礼泉县各果园土壤养分的现状分析

目的]为了解礼泉县果园土壤现状.方法]采取主要的果园即苹果、葡萄、石榴、樱桃地的土壤样品,对土壤pH、速效钾、铵态氮、水分等指标进行检测.结果]石榴园的铵态氮含量最高,为（51.89±1.15） mg/kg,其次是苹果园,最低的为葡萄园;速效钾含量在（114.46～ 146.99） mg,/kg之间,苹果园的速效钾含量最高;土壤pH没有明显的差异,pH接近于7;樱桃园的水分含量最高,约10 mg/kg,其余果园的水分含量较低.结论]不同的果园土壤养分差异较大,不同的果树对土壤养分的影响差异明显.

Analysis on Orhard Soil Nutrients Stutus in Liquan

Objective] The research aimed to understand present situation of Liquan orchard soil.Method] The main orchard soils,namely,apples,grapes,pomegranates and cherry were adopted.The soil pH,available potassium,ammonium nitrogen,and water content were tested.Result] Ammonium nitrogen content in pomegranate orchard was the highest,reaching （51.89 ± 1.15） mg/kg,followed by apple orchards,the lowest was the vineyards.Conclusion] Available K content was between 114.46 and 146.99 mg/kg,and that in apple orchard was the highest.The soil pH had no obvious difference,and pH was close to 7.The maximum moisture in the cherry orchard was about 10 mg/kg,and the others were low.Conclusion] There were differences in soil nutrient of different orchards.The influence of different fruit trees on the soil nutrient difference was obvious.
