锌硼钼配施对北柴胡产量及柴胡皂苷a,d含量的影响

采用"3414"肥料效应试验方案,对北柴胡进行不同配比的锌硼钼配施处理,通过测定北柴胡干物质积累量和柴胡皂苷a,d含量动态变化以及北柴胡产量,考察不同浓度的锌(Zn)硼(B)钼(Mo)配施对北柴胡产量及柴胡皂苷a,d含量的影响。结果发现适宜配比的锌硼钼配施对北柴胡干物质积累及分配有积极的调节作用,处理Zn2B2Mo3不仅能促进干物质积累,还利于干物质有效地向地下部分转移;一定范围内,单施Zn,Mo肥均能够增加北柴胡根部的产量,处理Zn2B2Mo1的产量为所有处理中的最大值。回归分析结果表明:适当调整微肥配施,按Zn 48.45 g·hm-2,B 355.05 g·hm-2,Mo 86.40 g·hm-2的配方,北柴胡能够获得3 313.05 kg·hm-2的产量;处理Zn2B3Mo2的锌硼钼配比最有利于北柴胡根部柴胡皂苷a,d总量的增加,回归分析结果表明:最佳微肥施肥量为Zn 36.15 g·hm-2,B 343.05 g·hm-2,Mo 106.35 g·hm-2,此配方下,柴胡皂苷a,d总量能够达到1.23%。该研究首次发现适宜配比的锌硼钼配施能够提高北柴胡的根部产量,并能够促进柴胡皂苷a,d的积累。

Effect of combined application of zinc, boron and molybdenum on yield and saikosaponin a, saikosaponin d contents of Bupleurum chinense

This research use "3414" fertilizer effect experiments to handle zinc, boron and molybdenum trace element fertilizer, determined the dry matter accumulation and content of saikosaponion a and d, to investigate the different ratio of zinc, boron and molybdenum on yield and saikosaponin a, saikosaponin d contents of Bupleurum chinense. Found The suitable ratio of zinc, boron and molybdenum play an active role on dry matter accumulation and distribution, the treatment Zn₂B₂Mo₃ is the best one to promote the dry matter accumulation and transfer to the underground part; in a certain range, only use zinc or molybdenum can promote the yield of B. chinense, the yield of treatment Zn₂B₂Mo₁ is the highest one. According to the results of regression analysis: in accordance with Zn 48.45 g·hm^-2, B 355.05 g·hm^-2, Mo 86.40 g·hm^-2, can obtain the yield with 3 313.05 kg·hm^-2; the treatment Zn₂B₃Mo₂ is most effective to promote the total saikosaponin a and d accumulated, according to the results of regression analysis: in accordance with Zn 36.15 g·hm^-2, B 343.05 g·hm^-2, Mo 106.35 g·hm^-2, the content of total saikosaponin a and d can reach 1.23%. This research first discovered the suitable ratio of zinc, boron and molybdenum can promote the yield and saikosaponin a, saikosaponin d contents on B. chinense.
