一、棉花啤酒大麦两熟栽培的可能性邯郸地区全年≥0℃积温为4,800—5,000℃,保证率80%的积温为4600—4800℃。当地春播棉花所需≥10℃活动积温,从四月二十日到十月二十日共约4,000℃。因此,如果一年一作单种棉花,将有适宜冬小麦生长的≥0℃活动积温800—1,000℃不能充分利用。如果一年两作棉麦两熟,两茬共需≥10℃活动积温5,300—5,500℃,即使选用早 First, the possibility of cotton barley two-crop cultivation Barley throughout the year ≥ 0 ℃ accumulated temperature of 4,800-5,000 ℃, the guarantee rate of 80% of the accumulated temperature 4600-4800 ℃. Local spring cotton ≥10 ℃ active accumulated temperature, from April 20 to October 20, a total of about 4,000 ℃. Therefore, if a single year of cotton, there will be suitable for winter wheat ≥ 0 ℃ activity accumulated temperature 800-1,000 ℃ can not be fully utilized. If cotton and wheat two crops for two years a year, two stubbles need ≥ 10 ℃ active accumulated temperature 5,300-5,500 ℃, even if the selection of early
