【摘要】 以意大利耐抽薹生菜为试验材料,研究了不同倍数营养液浓度处理下[山崎生菜配方的3/4 (3/4s)、1(1s)、2(2s)、4(4s)和6(6s)单位]Hymec膜栽培生菜的情况。结果表明,当营养液浓度增加到6s时Hymec膜栽培生菜的生长才受到一定程度的抑制,但高营养液浓度处理并未显著影响生菜体内营养物质的积累。这种根系非直接接触营养液的栽培方式为利用海水等非传统水资源提供了可行性。更多还原

【Abstract】 To investigate traits of lettuce cultivated by Hymec membrane under five different nutrient solu- tion concentrations (3/4,1,2,4 and 6 units of Yamasaki lettuce nutrient solution formula),the cultural exper- iments of very-late-bohing Italian lettuce were carried out.The results showed that the lettuce growth was inhib- ited to a certain extent when the nutrient solution concentration increased to 6 units,but high nutrient solution concentration did not significantly influence the accumulation of nutrient substance of the lettuce.This cultural mode in which plant roots don’t directly contact nutrient solution makes it feasible to use non-traditional water re- sources such as seawater.更多还原
