研究了土壤浸施多效唑和叶面喷施矮壮素及二甲胺基琥珀酸对芒果产量和果实品质的影响。供试品种为“阿方索”９年生树。每株施２．５克或５克多效唑显著提高产量，但用量加大到每株１０克则降低产量。施用二甲胺基琥珀酸，浓度为每升３０００毫克的处理略为增产但降低可溶性总固形物含量。高剂量施用多效唑的处理，果实变小，对可溶性总固形物含量和糖／酸比均有不良影响，而且延缓果实成熟。对果实的其他理化性状无影响。推荐隔年施用多效唑，每株２．５克，于１１月至３月之间施用，可控制植株大小并提高幼龄结果树的产量。
The effects of soil application of paclobutrazol (PP333) and foliar application of CCC and dimethylaminosuccinic acid on mango yield and fruit quality were studied. Test varieties for the “Alfonso” 9-year-old tree. The application of 2.5 g or 5 g of paclobutrazol per plant significantly increased the yield, but increasing the amount to 10 g per plant reduced the yield. Administration of dimethylaminosuccinate at a concentration of 3000 mg per liter slightly increased yield but decreased total soluble solids content. High-dose paclobutrazol treatment, the fruit becomes smaller, the total soluble solids content and sugar / acid ratio has an adverse effect, but also delay the fruit ripening. No effect on other physical and chemical properties of the fruit. It is recommended that paclobutrazol, 2.5 grams per plant, be applied every other year for the period from November to March to control plant size and increase the yield of young results trees.
