摘要
农林间作可以减少土壤水分径流量89.7～219.5mm,占年降水量的9.1%～22.2%,增加土壤入渗量64.2～225.1mm,占年降水量的65.5%～22.7%。在林间农地上,土壤水分状况得到了改善,有利于滇中高原区旱季的小春生产。
Forest-farm intercroping can decrease 89.7-219.5 mm runoff,accountingfor 9.1%-22.2% of the annual precipitation;increase 64.2-225.1mm seepagedischarge,accounting for 6.5%-22.7% of the annual precipitation.The con-dition of soil moisture has been improved on forest-farmland by the be-nefit of the protection forest.It is benefit for spring production on thedryland of Platean Red Soil in Central Yunnan.
