问:于播种后,间隔一定天数追施肥料,这种施氮方式是否可以模拟? 答: 可以,但需要自定义。具体操作方法见下: It is a top up rule meaning that it will determine the amount to apply to keep the amount of N at a threshold (the value specified on the line “Amount of N required in top 3 layers (kg/ha) : “). 请复制以下内容,粘贴到paddock节点。这样模拟树就增加了新组件,该组件可以实现设置施肥料和间隔天数。
