农林复合系统中农田蒸散及作物水分利用效率的研究

Study on the Farmland Evapotranspiration and the Water Use Efficincy of Crop of the Compound System of Agroforestry

本文对黄淮海平原不同地学条件下两个农林复合系统试验区(简称系统)的土壤水分平衡特征进行了分析,讨论了<系统>内农田蒸散的若干规律及对作物水分利用效率的影响。

This article analysed the characteristics of the water balance in these two ex- perimental districts of the compound systems of agroforestry under the different geoscience condition in Huang-Huai-Hai Area,discussed some laws of the farmland evapotranspiration under the protection of these systems and studied the influence of these systems to the water use efficiency of crops.
