| 摘 要： | 运用双因素随机区组设计方案 ,研究了稀土、赤霉素 (GA3)和吲哚丁酸 (IBA)三种植物生长调节剂对三个锥栗品种无性系产量增加的影响。结果表明 :稀土微肥不同浓度喷施对产量有显著的影响 ,以 40 0 ppm (A1 )为最佳 ;两种生长调节剂中 ,则以 GA3的效果更好 (B1 ) ;AB因素两种组合的混合喷施对产量的促进有交互作用 ,各种组合中以A1 B1 ,即稀土浓度为 40 0 ppm ,GA3浓度为 5 0 ppm的交互效应对产量的提高最显著。

| Abstract: | The effect of GA 3, IBA and rare earth elements on yield increase in 3 clones of Castanea henryi was studied, using double factor randomized block design. Results indicate that the spray of rare earth fertilizer is strongly productive with 400 ppm (A 1) being the best concentration. GA 3 with a concentration of 50 ppm (B 1) is better than IBA of the same concentration in yield promotion, and the combined A and B has shown an interacting effect in yield promotion. Of all the combinations A 1B 1 (i.e. 400 ppm rare earth combined with 50 ppm GA 3) has generated the best effect in yield increase. |
