不同抑芽剂对烤烟腋芽的控制效果研究
摘要:本试验通过除芽通、烟净、菜草通等抑芽剂与人工抹芽处理比较试验,得出以下结论:施药处理有利于中上部生长及干物质积累,提高中上部单叶重,但下部单叶重有降低趋势,其中除芽通及烟净处理下部叶提早一周成熟采收。除芽通的抑芽效果最好。在施药后20天,各施药处理的抑芽效果均在90%以上。30天后,%,%,而烟净处理的抑制效果为-%。施药处理经济性状明显优于人工处理,有着显著差异。化学成份差异较小。综合评价,以菜草通表现最优。
Abstract: This experiment through eliminates the bud to pass CHUYATONG,
YANJING,CAICAOTONG,the vegetable grass to pass and so on to damp the bud medicinal preparation and to wipe the bud parison test artificially only, draws the following conclusion: Shi Yao processes is advantageous and does the material in the upside growth to accumulate, enhances upside Shan Yezhong, but lower part Shan Yezhong has reduces the tendency, lower part passes and the smoke except the bud processes the leaf to shift to an earlier time one week mature recovery only. Eliminates the bud to pass damps the bud effect to be best. In Shi Yaohou 20 days, each Shi Yao processes damps the bud effect above 90%. 30 days later, eliminates the bud to pass damps the bud effect is %, passed pared to the vegetable grass to be higher than %, but the smoke processed only suppresses the effect for - %. Shi Yao processes the economic character to surpass the manual handling obviously, has the remarkable difference. The position difference is small. The quality synthetic evaluation, passes the performance by the vegetable grass to be most superior. key word: o Damps the bud rate to produce the quality position
