摘　　要：在5年生板栗园内套种百合,从距树干1 m向周围扩展,分别采用15 cm×20 cm,15 cm×30 cm,20 cm×30 cm,25 cm×30 cm,30 cm×30 cm的株行距栽植百合种球。定植后第3年,于现蕾期分别测定植株中部叶片的光合面积、比叶重、叶绿素含量,秋季采收百合鳞茎。结果表明,百合植株叶片的生理指标及单位面积鳞茎产量和大鳞茎产量比率均是:稀植>中度密植>密植。板栗林下套种百合以30 cm×30 cm密度为宜。In a 5-year-bom chestnut orchard, interplanting lily bulbs around 1 meter away from chestnut tree stem at the densities of 15 cm×20 cm, 15 cm× 30 cm, 20cm× 30cm, 25 cm×30cm, 30 cm× 30 cm, respectively. In the third year after field planting, test photosynthesis area,chloro phyll and specific leaf weight of the middle leaves at bud appearing stage. The results showed that all the tested physiological index,unit area output and big bulb percentage at the density of 30cm × 30 cm were the best.
