A pot experiment was conducted to investigate the efficacy of a post-fire land management practice, including plant cultivation (Lolium perenne) combined with poultry manure addition, for restoring the protective vegetation cover in soils degraded by high intensity wildfires. The greenhouse experiment was performed with three burnt pine forest soils with added poultry manure at two doses of application and comparing the data with those obtained using NPK fertilizer. A significant effect of the amendment, soil properties and the interaction between amendment and soil properties on vegetation cover (phytomass production, nutrient content) was detected, but often the amendment treatment explained most of the variance. Changes induced by the organic amendment were more marked than those induced by inorganic fertilization. The increase of phytomass and nutrient uptake with poultry manure addition indicated the beneficial effects of this soil management practice. These findings can serve to develop field experiments and burnt soils reclamation technology.
进行了一项盆栽试验，以研究一种火灾后土地管理措施的效果，该措施包括植物种植（多年生黑麦草）并添加家禽粪便，用于恢复因高强度野火而退化的土壤中的保护性植被覆盖。温室试验使用了三种火烧后的松林土壤，以两种施用量添加家禽粪便，并将数据与使用氮磷钾肥料获得的数据进行比较。检测到改良剂、土壤性质以及改良剂与土壤性质之间的相互作用对植被覆盖（植物生物量生产、养分含量）有显著影响，但通常改良剂处理解释了大部分方差。有机改良剂引起的变化比无机施肥引起的变化更为明显。添加家禽粪便后植物生物量和养分吸收的增加表明了这种土壤管理措施的有益效果。这些发现可用于开展田间试验和火烧土壤复垦技术。
