几种化学药剂对早熟筑波桃坐果及品质的影响

以４年生山桃砧筑波早熟桃为试材，采用叶面喷施方法，研究了植物生长调节剂和微量元素对早熟桃坐果以及果实品质的效应。结果表明，在所选用的三个药剂当中，从提高坐果方面看，ＢＲＳ制剂比施康露和施尔得好，全株比对照高８．０％，短果枝以及花丛枝比对照坐果高２８．６％，差异显著；从提高果实品质方面看，ＢＲＳ和施康露效果明显，施康露并能有效地增进果实着色程度和表面光洁度。

Effects of Some Chemicals on the Fruit Set and Quality of Early Maturing Zhubo Peach

Study was conducted with 4-year-old trees of Zhubo peach variety, and sprayed with 3plant growth regulators for studying the effects on fruit set and fruit quality. Results showed thatthe BRS was the best one for increasing fruit set, 8. 0% higher of per tree and increased by 28. 6%of the short fruit-bearing twigs and rosette-like twigs, while for improving fruit quality the BRSand Shikanglu were likely better; the latter was good for increasing the fruit color and finish.
