| 摘 要： | 在吉林省东部低温冷凉区,通过logistic方程比较覆膜和不覆膜玉米子粒灌浆过程,探讨不同种植方式对玉米子粒灌浆和产量的影响。结果表明,通过覆膜可有效提高地温,促进玉米生育进程,提高玉米灌浆速率,延长灌浆持续时间,显著增加玉米百粒重和产量。通过覆膜,3个品种两年平均产量最高可达11 571 kg/hm~2。平均灌浆速率(R_(mean))和灌浆速率达到最大时的玉米生长量(W_(max)),与玉米百粒重和产量存在显著的正相关关系。

| Abstract: | To investigate the effects of different cultivation methods on grain filling rate and yield of maize, the logistic equation was used to compare the grain filling process of film covered and non-film covered maize kernels in the Cold climate areas of eastern Jilin Province. The results showed that film covered planting technology effectively improved the temperature of grain filling stages, promoted the growth process of maize and increased the grain filling rate. Additionally, the duration of grain filling were prolonged and the hundred-grain weight and yield were significantly increased, by film-covered,the average yield of the three varieties reached up to 11 571 kg/ha in two years. The average grout rate(Rmean) and the maize growth rate(Wmax) when the grout rate reached the maximum were significantly positively correlated with the maize hundred-grain weight and yield. |
