| 摘 要： | 为探讨扬农啤5号高产的最佳基本苗,研究调查分析了扬农啤5号4个不同基本苗的茎蘖动态、产量性状的差异.结果表明:基本苗对生育前期茎蘖动态有一定的差距,但返青拔节后差距进一步缩小,成穗数相差较小,产量差异不显著.对扬农啤5号而言,适当降低基本苗、促进个体生长,在确保一定穗数的前提下,争取大穗大粒是进一步提高扬农啤5号的有效途径.

| Abstract: | To explore the best planting density for high yield on barley Yangnongpi 5.The difference of tiller dynamics and characters of yield were investigated on four different planting density of Yangnongpi 5.The results showed: the gap of the tiller dynamics were existed for planting density on the earth of plant growth,but the difference were reduced after turning green and jointing stage.The difference of spike rate and yield among four planting density were smaller and not significant.So the appropriate planti... |
