Soil evaporation variation and estimating model from winter wheat field in intercropping patterns

Soil evaporation among winter wheat plants was measured by Micro-lysimeter under the sole cropping and intercropping patterns. The authors analyzed variation law of soil evaporation, and discussed the main factors which produce an effect on soil evaporation from the winter wheat field, and through it, the authors established estimating model of soil evaporation under the sole cropped and intercropping winter wheat by multivariate regression analysis. Estimated values were fitted to observed data.
