根系在植物生活中起着非常重要的作用。根系固着于土中吸收水分和矿质(包括氮素),并能合成多种有机物,保证整个植株正常代谢的进行。对农作物来说,高产优质与根系的生命活动密切有关。因而,二十多年来对作物根系生理的研究,引起了极大的重视。在甘蔗方面,国内外也做了许多工作,过去着重于环境因素对蔗根的影响。近几年来,我们对蔗根活动的若干基本规律作了研究,现在把所获资料,联系国外的一些报道综述如下。
Roots play a very important role in plant life. Roots fixed in the soil to absorb water and minerals (including nitrogen), and can synthesize a variety of organic compounds, to ensure the normal metabolism of the entire plant. For crops, high yield and quality are closely related to the life activities of the root system. Therefore, more than two decades of crop root physiology has drawn great attention. In terms of sugarcane, much work has also been done both at home and abroad, focusing in the past on the impact of environmental factors on the cane. In recent years, we have studied some basic rules of sugarcane root activity. Now we summarize some of the information we have received and the reports abroad.
