| 摘 要： | 由于干旱使华北地区作物生态环境失去了平衡,粮食产量也不稳定,实践证明,使用含有镧系元素的抗旱肥料,达到了抗御冬旱、保苗、增产的效果。在华北地区及黄河中下游半干旱-半湿润地区使用抗旱肥料,具有广阔的前景。

| Abstract: | Entironment of crops in North China can't maintain in a state of equilibrium owing to drought, leading to instability of grain yield. Practice indicates that crops, while fertilized with lanthanide elements- containing drought - resistant fertilizers, can fight a winter drought, keep a full stand of seedlings and hence increase yield. Therefore, popularization of drought - resistant fertilizers in the semi - dry or semi - wet areas in North China will get a vast range of prospects. |
