摘要
甜高粱是集生物能源、酿酒、饲料等多用途的一种抗盐碱、耐贫瘠、高光效的C4作物。在粮棉争地的大背景下,为了解甜高粱在江苏沿海盐碱地适应性情况,本研究引进3个甜高粱品种进行示范种植。结果表明:引进的3个甜高粱品种中相对早熟的是雅津201,糖锤度相对较高的是雅津71,雅津71、雅津95秸秆产量相对较高、耐盐碱性强、长势长相好、抗病虫性突出,但株高相对较高,且生育期较长。故需引进早熟、株高适中的品种,种植行向也应改变,同时后期加强施肥、培土等。初步形成江苏沿海盐碱地的甜高粱育种目标并完成开发产业链的初步探索。通过引进合适的品种并结合栽培技术集成在江苏沿海盐碱地种植甜高粱是可行的,产业链开发也将有广阔前景。
Sweet sorghum was a C4 plant with salt and barren tolerant,high photosynthetic efficiency and multipurpose such as biological energy,brewing and feed. Nowadays,under the background of contending soil between foodstuff and cotton,three sweet sorhhum cultivars,i.e. Yajin 201,Yajin71 and Yajin 95 were introduced in order to investigate adaptability of sweet sorghum in saline land of coastal area in Jiangsu Province. The primary results indicated that among three sweet sorghum cultivars,Yajin 201 had relative early maturity,Yajin 71 had relatively high in sugar brix,Yajin 71 and Yajin 95 had relatively high biomass,salt tolerance and pest resistance; However,their plant height was relatively high and maturity was long. It was suggested that sweet sorghum cultivars with early maturity and proper plant height may be considered to introduce in coastal area of Jiangsu Province. Cultivation technique may focused on plant density（ 7000 plants per 666.7m2） and fertilizer dressing in late stage. Based on the observation of adaptability of sweet sorghum,its breeding objective and the exploration of industry chain in coastal area of Jiangsu Province was preliminarily constructed. It is feasible to develop sweet sorghum by introducing appropriate cultivars combined with integration of cultivation techniques,its industrial chain development would be also promising.
