麦、棉都是国计民生的战略物资,又是冀中南地区的优势作物,同步发展棉、麦生产,实现粮棉双丰收,历来是这里广大人民的迫切要求。根据棉花、小(大)麦的生育生理特性,扬长避短,在冀中南的特定自然条件下,优选出适宜品种和相应的配套栽培技术,以达到内在因素和外在环境条件的统一,就能改棉花一年一熟为麦棉一年两熟。一、效益。 1985年以来,我们连续进行了麦棉满幅复种的定位试验。通过详细统计不同种植制度的物料投入和产出,全面核算其各项经济指标,确定出取得的效益。 1,社会效益:从产量看,小(大)麦复种棉花与单作棉花比较,少收1公斤籽棉,能换取12.9公斤小麦或9.0公斤大麦;与小麦、玉米复种比较,每增收1公斤籽棉,只少收0.24公斤小麦和1.6公斤玉米,或0.43公斤大麦和1.69公斤玉米。因此,无论棉区或粮区,改种一定面积的麦棉满幅复种后,都能取得麦棉
Both wheat and cotton are the strategic materials for people’s livelihood and the dominant crops in central and southern regions of the country. The simultaneous development of cotton and wheat production and the double harvest of grain and cotton have always been the pressing demands of the broad masses of people here. According to the reproductive physiological characteristics of cotton and small (large) wheat, we should select the suitable varieties and corresponding cultivation techniques under the specific natural conditions of Jizhong South in order to achieve the unification of internal factors and external environmental conditions, Cotton is cooked twice a year for the cotton crop a year. First, the benefits. Since 1985, we conducted a continuous positioning test of full-scale cotton and cotton seed multiplication. Through detailed statistics of material inputs and outputs of different cropping systems, the various economic indicators are fully accounted for and the benefits obtained are determined. 1. Social Benefit: According to the output, the small (big) wheat multiple cropping cotton, compared with single crop cotton, receives less 1kg seed cotton and can exchange 12.9kg wheat or 9.0kg barley. Compared with the wheat and corn cropping, each additional 1kg seed cotton , Only received less 0.24 kilograms of wheat and 1.6 kilograms of corn, or 0.43 kilograms of barley and 1.69 kilograms of corn. Therefore, regardless of the cotton area or grain area, a certain area of wheat replanting a full area after multiple cropping, can obtain wheat
