我国早熟梨品种区划研究

分析了我国梨的生产现状,阐述了目前我国主要栽培的优良早熟梨品种。并从生态学、气候学、品种生物学和市场需求的角度阐述了早熟梨品种区划的原则和依据,据此把我国早熟梨区划为华南早熟梨栽培区,云贵高原早熟梨栽培区,四川盆地及江淮平原早熟梨栽培区,黄河故道优质早熟梨栽培区,豫、晋、陕3省交界早熟梨栽培区和环渤海早熟梨栽培区。

A Study on the Regionization of Early-maturing Pear in China

This paper analyzed the present situation of pear production,defined the content of early-maturing pear variety and introduced the main high quality early-maturing pear cultivars in China.It also expounded the principle and evidence of the early-maturing cultivar regionization based on the bionomics,climatology,cultivar-biology and the market.Hereby it was divided: South China early-maturing cultured region,Yun-Gui tableland cultured region,Sichuan basin and Jiang-Huai plain cultured region,the old valley of Yellow river cultured region,the boundary of Yu, Jin and Shan cultured region and the surrounded-Bohai gulf cultured region.It provides the theory basis for the development of Chinese early-maturing pear in the future.
