The purpose is to reveal the spatial variability law of soil nutrients in Luonan County, and provide technical support for scientific fertilization in Forsythia suspensa planting and precision agriculture. We used geographic information technology and geostatistical principles, and based on the information collection of soil samples, analyzed the main nutrients’ status in soil and the spatial variation trend of main nutrients’ indicators. The results showed that soil pH value in Forsythia suspensa planting area was mostly neutral, organic matter was deficient as a whole, especially in the southeast region. Nitrogen decreased from north to south, and it was deficient in southeast region. Available phosphorus content was at a suitable level, decreased from west to east and increased from south to north. Available potassium content was higher, increased from west to east and from south to north. As to the available content of microelements, iron was rich, and manganese, copper and zinc were at suitable level, while boron was deficient. The results can be used for the rational fertilization on Forsythia suspense and its planting layout.
Key words: Forsythia suspense; planting; soil nutrient; spatial distribution; Luonan County
