摘要
为确定播期对冀东地区春玉米产量及产量性状的影响,以众信338和鑫研218两个品种为试材,设置5个播期水平,进行了播期对玉米产量及其产量性状影响的试验。结果表明,众信338在5月中下旬播种,鑫研218在4月下旬播种能够协调好各产量性状之间的关系,实现高产。
Five sowing date levels were set for two cultivars Zhongxin-338 and Xinyan-218 to determine the influences of sowing date on spring maize yield and its traits in the eastern Hebei province.The results showed that Zhongxin-338 was sown in mid-and late-May and Xinyan-218 was sown in late-April,which could coordinate the relationship between yield traits and achieve high yield.
