脲醛泡沫基质在番茄种植中的应用研究

Research of Urea Formaldehyde Foam as Substrate in Tomato

以脲醛泡沫栽培基质为研究对象,将其按照不同比例与草炭基质混配使用,研究其理化性质及对番茄生长及产量的影响。结果表明:脲醛泡沫基质不适宜单独进行番茄栽培,需要与草炭基质掺混使用,其与草炭基质的最佳比例为3∶7;按照此比例混配的基质处理,番茄植株生长及产量与完全草炭基质处理无显著差异;安全性方面,脲醛泡沫基质引入番茄栽培,不会增加果实中甲醛含量。

Taking urea formaldehyde foam（UFF）as the research object,by using UFF which mixed in different proportions with turfy soil substrate in tomato cultivation to explore UFF and physicochemical property,the influence of UFF on growth and yield of tomato.The results showed that UFF was not suitable for tomato cultivation alone,requiring the use of mixed with turfy soil substrate.The optimum ratio of UFF to urfy soil substrate propionate was 3∶7.No significant difference was observed on growth and yield of tomato among treatments of turfy soil substrate and UFF with the ratio of 3∶7.The safety aspect,UFF would not increase the content of formaldehyde content in tomato.
