Evaluation of Soil Nutrient in Original Habitat of Garcinia xipshuanbannaensis
摘要
Abstract
In order to promote the subsequent relocation protection and field return of Garcinia xipshuanbannaensis,based on the survival status of G.xipshuanbannaensi,the soil collection was carried out in its original habitat.A total of 20 soil samples were collected and eight indicators,namely,organic matter(OM),total nitrogen(TN),total phosphorus(TP),total potassium(TK),available nitrogen(AN),available phosphorus(AP),available potassium(AK),and pH,were measured,and the results of the measurements were evaluated by using the three methods of Cloud modeling,ANOVA analysis,and multiple comparisons among populations.Based on the evaluation results,it is known that the survival soil of G.xipshuanbannaensis was low in nutrient content,rich in OM,TN as well as AK,with a very low content of AP,and the soil was strongly acidic.ANOVA analysis revealed that TN,TP,TK and AN were significantly different among populations,while OM,AP,AK and pH were not significantly different among populations.Multiple comparisons among populations for TN,TP,TK,and AN factors revealed that P5 was significantly higher than P3,highly significantly higher than P1 and P2,and the difference with P4 was not significant,and the difference among P1,P2,P3,and P4 was not significant.P4 was highly significantly higher than P1,P2,and P3,and significantly higher than P5,and the difference among P1,P2,P3,and P5 was not significant on the TP index.On the TK index,P1 was significantly lower than P4,P5 was significantly higher than P1 and P2,and the rest of the differences between populations were not significant.P5 was extremely significant higher than the other populations,and the rest of the populations did not differ significantly from each other on the AN index.P5 is basically significantly different from all other populations,and the survival of P5 should be emphasized in subsequent studies,while the intensity of P4's disturbance by agricultural activities also needs to be tested.关键词
