摘要/Abstract

摘要： 为筛选出适宜内蒙古地区叶菜水培的营养液配方,以美国大速生(生菜)为试验材料,以霍格兰-阿侬1/4浓度、日本山崎(莴苣)、华南农业大学叶菜(B)3个营养液配方为试验处理,研究不同营养液配方对生菜生长的影响。结果表明:霍格兰-阿侬1/4浓度配方处理下,植株地上部分鲜重最重,达47.35g/株,分别高于日本山崎(莴苣)、华南农业大学叶菜(B)10.3,11.3g/株。霍格兰-阿侬1/4浓度配方处理下,植株叶片叶绿素相对含量最高,达21.73,显著高于华南农业大学叶菜(B)17.91。霍格兰-阿侬配方、日本山崎(莴苣)在pH值较高的情况下,EC值稳定性高,适合生菜生长。由此可得,霍格兰-阿侬1/4浓度配方为内蒙古地区栽培生菜最适宜的营养液配方。该研究结果为北方硬水地区营养液栽培叶菜提供了有益参考。

Abstract: The goal was to study the growth of lettuce in different nutrient solutions and select the optimum nutrient solution which will be used in Inner Mongolia,with 1/4 Hogland and Arnon,Nutrient solution formula,Leaf vegetables of South China Agricultural University(B)as the three nutrient solution treatments were set using lettuce as material.The results showed that use of 1/4 Hogland and Arnon produced the greatest fresh weight of above ground,up to 47.35 g/plant,which was,respectively,10.3 g/plant higher than Nutrient solution formula and 11.3 g/plant higher than Leaf vegetables of South China Agricultural University(B).Relative Chlorophyll content using 1/4 Hogland and Arnon was 21.73,which was significantly 17.91 higher than the chlorophyll content using Leaf vegetables of South China Agricultural University(B).In alkaline conditions,Nutrient solution had the stable EC of 1/4 Hogland and Arnon,which was suitable for the growth of lettuce.Therefore,1/4 Hogland and Arnon is the most suitable nutrient solution for Inner Mongolia.The results provide a useful reference for the cultivation of leafy vegetables in nutrient solutions for the hard water areas of northern China.
