摘要
垄作区田作为水土保持措施已在黑龙江省丘陵地区推广应用。由于垄作区田能拦截流失土壤和地面径流 ,其防止水土流失的效果十分明显。由于垄作区田能形成土壤水库 ,增加土壤湿度 ,因此具有节水增水作用。本研究提出了一种新的区田设计方法 ,并编成计算机程序 。
As a soil conservation tillage method, ridged-furrow has been applied in sloping field. Owing to the ridge, the effect of soil conservation is obvious. Because the ridged-furrow can form soil reservoirs and increase soil moisture, it can save and increase water. A new design method and the computer program were developed,which could be references for tillage in semi-arid slope field.
