摘要
根据中玉糯二号鲜食玉米品种的分期播种试验观测资料 ,分析了不同播期和温度因素对鲜食玉米生育速度、产量的影响规律 ,提出鲜食玉米栽培鲜果穗安全灌浆的平均最晚播期为 8月 10日 ,具有 80 %气候保证率的播种期为 8月 6日 ,并在此基础上讨论了鲜食玉米一年三熟栽培的季节安排。
According to the observations in sowing date experiments of fresh cooking maize variety“Zhongyunuo”No.2, the regular effects of different sowing dates and temperature factors on maize growth speed and yield were analysed. It was suggested that the average latest sowing date ensuring safe filling of maize ears is 10 August and the sowing date leading to 80% climatic guarantee degree is 6 August. On the basis of above analyses ,the arrangement of cropping seasons of fresh cooking maize under three crop a year system was further discussed.
