三、生长发育生长发育及其与环境条件的关系是果树研究中的一个基本课题,因为它是制定栽培措施的基础。二十年来,国内外从多方面进行了探索,取得了很大的成绩。对于核桃根系生长发育规律已有较深入的了解,并据此提出了许多在生产上行之有效的管理措施。在枝叶的生长、芽的休眠以及结果习性方面进行了一些研究,并对各器官的相互关系亦有所探讨。在核桃生长发育与环境条件的关系方面,不同研究者从土壤、地势、温度、水分、光照等多方面进行了研究,揭示出核桃生长发育与环境条件相互作用的一些规律。
Third, the growth and development of the relationship between growth and development and environmental conditions is a basic issue in the study of fruit trees, because it is the basis for the development of cultivation measures. In the past two decades, many achievements have been made at home and abroad through exploration. For walnut root growth and development has a more in-depth understanding, and accordingly put forward many in the production of effective management measures. Some studies have been done on the growth of branches and leaves, dormancy of buds, and the resulting habits, and the interrelationships of various organs have also been explored. In terms of the relationship between the growth and development of walnut and environmental conditions, different researchers have studied the soil, topography, temperature, moisture, light and other aspects, revealing some laws of the interaction between walnut growth and development and environmental conditions.
