高氮肥对寒地水稻产量和群体形态的影响
Effect of High-nitrogen Fertilizer on Yield and Group Morphology of Rice in Cold Region
摘要
Abstract
The changes of yield and group morphology were researched through experiments of different high-nitrogen fertilizer to provide technical solution for the high-yielding rice production in cold region.The results showed that urea fertilizer was 362.5 kg·hm-2,the yields of Longjing 18 and Longjing 20 reached maximum yields（11 407.41 and 9 710.24 kg·hm-2）.Urea fertilizer was 400 kg·hm-2,the yield of Longjing 14 was 9 246.19 kg·hm-2,and the effect of increasing yield was obvious in each treatment area.Increasing N fertilizer wasn＇t significant impact on panicle length and flag leaf length.Average grain number per panicle had a significant increasing trend as increasing N application,while seed setting rate significant decreased on the highest amount of N fertilizer application.关键词
