针对南方红壤低丘岗区农田种植业结构不合理 ,效益低等问题 ,以市场为导向 ,调整“粮—经—饲”种植结构 ,引进、筛选、培育新品种 ,优化种植制度。稻田和旱地改制 ,引进扩种饲料玉米、特用玉米、烤烟和其他经济作物 ,红壤旱地重点发展以春玉米为主裁作物的多元多熟种植模式 ,对部分中低产稻田进行改制 ,适当调减早稻面积 ,尽快淘汰早籼稻、大力发展优质稻、饲料稻和玉米 ,大力发展适销对路的特色经济作物和高价值作物 ,如烤烟、西瓜等。研究提出了本区高效种植结构调整的重点及作物优质、高产配套技术并在试区示范推广 ,促进了红壤丘岗区种植业三元结构优化和该类型区经济、生态和社会效益协调发展 In view of the unreasonable farmland structure and the low benefit in the hilly area of ​​the southern red soils, the market-oriented planting structure of “grain-economy-feed” was adjusted and introduced, selected, cultivated and the planting system optimized. Paddy field and dry land reform, the introduction of expanded fodder corn, maize, flue-cured tobacco and other cash crops, red soil dryland focused on the development of multi-cropping of spring maize crop multi-plantation model, part of the low-yielding rice fields restructuring, appropriate reduction Early rice area, early indica rice out as soon as possible, vigorously develop high-quality rice, forages and corn, to develop marketable specialty cash crops and high-value crops such as flue-cured tobacco, watermelon and so on. The study put forward the key points of high-efficient planting structure adjustment and the high-yielding and high-yielding techniques of crop planting in this area and demonstrated and popularized in the test area, promoted the optimization of ternary structure of planting industry in hilly area of ​​red soil and the coordinated development of economic, ecological and social benefits in this type of area
