一、前言有机体的各个器官之间是相互联系,相互制约的,它们之间是一个不可分割的统一体,在统一的基础上各个器官都有其特性,它们在生态因素人为条件的综合作用下也发生着一系列的相适应的反应和变異,我们研究根系的目的也就在于确定根和地上部之间的关系,根系的生理机能,根系生长发育的规律性,与生态因子之间的关系,以及对人为栽培条件的反应及在丰产中的作用。从而掌握其规律,应用其规律,为根系生命活动创造最有利的条件以为制定农业技术措施的依据。果树植物根系的研究工作虽早在1852年鲍布林斯克就已经开始,但由于在研究方法
I. INTRODUCTION The organs of the organism are interrelated and mutually restricted. They are an indivisible unity. On the basis of unity, all the organs have their own characteristics. Under the combined effect of artificial conditions of ecological factors A series of adaptive reactions and variations also occur. The purpose of our study of the root system is to determine the relationship between root and shoot, the physiological function of the root system, the regularity of root growth and development, and the ecological factors Relations, as well as the response to artificial cultivation conditions and the role of high yield. So as to grasp its law and apply its laws to create the most favorable conditions for root life activities in order to formulate the basis for agricultural technological measures. Although the research work on the root system of fruit trees has begun as early as 1852 in Boblinsk,
