以“黄金”梨为供试树种,采用纺锤形试验树形,以疏散分层形为对照,在黄棕壤上采取3种株行距(2.0m×3.0m、2.5m×4.0m、3.0m×4.0m)和对照(4.0m×5.0m),对比了不同栽植密度对“黄金”梨栽培性状、丰产优质性能和等级评价的影响,以期找到“黄金”梨适宜的栽培密度,为实现其优质丰产提供参考依据。结果表明:株行距2.5m×4.0m和3.0m×4.0m是“黄金”梨生产适宜推广的栽培密度,管理技术相对简单易行、省工省力,具有较高的栽培推广价值。
Taking “Golden pear” as tested tree species, spindle shape test tree was used to compare with evacuation stratification shape. Three rows spacing (2.0m × 3.0m, 2.5m × 4.0m, 3.0m × 4.0m) and the control (4.0m × 5.0m). The effects of different planting densities on cultivated traits, high yield and high grade performance of “Golden” pear were compared in order to find suitable “Golden” pear Cultivation density, in order to achieve its high yield and provide a reference. The results showed that the line spacing of 2.5m × 4.0m and 3.0m × 4.0m was suitable for popularizing the pear production of “Gold”. The management technique was relatively simple, easy and labor-saving, and had a high value of cultivation and popularization.
