玉米是黑龙江省友谊县红兴隆地区的主要农作物之一,北种玉1号是红兴隆地区的玉米主栽品种。在玉米种植中,不同播种期对其生长发育和最终产量影响极大。基于此,本研究以北种玉1号为试验试材,分5个播种期播种,探究不同播种期对北种玉1号产量的影响,以确定该地北种玉1号的最佳播期,为实现玉米高产提供理论依据。研究结果表明,北种玉1号在适宜播种期内(5月中旬左右)产量达到最大,过早或过晚播种产量均有所降低。
Corn is one of the main crops in Hongxinglong District, Youyi County, Heilongjiang Province. Beizhongyu 1 is the main corn variety in Hongxinglong area. In corn planting, different sowing dates have a great influence on their growth and final yield. Based on this, we studied the effect of different sowing dates on the yield of Beixuyu 1 to study the effect of different sowing dates on the yield of Beizhongyu 1 in order to determine the best sowing of Beixuyu 1 Period, to provide a theoretical basis for high yield of corn. The results showed that the yield of Beizhongyu 1 reached the maximum during the appropriate sowing period (around mid-May), and the sowing yield decreased too early or too late.
