田间试验观察了3种生物有机肥对马铃薯产量和品质的影响。结果表明，马铃薯施用GSN-1配方生物有机肥折合产量最高，为39 961.9 kg/hm2，较不施生物有机肥增产7 885.7 kg/hm2，增产率24.58%；施用GSJ-1折合产量37 061.9 kg/hm2，较不施生物有机肥增产15.54%。施用生物有机肥后，块茎中维生素C、粗淀粉、粗蛋白含量分别提高1.8%～15.3%、11.3%～13.4%、4.9%～7.2%。

Field trials was observed to evaluate the influence of three kinds of biological organic fertilizer on yield and quality of potatoes.The results shows that three kinds of biological organic fertilizer could significantly improve the yield and quality of potatoes.The highest is GSN-1， and yield is 39 961.9 kg/hm2， the second one is GSJ-1， the yield is 37 061.9 kg/hm2， compare with no biological organic fertilizer increase 24.58% and 15.54% respectively . The vitamin C， crude starch and crude protein of potatoes tuber could increase 1.8%~5.3%， 11.3%~15.3%， and 4.9%~7.2%， repectively .
