The amount of volatilization is large because the urine cord cannot reach the soil layer with the fixed depth when the water is insufficient.
滥水量不足,尿索随水移动达不到定深度的土层,挥发量就大;

Too much water, most fertilizers with water infiltration deep, crops can not be well absorbed and utilized.
消水过多,大部分肥料随水渗人深层,作物也不能很好地吸收利用。

具体做法是,在水稻分蘖末期,结合烤田,当田面出现微小裂缝时撒施氮肥,再淄水把肥料带人士层中,从而达到氮肥深施的目的。

In addition, when nitrogen fertilizer is used as topdressing for rice fields, the surface water can be scattered dry first to keep the surface moist, and the fertilizer can be withdrawn immediately.
