摘要

通过比较种植在相临地块上而定植年限不同的仁用杏人工林地土壤理化性质，分析了不同定植年限仁用杏人工林地土壤水分和养分的变化规律。研究结果表明。仁用杏定植时间越长，对土壤理化性质影响越大。定植2年仁用杏的耗水量与同期降水量基本相同，而随着定植年限的延长，仁用杏的耗水量逐渐增大，定植6年仁用杏的耗水量就已经超过了同期降水量，土壤有效水贮量减少，土壤水分处于逐渐耗竭的状态；同时，随着仁用杏种植年限的延长，仁用杏人工林地的土壤有机质、硝态氮、有效磷、速效钾等含量降低，土壤肥力迅速下降，硝态氮、有效磷和速效钾都成为了仁用杏生长发育的限制因素。

Abstract

Through comparing the physico-chemical property of soil in artificial timber land with almond-aprieot of different planting age which was planted on the near plot of land

the varying law of soil water and nutrients was analyzed. Results indicated that the longer age of almond-apricot was

the larger the effects of the physicochemical property of soil were. Water consumption of almond-apricot of two was basic equal to the precipitation in the same stage. Water consumption of almond-apricot was gradualy increased by an increase in the age of almond-apricot. Water consumption of almond-apricot of six already exceeded the precipitation of the same stage

available moisture storage in soil body decreased and soil moisture were gradualy exhausted. Moreover

the concentrations of soil organic matter

nitrate nitrogen

available phosphorus and readily available potassium in artificial timber land with almond-apricot decreased with the age of almond-apricot increasing

soil fertility rapidly fell down. Nitrate nitrogen

available phosphorus and readily available potassium are limiting factors of the growth and development of almond-apricot.
