我县水井槽村属于低山地区,海拔500米左右,适应发展柑桔。该村七、八两个组自1970年以来先后种植柑桔3700株。多年来由于不治虫、不防病、不追肥、不整枝、不保花保果的粗放管理,部分柑桔树成了“小老树”,不开花,不结果。1984年仅收288.5公斤,株平0.65公斤。1985年虽是大年,也只收果4025公斤,株平1.1公斤。为了使现有资源尽快转化为商品。帮助农民脱贫致富,笔者于1986年冬开始,对该村低产桔园进行改造,取得了明显的效果,1986年总产达到925O公斤,比1985年增加1.3倍。1987年总产上升到27000公斤,又比1986年增加1.8倍多。8年不开花、13年不结果的树已正常开花、结果。每斤果数由过去7、8个降到5个左右。过去受介壳虫、锈壁虱、煤烟病为害造成“黑果”、“疤果”率在50%以上,现在降到5%
I County shui trough village belongs to the low mountain area, about 500 meters above sea level, to adapt to the development of citrus. The village seven or eight two groups since 1970 planted 3700 citrus. Over the years as a result of pest control, disease prevention, no dressing, not pruning, do not guarantee the extensive management of fruit and nuts, some citrus trees became a “small tree”, not flowering, no result.

In order to make the existing resources into commodities as soon as possible. Help farmers to get out of poverty, the author started in the winter of 1986, the village of low yield orange orchard transformation, and achieved remarkable results, total output reached 925O kg in 1986, an increase of 1.3 times over 1985.
