摘    要:通过对土壤养分变化的研究,结果一明,幼林期农林养分的竞争较小,选择适宜的间作品种有利于改善土壤的养分状况,豆科作物以改善土壤速效性氮,降低磷的含量为特性;谷类作物能较全面地改善土壤的养分含量;西瓜种植因施肥,可改善土壤的有机质,速效性氮和速效性磷,但肥效持续时间较短。

关 键 词:农林间作  土壤养分  农林复合经营

Abstract:Combination of forestry and agricultural crops is an important measure to increase productive capacity of forest area. Through the study on variation of soil nutrient, it is advantageous to improve the soil nutrient to select suitable intercropping variety. Legume has characteristics of improving soil rapidly available nitrogen and decreasing the content of phosphorus. Cereal crops can all-sides improve soil nutrient content. Although planting watermelon can improve soil organic matter. rapidly available nitrogen and phosphorus. the continued time of fertilizer efficiency is short.
Keywords:Combination of forestry and agricultural crops  Soil  Nutrient
