马铃薯全程机械化高产高效栽培技术分析

为了推动山西省马铃薯产业的进一步发展，方法]通过多年的归纳总结和田间比较试验，结果]系统总结出一套马铃薯全程机械化高产高效栽培技术，包括选地整地、品种选择、种薯处理、播种、田间管理、杀秧收获，新技术共计增收20250元/hm2，其中节省人工费用11250元/hm2，通过增产实现增收9000元/hm2。结论]该技术通过脱毒增产、起垄播种、合理密植、集中施肥、滴灌溶肥、化学防治病虫草害、机械中耕培土、机械杀秧收获，实现了栽培简约、高产高效，良种与良法配套，农机与农艺相结合，显著提高了生物产量与经济产量，并可节省大量人工成本。

Mechanized High Yield Cultivation Techniques for Potato

To improve the development of potato industry in Shanxi, by summing up experiences and field experiment, the authors summarized mechanized high yield cultivation techniques, including land preparation, variety selection, seed treatment, sowing, field management, straw returning and harvest. The techniques could increase the income by 20250 yuan/hm2, save labor costs by 11250 yuan/hm2, and achieve income increase of 9000 yuan/hm2 through yield- increasing. The techniques realized simple cultivation, high yield and effectiveness, the combination of fine seed and fine method, and the combination of agro- machinery and agronomy through virus- free and yield- increasing, ridging seeding, rational close planting, concentrated fertilization, drop irrigation, chemical control of pests and weeds, mechanized intertillage and mechanized harvest. The techniques increased biological and economic yield, and saved labor cost.
