摘要: 我国是世界上高原众多的国家,高原面上土地资源丰富,而长期干旱缺水困扰高原农业的发展,当前生产水平低。“八五”期间采用半移动式喷灌获得成功,粮食单产可从现在的每公顷750kg,提高到5250kg,大多数作物品种一年便可收回投资成本。巨大的增产潜力,对于我国粮食生产供应态势趋紧具有特殊意义。

关键词: 节水, 低耗, 高产, 高效, 灌溉方式, 半移动式喷灌

Abstract: 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.

Key words: saving water, low consumption, high yield, high efficient irrigation way, semi removable spray irrigation
