Soil nutritional status of Lijian Scientific Research Base of Guangxi Academy of Agricultural Sciences
摘要
Abstract
[Objective]In order to appropriately utilize the land resources at Lijian Scientific Research Base of GXAAS in Wuming (Nanning) and for scientific (soil test based) fertilization, the nutritional status of soils was investigated. [Method]By using GPS location, samples of different types of soils were taken from 0-20 cm soil layer and the nutrient contents were analyzed. [Result]The soils of Lijian Scientific Research Base showed pH in the range of 5.04-7.00 and 14.98 g/kg average organic matter content. The average total N,P and K contents in soils were 0.86, 0.50 and 4.19 g/kg, respectively. The average available N, P, K, Ca and Mg contents in soils were recorded as 67.7, 12.0, 90.2, 1022.0 and 66.6 mg/kg, respectively. Amongst micronutrients, the average available Cu, Zn, Fe, Mn and B content weres found to be 0.57, 0.63, 27.7, 24.7 and 0.20 mg/kg, respectively. [Conclusion]The soils at Lijian Base contained lower organic matter, N, P and K, and was deficient in Zn and extremely deficient in Mg and B. However, Ca, Cu, Fe and Mn contents were sufficient for sustaining growth and development of plants.关键词
