以苹果的生草园和清耕园为研究对象,通过分析苹果果树不同树冠、不同部位果实品质与果园生草处理的相关性,及果实内部品质因素之间的相互关系,探寻用于改善果园生态环境的方法,进而达到果树优质高产的目的。结果表明:经过多年生草的果园,果树的上、中、下层的果实产量明显高于清耕园,生草园果实品质在不同冠层不同部位上的单果质量、可滴定酸、维生素C含量等方面也要优于清耕果园,果实的内在与外在品质之间以及内在品质之间均存在显著或极显著的相关性,经主成分分析处理后,2种果园果实品质的因子载荷量差异明显。
Taking apple grassland and clearing farmland as the research object, this paper studies the relationship between the fruit quality of different parts of apple tree and the grass orchard, and the relationship between the fruit internal quality factors, Ecological environment, and thus achieve the purpose of high quality and high yield of fruit trees. The results showed that after perennial grass orchards, the fruit yield of the upper, middle and lower layers of fruit trees was significantly higher than that of QingGuoYuan. The quality of fruits in different parts of the canopy garden was also different, such as the content of titratable acid and Vitamin C There were significant or extremely significant correlations between internal and external qualities of fruit and internal quality of fruit orchard. After the principal component analysis and processing, there were significant differences in the fruit weight of two orchards.
