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 effects of labor-saving and high-efficiency cultivation modes on fruit quality, yield and leaf photosynthetic rate of ’Qingqing’ were studied. The results showed that the yield of ’Qingqing’pear reached 102 546 kg / hm ~ 2, which was 2.13 times higher than that of conventional cultivation mode under the labor saving and high efficiency cultivation mode. The fruit hardness was 6.38 kg / cm ~ 2, the soluble solid content was 11.9% The acid content was 0.12%. Compared with the conventional cultivation pattern, the net photosynthetic rate of leaves increased 30% before the fruit picking, and there was no significant difference after picking fruit. Labor-saving and efficient cultivation mode, ’snow green’ pear high yield, good fruit quality, leaf photosynthetic ability, to achieve efficiency syrup Liyuan Festival.
