摘　　要：研究了省力高效栽培模式对盛果期‘雪青’果实品质、产量和叶片光合速率的影响。结果表明:省力高效栽培模式下‘雪青’梨产量达102 546 kg/hm^2,是常规栽培模式下产量的2.13倍;果实硬度6.38 kg/cm^2,可溶性固形物含量11.9%,可滴定酸含量0.12%;与常规栽培模式相比,叶片净光合速率在果实采摘前提高30%,采果后无显著差异。省力高效栽培模式下,‘雪青’梨产量高,果实品质好,叶片光合能力强,实现梨园节本增效。The pear fruit quality and leaf photosynthetic characteristics of ‘Xueqing' pear trees at full bearing period were investigated under labor-saving and highly effective cultivation pattern. The results showed that the yield was up to 102 546 kg/hm2, which was 1.13 times compared with the traditional cultivation pattern. The fruit firmness, total soluble solid, and titratable acid content were 6.38 kg/cm2, 11.9%, 0.12%, respectively. The leaf photosynthetic rate increased 30% before fruit harvest while no significant difference was found after harvest between these two cultivation patterns. It is included that high yield, good quality of ‘Xueqing' pear fruits and high efficient leaf photosynthetic characteristics can be achieved under labor-saving and highly effective cultivation pattern.
