作者运用~(32)P 示踪并结合 N、P 的分析,揭示了年周期中不同时期果树的生长中心转移与养分分配规律。经多年来在生产上的反复实践证明,正确地掌握不同时期的生长中心转移与养分分配规律,有利于认识不同时期果树各器官之间的相互关系,有利于认识落花落果和大小年结果等果树上许多复杂生命现象,有利于给果树进行合理施肥,为制定果树生长发育的技术措施提供理论依据。
The authors used ~ (32) P tracing combined with N, P analysis to reveal the rules for the growth center and nutrient allocation of fruit trees at different stages of the annual cycle. After years of repeated practice in production, it has been proved that correctly grasping the rules of the transfer of growth centers and distribution of nutrients in different periods is good for understanding the relationships among various organs of fruit trees in different periods, and for understanding fruit trees such as falling and falling fruit and size year results The phenomenon of many complex life is conducive to fruit trees for reasonable fertilization, to provide a theoretical basis for the development of fruit tree growth and development of technical measures.
