摘要
Abstract
We applied nitrogen fertilizer to the spring wheat cultivar Liaochun 18 during the the three-leaf stage,the jointing stage and booting stage,and studied the effect of nitrogen fertilizer on the agronomic traits and yield of Liaochun 18.The result indicated the application of nitrogen fertilizer in the jointing stage signifi-cantly increased plant height,the number of spike grains,weight of one thousand grains and spike grains.The application of nitrogen fertilizer in the three-leaf stage made wheat panicles number reach the maximum level. Besides,we can get the result that highest yield was obtained in the jointing stage with nitrogen nitrogen fertil-izer application,followed by booting stage,and the yield in the three-leaf stage was lowest.关键词
