滦南县位于河北省东部,总土地面积11.7万km2,属暖温带半湿润季风性气候,年平均气温10.6℃,常年降水量658 mm。由于地处冲击平原区,县内气候、地貌、水文等影响元素大体一致,所以种植业区划受土壤影响较大,土壤分类与养分调查对种植业区划乃至农业增产尤为重要。滦南县农牧局土肥
Luannan County is located in the eastern part of Hebei Province, with a total land area of 117,000 km2. It belongs to the warm temperate semi-humid monsoon climate with annual average temperature of 10.6 ℃ and annual precipitation of 658 mm. Due to its location in the impact plain area, the climate, geomorphology and hydrology in the county are generally similar, so the planting area is greatly affected by the soil. Soil classification and nutrient survey are particularly important for the zoning and even the agricultural increase. Luannan County Department of Agriculture and Animal Husbandry Fertilizer
