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 cultivation substrate as the research object, it was mixed with peat matrix according to different proportion to study its physicochemical properties and its effect on tomato growth and yield. The results showed that urea-formaldehyde foam matrix was not suitable for tomato cultivation alone, and should be blended with peat matrix. The best ratio of peat matrix to peat matrix was 3: 7.Furthermore, There was no significant difference in peat matrix treatment. In terms of safety, urea-formaldehyde foam matrix was introduced into tomato and did not increase the content of formaldehyde in fruit.
