摘要
作者在低纬度、高海拔的高原山地—川西阿坝州以及东北温带苹果主产区,西南高地,西双版纳和华南热带亚热带生态代表型区进行了广泛调主研究和综合比较。初步探讨了光、热、水、气、地形等主要生态条件对苹果生长发育、产量品质形成的生态作用和生态指标:提出了我国西南高地苹果生态适宜性的主导因素与指标是恰当的海拔高度和地貌组合;年平均气温9(8.5)—12.5℃,≥10℃年积温2500—3500℃;6—9月的月平均气温16.0—22.0℃、月均气温较差>10℃、月均相对湿度<70％,月日照时数>160(150)小时,紫外光较多。为苹果生态区划提供了依据。
This paper summarized the results of the study on the typical ecotype of ABa, The west area of Sichuan zone. These studies were carried out by the author for more than 10 years. The region of investigation iucludes between 18°30′—47°10′N and 97°45′—125°54′E, with the elevation of 3—4800 meter.The rasults which were preliminary represented the leading factors and indexes for ecological suitability of apple in southwestern highland in China are: 1. The combination of suitable latitude and geomorphic features; 2. The annual mean temperature [9(8.5-12.5℃)] and≥10℃ accumulitive temperature(2500—3500℃): 3. From June to September, the monthly mean temperature (16.0—22.0℃), temperature range(>10℃)and relative humidity(<70%), as well as solar hours [>150(160)] with more ultraviolet.
