摘　　要：以2种果型番茄为试验材料,通过在育苗基质中添加3种不同天数缓释尿素,研究其对番茄幼苗生长的影响,筛选出适合番茄穴盘育苗的基质配方,为番茄集约化育苗过程中缓释尿素的科学合理使用提供技术参数。结果表明,“皖杂20”番茄的最佳缓释尿素基质育苗配方为60 d缓释尿素添加1粒,即1 L“兴兴向农牌”育苗专用基质添加60 d缓释尿素0.449 g,此时壮苗指数为0.577。“黄樱桃”番茄的最佳缓释尿素基质育苗配方为60 d缓释尿素添加2粒,即1 L“兴兴向农牌”育苗专用基质添加60 d缓释尿素0.898 g,此时壮苗指数为0.757。In this experiment,two kinds of fruit tomato were used as experimental materials.By adding three kinds of slow-release urea for different days to the seedling substrate,the effect on the growth of tomato seedlings was studied,and the matrix formula suitable for tomato plug seedling was selected,so as to provide technical parameters for the scientific and rational use of slow-release urea in the process of intensive seedling raising of tomato.The results showed that the best slow-release urea matrix seedling formula of‘wanza 20’tomato was to add 1 capsule of slow-release urea in 60 days,and the strong seedling index was 0.577.The best slow-release urea matrix seedling formula of‘yellow cherry’tomato was to add 2 slow-release urea in 60 days,and the strong seedling index was 0.757.
