摘要
选择NAA、乙烯利为疏花疏果药剂,对成花量大、坐果率高、宿果时间长的红珠宝海棠进行了化学疏除试验。结果表明,乙烯利与NAA复配疏除花果效果较好,其中550 mg/L乙烯利+350 mg/L NAA效果最好,每花序坐果0.433 3个,疏果率达91.390 7%,能满足生产需要。
NAA and ethrel were selected as thinning agents of blossom and fruit,and chemical thinning experiments were carried out on Malus sp.′Jewelcole′with large amount of flowers,high fruit setting percentage and long fruit setting time.The results showed that the combination solution of ethrel and NAA had better effect on thinning of blossom and fruit,among which,550 mg/L ethrel+350 mg/L NAA had the best effect,with 0.4333 fruits per inflorescence and 91.3907%fruit thinning percentage,which could meet the production needs.
