加利福尼亚洲位于美国的西海岸,面积为402000平方公里,人口2200万。全州共有果树145万株,1980年苹果产量为229600吨。州内东部和西部各有南北走向的山脉,阻止了太平洋的湿气东进。致使该州生长季节干旱无雨,日照充足,昼夜温差较大。我实习所在的沃森维尔地区,海拔48.8米,一月份平均气温1.1℃,七月份平均气温33.9℃,无霜期180天
California is located on the west coast of the United States, covering an area of 402,000 square kilometers and a population of 22 million. The state has a total of 1.45 million fruit trees, and the 1980 apple production was 229,600 tons. Eastern and western states have their own north-south mountain ranges that prevent the moisture in the Pacific from going eastward. As a result, the state experienced aridity during the growing season with abundant sunshine and a large temperature difference between day and night. The area of Watsonville, where I practiced, is 48.8 meters above sea level with an average temperature of 1.1 ° C in January, an average temperature of 33.9 ° C in July and a frost-free period of 180 days
