    摘要:

    揭示蒙黄芪对3种元素的需求规律,探索氮、磷、钾的最佳施肥量及其配比,为黄芪规范化施肥提供科学依据。在呼和浩特市和林格尔县城关镇马群沟村内蒙古盛齐堂生态药植有限公司药植基地,根据Box-Behnken中心组合设计原理,设计三因素三水平的响应面分析(RSA)试验,研究肥料配施对蒙黄芪产量和品质的影响。结果表明,磷元素对生长期的鲜重影响不显著,而氮肥用量影响显著。调整氮、磷、钾施肥量及配比能够显著提高蒙黄芪产量,当N、P2O5、K2O施用量分别为151.65、174.6、201.3 kg/hm2时,产量达到最大值(8420.33 kg/hm2)。在和林格尔地区,当N、P2O5、K2O的比例为1∶1.15∶1.33时,黄芪药材个体质量优异,产量高,经济效益好。

    Abstract:

    Reval the law of demand of Astragalus membranaceus for the three elements,explore the optimal fertilization amount and ratio of nitrogen,phosphours and potassium,and provide a scientific basis for standardized fertilization of Astragalus membranaceus.In the medical plating base of Shengqitang ecological medicine plant Co. Ltd.,Maqungou village,Chengguan toun,Horinger county,Hohhot city,according to the Box-Behnken center combination design principle,a three-factor three-level response surface analysis(RSA)experiment was designed to study the effect of fertilizer combination on the yield and quality of Astragalus membranaceus.The results showed that P element had no significant effect on the fresh weight during the growing period,while N fertilizer dosage had a significant effect. The yield could increase by adjusting proportioning and dosage of fertilizers,when N,P2O5 and K2O was 151.65,174.6,201.3 kg/hm2,respectively,the maximum yield was 8420.33 kg/hm2. In Horinger county,when the ratio of N,P2O5 and K2O was 1∶1.15∶1.33,the individual quality of Astragalus membranaceus was excellent,the yield was high and the economic benefits were good.
