为了实现环鄱阳湖植棉区棉花生产的绿色轻简高效发展和棉花生产方式转变,于2014-2016年在环鄱阳湖植棉区进行了“棉花与马铃薯连作栽培模式”的试验示范。结果表明:该模式直播棉花籽棉产量为3 453~4 541.1 kg·hm~(-2),马铃薯产量为16.83~28.65 t·hm~(-2)。选用适宜的品种、合适的播种期、合理的密度等技术是确保该模式示范成功的关键技术。试验示范表明棉花与马铃薯连作是一种省工节本、培育地力、调温保墒、高产高效、减少化肥农药投入的轻简栽培新技术。
In order to realize the green and simple and efficient development of cotton production in the cotton planting area of Poyang Lake and the transformation of cotton production methods, a pilot demonstration of “cotton and potato continuous cropping pattern” was conducted in the cotton planting area of Poyang Lake in 2014-2016. The results showed that the yield of cotton seed cotton was 3 453-4 541.1 kg · hm -2 and that of potato was 16.83-28.65 t · hm -2. The selection of appropriate varieties, suitable sowing dates, reasonable density and other technologies are the key technologies to ensure the successful demonstration of this model. Experimental demonstration shows that the continuous cropping of cotton and potato is a provincial section, cultivating fertility, temperature and soil moisture, high yield and efficiency, reduce the investment in fertilizers and pesticides simple and easy cultivation of new technologies.
