摘要
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 60 000 plants·hm.-2;At the same time,maize production increased with the the increasing of nitrogen fertilization,but more than 300 kg·hm.-2 of nitrogen fertilizer caused production decline.Therefore,it was recommended that suitable planting density was 60 000 plants·hm.-2 the optimum nitrogen fertilization application was 300 kg·hm.-2 for Xingyu 1 in Xing′an League.关键词
