3种适用于丘陵山地梯台梨园棚架栽培架型的制作与架设方法

Three Trellis Type Manufacture and Construction Methods for Trellis Cultivation of Pear Slope Orchard in Hilly and Mountainous Regions

为加快棚架栽培技术在丘陵山地梨园的推广,经多年探讨筛选出独栋小平面棚架、独栋Y字形棚架及独栋单斜面棚架3种适宜丘陵山地梯台梨园推广的架型。3种架型主要由立柱架、立柱锚、拉锚、固枝线(其中独栋小平面棚架另含1根主枝延长枝抬高线)构成,其中独栋小平面棚架适宜于宽3 m及以上台面丘陵山地梯台梨园"双臂顺行式"等树形整形修剪方法选用,独栋"Y"字形棚架适宜于宽3 m及以上台面丘陵山地梯台梨园"Y’字形树形整形修剪方法选用,独栋单斜面棚架适用台面宽3 m以下丘陵山地梯台梨园单臂式树形整形修剪方法选用。

In order to speed up popularization of pear trellis cultivation in hilly and mountainous regions, three trellis type manufacture and construction methods were screened based on production for years： single flat trellis, single Y-shape trellis and single one-slope trellis. These three trellis types were consisted of pillar support, pillar anchor, tension anchor and fixed branch line. Single flat trellis had a special elevated line for elongated shoot of main branch. Single flat trellis was suitable to double-arm and direct-row tree shape at over 3 m-width flat of slope orchard. Single Y-shape trellis was suitable to Y-shape tree shape at over 3 m-width flat of slope orchard. Single one-slope trellis was suitable to one-arm tree shape at less than 3 m-width flat of slope orchard.
