为了给党参专用肥的推广应用提供科学依据,在甘肃省党参主产区渭源县、漳县研究了含腐植酸高塔熔体党参专用肥对党参根部形态特征、产量和品质的影响。结果表明,2个试验区在减少化肥(纯养分)投入27.6%的条件下,施用含腐植酸高塔熔体党参专用肥(N-P2O5-K2O为24-22-8)1 050 kg/hm2较常规施尿素450 kg/hm2、磷酸二铵 900 kg/hm2可使党参干根长分别增加28.13%、11.15%,干根直径分别增加15.09%、15.56%,干根重分别增加19.96%、23.68%,产量分别增加21.26%、17.50%,醇溶性浸出物含量分别增加8.8、10.9百分点,纯收益分别增加42 541、32 456元/hm2。

[Abstract]
In order to provide scientific basis for promotion and application of special fertilizer for Codonopsis piloticus, the effects of special fertilizer containing humic acid and conventional fertilization on the root morphology, yield and quality of Codonopsis pilosula were studied in Weiyuan and Zhang county of Gansu province. The results indicated that compared with conventional fertilization(urea 450 kg/hm2, diammonium 900 kg/hm2), under the condition of reducing fertilizer (pure nutrient) input by 27.6%, the dry root length, dry root diameter, dry root weight, yield, alcohol soluble extract and net profit of Codonopsis pilosula were increased by 28.13% and 11.15%, 15.09% and 15.56%, 19.96% and 23.68%, 21.26% and 17.50%, 8.8% and 10.9%, 42 541 yuan/hm2 and 32 456 yuan/hm2, respectively, by applying High tower melt Codonopsis pilosula special fertilizer containing humic acid (N-P2O5-K2O was 24-22-8)1 050 kg/hm2.
