采取分次刈割的方法,对煤矿区废弃物中接种丛枝菌根真菌对紫花苜蓿的生长状况、营养吸收进行动态监测。结果表明,在煤矿区废弃物中,接种摩西球囊霉菌根真菌苜蓿的侵染率大于接种地球囊霉菌根真菌的侵染率。丛枝菌根真菌对宿主矿质营养吸收尤其是磷吸收有一定促进作用,接种菌根使植物从基质中吸收氮、磷的强度比对照高,在第6个月时磷含量达到高峰,而对照在第9个月时才达到高峰。
Taking the methods of grazing by cutting, the growth status and nutrient absorption of alfalfa inoculated arbuscular mycorrhizal fungi in coal mine waste were dynamically monitored. The results showed that the inoculation rates of mycorrhizal fungus alfalfa inoculated with Moccasin were higher than that of inoculation with mycorrhizal fungi in the coal mine waste. Arbuscular mycorrhizal fungi can promote the absorption of mineral nutrient, especially the absorption of phosphorus. The inoculation mycorrhizal fungi absorbed nitrogen from the matrix, and the phosphorus intensity was higher than that of the control. The phosphorus content peaked at the 6th month, while the control It reached its peak on the 9th month.
