北京地区夏秋茄子座果率低,不易获得高产、稳产。夏秋茄子开花时的气象因素:降雨量、空气相对湿度、日照时数等均能影响座果率,其中降雨量是最主要的因素。短花柱花型的座果率尽管远较中长花柱花型为低,但它们受气象因素影响的趋势相似。不同时期栽培的夏秋茄子,由于花期所经历的气候条件不同,其座果率也各有异,因此根据气候条件调整播种期、定植期是提高座果率、增加产量的有效措施。 Beijing summer fruit yield rate of eggplant is low, difficult to obtain high yield, stable yield. Summer and autumn when the flowering eggplant meteorological factors: rainfall, air relative humidity, sunshine hours can affect the rate of fruit set, of which rainfall is the most important factor. Although the fruit rate of short styles was much lower than that of middle styles, their tendency of being influenced by meteorological factors was similar. The summer and autumn eggplant cultivated in different periods have different fruit set rates due to different climatic conditions during flowering period. Therefore, adjusting seeding period and planting period according to climatic conditions is an effective measure to increase fruit set rate and increase yield.
