陕西不同生态区苹果品质差异及与气象因子的关系
Relationship Between Apple Quality and Meteorological Factors in Different Ecological Regions in Shaanxi
摘要
Abstract
With the purpose of improving the certification of meteorological quality for apple,this paper utilizes the survey data as well as meteorological and phenological monitoring data and analyzes the quality of the apples from 31 planting and production bases and 155 orchards in Shannxi by means of grey relational analysis and stepwise regression.The differences in the apply quality among the four ecological areas,namely Yanan area,eastern Wcibei area,western Weibci area and Guanzhong area,are also analyzed.In addition,the key phenological period and meteorological factors are studied too.It is found that the fruit shape index and titratable acid content in those ecological areas are at similar levels.There is an obvious difference in the single fruit weight,soluble solid content and fruit coloring degree.The maximum temper ature in the first fruit swelling period,the maximum temperature during the growth season and the average temperature in the young fruit period have very significant influences on apple quality.The quality of apples in Shannxi can be enhanced by higher temperature and less rain in the bloom period and young fruit period,low temperature and abundant sunshine in the first swelling period as well as the low temperature and high relative humidity in the coloring period.The quality prediction model built through the multi-var iable regression can achieve the better fitting effect and thus could be applied to the actual production.关键词
