油茶是我国南方重要的木本油料树种。但目前油茶林经营技术水平普遍粗放,林相很差,产量低而不稳,一般亩产茶油五、六斤,高的也只有十来斤,与高产一百多斤的试验林比较相距甚远。油茶林低产的因素很多,常归纳为“老、杂、残、稀、荒、病、虫、劣”八个字,造成低产的原因可概括为四个:一是结果率太低;二是营养生长与生殖生长失调;三是存在大量的低产劣株;四是水肥供应不足。只有改变了上述状况,油茶丰产就有希望。现谈谈油茶经营技术“四改”建议:
Camellia is an important woody oilseed species in southern China. However, at present, the technical level of Camellia oleifera forest is generally extensive. The forest phase is rather poor with low and unstable output. Generally, there are only 5 or 6 jin of tea oil per mu, far. Camellia oleifera low yield many factors, often summarized as “old, miscellaneous, residual, dilute, shortage, disease, insects, poor” eight words, resulting in low yield can be summarized as four reasons: First, the result rate is too low; second is Nutrition growth and reproductive growth disorders; Third, there are a large number of low-yielding strains; Fourth, inadequate supply of water and fertilizer. Only changed the above conditions, there is hope for high yield of Camellia oleifera. Now talk about the business technology of Camellia “Four changes” Suggestions:
