【Abstract】 The effects of cutting height, cutting frequency and N, P, K fertilizers on the lawn quality were studied by using the fuzzy synthetic judgment and orthogonal regression design (3 2). The results showed that the optimum levels of three factors were 5～7.4 cm for cutting height, 4～6 times per month for cutting frequency and 2.5～3.7 g/m 2 per year for N fertilizer and 1.25～1.85 g/m 2 per year for both P, K fertilizers. The significant correlated regression model between the three factors of establishing turf and the turf quality has been developed.更多还原
