摘要
油菜生长很大程度受气象条件的限制,生育进程依据气象条件的变化,会出现提早或推迟的现象。分析了2012—2013年南京市高淳区油菜生长期间≥0℃积温、降水量、日照时数等气象因子与该年油菜生长发育的关系,得出油菜各个生育阶段有利有弊的农业气象条件及产量形成的气象条件。分析结果为南京市高淳区科学栽种油菜,并取得更高的经济效益提供了参考依据。
Rapeseed growth was largely influenced by weather conditions.The growth process of rape based on meteorological conditions change, would be early or delayed .The relationship between rapeseed growth and meteorological factors in Gaochun District in 2012-2013 was analyzed, such as ≥0℃ accumulated temperature, precipitation, sunshine hours and others. The pros and cons of the agro-meteorological conditions and weather conditions for yield formation in rapeseed various growth stages were obtained. The results provided references for scientific planting rapeseed,and getting better value in Gaochun District. Key words Rapeseed; Growth period; Agro-meteorological conditions
