How to prevent and cure cucumber in greenhouse? What is the cause of cucumber turning into melons? Please also ask the netizens who know to help introduce cucumber melons, mainly because of the discomfort of the external environment or poor technical management, which often cause the phenomenon of cucumber melons, so the farming network has sorted out the causes and solutions of cucumber melons, which are listed in detail below for netizens' reference. First, the melon caused by high temperature: when the temperature is higher than 320C in the day and more than 180C at night, the photosynthesis of cucumber will be blocked, the respiration will be significantly enhanced, the melon will turn into melon because of malnutrition, and the higher temperature will also affect the differentiation of female flowers. prone to malformed melons. Solution: strengthen the temperature control and management to provide a suitable temperature for cucumber growth. The indoor temperature (greenhouse) is controlled at 20-250C in the daytime and 12-160C at night. Second, the melon caused by low temperature: in the cold winter season, when there is continuous rainy, foggy and snowy weather, the ground temperature drops, and the absorption capacity of cucumber roots decreases greatly due to the decrease of temperature, resulting in insufficient supply of plant nutrients. Solution: to increase the temperature and restore the vitality of cucumber root system, those with heating facilities can be heated in the greenhouse to increase the air temperature and ground temperature in the shed, and the insulation materials such as grass curtains or grass curtains should be covered at night to improve the heat preservation in the shed. Third, melon caused by diseases and insect pests: in greenhouse production, diseases such as cucumber downy mildew, bacterial angular spot and powdery mildew are often encountered to harm cucumber leaves, weakening the function of producing nutrients in cucumber leaves; aphids, whitefly and other pests also harm plants and leaves, which affect the normal photosynthesis of cucumber leaves and lead to insufficient nutrient supply. Solution: when diseases and insect pests are found, prevention and control should be carried out in time. Fourth, improper fertilizer and water management causes melons: in the peak period of melon, cucumbers have a greater demand for water and fertilizer, such as insufficient supply of fertilizer and water, reduction of photosynthates, can also cause melons, in addition, excessive application of nitrogen fertilizer will also cause melon vine growth and lead to melons. Solution: to ensure an adequate supply of water and fertilizer, fertilize with water in the peak period of melon, combine farm manure with chemical fertilizer, apply biogas liquid with water flushing, pay attention to appropriate application of phosphorus and potassium fertilizer, supplement zinc, boron and other trace elements to enhance the resistance of plants.
