摘要
以‘红颜’草莓品种为试验材料,在上海冬季草莓大棚种植期间,通过4种不同补光方式处理,探讨其对设施草莓果实性状的影响。结果表明:补光方式的不同可显著影响果实大小、第二批果单株果量、单果重、可滴定酸、单株商品产量和单株总产量,对果形指数、第一批果单株果量、可溶性固形物、固酸比等性状没有显著影响;不同补光方式下的产量、产值的增量比差异显著,主要受光源数量影响,光源数量主要由行数和灯距两个因素组成,其中灯距的选择更重要。
The vinyl house culture of strawberry cultivar' Hongyan' was carried out by 4 ways of supplementary light in winter of Shanghai so as to study the fruit character as influenced by different ways of supplementary light. The results showed that ways of supplementary light could significantly influence the fruit size,fruit number per plant at the 2 nd harvest stage, average fruit weight, titratable acid, commercial yield per plant and gross yield per plant,whereas they had not a significant effect on the fruit shape index,fruit number per plant at the 1 st harvest stage,soluble solids content and ratio of soluble solids content to titratable acid; Under different ways of supplementary light there were significant differences in incremental ratios of commercial yield and output value which were influenced mainly by the number of light sources decided by both number of rows and lamp interval,and the lamp interval played a more important role.
