摘　　要：红壤丘陵旱地作物采用覆盖技术．研究表明，能有效地提高土壤含水率，降低土壤水分吸力，降低土壤温度，减少土壤蒸发，保持土壤水分，提高土壤抗旱能力。使作物生长发育良好，增加作物产量。In the soil with mulching, the moisture content is increased significantly, the soil moisture suction.soil temperature and evaporation is reduced respectively, the drought resistance is improved,the growth and development of the crop is promoted, the yield is increased, in comparison with control.
