不同肥料配方对番茄复合基质育苗的影响

Effect of Different Fertilizer on Tomato Breeding by Composite Matrix

为寻求最佳番茄复合基质育苗肥料配方,以复合基质育苗的无土栽培方式为研究内容,在大棚温室条件下,通过在含有不同肥料配方的育苗基质(草炭∶蛭石=2∶1)中,进行番茄穴盘育苗。结果表明:处理2(华南农业大学番茄配方,四水硝酸钙590mg.L-1+硝酸钾404mg.L-1+磷酸二氢钾136mg.L-1+七水硫酸镁246mg.L-1)的幼苗株高、茎粗和干物重3项指标明显优于其它3个处理,其配方是培育番茄穴盘苗的较佳肥料配方。

For the purpose of seeking the best fertilizer formula for tomato breeding by composite matrix, taking the composite matrix seedling soilless cultivation mode as the research content, in greenhouse conditions, through the containing different fertilizer formula of seedling substrate （peat ： vermiculite = 2 ： 1）, tomato plug seedling was eonducted. The results showed that the three indexes of plant height, stem diameter, dry matter weight of treatment 2 （ tomato formula of South China Agricultural University：Ca （ NO3）2·4 H2O 590 mg. L-1 ＋ KNO3 404 mg·L-1 ＋KH2PO4 136 mg.L-1 ＋MgSO4.7H20 246 mg.L-1） were obviously superior to the other three treatments, formula 2 was the better fertilizer formula for cultivating tomato plug seedling.
