为摸清沂蒙山区石质褐土经济林树盘覆盖处理对水土保持效果和土壤理化性状的影响,进行了石榴园树盘土壤覆草、盖膜和松土试验。结果表明,所有处理的蓄水增温保肥效果及对土壤理化性状影响均好于对照。综合各种效应不同处理优劣顺序为:A覆草>B盖膜>C深松土>D浅中耕>E(对照)。
In order to find out the effect of tree-plate covering treatment on water and soil conservation and soil physical and chemical properties in Yimeng mountainous area, soil-covering, cover-film and soil-loosening tests were conducted on the soil of pomegranate tree.
