摘要
四川凉山州种植金太阳、凯特两个鲜食杏品种由于授粉树配置不合理和花期气候条件的影响,存在"花而不实",产量低的问题,必须进行人工辅助授粉。2010年春在凉山州西昌进行了金太阳、凯特两个品种的人工辅助授粉试验,结果:大幅度提高了座果率,达93.0%以上,比自然座果率提高50.0%以上;产量提高2倍。人工辅助授粉是凉山州杏树栽培提高座果率和产量的重要措施。
The two fresh apricots, Golden sun and Katy, must be pollinated by men as a result of the phenomenon of ＂Flowers rather than real＂ and the instable production when grown in Liangshan. During the spring of 2010, we conducted the experiment of artificial supplementary pollination. The results showed that the rate of setting fruit would increase by 50.0% or more in this way, reaching to 93.0%, and the yield was double compared with natural setting fruit. Therefore, hand-pollinate is the optimum for apricot cultivation under poor natural pollination condition.
