砂梨和日本梨生态适应性的探讨及展望

通过对砂梨在我国的生态适应性与日本梨在日本主产区的气候条件的分析和比较，认为秦岭、淮河、长江流域及其以南的广大地区与日本国梨产区气候条件相似，都适合砂梨及日本梨的生长发育，主要差异在栽培技术水平和新技术的应用上。引进和借鉴日本梨的栽培技术和独特的栽培方式，将会提高我国广大砂梨适栽区梨树的栽培水平、果品质量及市场的占有率。

On the Ecological Adaptability of Sandy Pear Cultvars And Their Growing Perspective

Through analysis and comparison of the climatic conditions of the main sandy pear (Pyrus pyrifolia Nakai) producing are in China and Japan it is clear that the ecological conditions in the areas where the Japanese pears have been extensively grown in Japan are quite similar to the ecological conditions of the areas from the line of Qinling mountains, Huai River, and Yangtze River southward in China, where the ecological conditions are suitale to be grown the cultivars of Pyrus pyrifolia Nakai, including the Jaanese pear cultivars. The Japanese pear growers have a set of unique cultural techniques guaranteeing the high production and high quality, it is worth for us to learn to improve our cultural techniques for promoting our pear production and quality.
