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 content of heavy metals in irrigation water was determined by the test and analysis. The content of heavy metals in the matrix was lower than the national control standard. The matrix with the compound had strong nutrient supply ability. On the cultivation of tomatoes, lettuce quality far superior to soil culture, tomato growth period than the soil culture eight to 10 days in advance, of which three formulas of tomato fruit weight, root weight, stems and leaves were significantly different than the soil culture, The yield of lettuce is 47.1% ~ 154.7% higher than that of soil culture.
