摘要： 采用单因素重复试验，探讨不同控水灌溉方式对水稻根系生长的影响。研究结果表明，不同灌溉方式对水稻根系影响不同，适当的控水灌溉可以增加水稻根系长度、数量、根体积及干物质的重量，同时能够增强水稻根系活力；控水灌溉能够节约用水2625m3/hm2，提高水稻产量580.35kg/hm2。

Abstract: This test uses a single-factor repeat tests, explore the effect of different ways of controlling water irrigation on root growth of rice. The results show that different irrigation ways has different impact on rice roots, the appropriate control of irrigation water can increase the length of rice root, number, root volume and the weight of dry matter, and can enhance rice root activity; controlling water irrigation to save water 2625 m3/hm2, raise Rice Yield 580.35 kg/hm2.
