| 摘 要： | 采用"3414"田间试验方案,研究了沿海地区不同氮磷钾肥配比对杭白菊产量的影响,建立了杭白菊产量(Y)与施氮量(N)、施磷量(P)、施钾量(K)之间的回归方程:Y=702.486+15.289N+9.866P+5.892K-0.310 N2-0.068P2-0.059 K2+0.609NP+0.435NK+0.380PK。据此计算得出杭白菊的最高经济产量为19076.2 kg/hm2,氮、磷、钾肥的最佳施用量分别为N 378.5 kg/hm2、P2O5274.8 kg/hm2、K2O 362.7 kg/hm2。氮肥对杭白菊的增产效应最明显,其次是磷肥。

| Abstract: | Field experiments with "3414" project were conducted to study the effects of different combinations of nitrogen,phosphorus and potash fertilizers application on the yield of Chrysanthemum morifolium in coastal area.Regression equation of its yield to the application amount of nitrogen,phosphorus and potash fertilizers was constructed as follows: Y=702.486+15.289N+9.866P+5.892K-0.310 N2-0.068P2-0.059 K2+0.609NP +.435NK +0.380PK.The maximum Chrysanthemum morifolium yield(19076.2 kg/hm2) was calculated out according to the regression equation,and the corresponding best application amounts of nitrogen,phosphorus and potash were 378.5 kg/hm2,274.8 kg/hm2 and 362.7 kg/hm2,respectively.Nitrogen fertilizer had the greatest effect on the yield,followed by phosphorus fertilizer. |
