针叶樱桃性喜光热，怕低温冷害，果实中维生素C(以下简称“VC”)含量很高(相当于普通樱桃的190倍)；果实娇嫩，紫外线越强，VC含量越高，采摘后VC流失很快。巴西彼得罗利纳是世界少有的针叶樱桃产区。当地经济落后。针叶樱桃主要用于手工制作果汁、果酱。中国曾尝试引种该地的针叶樱桃，未获成功。2008年，中国Y企业在该地建立保健品生产基地，提取针叶樱桃中的VC生产保健品。
(1)分析彼得罗利纳有利于针叶樱桃生长的光照条件。
(2)分析中国Y企业在彼得罗利纳建设保健品生产基地的原因。
(3)说明该保健品生产基地的建设对彼得罗利纳针叶樱桃产业的有利影响。
正确答案及解析
正确答案
解析
(1)彼得罗利纳位于低纬高原，太阳高度较大，太阳辐射强；降水少，晴天多，日照时间长，因此光照丰富，紫外线强。
(2)原因：彼得罗利纳针叶樱桃产量多，富含VC，营养价值高；果实采摘后VC流失很快，需要靠近樱桃产区尽快进行加工；保健品体积小、重量轻，便于运输；当地经济落后，劳动力和土地价格低；政策支持。
(3)有利影响：延长了产业链，增加了产品的附加值，促进产业升级；使针叶樱桃市场需求增加，种植面积扩大。
