Abstract
Four field experiments about effect of nitrogen application combined with potassium on ginger yield and soil nutrient in Lime concretion black soil district Huaibei plain was conducted for three years. The results showed that applying nitrogen combined with potassium could in crease ginger yield by a big margin. 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. Nitrogen application combined with potassium could efficiently improve the content of organic matter, total nitrogen, available phosphorus, available potassium, slow-available potassium, available calcium and magnesium in soil, decrease the content of nitrate, make soil pH turning to be neutral, and without an obvious influence on the content of total phosphorus and alkali-hydrolyzed nitrogen in soil. The profit-losses status of nitrogen, phosphorus and potassium in Lime concretion black soil showed that nitrogen and phosphorus in soil was surplus plentifully, potassium in soil being deficient seriously when not applying potassium fertilizer, but soil potassium basically being at the situation of profit for the treatments applied with potassium, and it was favorable to maintain and improve soil fertility.
