摘要:为优化新型潮汐式无土栽培设施的叶菜营养液配方,本实验在山崎叶菜营养液配方的基础上对配方中氮素浓度进行调整,以南农侯喜林教授白菜科研团队的四倍体矮脚黄为实验材料,潮汐式叶菜栽培营养液中NO3-浓度分别为:0,6,12,18,24,30 mmol/L ,共6个不同的处理组,进行潮汐式叶菜栽培实验。结果表明,氮素浓度为18mmol/L时小白菜的地上、地下部鲜重以及可溶性糖、叶绿素等品质指标以及光合生理特性最优。28366 毕业论文关键词:营养液;叶菜;氮素浓度;潮汐式
Optimization of the nutrient solution formula for the tidal leaf vegetables
Abstract: leaf nutrient solution formula in order to optimize the new tide type soilless cultivation facilities, the adjustment of the formula based on leaf nitrogen concentration in Yamazaki nutrient solution formula, and leaf nutrient solution culture corresponding to control, to the south of the agricultural scientific research team, Professor Hou Philodendron cabbage Aijiaohuang as experimental tetraploid materials, tidal nutrient solution in the leaf NO3- concentration were: 0,6,12,18,24,30 mmol/L, a total of 6 different treatment groups were tidal cultivation experiment results showed that the leaf nitrogen; when the concentration of 18mmol/L of Chinese cabbage on the fresh weight and Soluble sugar, chlorophyll and other indicators of quality and photosynthetic characteristics were best
