摘要： 为获得一种有利于石灰岩矿岩质坡面覆土平台区葛\[Pueraria lobata (Willd.) Ohwi\]快速生长的土壤基质改良措施，以无为杨家岭石灰岩矿东采区第三阶平台区已实施表层覆土的岩质坡面作为试验区，评价不同施肥措施对葛在重构土壤上的生长状况。试验小区设置：A(100%复合肥)、B(75%复合肥+25%有机肥)、C(50%复合肥+50%有机肥)、D(25%复合肥+75%有机肥)、E(100%有机肥)、CK(对照，不施肥)。2022年8月，对葛的生理生化指标进行分析，并用熵权法对葛的生长状况进行综合评价。结果表明：与CK相比，施肥措施均增加了葛的株长及其叶片的干重，提高了含水率、叶绿素含量、氮磷钾含量、可溶性蛋白质含量以及3种抗氧化酶（POD、CAT、SOD）活性，同时均降低了叶片的MDA含量。综合评价结果表明，25%复合肥+75%有机肥的处理最利于葛的生长，可用于该岩质坡面植被重建的生产实践。

Abstract: In order to obtain a soil matrix improvement measure which is beneficial to the rapid growth of Pueraria lobata in the soil covered platform area of the limestone mine, the rock slope which has been covered with topsoil in the third stage platform area of the east mining area of Yangjialing limestone mine in Wuwei，Anhui, China, was taken as the test area to evaluate the growth of P. lobata on the reconstructed soil under different fertilization measures. Experimental plot settings: A(100% compound fertilizer), B(75% compound fertilizer +25% organic fertilizer), C(50% compound fertilizer +50% organic fertilizer), D(25% compound fertilizer +75% organic fertilizer), E(100% organic fertilizer), CK (control, no fertilizer). In August 2022, physiological and biochemical indexes of P. lobata were analyzed, and the growth status of P. lobata was comprehensively evaluated by entropy weight method. The results showed that compared with CK, fertilization groups increased plant length and leaf dry weight, water content, chlorophyll content, nitrogen, phosphorus and potassium content, soluble protein content and activities of three antioxidant enzymes (POD, CAT and SOD), while decreased MDA content in leaves. The comprehensive evaluation results showed that 25% compound fertilizer +75% organic fertilizer treatment was the most beneficial to the growth of P. lobata, which could be used for the production practice of vegetation reconstruction on the rocky slope.

Key words: fertilization measures, vegetation reconstruction, rocky slope, Pueraria lobata, comprehensive evaluation
