摘要
该研究利用深液流技术,以生菜、油麦菜、苦苣、茼蒿为试材,对比不同营养液配方对4种菊科叶菜生长及品质的影响,以期筛选出适于工厂化生产的营养液配方。结果表明:在同一管理模式下,不同营养液配方对叶菜的影响不同,其中配方A(N∶P∶K=15.6∶1∶10)培育的叶菜长势弱,叶色浅,商品性较差;配方B(N∶P∶K=13.6∶1.3∶8)培育的叶菜株型健壮且维生素C含量高,但叶片硝酸盐的积累量较大;配方C营养液培育的叶菜株高、根长、SPAD、单株产量等指标均高于其他处理。结合各品种的综合指标得出:配方C(N∶P∶K=12.6∶1.3∶8)在叶菜生长及品质指标测定结果中表现优异,可作为大多数叶菜生长的最佳配方,为今后水培叶菜的优质高产栽培提供理论依据。
In this study,Romaine Lettuce,Lactuca sativa L,Cichorium engivia L.and Chrysanthemum coronarium were used as test materials,the effects of different nutrient solution formulas on the growth and quality of 4 Asteraceae leafy vegetables were compared by using deep liquid flow technology,in order to screen out the nutrient solution formulas suitable for industrial production.The results showed that under the same management mode,different nutrient solution formulas had different effects on leafy vegetables.Among them,the leafy vegetables cultivated by formula A(N∶P∶K=15.6∶1∶10)had weak growth,light leaf color and poor commercial character.The leafy vegetables cultivated by formula B(N∶P∶K=13.6∶1.3∶8)had robust plant type and high vitamin C content,but the accumulation of nitrate in the leaves was large.The plant height,root length,SPAD,yield per plant of leaf vegetables cultured with formula C nutrient solution were higher than other treatments.Combined with the comprehensive indexes of various variety,it was concluded that formula C(N∶P∶K=12.6∶1.3∶8)had excellent performance in the growth and quality indexes of leaf vegetables,could be used as the best formula for the growth of most leafy vegetables,providing a theoretical basis for the high-quality and high-yield cultivation of hydroponic leaf vegetables in the future.
