根系不仅是水稻吸水吸肥和支持地上部的重要器官 ,同时也是许多重要生理活性物质的合成器官 ,发达的根系是水稻生长发育和产量形成的基础〔1,2〕。在我国水稻生产中具有重要地位的杂交水稻之所以高产稳产 ,其生理基础之一就是其根系发达 ,吸肥吸水能力强 ,生理代谢旺盛 〔3,4〕
The root system is not only an important organ for absorbing water and supporting the shoots of rice, but also a synthesis organ for many important physiologically active substances. Developed roots are the basis for the growth and yield formation of rice [1,2]. The reason why hybrid rice, which has an important position in rice production in our country, is high-yield and stable. One of its physiological basis is its developed root system, strong absorption of water and strong physiological and physiological metabolism [3,4]
