%X China is the country having many plateaus in the world. On the plateau surface, the land resource is abandant, but the agricultural development is puzzled by long term drought and water shortage. The current productive level here is low. During the period of the eighth five year plan, the adoption of semi removable spray irrigation has succeded. The unit area grain yield can increase from present 750 kg/ha to 5 250 kg/ha. The investment cost can be returned in one year in respect of most grain varietis. Enomous potentials of grain yield in the area are of special significance to the short supply trend of China's grain production.
