Abstract/Contents:"Along with the planting area of lawn expanding in China, the environmental problem caused by fertilization has attracted much attention now. This study was aimed to analyze the effects of nitrogen application on growth of Lolium perenne and nitrate residue in soil. By pot experiment, nitrogen application took five levels (0, 100, 150, 250 and 350 kg路ha-1路a-1). After fertilization, the growth rate, aboveground biomass, chlorophyll content of L. perenne and nitrate residue in soil were analyzed. The results indicated that, within the range of 0~250 kg路ha-1路a-1 nitrogen application, growth rate, above-ground biomass and chlorophyll content of turf increased with the increasing of nitrogen level, while they all decreased when nitrogen level reached to 350 kg路ha-1路a-1. Nitrate residue in root down layer soil was nearly half of that in root zone layer soil. Nitrate residue of different soil depth was not significantly different from the control (CK) when nitrogen application reached 150 kg路hm-2路a-1, which just could satisfy the turf demand. Nitrate residue in soil increased when nitrogen application exceeded 250 kg路ha-1路a-1 reaching to the highest value 9.01 mg路kg-1 at the rate of 350 kg路ha-1路a-1. Considering the ornamental value and environmental safety, the treatments of urea with concentration of 250 kg路ha-1路a-1 was the best for Northeast area, while it would lead to nitrate leaching to form the potential danger of nitrogen pollution when nitrogen application exceeded 250 kg路ha-1路a-1."
