t0“Effect of nitrogen application combined with potassium on ginger yield and lime concretion black soil fertility”
e1“applying nitrogen combined with potassium could in crease ginger yield by a big margin”
e2“The output increased by 18.2%～46.9% with the average rate of growth 28.7% for Chai ginger, and 18.2～46.9% and 35.8% for lion head ginger compared ginger yield of treatments which applied with potassium with that of the control”
