运用3因素二次回归饱和D-最优设计方案，研究了氮、磷、钾肥对红稗植株分蘖数的影响。结果表明：氮、磷、钾肥对植株分蘖数的影响为磷肥(X2)>钾肥(X3)>氮肥(X1)，从提高红稗植株分蘖数的角度出发，应将磷肥作为首要因素考虑。当植株分蘖数达到最高值时，氮、磷、钾肥的最佳组合分别为：X1编码值为0.19(即氮肥为3.57 kg/667 m2)、X2编码值为0.09(即磷肥为3.26 kg/667 m2)、X3编码值为0.28(即钾肥为3.85 kg/667 m2)。

With the method of the design a three-factor quadratic regression saturation D-optimum,the experiment of effect of nitrogen and phosphorus and potassium on tiller number of bacca sedge was studied. The results indicated that,the phosphorus had more influence on tiller number of bacca sedge than that of potassium and nitrogen,from the perspective of improving tiller number of bacca sedge plants,phosphate should be considered first. When the plants tiller number of bacca sedge reached the highest,the best combination was that the code value of X1 was 0.19(nitrogen was 3.57 kg/667 m2),X2 was 0.09(phosphate was 3.26 kg/667 m2)and X3 was 0.28(potash was 3.85 kg/667 m2).
