摘要
在锥栗结果母枝抽生花序前 ,用TDS生长调节剂 (质量浓度分别为 3、5、7g·L- 1)对锥栗树冠进行喷布处理 ,能明显提高坐果率。如在雄花序出现的初期再以同样的浓度喷布 1次 ,增产效果则更好 ,以抽生花序前和雄花出现的初期 2次连续喷布 5g·L- 1的TDS溶液增产效果最佳 ,其坐果率和单株产量分别比对照 (喷清水 )增加 5 7.3%和 2 2 .2 %。
Fruit bearing number of chinquapin ( Castanea henryi ) would be increased obviously with the treatment of spraying TDS growth regulator so1ution (3,5,7 g·L -1 ) before revea1ing of male inflorescence.Results of increasing fruit bearing number and seed yield with the treatment of spraying the same concentration TDS growth regulator solution one more time early before revealing of male inflorescence is better than that with the treatment of spraying TDS growth regulator only before revealing of male inflorescence.The best results increasing yield would be obtained with the treatment of spraying 5 g·L -1 TDS growth regulator solution before and early before revealing of male inflorescence.Fruit bearing number and seed yield would be raised 57.3% and 22.2% respectively.
