根系的研究方法很多,根据不同的作物、不同的研究目的和要求,可以采取不同的方法。例如研究靜态根系的形态、分布深度和广度等的靜态研究法;研究动态根系的定位定点观察法;研究生理活性吸附表面、伤流法等。作者通过实际工作,初步体会:就綠肥根系研究来說,在諸多方法中,采用壕沟法与分层测重法相結合的方法,可以了解根系活动的基本情况,对探討綠肥高低产的原因有一定帮助,适合一般試驗需要。当然对进一步掌握根系动态生育規律和生理活动,仅靠这些方法是不解决間題的。尽管如此,从粗浅地研究根系要求出发,这一方法还是可以采用的。壕沟法是唯一能够掌握整个根系外貌特征的好方法,它可以使人了解根系入土最大
There are many methods of root research, and different methods can be adopted according to different crops, different research purposes and requirements. For example, the study of static root morphology, distribution depth and breadth of the static method; study the dynamic root fixed point observation; study of physiologically active surface adsorption, injury flow method. Through practical work, the author has initially realized that in the research of root system of green manure, in many methods, the method of combining trenching method and stratified weight method can understand the basic situation of root activity and have certain reasons for exploring the high and low yield of green manure Help, suitable for general test needs. Of course, to further grasp the dynamic root system of reproductive laws and physiological activities, these methods alone do not solve the problem. However, this method can still be used to study the root requirements superficially. The moat method is the only way to grasp the overall appearance of the root system. It can make you understand that the root system is the largest
