不同栽植密度与整形方式对翠冠梨早产丰产性研究

Research on the Productivity and Early Ripening of Cuiguan Pear under Different Cultivated Densities and Different Pruning Means

通过连续6 a对不同栽植密度与整形方式下的翠冠梨进行调查研究,结果表明:倒"人"字篱壁形矮化密植栽培与乔化稀植栽培、纺锤形栽培相比,梨树物候期相对提前,单位面积植株新梢生长量、成枝量、叶面积系数大,单株产量高,果实品质也有较大改善,适合在梨树上推广应用。

Through six consecutive years＇ investigation and research on Cuiguan Pear which were inseminated and pruned in different ways, results showed： the phenology of Cuiguan pear under the inverted“person”shaped close planting became earlier than other cultivated densities and pruning means. The inverted“person”shaped dose planting can increase the number and growth of annual branches and the leaf area index of Cuiguan pear, improve the yield of every tree and ameliorate the fruit quality. It was suitable for application in the pear tree.
