Effect of nutritional condition on N2O emission by crop seedlings——a sand liguid cross culture study

Abstract

Abstract: With separated compartment culture technique, the study confirmed that N₂O in soils has a great interference on the measurement of N₂O emitted directly by some plants such as maize and sorghum. The interference can be effectively eliminated by means of sand liquid cross culture technique. With this technique, the intensity of N₂O emitted directly by seedlings of both soybean and maize is accurately determined, and the correlations between Nand Pnutritions on the one hand and N₂O emission and NO₃^--N concentration of crop seedlings on the another hand are obtained.

Key words: N₂O emission, Plants, Effect of nutrition, nitrogen, biochar, tree peony, translocation, seed quality, accumulation
