通过探究新型党参专用肥在甘肃党参主产区渭源县党参生产上的应用效果,为新型党参专用肥推广和科学种植党参提供科学依据。2022 — 2023年在渭源县进行了党参专用肥与常规施肥推荐用量的大区对比试验,测定分析对党参干根生长指标、干根产量、浸出物含量、经济效益的影响。结果表明,施用党参专用肥1 050 kg/hm2的处理与常规施肥(基施N 144 kg/hm2、P2O5 150 kg/hm2,追施N 126 kg/hm2)处理相比较,党参干根长、干根直径无显著差异,但平均党参干根单重显著提高了13.59%,平均干根产量显著提高了13.23%,平均党参浸出物含量显著提升了3.373个百分点,纯收益增加93 416元/hm2。因此,建议在甘肃省党参主产区党参生产中宜推广施用新型党参专用肥。

[Abstract]
This study aimed to evaluate the application effect of a new-type Codonopsis pilosula specific fertilizer in Weiyuan County, the main production area of C. pilosula in Gansu Province, to provide a scientific basis for its promotion and rational cultivation. A large-scale comparison experiment was conducted in 2022 and 2023 between the specific fertilizer(1 050 kg/ha) and the conventional fertilization scheme(basal application: N 144 kg/ha, P2O5 150 kg/ha; topdressing: N 126 kg/ha). The effects on dry root growth parameters, dry root yield, extract content, and economic benefits were analyzed. Results showed that while no significant differences were observed in dry root length or diameter, the average single dry root weight increased significantly by 13.59%, the average dry root yield increased by 13.23%, and the extract content improved by 3.373 percentage points. The net income increased markedly by 93 416 Yuan/ha. Therefore, the new-type C. pilosula specific fertilizer is recommended for use in the major production areas of Gansu Province.
