几种叶面肥对油茶结实的影响

Effects of foliar fertilizers on fruit setting in Camellia oleifera

为给结果期油茶树科学喷施叶面肥提供参考依据,分别以盛产期油茶大树和初果期油茶树为试验材料,采用完全随机试验设计,就几种叶面肥对油茶结实的影响情况进行了喷施试验与观测分析。结果表明:就油茶大树(40年生)而言,同一品种油茶不同叶面肥处理的坐果率间存在显著性差异,不同品种油茶不同叶面肥处理的坐果率间差异仍显著;针对刚进入初果期的油茶树(4年生)而言,不同叶面肥处理的坐果率间存在显著性差异;但总体而言,与对照处理的相比,各叶面肥处理均不能显著提高油茶结果树的坐果率。

In order to provide a reference basis for scientific foliar fertilization ofCamellia oleiferatrees at fruiting period, taking trees at full fruiting period and early fruiting period as materials, effects of several kinds of foliar fertilizers onC. oleifera fruit setting were tested and analyzed, through adopting Completely randomized design. The results showed that, the fruit setting rates had signiifcant differences between the same cultivar of 40 years trees in different foliar fertilizer treatments, and those had signiifcant differences between different cultivars and different foliar fertilizer treatments. The fruit setting rates had significant differences between four years trees in different foliar fertilizer treatments. But overall, the foliar fertilizer treatments could not signiifcantly improve fruit setting rate ofC. oleifera trees compared with CK.
