播种期的选择对玉米产量的影响

Effects of Sowing Time Selection on Maize Yield

从播种期对光照、温度、降雨量和风的利用入手,探讨了播期对玉米产量的影响,以便更深刻地了解播期、气候资源和玉米产量之间的关系。结果表明,适时播种可促成玉米的增产增收。在一定的气候条件下,通过播期调整玉米与气候条件的配置,可以有效调控玉米的生长发育,进而调控产量形成。在播期的选择上不应仅考虑温、光因子,还要重视降水等其他气候条件。

Starting from the utilization of illumination, temperature, precipitation and wind in sowing period, effects of sowing date on maize yield were discussed in order to deeply understand relationship among sowing date, climatic resources and maize yield. As indicated by the re- suits, sowing at proper time could promote yield increasing of maize. Under the certain climatic conditions, through adjusting maize and climatic conditions allocation in sowing period could effectively regulate growth and development of maize, as well as yield formation. On selecting sowing period should not only consider temperature and light factors, but also pay more attention to climatic conditions.
