‘澳洲青苹’在宁夏的生态适应性分析

为提高宁夏高酸苹果生产基地规划的科学性,分析‘澳洲青苹’在各地区的生态适应性。在调查国内‘澳洲青苹’种植区生态气候条件的基础上,根据其生长发育特性,利用宁夏各地的气温、降水、日照时数、无霜期、活动积温和土壤类型等资料,分析‘澳洲青苹’对宁夏气候、土壤条件的适宜性。研究结果表明,宁夏引黄灌区由于日照充足、热量资源适合,加之土壤肥沃,灌溉便利,生态条件适宜栽植‘澳洲青苹’;中部干旱带的北部地区热量资源略显不足,加之土壤相对贫瘠,较适宜栽植‘澳洲青苹’;而中部干旱带南部和南部山区由于无霜期短、活动积温显著不足等条件限制,不适合种植‘澳洲青苹’。研究结果可以为‘澳洲青苹’生产基地的合理规划提供参考。

Ecological suitability analysis of Granny Smith in NingXia

In order to reasonable planning and construction of high acid apple production base, ecological adaptability of Granny Smith in various regions in NingXia was studied. According to the characteristics of growth and development, using air temperature, precipitation, sunshine hours, frost free period, accumulated temperature and soil type information in Ningxia, author analysis the suitability of Granny Smith on climate, soil conditions. The results showed that the ecological conditions of Yellow river irrigation area is suitable for planting Granny Smith due to the abundant sunshine, suitable heat resources, and fertile soil, irrigation facilities. North of the middle dry area is the low suitable area of Granny Smith. South of the middle dry area and South mountain area is the unsuitable area due to the short frost free period, active accumulated temperature obviously insufficient. his study can provide reference for the rational planning of Granny Smith production base.
