| 摘 要： | 运用三元二次回归正交组合设计研究N,P,K施用量及其配比对白芷早期抽苔的影响.结果表明:白芷的早期抽苔率与N,P,K的供应密切相关.白芷抽苔率随N,P用量的增加而增加,随K用量的增加而减少.当P,K用量为零水平,N用量为24g/m2,白芷抽苔率最高,达9.7%;当N,K用量为零水平,P用量为10.5g/m2,白芷抽苔率最高为8.5%;N,P用量为零水平,随着K用量增加,白芷抽苔率由10%下降到6.4%.

| Abstract: | The combining quadratic regression orthogonal design with 3 factors was employed to study the effects of N,P and K rates and their proportions on curtail early bolting of Angelica dahurica var.formosana.The results showed that the bolting rate and yield of A.dahurica was closely associated with NPK supply.The rate of early bolting of A.dahurica increased with N and P rates and decreased with increasing K application.With no PK application,the highest bolting rate(9.7%) was recorded with an N rate of 24 g/m2... |
