初结果的幼龄柑桔营养生长由强逐渐转弱,生殖生长由弱逐渐转强,是扩冠与结果同时并进的时期,地下水平根大量生长发育,根系迅速扩大,树冠也加速扩展,单株产量逐年上升。此时期,既要注意扩冠速度,又要防止结果过多,而导致树势早衰,形成大小年结果。初结果幼树的管理关键:确保上年的叶片在6月初以前不大量落叶,调控春梢,除夏梢,缓和梢花、梢果矛盾,使光合产物重点供应幼果,从而解决幼树座果难的问题。7月上
The initial results of young citrus nutritional growth gradually weakened from strong to weak, reproductive growth gradually weaker, is the expansion of the crown and the results of the same period, the underground horizontal root mass growth, rapid expansion of the root system, the crown also accelerated the expansion of single Plant production increased year by year. During this period, we should not only pay attention to the speed of crown expansion, but also prevent excessive results, leading to the premature decline of tree vigor and the formation of annual results of size. Early results Young tree management key: to ensure that the leaves of the previous year in early June before a large number of leaves, the regulation of spring shoots, in addition to the summer shoots, ease the shoot flowers, shoot the fruit conflicts, so that focus on supply of photosynthetic products young fruit, Fruitful problem.
