摘要: 为筛选高效拌根剂配比,探究其对滇黄精(Polygonatum kingianum Collett & Hemsl.)生长、品质及土壤理化性质的影响,以两年生滇黄精种苗为材料,将9种杀菌剂复配为4种拌根处理(A1至A4)及对照(CK)。结果表明,与CK相比,拌根剂处理显著提高了滇黄精出苗率、存苗率及抗病能力。其中A1处理(四霉素80%+福美双5%+克菌丹15%)效果最优,出苗率和存苗率分别为95.75%、95.25%,8月与9月根腐病发病率(1.25%、4.75%)显著低于CK(34.00%、49.25%);株高(114.58 cm)和产量(4 675 kg/hm2)较CK分别提高15.57%和168%;多糖、总黄酮及总皂苷含量较CK分别提升16.30%、32.46%和15.11%。此外,拌根剂提高了土壤pH和碱解氮含量,但导致土壤有机质含量下降。

Abstract: To screen high-efficiency root dressing agent formulations and investigate their effects on the growth, quality, and soil physicochemical properties of Polygonatum kingianum Collett & Hemsl., two-year-old seedlings of Polygonatum kingianum were used as experimental materials. Nine fungicides were combined into four root dressing treatments (A1 to A4) and a control (CK). The results showed that, compared with CK, the root dressing treatments significantly improved the emergence rate, seedling survival rate, and disease resistance of Polygonatum kingianum. Among them, treatment A1 (80% tetramycin + 5% thiram + 15% captan) performed the best, with emergence and seedling survival rates of 95.75% and 95.25%, respectively. The incidence of root rot in August and September (1.25%, 4.75%) was significantly lower than that of CK (34.00%, 49.25%). Plant height (114.58 cm) and yield (4 675 kg/hm2) increased by 15.57% and 168%, respectively, compared to CK. The contents of polysaccharides, total flavonoids, and total saponins increased by 16.30%, 32.46%, and 15.11%, respectively, compared to CK. Additionally, the root dressing agent increased soil pH and alkaline hydrolyzable nitrogen content but led to a decrease in soil organic matter content.
