一、合理间伐,优化果园群体结构间伐是郁闭园改造最简便易行的技术措施,也是打开果园光路和作业通道、提高生产效率最有效的途径。根据树龄、栽植密度和果园郁闭程度,可以采取“一次性间伐”和“计划性间伐”两种模式。1.一次性间伐。对树龄15年生以上的盛果期果园或高密度(如株行距2m×3m、1.5m×4m、2m×4m、3m×3m、2.5m×4m、2m×5m等)果园,可采取一
I. Reasonable Thinning and Optimizing Inter-Orchard Structure Thinning is the most simple and easy technical measure for the transformation of the park. It is also the most effective way to open the orchard’s light path and work channel and improve the production efficiency. According to the age of trees, planting density and orchard canopy density, can take “one time thinning” and “planned thinning” two modes. One-time thinning. Fruit orchards at high fructification age of 15 years or above or high density (such as 2m × 3m, 1.5m × 4m, 2m × 4m, 3m × 3m, 2.5m × 4m, 2m × 5m etc.)
