| 摘 要： | 通过开封市蜜瓜生育期间的光温水等气候条件的分析：开封市常年平均气温基本都处在其适宜生长范围内，总体热量条件能够满足蜜瓜不同发育期的需求。蜜瓜从播种发芽到果实成熟期，开封市各级降水日数逐渐增多，前三个发育期内的降水日数明显少于果实成熟期，环境空气湿度较低，对于蜜瓜生长发育有利，但要注意预防由于降水极端偏少而引发的干旱缺水。蜜瓜成熟期要及时根据降水实况和农田土壤状况，采取控制浇水、加强排水等措施，促进蜜瓜果实产量和品质的提高。开封市蜜瓜生育期间的光照强度呈现明显上升趋势，光照资源基本可以满足蜜瓜不同生长发育的需求。蜜瓜伸蔓期正好于开封市光照资源最为丰富的时期相重合，对蜜瓜的旺盛生长十分有利的。果实成熟期，开封市温高光强，有利于蜜瓜产量和品质的提高。

| Abstract: | Through the analysis of climatic conditions such as light, temperature and water during the growth of honeydew melons in Kaifeng, Kaifeng''s annual average temperature is basically within its suitable growth range, and the overall thermal conditions can meet the needs of honeydew melons at different growth stages. The number of rainy days at all levels of Kaifeng gradually increased from seeding germination to fruit ripening. The number of rainy days in the first three development periods was significantly less than that during the fruit ripening period. The ambient air humidity is low, which is beneficial to the growth and development of honeydew melons. A attention shouid be Paid to prevent drought and water shortage caused by extreme low precipitation. During the ripening period of honeydew, it is necessary to take measures such as controlling watering and strengthening drainage according to the actual rainfall and soil conditions of the farmland in time to promote the improvement of the yield and quality of honeydew fruit. The light intensity during the growth period of honeydew melons in Kaifeng showed an obvious upward trend, and the light resources can basically meet the needs of different growth and development of honeydew melons. The vine-stretching period of the honeydew coincides with the period when the light resources are the most abundant in Kaifeng, which is very beneficial to the vigorous growth of the honeydew. During the fruit maturity period, the high temperature and light intensity in Kaifeng are beneficial to the improvement of the yield and quality of honeydew melon. ; |
