水肥草调控对玉露香梨果实产量和品质的影响
Effect of Water and Fertilizer Regulation on Fruit Yield and Quality of Yuluxiangli with Grass Between Rows
摘要
Abstract
This study used 4-year-old Yuluxiangli pears as test material to investigate the effects of substituting organic fertilizer for nitrogen fertilizer,irrigation volume,inter-row grass,and zinc fertilizer on the yield and quality of Yuluxiangli pears.The results indicated that the optimal combination for yield and number of fruits per tree was fertilizer Baimaigen plus irrigation volume of 180 m³ plus 10％nitrogen substitution with organic fertilizer plus Zn 900 g·667-1m-2.Principal component analysis(PCA)of the fruit quality indicators showed that soluble solids,titratable acid,and fruit hardness contributed the most to the variance in fruit quality,with contribution rates of 36.05％,19.53％,and 17.35％,respectively,resulting in a cumulative contribution rate of 72.93％.Under different conditions of irrigation volume,organic fertilizer substitution for nitrogen,inter-row grass species,and zinc application,the comprehensive quality score of Yuluxiangli fruit was highest for treatment T10,which is fertilizer Baimaigen plus irrigation volume of 180 m³ plus 15％nitrogen substitution with organic fertilizer plus Zn 900 g·667-1m-2,and is recommended for vigorous promotion in orchards in the suburbs of Yinchuan.关键词
