| 摘要: |
| 本研究采用"3414"不完全正交回归设计方案,分析了氮、磷、钾肥不同水平对苦豆子产量及苦参碱含量的影响。结果表明:1)N+P+K、N+P、N+K三种施肥组合与苦豆子产量相关性最大,单施N、P、K和P+K对其影响较小。2)复合施肥N 、P2O5 、K2O 用量分别为134.85、91.0、59.9 kg/hm2时苦豆子产量最高,约为2 016.75 kg/hm2。3)综合考虑各药用部位苦参碱含量,施肥量的最优范围为N 125~180 kg/hm2、P2O5 80~90 kg/hm2、K2O 10~45 kg/hm2。 |

| Abstract: |
| The ‘3414’ design was used to study the effects of different levels of nitrogen(N),phosphorus(P),and potassium(K) on the yield and matrine content of Sophora alopecuroides L.The results showed that:1) three fertilization combinations (N+P+K,N+P and N+K) have the largest correlationships with the yield of Sophora alopecuroides L.,single application of N,P,K,and P+K have less influence; 2) according to the fertilization mathematic model,the optimum fertilization for N,P,K based on the largest yield which can reach to 2 016.75 kg/hm2 were 134.85,91.00 and 59.90 kg/hm2 respectively; 3)The optimum fertilization for N,P,K based on the matrine content of different parts should be defined as N 125-180 kg/hm2,P2O5 80-90 kg/hm2、K2O 10-45 kg/hm2. |
