摘要：In order to improve the soil nutrients of replanted soil in homestead, find the best soil improvement model. The plot experiment was used to study the effects of six amendments addition modes on soil nutrients in the root zone of replanted soil in homestead. The results show: Result 1 organic fertilizer (T2) treatment on organic matter The improvement effect is the best, the average increase is 9.37~15.49 g kg−1, followed by fly ash+organic fertilizer (T5); Result 2 the improvement agent + organic fertilizer (T4) had the best effect on the available phosphorus in the tillage layer, which was 11.95~19.18 mg kg−1 compared with the no fertilization measures; Result 3 fly ash + organic fertilizer (T5) treatment had the best overall effect on the improvement of available potassium and total nitrogen in the tillage layer, compared with the no fertilization measures increase of 31.6~34.8 mg kg−1 and 0.05~0.25 g kg−1. Organic fertilizer and fly ash can be used as the most suitable improvement model for the replanted soil of homestead in residential land in mountainous and hilly areas, it is of great significance to improve the quality of soil for homestead reclamation.
