摘要
我国丘陵薄地甘薯种植面积为2333～2667khm2,但由于田块小、地形复杂、土壤条件差、种植制度多样、经营较分散,给该地区的生产机械化发展带来了很大困难和许多制约因素;本文在分析丘陵薄地甘薯生产分布、种植概况并结合研究提出的国内甘薯生产机械三种发展模式的基础上,提出适宜丘陵薄地社会、经济、自然条件的五条发展建议和对策,并就不同坡度、田块大小、顺坡方向长短、机耕道建设、经营规模等提出适宜的机械作业模式。
The acreage of sweet potato in hills poor land of China is about 0.0233-0.06 billion ha, but because there are some problems such as the small plots, complex terrain, poor soil conditions, the variety of cropping systems and more decentralized business in these areas, the developing of the production mechanization in the region faced with many difficulties and constraints. On the basis of analyzing production and distribution, planting overview in hills poor land, and combining with three sweet potato production mechanization development model in China, the paper study and propose five development proposals and countermeasures appropriated to community, economic and natural conditions, and make appropriate mechanical operation mode about different slopes, the size of plots, the length of the downslope direction, farm track construction, scale of operation and so on.
