摘要
[目的]在中等肥力大田条件下，研究不同播期和施氮量对俊达001产量及农艺性状的影响。[方法]以玉米品种俊达001为试验材料，研究4个施氮量（225、375、525、675 kg／hm2）和3个播期（6月2日、6月10日、6月18日）对其农艺性状和产量的影响。[结果]在种植密度67500株／hm2条件下，俊达001高产的最适施氮量为525 kg／hm2，最适播种期为6月2日。[结论]该研究探索出俊达001高产的最佳播期和施氮量，为其高产稳产提供参考。
Abstract
Objective] To study the effects of sowing date and quantity of applied nitrogen on the yield and agronomic characters of maize Junda 001 planted in farmland with medium fertility.[Method] The effects of various quantities of applied nitrogen (225, 375, 525, and 675 kg/hm2) and sowing dates (June 2, 10, and 18) on the yield and agronomic characters of maize Junda 001 were analyzed.[Result] When the planting density of maize Junda 001 was 67 500 plants/hm2 , the optimal quantity of applied nitrogen was 525 kg/hm2 , and the optimal sowing date was June 2.[ Conclusion] The research can provide scientific references for the high and stable yield of maize Junda 001 based on the optimal sowing date and quantity of applied nitrogen.
