摘要:

为筛选出适合冰菜苗期水培的营养液配方,采用漂浮栽培模式研究了不同营养液配方对冰菜苗期生物量和形态指标的影响。结果表明,就冰菜生物量和形态指标来看,A配方的侧枝多、叶片数多且大、冠幅大、根系长、长势最好,日本园艺通用配方和B配方次之,C配方的冰菜长势最差,不适用冰菜水培苗期生长。添加2 000 mg·L-1氯化钠的A、B配方生长的冰菜幼苗叶片和茎段上冰晶状颗粒较大。综上,配方A最适合冰菜水培幼苗生长,在该盐分浓度条件下的冰菜生长健壮、茎段和叶片上冰晶状颗粒大、商品性好。本文为冰菜水培规模化生产提供营养液配方参考。

Abstract:

In order to select suitable nutrient solution formulas for hydroponic cultivation of Mesembryanthemum crystallinum L. seedlings, a floating cultivation model was used to study the effects of different nutrient solution formulas on biomass and morphological indicators of Mesembryanthemum crystallinum seedlings. The results showed that in terms of biomass and morphological indicators of Mesembryanthemum crystallinum, formula A had the most lateral branches, large and numerous leaves, large crown width, long root system, and growth, followed by Japanese horticultural universal formula and formula B. Formula C had the worst growth of Mesembryanthemum crystallinum and was not suitable for hydroponic seedling growth. The ice crystal grains on the leaves and stem segments of Mesembryanthemum crystallinum seedlings grown with formulas A and B containing 2 000 mg·L-1 NaCl were larger. In conclusion, formula A is most suitable for the growth of Mesembryanthemum crystallinum seedlings in hydroponics. Under this salt concentration, Mesembryanthemum crystallinum grows well, the ice crystal grains on the stem and leaves are large, and the marketability is good. This article provides a reference for nutrient solution formulation for the large-scale hydroponics production of Mesembryanthemum crystallinum.
