控释肥与叶面肥对盆栽草莓的影响

Effects of controlled release fertilizer and foliage fertilizer on potted strawberry

以草莓品种‘红颜'为试验材料,通过调查草莓相关指标,探究控释肥与叶面肥对草莓‘红颜'营养生长、繁殖、产量等的影响,为基质盆栽草莓提供施肥技术和方法。结果表明:①叶面肥和控释肥对草莓营养生长有促进作用,除功能叶数外,对其他性状的促进作用都是显著的;控释肥对功能叶数和株高的影响达到极显著水平。②叶面肥增强了草莓的无性繁殖力,有效分株和匍匐茎分别增加了38.64%和133.77%;控释肥增加了草莓的有效分株,而降低了草莓匍匐茎数。③控释肥和叶面肥对基质盆栽草莓结果数和产量都有显著的负面影响。

The strawberry variety Hongyan was used as a test material,and its vegetative growth,reproduction and fruit yield were investigated so as to explore controlled release fertilizer and foliage fertilizer practices of soilless potted strawberry.The results indicated that both foliage fertilizer and controlled release fertilizer had a significant accelerating effect on the vegetative growth of strawberry except the functional leaves,while controlled release fertilizer very significantly influenced the number of functional leaves and the plant height;Foliage fertilizer enhanced the asexual reproduction of strawberry,with the effective offshoots and stolons increasing by 38.64%and 133.77%respectively;Controlled release fertilizer increased the effective offshoots of strawberry but reduced the number of strawberry runners;Both foliage fertilizer and controlled release fertilizer had a significant negative effect on the fruit number and yield of soilless potted strawberry.
