Studies on the Grassland Development in the Forest XII. Effect of nitrogen fertilization on nitrate nitrogen concentration and water soluble carbohydrate content of grasses by growing season and growth stage under shading condition
This experiment was carried out to determine the effects of nitrogen(N) fertilization levels(0. 120, 240 and 360 kg/ha/y) on seasonal nitrate nitrogen(NO3-N) concentration and water soluble carbohydrate (WSC) content of grasses grown under shading cond
