在年降水量300mm左右的半干旱山地雨养农业区,采取挖建集流水窖、合理补灌、扩大秋作物种植面积、推广地膜覆盖技术等措施,将工程设施集水与农艺措施节水有机地结合起来,有利于提高天然降水的有效利用率,大幅度的增加作物产量,促进农业生产和农村经济的发展。
In the semi-arid mountain rainfed farming area where the annual precipitation is about 300mm, measures such as excavation and construction of cased water cellars, rational irrigation, expansion of planting area of autumn crops and popularization of plastic film mulching are adopted to collect water and agronomic measures of engineering facilities In combination, it is beneficial to improve the effective utilization of natural precipitation, increase crop yield significantly, and promote the development of agricultural production and rural economy.
