摘要
试验分析测定了有机－无机复配基质栽培所选用的各种配料及灌溉水中重金属含量，基质中的重金属含量低于国家控制标准，复配的基质具有较强的养分供应能力，在这种基质上栽培的番茄、生菜其品质远优于土培，番茄的生育期较土培提前８～１０天，其中３个配方的番茄果重，根重、茎叶重，明显较土培有差异，生菜的产量则较土培提高４７．１％～１５４．７％。
The heavy metal of all kinds of materials and water were analysed,it is much lower than standard controled by contury.Complex substrata have good nutrient suppling ability for plant,quality of tomato and lettuce cultured in three of those substrata were better than those in soil culture,tomato growth period was 8￣10 days earlier,produce;root weigth and leaves and shoot weigth were bigger,produce of lettuce raise about 47.1￣154.7.
