【摘要】 通过用不同材料对山地果园中的桃树进行根盘覆盖 ,并对其气象效应及与桃子产量品质的关系进行研究 ,结果表明 :(1)各处理与对照相比 ,桃树内膛的总辐照均有所提高 ,其中以银膜覆盖增幅最大 ,其增加率约为 2 4 % ;(2 )覆盖改善了土壤的物理特性 ,即使土壤的湿度和孔隙度比对照有所加大 ;(3)与对照相比 ,覆盖使果子的产量品质有所提高 ,其中以银膜覆盖最为显著 ;(4 )各种覆盖措施 ,以银膜的气象效应最为显著 ,以覆草最为经济实用。更多还原

【Abstract】 The meteorological effects of covering ground around tree trunks with different materials in peach orchard and their relations to the peach outputs and qualities were studied. The results show that in orchard where the grounds are covered with different materials, the total radiation inside the tree crowns obviouily increased, especially the ground where is covered with silver film, the radiation increased by 24%, which is the greatest; The physical characters of the soils are improved, the soil moisture and porosities greatly increased; The fruit outputs and quanlities are improved, especially on the ground where is covered with the silver film; Among the different materials, the silver films’ meteorological effects are most obviously and the wheat straws are most economically and practically.更多还原
