| Abstract: | The preliminary results with detached leaves and seedlings of corn, soybean and sorghumfrom pot and field experiments indicate that inorganic nitrogen supply can significantly enhance the N2O emission and NO3 concentration in plants in the case of phosphorus deficiency and of less light, but phosphorus Supply and sunlight condition can markedly reduce the N2O emission and NO3 concentration in the plants. It's concluded seemed thatthe N2O emission is a kind of physiological protection to avoid NO3 accumulation in plantswhen nitrogen metabolism in plants is in disorder and mineral nitrogen is in over supply. |
