随着我场新建桔园的面积逐年扩大,掌握柑桔地上部分和地下部分在本地区的生长规律,提高柑桔产前管理水平,已越来越引起栽培者的注意。柑桔的地上部分和地下部分之间是一个相辅相成的统一机体,又都各有其生理特性,从某种意义上来说,地下部分的生长状况比地上部分的生长更为重要。因此,探讨柑桔幼树根系在本地区的生长动态,为尽早形成强大的根系提供依据,是很必要的。为此,对一九八二年定植的温柑(兴津),通过单根定点观察,对根系的生长动态,进行了连续两年的观察和分析。兹
As the area of newly-built orange orchard in our farm expands year by year, it is more and more attracting the cultivators to grasp the law of growth of aboveground and underground parts of citrus in the region and improve the prenatal management of citrus. Between the aboveground and underground parts of citrus is a complementary and unified body, each with its own physiological characteristics. In a sense, the growth of underground parts is more important than the growth of aboveground parts. Therefore, it is necessary to explore the dynamic growth of citrus young root system in this area and provide the basis for forming strong root system as soon as possible. To this end, we conducted a continuous two-year observation and analysis of the growth dynamics of the root system in Wengan (Xingjin) colonized in 1982 through a single fixed-point observation.
