沿海风沙地种植柑桔具有速生快长,提早丰产的特点,但在较密植的条件下,又有早封行,产量快跌的现象。长乐县大鹤果林场风沙地福桔密植园(行株距3×2.5米),十年生即开始封行,由于园内荫蔽,树冠下部和内部透光不良,造成枯枝多,营养枝纤弱,着果率低,果实着色欠佳,果园管理不方便,和沙皮病、蚧类等病虫害严重以及单产提不高等密植园后期问题。为解决这些问题,我们在单产尚未大幅度下降前,进行梅花形间伐和大树移植试验,以探讨使稀疏园早期复产和移植园早期投产的有关技术问题。
The cultivation of citrus in the coastal sandy land has the characteristics of fast growing, fast growing and early yielding. However, in the more densely covered conditions, there are also the early closure and the rapid decline of output. Changle County, Dacosong Forest Farm Fukuai close orange plantation (row spacing 3 × 2.5 m), beginning ten year or so seal, due to shade within the park, the lower part of the canopy and poor light within the Department, resulting in dry branches, weak nutrition branch, Low rate of fruit, poor fruit coloring, orchard management is not convenient, and shaddie, scale and other diseases and pests serious yield and yield is not high, and other late plantation problems. In order to solve these problems, we conducted the trial of plum blossom thinning and large tree transplant to see the related technical problems of the early re-production of the sparse garden and the early commissioning of the transplant garden before the yield reduction has significantly decreased.
