(一)基本情况我所金桔试验基点设在阳朔县白沙公社古板大队第三生产队。试验田计有金桔54株,占地0.9亩;株行距3.3×3.4米,亩植60株:树龄25年。植后由于栽培管理粗放及病虫危害树势衰弱,枝条枯亡、“裸枝”(即叶片脱落的枝梢)增多、产量低、落果与裂果严重,果形变小,品质降低。当地社员认为这片金桔园的植株已经衰败了。 (A) the basic situation I test the base of Kumquat is located in Yangshuo County Baisha commune stereotyped brigade third team. There are 54 kumquats in the experimental field, occupying an area of ​​0.9 mu. The row spacing of the plants is 3.3 × 3.4 m. There are 60 plants per mu: the age of 25 years. After planting, extensive cultivation and management and pest and insect pest damage caused the shrubs and branches to die. The number of “bare branches” (ie, shoots with fallen leaves) increased, the yield was low, fruit and fruit were severely damaged, and the fruit shape became smaller and the quality was reduced. Local members think this piece of kumquat plant has decayed.
