| 摘 要： | 为了提高春季桑叶1 脱氧野尻霉素（1 deoxynojimycin,DNJ）产量，采用“3414”肥料设计方案，调查氮、磷、钾不同施肥水平对桑叶中DNJ含量的影响。结果表明，氮、磷、钾均对桑树（Morus alba）不同部位叶有较显著影响，随着单因素施肥量的增加，桑叶不同部位叶中DNJ含量也随之增加，在2水平（N2P2K2）时达到最大;进一步以桑叶DNJ产量为目标函数，氮、磷、钾肥的施肥水平为调控因子，模拟其之间的回归关系。结果表明，氮、磷、钾肥的施肥水平及其配比均能显著影响桑叶中DNJ含量。模拟的肥料效应函数表明，桑叶中总DNJ最佳经济产量为23.23 kg·hm 2，推荐施肥指标为N 286.11 kg·hm-2、P2O5 95.22 kg·hm-2、K2O 159.62 kg·hm-2。该最佳施肥通过生产实践证实后，可为DNJ高产桑园建设提供参考。

| Abstract: | In order to increase the 1-deoxynojimycin(DNJ) yield of mulberry leaf in spring,"3414"fertilizer experiment design,the DNJ yield of mulberry leaf as objective function and fertilization level of N、P、K as regulatory factor,was utilized to survey the effects of different proportion of N、P、K on the DNJ yield of mulberry leaf,and simulate regression between them.The results showed the different proportion of N、P、K had significant effect on the DNJ content of mulberry leaf,and the DNJ content were significantly increased with the increase of simple fertilization amount,to the peak at the 2 level(N2P2K2).The optimum recommended fertilization parameters and the optimum economical yield were respectively achieved by the fertilizer effect function,286.11 kg·ha-1 N、95.22 kg·ha-1 P2O5、159.62 kg·ha-1 K2O and 23.23 kg·ha-1.The optimum fertilization design after conformation in productive practice would provide references on the high yield and qualities of mulberry leaf in Sichuan hilly area. |
