摘要
本文利用元帅系苹果定位试验的品质测定资料,分析研究了苹果品质(含糖量、含酸量、硬度等)与海拔高度及其垂直气候层带的关系,认为我国渭北黄土高原海拔1000—1500m 范围的半湿润、半干旱地区,是全国苹果品质最佳的优质气候区。这一层带的气候-土壤生态条件,适宜于发展优质苹果生产和建立商品生产基地。
In this paper, Authors apply measured data of Marshal Line apple's quality to research correlation about apple's qualities (such as sugar content, sour content, hardness etc.) with climatic belt in different altitude. The results inditated that 1.0-1.5km above sea level in the North of Weihe River among hte Loess Plateau is optimum climatic region of high quality apples in our country. The climate and soil ecotype in this belt are adaptation to develop production o'f high quality apples and should be built a base of economical production.
