| 摘 要： | 在植物工厂LED光源环境下,以黄瓜品种中农26号为试材,研究基质不同含水量对黄瓜幼苗生长特性及需水规律的影响。结果表明:植物工厂LED光源环境下,基质含水量为85%~90%时,黄瓜幼苗的株高、茎粗、生物量、根系形态指标、壮苗指数等生长指标最优。85%~90%基质含水量处理单株幼苗总耗水量最大,达到129.72 mL,且显著提高了幼苗的水分利用效率。幼苗播种后天数与单株日耗水量的关系以线性方程最佳,表达式为y=0.355 3 x-1.887 5。综合考虑黄瓜幼苗生长和耗水特性,LED光源环境下,85%~90%基质含水量培育优质壮苗的同时能够实现水分的高效利用。

| Abstract: | Under the environment with LED light source in plant factory，taking cucumber‘ Zhongnong
No.26’ as test material, this paper studied the effects of different substrate water content on cucumber seedlinggrowth characteristics and water requirement regulation．The results showed that the plant height，stem
diameter，biomass，root system morphology index and strong seedling index, etc. of cucumber seedlings were the
best when the substrate water content was 85%-90%．The total water consumption of seedling treated with 85%-
90% substrate water content was the highest，reaching 129.72 mL；and the seedling water use efficiency was
significantly improved．The relationship between the number of days after sowing and water consumption quantity
was the best based on the linear equation．The expression was y=0.355 3 x-1.887 5．Considering comprehensively
the growth and water consumption characteristics of cucumber seedlings，under the environment with LED light
source，85%-90% substrate water content could cultivate high-quality and strong seedling while achieving high
efficient water usage． |
