广西发展木薯生产的自然资源优势及对策

Discussion of the natural resources advantages and countermeasures of developing cassava production in Guangxi

木薯是全球年产亿吨以上的七大作物之一,是世界公认的综合利用价值极高的经济作物和重要的工业原料。针对木薯生产对气候条件的要求,论述广西发展木薯生产的气候资源优势,划分广西木薯生产的最适植区、适植区、零星种植区、不可植区。东起梧州,经藤县、桂平、上林、马山、到百色再折向桂西南的大新一线以南地区,为最适植区,该线以北至北起信都、向西经昭平、象州、鹿寨、柳城、宜山、环江、天峨、凤山、凌云、田林再折向北到广西与贵州边界的南盘江一线,为适植区;最适植区和适植区面积占广西总面积的70%以上,宜充分利用这些土地资源合理发展木薯产业,并抓好良种、高产配套技术、减少土壤冲刷等各个技术环节,以取得最佳的经济效益和生态效益。

Cassava was one of the seven crops with the yearly output over one hundred million tons in the world,and it was admitted to be the commercial crop with high comprehensive utilization value and the important industrial material.According to the weather requirements to the cassava production,this paper discussed the weather advantages to develop cassava production in Guangxi,and divided the cassava production areas into the optimum planting area,suitable planting area,sporadic planting area and unsuitable planting area.The region in the south of the line eastward from Wuzhou,through Teng County,Guiping,Shanglin,Mashan to Baise,then turning to Daxin County in the southeast Guangxi,was the optimum planting area.The region in the north of the line from Xindu westward through Zhaoping,Xiangzhou,Luzhai,Liucheng,Yishan,Huanjiang,Tiane,Fengshan,Lingyun and Tianlin,then turning north to Nanpanjiang River at the border of Guangxi and Guizhou Province,was suitable planting area.The optimum and suitable planting areas took up 70% of the total planting area in Guangxi.It was important to take full use of the land resources to rationally develop the cassava industry,and make good efforts to the technology stages such as choosing fine breeds,equipping with high-yield technology and reducing soil washing and so on,in order to obtain the best economic and ecological effects.
