摘　　要：为了摸清安徽省江淮丘陵地区水稻"颖壳不闭"土壤养分限制因子,采用土壤养分状况系统研究法,通过化学分析、吸附试验及盆栽试验,以高粱为指示作物,对安徽省江淮之间的肥东县、长丰县和颍上县水稻"颖壳不闭"土壤的养分限制因子进行系统研究。结果表明:三县土壤养分限制因子主要是肥东为Zn、N、P、K,长丰为Zn、N、K、P,颍上为N、K、P、Zn。江淮之间的水稻"颖壳不闭"的土壤缺素是几种元素综合作用的结果。In order to find the soil nutrients limiting-factors of the Rice spike develop abnormality in Jianghuai Hilly Land ,the soil nutrients limiting factors in those areas were studied with a systematic approach technique on soil nutrient status through laboratory analysis,absorption study, pot experiment and using sorghum as indicator plant in Feidong,Changfeng and Yingshang in Anhui province.The result displayed that the main soil nutrients limiting-factors of Feidong soil were Zn, N, P, K, Zn, N, K, P of Changfeng soil and N, K, P, Zn of Yingshang soil.The reason comprehensive function of the Rice spike develop abnormality in the Jianghuai Hilly Land were these nutrient elements.
