摘要
通过对果粮间作系统与麦田小气候要素的对比观测。分析得出，气温与土温均低于单作麦田，湍流交换系数低于单作麦田，土壤导温率存在明显差异。果粮间作田在热力与动力方面小气候效应明显。为我区中西部地区果粮间作模式的推广提供参考。
According to the contrast observations of microclimate factors between the intercropping system of fruit tree-wheat and wheat monoculture field, temperatures of the atmosphere and soil in the former were lower than those in the latter, the turbulent exchange coefficient in former was smaller than that in the latter and there was obvious difference between their confficients of soil temperature conductivity. The intercropping fields of the fruit tree and wheat have obvious microclimate effects. The results offer an referencial model to extend the application of the fruit tree-crop intercropping in the middle and Western parts of Inner Mongolian Autonomous Region.
