以二水早大蒜为试材,探讨了不同的补光方法对冬季温室栽培大蒜鳞茎膨大及其品质的影响。结果表明,在连续光照达到14小时条件下大蒜鳞茎才能显著膨大,非连续光照8~14小时,即在7小时自然光照条件下,21:00~4:00打破黑暗补光1~7小时处理均能促进鳞茎膨大,并且鳞茎质量均高于14小时连续光照处理;不同打破黑暗处理之间鳞茎质量无显著差异。随着打破黑暗补光时间的延长,大蒜叶片色素含量,鳞茎中大蒜素、可溶性糖、维生素C、
The experiment was conducted to study the effect of different light compensation methods on bulb expansion and its quality in winter greenhouse. The results showed that under continuous illumination of 14 hours, garlic bulbs could be significantly expanded, discontinuous illumination 8 to 14 hours, that is, under the natural light conditions of 7 hours, break the dark light from 1 to 7 hours at 21:00 to 4:00 Bulblets can be promoted, and the quality of bulbs are higher than 14 hours of continuous light treatment; Bulb quality between different breaking dark no significant difference. With the extension of dark time to break light, garlic leaf pigment content, allicin in the bulb, soluble sugar, vitamin C,
