在辽宁鞍山南果梨栽培区以不修剪为对照,探讨重剪和轻剪对南果梨树体生长、营养和果实品质方面的影响。结果表明:重剪降低了树体干径、树高、冠径、长枝、中枝、短枝和花芽数量,但促进了延长枝的发育,增加了枝条、叶片、果实中的氮、钾、钙含量和枝条、叶片中的磷含量;重剪提高了单果质量、果实横径、Vc和总酸含量。 In the cultivation area of ​​Nanguo Pear, Anshan, Liaoning Province, non-pruning was used as a control to investigate the effects of grafting and light-cutting on the growth, nutrition and fruit quality of Nanguo pear. The results showed that: heavy cutting reduced trunk diameter, tree height, crown diameter, long branches, middle branches, short branches and flower buds, but promoted the development of branches and increased nitrogen and potassium in shoots, leaves and fruits , Calcium content, phosphorus content in shoots and leaves, and weight, fruit diameter, Vc and total acid content were increased by shearing.
