摘　　要：为了探索适合山西温室番茄无土栽培的营养液配方,研究了不同营养液配方与浓度的营养液对番茄幼苗生长的影响。结果表明,施用荷兰番茄配方的营养液植株生长发育较好,其次是山东农业大学番茄营养液配方和华南农业大学番茄营养液配方,最后是山崎番茄营养液配方。在所有的处理中,标准浓度的营养液对植株株高、茎粗、鲜重、干重和叶面积的增长方面效果最好,其次1/2倍的,最后是1/4倍的,3个浓度的处理间差异极显著。施用荷兰番茄营养液配方标准浓度的营养液与施用其它配方的营养液相比,番茄幼苗的生长期为73 d,比其它配方处理缩短了8 d。The effect of nutrient solution with different composition and different concentrations on the growth of tomato seeding was studied in the experiment in order to select the suitable nutrient solution composition of soilless cultivation for tomato in greenhouse in Shanxi.The result indicated that the growth and development of tomato plant supplied with nutrient solution of Holland tomato composition was the best.The nutrient solutions developed by Shandong Agricultural University and Huanan Agricultural University were in next orders.The last was Shanqi tomato nutrient solution.The growth rate of plant height,stem diameter,weights of fresh and dry matter,and leaf area were the highest when tomato was supplied with nutrient solution of one multiple standard concentration.The following were them of 1/2 multiple and 1/4 multiple.The treatments of three concentrations were extremely significant.The growth period of tomato seedling supplied with one standard concentration of nutrient solution of Holland tomato composition was shorter,which were 73 days,than these supplied with other nutrient solutions.The growth period of tomato seedling was shortened by 8 days.
