摘要:

揭示洛南县土壤养分空间变异规律,为指导该县连翘种植科学施肥和服务精准农业提供技术支撑。本研究采用地理信息技术和地统计学原理,在土壤样品信息采集的基础上,探讨分析该县土壤养分状况和主要养分指标空间变异趋势。研究表明:洛南连翘种植区土壤pH值多为中性;有机质整体较缺乏,尤以东南部地区缺乏明显;氮素从北到南呈减少趋势,东南部地区含量较缺乏;速效磷为适宜水平,从西向东呈减少趋势,自南向北呈增加趋势;速效钾含量较高,从西向东、自南向北呈增加趋势;微量元素有效含量中铁较丰富,锰、铜、锌处于适宜水平,硼较缺乏。研究结果可供布局连翘种植基地及连翘种植合理施肥参考。

Abstract:

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
