通过样品扫描，采用ＤＴ－ＳＣＡＮ 图形分析软件对麦套棉生态系统的小麦根系生长发育进行分析测定。结果表明，边行、中间行的根长密度峰值比空白行根长密度峰值提前６～７ ｄ 出现，边行在孕穗期根长密度的峰值＞ 中间行的根长密度峰值＞ 空白地的根长密度峰值。整个小麦生育期根系主要分布在０～３０ ｃｍ 范围，根系直径的分布、边行、中间行的直径变化规律基本一致，０～１０ ｃｍ 变化较大，２０～１００ ｃｍ 变化基本平稳，而空白地根直径在４０～６０ ｃｍ 变化较大，上层、下层较小。从各种参数比较，充分说明了边行根系的优势与地上部分的边行优势是一致的。
Through the sample scanning, using DT-SCAN graphical analysis software wheat wheat cotton wheat growth and development of wheat ecosystem analysis and determination. The results showed that the peak root length density of the middle row and middle row appeared 6 ~ 7 days earlier than that of the blank row. The peak of the root length density at the booting stage> the peak root length density at the middle row> the root at the blank Long-density peak. The root distribution of the whole wheat was mainly distributed in the range of 0-30 cm. The distribution of root diameter, the diameter of the middle row and the middle row were basically the same, the changes of 0-10 cm were larger, the changes of 20-100 cm were basically stable, The root diameter varies greatly from 40 to 60 cm, and the upper and lower layers are smaller. Comparing various parameters, it fully shows that the superiority of the side-line root system is consistent with that of the above-ground part.
