| 摘 要： | 目的]探索枣园间作生物学基础与小气候效应。方法]2009～2011年，在枣园内间作小麦、花生、大豆、大蒜、西瓜、蔬菜等，对照为单一作物种植地，采取固定观测和同步移动观测相结合测量空气温度、地表温度、空气相对湿度、风速等田间小气候因子。结果]枣树与间作作物之间在光照、肥水方面存在资源利用型竞争关系，但与多种作物在物候期上存在差异，枣树与间作作物在需水、需肥及光照的关键时期也有交错。同时，枣园间作与对照比农田小气候环境变化显著（ P＜0.05）：枣园间作地比对照空气温度降低幅度为0.2～0.7℃、地表温度降低幅度为2.1～2.5℃、空气相对湿度提高幅度为3.7%～6.8%、风速减低幅度为0.2～0.4 m/s。结论]该研究表明枣园间作可在中原地区，乃至中国北方地区大力推广。

| Abstract: | Objective] This study aimed to explore the biological basis and microcli-mate effects in intercropping jujube orchard. Method] From 2009 to 2011, jujube was intercroped with wheat, peanut, soybean, garlic, watermelon, vegetables etc. By fixed observation and simultaneous mobile observation, the field microclimate factors such as the air temperature, surface temperature, air relative humidity, wind speed, etc. were measured, with mono-crop farmland as the control. Result] The competi-tion relationship existed between jujube trees and the intercropped plants for re-sources such as il umination, fertilizer, and water; however there were differences in phenological phases and the critical periods in needing for water, fertilizer and il u-mination between jujube and intercropped plants. Meanwhile, there was significant difference （P〈0.05） in the variation of agricultural microclimate environment in jujube field compared with that in control farmland. Compared with the control, the air tem-perature in intercropping jujube orchard was reduced by 0.2 to 0.7 ℃, the earth surface temperature reduction ranged from 2.1 to 2.5 ℃, the relative air humidity increased by 3.7% to 6.8% and the wind speed decreased by 0.2 to 0.4 m/s. Conclusion] Al above results showed that intercropping in jujube orchard could be promoted in central China and northern China areas. |
