骆驼刺幼苗生长特性对不同地下水埋深的响应

, 2009
在塔克拉玛干沙漠南缘策勒绿洲,对人工控制地下水埋深条件下的骆驼刺幼苗地上和地下部分的生长特性进行了一个生长季的调查。结果表明:1)幼苗的株高、分枝数、冠幅与不同地下水埋深之间存在较好的相关性,不同地下水埋深下幼苗叶片数的波动较大;2)生长在距地下水埋深为2.5和2.0m及1.5和1.0m条件下的骆驼刺幼苗的基径变化没有显著差异(P>0.05);3)地下水埋深对骆驼刺幼苗根系的垂直根长的影响显著 ...

土壤-根系界面水分调控措施对冬小麦根系和产量的影响

, 2002
以冬小麦田间试验为基础 ,研究根 -土界面不同水分调控措施 ,包括不同深度灌水 (地面、30 cm、5 0 cm、1 0 0 cm )、同一深度保持不同田间持水量 (田持 80 %、6 5 %、5 0 % ) ,共计 1 2个水分处理的土壤水分分布对根系和产量影响。研究表明 :根长密度分布与灌水方式息息相关 ,地面灌水的根长密度随土层深度呈指数下降趋势 ,主要分布于地表层 ( 0～ 1 0 cm ) ;不同深度渗灌 ,根系分布有两个峰值 ,第 1峰值分布在地表以下 1 5 cm左右 ,第 ...
