Abstract:
A series of serious consequences had been caused by unreasonable fertilization in Ningxia wolfberry production,including decline of wolfberry production,soil hardening,enrichment of nitrogen and phosphorus,tree leaves premature senility and so on.Combined with GPS,soil samples were collected by the ‘S’ shaped multi-point and mixed form.Based on geostatistics and ArcGIS,distribution of soil fertility level of wolfberry with different planting ages in Huinong district and Zhongning county of Ningxia was studied.The results showed that the soil total nitrogen content level of 5 years old wolfberry origin was 0.9-1.5 g?kg-1 and the soil organic matter content level was 10.0-15.0 g?kg-1.Most of the soil available K content level was < 200 mg?kg-1 or >300 mg?kg-1 and the soil available P content level was <50.0 mg?kg-1 or 80.0-120.0 mg?kg-1.The soil potassium and phosphorus supplying capacity had a big gap and much more organic fertilizer needed to be applied to improve the soil buffering ability and fertility preserving capacity.The soil total nitrogen level of 6-9 years old wolfberry origin in Huinong was <1.5 g?kg-1 and the soil organic matter level was <15.0 g?kg-1,a little lower than that of Zhongning.And also the soil total nitrogen supplying capacity and fertility preserving capacity were slightly weaker than that of Zhongning.The soil total nitrogen and organic matter level of above 10 years old wolfberry origin in Huinong were the same as in Zhongning,with the contents of 0.9-2.0 g?kg-1 and >10.0 g?kg-1 respectively.The soil ability of nitrogen supplying capacity and fertility preserving capacity were stronger.The soil available K level of 6-9 years old wolfberry origin in Huinong was <250 mg?kg-1 and the soil available P level was <50.0 mg?kg-1,slightly lower than that of Zhongning.The soil available K level of above 10 years old wolfberry origin in Huinong was >200 mg?kg-1 and the soil available P level was <80.0 mg?kg-1,lower than that of Zhongning.The soil potassium and phosphorus supplying capacity of above 6 years old origin in Huinong was weaker than that of Zhongning.The soil phosphorus supplying capacity of above 10 years old wolfberry origin in Zhongning was the strongest and its′ requirement of phosphate fertilizer was the fewest.In this study,theoretical basis and data support were provided for the reasonable fertilization of wolfberry with different planting ages in Huinong district and Zhongning county of Ningxia.
