1低产茶园的形成原因茶园低产的原因有:因品种劣、树龄老、树势衰弱、稀植、缺株多、园地条件差(如陡坡无梯层、水土流失大、土层薄、肥力差),管理水平低(如少耕、不施肥、不修剪、不防治病虫草害等)或采留不当等等。较低产的旧茶园普遍情况是“稀、老、衰”。因此,我们以改土治水为中心的改园、改土、改树与补密换种
The reasons for the low-yielding tea plantation The reasons for low-yielding tea plantation are: poor variety, old age, frail weakness, sparse planting, lack of plants and more garden conditions (such as steep slopes without ladder, soil erosion, soil thin, poor fertility ), Low management (such as less tillage, no fertilization, no pruning, no pest control, etc.) or improper collection and so on. The lower yield of the old tea plant is generally “thin, old, bad ”. Therefore, we have to change the soil with water for soil improvement and water conservation, and change trees and diversification
