广西苦丁茶的生产现状及无公害栽培技术探讨

广西苦丁茶生产区主要在大新县和天等县,种植面积约3 000 hm2,年产茶叶约700 t。生产过程中存在对农药和化肥的过份依赖、产品的重金属和农药超标等问题,需要通过无公害栽培来提高产品质量。该文从茶园选择、种植、土壤管理和施肥、茶树修剪和茶叶采摘、病虫害防治等方面对苦丁茶的无公害栽培技术进行了初步探讨。

Present status and non-pollution cultivation techniques of Ilex kudingcha in Guangxi

The production region of Hex kudingcha in Guangxi is located mainly in Daxin and Tiandeng County, cultivated area is about 3 000 hm2 ,annual yield of Hex kudingcha is approximately 700 t. There are several problems existing in the process of production, such as the excessive dependence on pesticides and chemical fertilizers,the exceeding of heavy metal and pesticide content limits in products, and it is necessary to apply the non-pollution cultivation in order to improve the quality of products. In this paper, proceeding from Ilex kudingcha garden's site choice, cultivation, soil management and fertilization, Ilex kudingcha tree pruning and Ilex kudingcha leaf collecting, and control of plant diseases and insect pests, we took a primary exploration on the non-pollution cultivation techniques of Hex kudingcha.
