| 摘 要： | 以膜下滴灌条件下棉花根系为对象,通过根钻取样的方法,探索棉花根系的分布规律,研究了膜下滴灌条件下棉花根系的分布特性。结果表明:棉花根系主要分布在0~40 cm的土层中;随着深度及水平距离的增加,在棉花的各生育期其根重密度及所占总根量的百分数逐渐减少,并在棉花的各生育期,其根量所占总根量的百分数与水平距离及垂直距离呈负指数关系,根重密度在垂直方向上与深度也呈负指数关系。 |
| 关 键 词： | 膜下滴灌 棉花 根系分布 根系密度 |

| Abstract: | Research on the distribution peculiarity of cotton roots under the sub-film was conducted by root sampling method.Results show there are plenty of roots at the depth of forty centimeters.Furthermore,as the depth and horizontal distance increased,the roots density and percentage gradually decreased in different growing time of cotton.The root distribution and depth have negative exponent equation with horizontal distance.Vertically,root weight density and depth have negative exponent equation. |
| Keywords: | drip irrigation under mulched cotton root distribution root density |
