密闭荔枝园的重回缩改造技术

Technology of Retraction and Reconstruction in Closed Litchi Orchard

泸州地区为我国荔枝规模化栽培的最北缘地区,是我国荔枝最晚熟产区,也是我国最早栽培荔枝的区域之一。近年来,荔枝种植面积直线上升。但在生产上存在着产量不稳定、年际波动显著、品种结构不合理、产期过度集中、老果园管理难度大等问题,因此,本文针对泸州地区密闭荔枝园树体高大、果园密闭、立地环境差,农事管理不方便等问题,总结出通过重回缩修剪改造密闭果园和冠层的一套技术措施。

Luzhou area is the most northernmost region of Litchi in China, and it is the most mature area of Litchi in China. It is also one of the earliest litchi planting areas in China. Its planting area is rising linearly. However, there are many problems in production, such as unstable output, significant interannual fluctuations, unreasonable species structure, excessive production period, and difficult management of old orchard. Therefore, in view of the Luzhou area closed litchi orchard trees, orchard closed, poor environment, spraying, harvesting management is not convenient, and difficult to prevent metallurgical problems, this paper summed up a set of technical measures through heavy retractive pruning and canopy closed orchard transformation.
