栽培措施对冬小麦根系及其活力和植株性状的影响

 试验结果表明，深耕、种植密度、灌水、不同时期施肥灌水等栽培措施皆影响冬小麦的次生根数、根干重、根分布、根活力、根吸收能力及植株地上部分性状。小麦根系对环境条件或栽培技术具有适应性和“自动调节能力”。追施肥水对根系活性具有近期效应。后期根系活力（TTC还原强度）与叶片衰老指数和产量性状密切相关。

RESEARCH OF CULTIVATION METHODS ON ROOT SYSTEM ROOT VIGOR AND PLANT CHARACTERISTICS IN WINTER WHEAT

This research indicates that deep plonghing, plant density, soil moisture, irrigation, nutrition at different stages have different effects on secondary root number, root dry weight, root distribution, root vi gor, absorption ability of root system and plant characteristics in winter wbeat.The root system has adaption ability and automatic regulation ability to circumstance conditions or cultivation methnds. Nutrition and irrigation have a recent effect.There's close relation between root vigor(TIC reducing capacity) at late period and leaf senescence index, and yield.
