摘要
运用三因素饱和最优设计与灰色局势评价方法,通过盆栽试验,研究了适合于科尔沁沙地土壤的冷地型草坪基肥的氮、磷、钾营养元素的配比方案。结果表明,本试验的土壤条件,N,P和K3种营养元素的最佳配比是N∶P2O5∶K2O为9.91∶7.78∶4.63,施肥量为108g/m2,其中,硫酸铵+尿素38.23g/m2,过磷酸钙59.83g/m2,硫酸钾9.96g/m2。
The optimum combination program of N, P, and K in the basic fertilizer on the cold type turf was studied by using three factors saturated optimum design and gray game decision method. The result showed that the optimum combination of N, P, K mixed fertilizer in the basic fertilizer of the turf was N∶P_(2)O_(5)∶K_(2)O=(9.91∶ 7.78∶ 4.63). And the optimum amount of fertilization is 108 g /m^(2) under the environment condition of this experiment.
