我国南方酸性土壤资源丰富,花生是该区域主要的经济与油料作物。本文利用在酸性土壤开展的国家长江流域片长沙点12年（2005-2016）品种区域试验,对来自全国82个品种的植株性状、农艺性状、产量指标等数据进行相关统计和分析,以筛选出耐酸性土壤的丰产花生品种,并明确其基本特征。结果表明:（1）酸性红壤上所有品种的平均荚果产量接近3750kg/hm2,其植株偏高而分枝数偏少,单株结果数、果仁大小及出仁率均为中等。（2）筛选出荚果产量比耐酸性土壤对照品种中花4号、中花15号（长江流域主栽品种）极显著增产,且平均产量在3000kg/hm2以上的高产品种17个,约占参试品种的1/5,主要来自偏酸性土壤的育种单...

There are abundant acid soil resources in southern China, and peanut is one of the main economic and oil crops in this region. In order to screen acid-tolerant and high yield peanut varieties and define their basic characteristics, the data of the plant characters, agronomic characters and yield indices of 82 peanut varieties from all over the country through 12 years (2005-2016) of the Yangtze River Basin regional trial in acid soil at Changsha experimental site were summarized by means of correlation analysis and other mathematical statistics. The results showed as: 1) The average yield of a...
