马铃薯种植作业环节多、劳动强度大，而我国马铃薯种植业机械化水平低、机械作业播种质量较差，多数需要人工辅助作业。针对以上问题，研究开发了一种小型多功能马铃薯种植机，可一次作业完成旋耕、施肥、开沟、播种、起垄、铺设滴灌带及覆膜覆土等多工艺联合作业。起垄装置采用液压驱动可调起垄宽度，实现起垄宽度可调，满足不同农艺要求。增设滴灌带铺设装置，可以实现播种同时在垄上膜下铺设滴灌带，有利于节水增产防旱保墒。田间试验检测表明：该机漏播率为1．072％，重播率为1．286％，作业效果良好，各项性能指标均符合《马铃薯种植机质量评价技术规范》标准要求。

Potato planting operation procedure of large labor intensity ,and potato planting mechanization is in a low level , mechanical planting operation of poor sowing quality in China at present , most need manual assistant operation .In view of the above problems , a multifunctional small potato planting machine was designed that can complete the work of rotary tillage , fertilizing , ditching , seeding , soil covering , ridging , laying of drip irrigation belt , film and other operations in once performance .The ridging device driven by hydraulic pressure adjustable ridging width , the realization of ridge width adjustable that to meet different agronomic requirements .Adding drip tape laying device , can realize the sowing in ridge and film laying drip irrigation belt , and is conducive to water saving and production increasing drought prevention .The field production test showed that the average distance deviation rate is 7.258%, the average leakage sowing rate is 1.072%, and the average reseeding rate is 1 .286%.The operation effect is good , and the performance indicators are in line with"technical specifications"potato planting machine quality evaluation standard requirements .
