曲沃县位于晋南临汾盆地南端,气候温和,无霜期190天左右,适宜种棉。棉田面积约占全县总耕地的1/3,正常年份平均亩产皮棉五、六十斤。近年来先后引进早熟、高产、优质的黑山棉、中棉所10号等棉花优种,进行麦茬复播试验,一般亩产皮棉40斤以上,麦、棉总收入高于麦、棉单作田。开始试种时,有人说:“立夏种棉花,有苗没疙瘩”,担心棉花没收成,小麦也减产。实践证明,复播棉花在我县可行。从生育期来看,黑山棉和中棉所10号为早熟和特早熟品种,生育期120天左右。6月上旬麦田套种,到10月20日左右早霜来
Quwo County is located in the southern tip of Jinnan Linfen basin, a mild climate, frost-free period of about 190 days, suitable for cotton. The area of cotton field accounts for 1/3 of the total cultivated land of the county, and the average annual output of lint cotton in the normal year is five or sixty catties. In recent years, it has introduced premature, high-yield and high-quality Montenegro cotton and Zhongmian No. 10 cotton superiority for rewetting stubble. Generally, more than 40 pounds of lint per mu is produced. The total income of wheat and cotton is higher than that of wheat and cotton alone. At the beginning of the trial planting, someone said: “The establishment of summer cotton, seedling no pimples”, worried about cotton forfeiture, wheat also cut. Practice has proved that multicast cotton feasible in our county. From the growth point of view, Montenegro cotton and cotton in the No.10 early and special precocious varieties, growth period of about 120 days. In early June wheat field interplanting, early frost to about October 20
