摘要
采取分期播种方法研究不同播期对秋种水果玉米产量的影响。结果表明,对秋种水果玉米生育期和产量发挥着主导作用的气象因子为平均温度、积温以及日照时数。不同播期气象条件中的平均气温和总日照时数的波动对秋种水果玉米百粒重、产量的影响较大。在福州地区秋种水果玉米播期越早越佳,应尽量避免9月下旬以后播种。
In this paper,the effect of different sowing dates on the yield of autumn fruit maize was studied by sowing by stages.The results showed that the dominant meteorological factors affecting the growth period and yield of autumn fruit maize were average temperature,accumulated temperature and sunshine hours.The fluctuation of average temperature and total sunshine hours in different sowing dates had great influence on 100 grain weight and yield of autumn fruit maize.In Fuzhou area,the earlier the sowing date of autumn fruit corn is,the effect is better.Local should try to avoid sowing after late September.
