非充分灌溉条件下水稻根系生长发育特征研究

Study on Growing Features of Rice Roots under Water Deficit Irrigation Conditions

以广西桂林站水稻非充分灌溉试验的实测资料为基础，分析比较了不同稻田水分条件下水稻根系的形态、类型、根系数量及分布特点，同时，对非充分灌溉条件下水稻根系的生长发育特征及其对产量影响的机理进行了初步研究。其结果对指导有效、省水的稻田灌溉具有重要意义。

Based on the experimental data of water deficit irrigation of rice at Guilin station of Guangxi Zhuang Autonomous Region,this paper compares the type,number and distribution pattern of rice roots with different water supply in paddy field and analyses preliminarily the growing features of rice roots and the effect mechanism of roots on rice yield under the water deficit irrigation conditions.
