Title: Study of Different Nitrogen Level on Rice Growth at Cold Area
Abstract: The effect of different nitrogen levels on rice yield and quality of Longdao No.5 and Dongnong 428 through single factors experimental design.The result showed that the growing period of rice was delayed with the nitrogen level increased,effective tillers was increased,but excessive nitrogen fertilizer led to ineffective tillers also increased,the differences were significant by different nitrogen levels effect on rice panicle per square meters,grains per spike,air shriveled grain,1000-grain weight and yield.The panicle per square meters of Longdao No.5 was increased with the increasing of nitrogen.During the nitrogen level 0~135 kg·hm-2,the number of grains per spike,1000-grain weight and yield was increased with the amount of nitrogen increasing,while nitrogen level in 175 kg·hm-2 the number of grains per spike was declined and air shriveled grain was high,Dongnong 428 had the same trend.
