4种硼肥对甜樱桃花粉萌发及坐果的影响

摘要

[目的]研究4种硼肥对甜樱桃花粉萌发和坐果的影响.[方法]以红灯、关早和兰伯特3个甜樱桃品种为材料,研究了硼砂、硼酸、速乐硼、金钾硼4种硼剂及其不同浓度对花粉萌发和坐果的影响.[结果]4种硼剂在适宜浓度下对花粉萌发有显著促进作用,花粉萌发率较对照提高了27.93%～106.16%,其中以硼砂对花粉萌发的促进作用最强,其次是金钾硼;田间提高坐果率的效果以金钾硼最好,其次是硼砂.[结论]可通过喷施稀释1 000倍的金钾硼或稀释7 500倍的硼砂来促进甜樱桃花粉萌发和坐果.%[Objective] The aim was to study effects of four kinds of boron agent on the pollen germination and fruit setting of sweet cherry.[Method] Effects of different boron agent which were Borax,Boacic acid,Sule Boron and Jinjia Boron,and concentrations on pollen germination and fruit setting rate of Hongdeng,Meizao and Lanete of thee cheery species wee studied. [ Result]The results showed that four kinds of boron agent with proper concentration were significantly improved the pollen germination, the pollen germination rate increased 27.93％ - 106.16％ comparing with control. Among them,the most effective one for pollen germination was Borax,followed by Jinjia Boron. For Fruit Setting rate,Jinjia Boron was the most effective one,followed by Borax. [ Conclusion] Pollen germination and Fruit Setting of Sweet Cherry were improved by spraying 1 000 Jinjia Boron and 7500 Borax.
