您正在将jQuery DOM元素集合转换为字符串。您需要附加新的DOM元素或现有的元素。

$(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
