旱作区农业节水形式探讨

Discussion on Water-saving Patterns in Arid Agricultural Areas

山西省水资源贫乏,旱作区发展农业要抓好以利用天然降水为重点的节水措施.节水形式有:旱地果园、庭院蔬菜、农地经济作物区集流节水;大面积农业区水土保持措施节水;农业耕作措施节水;覆盖保墒、减少蒸腾技术节水.其中集流节水应作为发展的重点,是我国旱地农业中高投入、高产出的一种较为可行的形式.

Water resources are inadeguate in Shanxi Province. To promote the agricultural development in arid areas, water-saving measures to make use of natural precipitation must be taken. Water-saving patterns include water collection and saving measures for orchards in arid areas, vegetables around court yard, and cash crops in farmland. Soil and water conservation measures for large agricultural area; and water-saving farming measures. Water collection and saving measures should be taken as a main method to increase agricultural income and production.
