Abstract
The successive three-years trial of study on the effect of nitrogen application combined with potassium on ginger yield and nutrient uptake was conducted in six sites in Huaibei ginger production region Shajiang black soil of plain Anhui province from 1999 to 2001. The results showed that K application combined with N could improve ginger output and applying potassium increased yield by 14.9-58.5%.Potassium application improved N content in stem-leaf and P and K content in stem-leaf, ginger tube and total plant, but there was no remarkable effect on the content of nitrogen in total plant. The uptake amount of nitrogen, phosphorus and potassium for stem-leaf, ginger tube and total plant increased along with the rate of K fertilizer application at two N levels. Potassium application combined with nitrogen improved also the content of available P and K in soil substantially, and this was beneficial to maintaining or improving soil fertility.
