2、收获时分别调查各处珲花穗牛长情况、每穗果数及单株产量,并进行经济效益分析。【结果】在正常管理水平下,妃子笑荔枝花穗不经过处理和仅用多效唑处理的单穗坐果率及产量均较低;而经过短截修剪的荔枝单穗坐果率、产量及经济效益均较高。其中以多效唑处理+人工短截的产量和经济效益最高,fEl其人工支出大、工效低,仅适宜小面积应用;而采用机械短截花穗所需人T较少、效率高,适宜大面积推广应用。【结论】通过花穗修剪和多效唑处理可以调节荔枝的坐果率,只要运用得当,可以获得较高的产量和经济效益。关键词:妃子笑荔枝;花穗修剪;多效哗;产量;效益中图分类号:$667.1文献标识码:A文章编号:2095—1191(2011
