摘　　要：研究甜菜库源关系改变后叶面指数、地上干重、地下干重的变化,以了解甜菜不同移栽期对库源关系改变的影响,确定甜菜移栽的最佳时期。以‘KWS6167’为试材,采用同一育苗期育苗,不同时期移栽,共设4个处理——A:4月26日移栽;B:5月1日移栽;C:5月6日移栽;D:5月11日移栽。结果表明:不同处理叶面积指数不同,且同一叶面积指数不同处理持续的时间不同;地上部干物质重各处理表现不一致,A、B、C 3个处理是单峰线变化趋势,D处理是上升趋势,各处理地上干物质重和叶面积指数呈正相关关系;6月10日—8月10日,地下干物质随着叶面积指数的增加而增加,地下干物质与叶面积指数呈极显著正相关关系;8月10日—10月7日,叶面积指数逐渐减小,地下干物质则随着叶面积指数的减小而增加,地下干物质重与叶面积指数呈显著负相关关系。The authors studied changes of leaf area index（LAI）, dry mater of aerial part and dry mater ofhypogeal part, clarified impact of different transplanting periods, and determined the best transplanting date ofsugarbeet after change of the sink-source relationship. The different transplanting periods were adopted bytaking‘KWS6167＇as the test material in the same nursery of seedlings, a total of four transplanting treatmentswere set, A： April 26, B： May 1, C： May 6 and D： May 11. The results showed that： the LAI was different indifferent treatments, and the duration of identical LAI was different in different treatments; the dry matterweight of aerial part in respective treatment was inconsistent, A, B and C treatment showed a single peakchange trend, D treatment had an increase trend, there was a positive correlation between dry matter weight ofaerial and leaf area index in all treatments; with the increase of LAI, the dry matter weight of hypogeal alsoincreased so that they showed a significantly positive correlation from June 10 to August 10; with the decreaseof LAI, the dry matter weight of hypogeal increased from August 10 to October 7, the dry matter weight ofhypogeal and LAI showed a significantly negative correlation.
