“黄金”梨不同栽培密度对比试验

Contrast Test of Different Cropping Density to‘Huangjin'Pyrus L.

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。

‘Huangjin＇Pyrus L.was used as test tree,spindle shape as the test tree shape,evacuation layered form as the control,in the yellow brown soil,three spacing in the rows and between rows were conducted（2.0m×3.0m,2.5m×4.0m,3.0m×4.0m）and with control（4.0m×5.0m）,the‘Huangjin＇Pyrus L.cultivation characters and yield quality performance and evaluation of the situation were compared,to find‘Huangjin＇Pyrus L.suitable planting density,to realize the high quality and high yield.The results showed that the line spacing of 2.5m×4.0mand 3.0m×4.0m were‘Huangjin＇Pyrus L.production suitable planting density for promotion,management technology was relatively simple,labor-saving,with higher value of promotion and cultivation.
