青海地方特色果品软儿梨矮化密植树形的筛选

Selection of Dwarfing and Densely planted Tree Form of Soft Pear,a Local Characteristic Fruit in Qinghai

矮化密植是现代果树栽培的主要方向。但我省特色果品—软儿梨树的栽培仍沿用较为原始的乔化栽培模式,其高大的树体,使得修剪、喷施叶面肥等农艺措施无法开展,致使软儿梨树树形杂乱,果实产量和品质逐年退化,从而严重制约了我省地方特色果品的经济发展。针对以上现状,我单位开展软儿梨树矮化树形的筛选研究,通过综合评比,确定适宜软儿梨矮化密植的矮化树形为主干形,该树形具有建造快,修剪量小、成本低等优点,为我省软儿梨树矮化密植栽培提供最佳树形。

Dwarfing and dense planting is the main direction of modern fruit tree cultivation.However,the cultivation of soft pear,the characteristic fruit of our province,still follows the relatively primitive cultivation mode,Its tall tree body makes pruning,spraying foliar fertilizer and other agronomic measures impossible,and cause the tree shape of soft pear to be disorderly,the fruit yield and quality to be degraded year by year,which seriously restricted the economic development of local characteristic fruit in our province.In view of the above situation,our unit carried out selection research on the dwarfing tree shape of soft pear.Through comprehensive evaluation,the dwarfing tree shape suitable for the dwarfing and dense planting of soft pear was determined as the main tree shape,and the tree shape has the advantages of fast construction,pruning a little and low cost,which provides the best tree shape for dwarfing and dense planted of soft pear in our province.
