几种化学药剂对早熟桃果实品质的影响

EFFECTS OF A FEW KINDS CHEMICALS ON THE QUANITY OF EARLYMA-TURING PEACHFRUIT

以５年生毛桃砧布目早生桃为试材，采用叶面喷施方法，研究了植物生长调节剂和营养元素对提高早熟桃果实品质的效应。结果表明，丰果素１号、甜之宝、磷酸二氢钾、比久（Ｂ９）、植物生长剂、氯化钾促进果实着色的效果明显；除了比久有降低单果重的趋势外，其余各处理都能增加单果重７％～１７％，与对照呈显著性差异；丰果素１号、增糖灵、磷酸二氢钾提高可溶性固形物（１．３％～１．５％）的效果最佳；丰果素１号、增糖灵、甜之宝、磷酸二氢钾、达苜生、２１１－３２农用稀土复合剂增糖（１．３％～１．５％）效果明显，它们（除磷酸二氢钾外）的减酸（０．１１％～０．１２％）效果也显著。尤其是丰果素１号对提高果实着色、增加单果重、提高可溶性固形物和总糖，降低果实中总酸含量均有显著作用，可在生产上应用。

In this study,five-year Amygdalus Persica Nunamewas is taken as experimen-tal material.Foliar application of plant regulator and nutrient is adopted to study their effectson promoting the quanity of early- maturing peach fruit.The results obtained show that the effects of Feng Guo Su No. 1,Tian Zhi Bao.KH2PO4,B9,plant regulator and Potassium Chlo-ride to promote peach fruit clouring are obvious. In all the treatments,only B9 reduces per fruit weight,and all the others can increase per fruit weight by 7%～17%They show signifi-cance with the contrast group and can be used in peach production.
