新疆北疆沿天山一带地区,土地广阔、光热资源好,无霜期150—180天左右,适宜发展农业。唯气候干旱,年蒸发量达1600mm以上,而降水量只有200mm左右,干燥度8以上,属于“没有灌溉即无农业”的干旱农业区。多年来虽然兴修了许多农田水利设施,仍不能满足灌溉要求,水土不平衡是农业生产中的突出矛盾。如石河子地区现有耕地250多万亩(规划面积295万亩),但由于灌溉水量不足,每年只能播种220—230万亩左右,几乎每个单位都要分摊10%左右的短期全休闲地,影响农业生产发展。
Xinjiang’s northern region along the Tianshan area, vast land, light and heat resources, frost-free period of 150-180 days, suitable for the development of agriculture. Only the arid climate, the annual evaporation of 1600mm above, and the precipitation is only about 200mm, the dryness of more than 8, are “no irrigation or agriculture” in arid agriculture. Although many irrigation and water conservancy facilities have been built over the years, the irrigation requirements still can not be met. The imbalance of water and soil is the prominent contradiction in agricultural production. For instance, there are more than 2.5 million mu of cultivated land in the Shihezi region (with a planned area of 2.95 million mu). However, due to the shortage of irrigation water, only about 2.2-2.3 million mu of seeding can be planted every year. Almost 10% of short-term all-leisure land , Affecting the development of agricultural production.
