the temperature and humidity in the greenhouse, it is still necessary to effectively control the diseases and insect pests of the wax gourd in the greenhouse. Papaya melon pest is lighter, as long as we pay attention to strengthen ventilation and water and fertilizer management, so that the greenhouse temperature and humidity suitable, fungal diseases can be effectively controlled, the virus can be used virus A, virus soil 600} -80C times liquid spray; white powder The disease can be sprayed with 20% triterpenoid (triadimefon) EC 2000 times. 2 months after planting, winter melons grow to 1~2kg with 6~7 maturity and can be listed. When picking, take care not to injure the melons or hurt the melons.
Temperature and humidity self-recording instrument control temperature and humidity of greenhouse melon planting
Melon as a dietetic health vegetable has been widely loved by people. However, because of the seasonal influence factors, wax gourd generally needs to be available for marketing until July and August each year. If the cultivation of wax gourd is willing to adopt greenhouse cultivation, then the time for the marketing of wax gourd can be advanced, and the yield will be high, and the yield of mu will be further improved. When greenhouses grow wax gourd, they use low temperature resistance, low light and moisture resistance, and the first female flower has low node, easy fruit setting and short internodes. The early and mid-maturing varieties have strong disease resistance, strong growth vigor and good commodity performance. However, the temperature and humidity in the greenhouse need to be controlled and controlled by the temperature and humidity autograph to make the environment in the best condition for melon growth.
