您正在将jQuery DOM元素集合转换为字符串。您需要附加一个新的DOM元素或现有的一个克隆。

$(document).ready(function(){ 
    $("a.add_more").on("click", function(){ 
     var closest_td = $(this).closest("td"); 
     var select_tag = closest_td.find("select:first"); 
     closest_td.append("<br>").append(select_tag.clone()); 
    });//add_more.on click 
});//dom ready
