摘要:
为探索兴玉1号在兴安盟地区的最佳种植密度和合理的施氮量，研究了玉米新品种兴玉1号在兴安盟地区种植密度、施氮量对玉米产量的影响。结果表明：密度在60000株?hm2以内，随着种植密度的增加，玉米产量呈上升趋势，但密度超过60000株?hm2后，产量反而下降；一定密度条件下，增施氮肥，有利于玉米产量增加，但氮肥施用量要适当，施用量超过300kg?hm2会造成产量下降。因此，推荐兴玉1号在兴安盟地区的适宜种植密度是60000株?hm2，最佳施氮量为300 kg?hm2
Abstract:
In order to explore the best reasonable planting density and nitrogen fertilizer application for Xingyu 1 in Xing′an league,the effect of plant density and amount of nitrogen on the yield of Xingyu 1 was studied in Xing′an League.The results showed that the grain yield of the maize increased with the increasing of planting density,but the production decreased when the density was more than 60000 plants?hm2 ;At the same time,maize production increased with the the increasing of nitrogen fertilization,but more than 300 kg?hm2 of nitrogen fertilizer caused production decline.Therefore,it was recommended that suitable planting density was 60000 plants?hm2 the optimum nitrogen fertilization application was 300 kg?hm2 for Xingyu 1 in Xing′an League.
