摘  要:
研究了高产超高产条件下,不同生育时期镇压对小麦生长发育的影响。结果表明:镇压可增加单株次生根数,降低株高,尤其是基部第1 ,2 ,3 节间总长度缩短;可推迟幼穗发育,提高小穗结实率,增加穗粒数。镇压后分蘖对低温反应敏感,温度回升后分蘖增加较快。以单棱期镇压效果较好,二棱期( 初期、末期) 镇压效果较差。

Winter wheat Rolling Growth duration
摘  要:
Effects of rolling at different growth duration were studied on winter wheat growth and development under the high yield and supper high yield conditions were studied.The result showed that rolling could increase secondary roots per plant,decrease plant height,shorten total length of basal internode 1,2 and 3,delay young ear development and improve fertile percentage of spikelets and then increase kernels.The whole trend of effects of rolling on tiller was that tiller was sensitive to low temperature and enhanced quickly when temperature rose.Among all treatments of rolling at different periods,rolling the effect on yield factors at the single ridge period were harmonious and that at double ridge period was lower.
