Potato mechanized planting technology in hilly and mountainous areastaking Weining County，Bijie City，Guizhou Province as an example

Potato is one of main food crops, and hilly and mountainous areas are important bases for potato cultivation in China．There is a large space for yield increase．Terrain and landforms in hilly and mountainous areas are complex, and there are few practical tools available, which has prevented full mechanization of potato cultivation．In recent years, with highly integrated development of agricultural machinery and agronomy, Weining County has studied a set of potato mechanized planting technology, which has been recognized and promoted by planting professional cooperatives, agricultural machinery professional cooperatives, and farmers．Potato yield has greatly increased．However, high requirements for mechanized planting technology, lack of suitable machinery for hilly and mountainous areas, lack of large-scale planting, inability of planting agronomy to meet needs of farmers, and insufficient technical strength of agricultural machinery have troubled entire process of potato mechanized planting in Weining County．Based on practical production experience and research, countermeasures and suggestions for fully mechanized potato cultivation in hilly and mountainous areas have been proposed．
