膜上精量播种装备研究现状及发展趋势

Present Research Status and Development Trend of Over-Film Precision Seeding Equipment

我国西北部以及西南丘陵地区秋冬季节干旱缺水,农作物产量低且不稳定,这一问题严重制约当地农业生产发展和社会经济发展。如何减少农田水分流失、高效利用天然降雨成为我国旱区农作物种植的关键难题,推广膜上精量播种技术是实现我国西南、西北等旱作农业发展的重要途经之一。因此,在分析国内外农作物种植铺膜精量播种机械技术基础上,阐述现阶段膜上播种装备的研究进展及存在问题,并展望膜上精量播种机械化的发展趋势,为膜上精量播种进一步发展提供参考。

Drought and water shortage,low and unstable crop yield in autumn and winter in northwest China and southwest hilly areas seriously restrict its agricultural production.How to reduce farmland water loss and make efficient use of natural rainfall has become a key problem in crop planting in dry areas of China.Popularizing precision sowing technology on film is one of the important ways to realize the development of dry farming in northwest China.Therefore,on the basis of analyzing the mechanical technology of precision sowing on film for crop planting at home and abroad,this paper expounds the research progress and existing problems of precision sowing equipment on film at present,and looks forward to the development trend of precision sowing mechanization on film,providing reference for the further development of precision sowing over film.
