農作物豐產的許多因素中，水和肥是其中兩個重要的因素。俗話說得好，“有收無收在於水

，收多收少在於肥”。zheshuoming，nengfoujishiguanshui，baozhengzuowuduishuifendexuqiushizuowushengchangdexianzhiyinsu。tongyang，nengfouhelishifeijishimanzuzuowuduiyangfendexuyaoshijuedingzuowuchanliangdeguanjian。kejian，shifeiheguanshuizheliangxiangcuoshizainongyeshengchanshangshiduomedezhongyao。

專家提示：

1、在一定的範圍內，增施肥料能夠提高作物產量，但進一步提高產量還需要其他措施的配合。

2、施肥與灌水相結合能使有限的肥料發揮最大的增產效益，原因是利用水肥結合產生。
