1992年我县带状种植已遍及15个乡镇,种植面积达到16万亩。实践证明,发展间作套种及其带状种植,是我县灌溉农田粮食单产再上新台阶、实现吨粮田的有效措施,也是人均耕地少的地区增产增收的良好途径。一、充分利用生长季节及其光热水土资源民勤县位于河西走廊东北部,海拔1200~1500米。年日照时数3028小时。全年太阳辐射量为137.2千卡/平方厘米,≥0℃积温3649℃,≥10℃积温3149℃。年降雨量110毫米,且多集中在7~9月份。无霜期157天。历年形成的多种一熟制光热资源丰富有余,小麦收获后到初霜降临前,约70~85天生长期
In 1992, our county banded planting has covered 15 townships and the planting area reached 160,000 mu. Practice has proved that the development of intercropping intercropping and its strip planting is an effective measure for grain yield per unit area in irrigated farmland in our county to realize the cultivation of tons of grain and is also a good way to increase production and increase incomes in areas with arable land per capita. First, make full use of the growing season and its hot and cold water and soil resources Minqin County is located in the northeast Hexi Corridor, 1200 ~ 1500 meters above sea level. Year sunshine hours 3028 hours. Annual solar radiation 137.2 kcal / cm2, ≥ 0 ℃ accumulated temperature 3649 ℃, ≥ 10 ℃ accumulated temperature 3149 ℃. Annual rainfall of 110 mm, and more concentrated in the 7-9 months. Frost-free period of 157 days. Over the years formed a variety of cooked light and heat more abundant resources, after the wheat harvest to the first frost, about 70 to 85 days of growth
