马铃薯三级种薯生产力测定试验

Test on the Productivity of Three Potato Seed

通过三级马铃薯种薯同期种植试验,结果表明,同期播种的马铃薯原原种、原种、一级种出苗期和出苗率呈递增状,单株块茎和小区产量呈递增状,生育期天数呈递减状。全面推广普及种植马铃薯一级种薯、原种是马铃薯产业提质增效的关键。

Through the three levels potato seed and simultaneous implantation test,the results show that,at the same time the original species,native species,level 1 Seedling and seedling emergence rate was increased,tuber and tuber yield per plant was increased,and the number of days in growth period decreased. To popularize a potato seed,seed potato industry is the key of quality and efficiency.
