The growth character in summer green-turf(July 30—September 30) of Agrostis stolonifera cultivar Yuexuan No.1 under different fertilization frequency were studied through 1-9 days interval adding compound fertilizers (N:P:K=15:15:15)11.11g/m2. The results showed that high fertilization frequency increased the growth of Yuexuan No.1, and increased total N content in clipping of Yuexuan No.1 in green-turf adding compound fertilizer every 2d, 4d and 6d, and decreased the quality in green-turf, while treatment with every 2 days fertilization has excessive growth effect on Yuexuan No.1 in green-turf, and the grass dead after close mowing. There has high turf-quality with even erect growth rate, green color, almost no disease in green-turf of Yuexuan No.1 treated with every 8 days fertilization, and turf-green with every 10 days fertilization has low erect growth rate and low clipping biomass.
