摘　　要：在板栗雄花序开始出现前后，以０．２５％～１．０％的ＴＤＳ调节剂喷布处理，均能提高板栗结果率２０％以上，但以０．５％较为合适。除了喷布处理外，ＴＤＳ也适合注干和浇根处理。如在喷布时配合喷施多效唑（ＰＰ３３３）或异戊烯腺嘌呤（ＩＰＡ）５００ｍｇ／ｋｇ，表现明显的增效作用。在冬季或春季施肥也能提高ＴＤＳ的增产效果。试验结果表明，每年喷施ＴＤＳ，可年年获得增产。Fruit bearing number and seed yield of Chinese chestnut increased over 20 percent with spraying treatment of TDS plant growth regulator solution (0.25,0.5,0.75, 1.0 percent) after revealing of male inflorescence. Besides spraying treatment,TDS solution can be used to inject into trunk or pour on roots of Chinese chestnut. There are obvious effect of increasing fruit bearing number and seed yield when mixture solution (TDS and isopentenyl adenine,500 mg/kg or TDS and paclobutrazol 500 mg/kg) is used. It is conducive to TDS′s regulation to apply fertilizer in winter or in spring. The results showed that fruit bearing number and seed yield of Chinese chestnut could be raised every year,when TDS regulator was used every year.
