播期和气象条件对浚单玉米系列品种生长发育及产量的影响研究
Effect of Sowing Date and Meteorological Condition on Growth and Yield of Xundan Maize Varieties
摘要
Abstract
[Objective] Climate adaptability of Xundan maize varieties was studied in Huanhuihai summer maize planting area .[Method] Four cultivars of Xundan maize varieties were selected to investigate the effects of different sowing day and meteorological condition on the growth and yield of this series .[ Result] Growth period of each cultivar was shortened with the delay of sowing date.For ten days delay, the growth period was shortened 6.5 days.This may be related to temperature rising.For sowing date delayed, the ear length ,ear diameter, stem diameter and yield were decline.The yield of Xundan 509 and Xundan 29 were higher than those of the other two cultivars.The accumulation temperature and the sunlight had the greatest effect on yield.It was very obvious after spinning .[Conclusion]The sowing date in Huanghua-ihai area should be early after wheat harvesting.关键词
