设施西瓜雌花催化的气象要素调控研究

Research on Meteorological Factor Regulation of Catalytic Activity of Female Flowers in Facility Watermelons

利用昌乐县气象局连续6年15期西瓜观测试验数据,研究对设施西瓜雌花催化影响较敏感的气象要素,同时找出雌花成功催化的适宜温度、湿度、10 cm地温和日照时数,进一步探究了设施西瓜雌花催化的气象要素调控技术。结果表明,气象要素与西瓜雌花催化有密切关联,温度对雌花催化影响最大,设施内气象要素调控在温度为19~20℃、日照时数为6~10小时、10 cm地温为18~22℃、相对湿度为57~58%时,能有效促进西瓜雌花催化,有利于解决设施西瓜雌花稀少、坐瓜难、只开花不结果等问题。Using the data of 15 consecutive watermelon observation experiments conducted by Changle County Meteorological Bureau for 6 years, this study investigates the meteorological factors that are more sensitive to the catalytic effect of female flowers in facility watermelon. At the same time, the suitable temperature, humidity, 10cm ground temperature, and sunshine hours for female flowers to successfully catalyze are identified, and further exploration is conducted on the meteorological factor regulation technology of facility watermelon female flower catalysis. The results showed that there is a close correlation between meteorological factors and the catalysis of female watermelon flowers, and temperature has the greatest impact on the catalysis of female watermelon flowers. The regulation of meteorological factors in facilities can effectively promote the catalysis of female watermelon flowers when the temperature is 19~20˚C, the sunshine hours are 6~10 hours, the 10cm ground temperature is 18~22˚C, and the relative humidity is 57~58%, which is conducive to solving the problems of sparse female watermelon flowers, difficult melon sitting, and only flowering but not bearing fruit in facilities.
