不同灌溉模式对枣棉间套作微生态区域温湿度的影响

目的]研究不同灌溉模式对枣棉间套作体系下生态区域的温度和湿度的变化,以期确定不同灌溉模式的生态影响效果,为优化枣棉体系灌溉模式提供理论依据.方法]通过在处理1(红枣单作)、处理2(枣棉一行双管)、处理3(枣棉微喷)、处理4(沟灌)和处理5(对照)棉花单作中分别设置不同点的3个EL - USB自动温湿度计,连续3d监测距红枣树不同距离点的微生态区域温湿度的影响变化.结果]东西走向的红枣树对微生态区域温度影响是树南＞树北＞树行间,对湿度影响是树行间＞树北＞树南；不同灌溉模式对微生态区域温度影响是处理5＞处理1＞处理4＞处理2＞处理3,对湿度影响是处理2＞处理3＞处理4＞处理1＞处理5.结论]枣树对树南树北的温湿度有影响,温度表现为树南＞树北＞树行,湿度与温度成负线性关系；枣棉间套作复合种植模式比单作模式田间的温度低,而湿度高,其中以枣棉间套作中红枣采用微喷和一行双管灌溉模式对微生态区域温度降低和湿度增加的影响较大,这种影响有利于提高红枣坐果率.

Influence of Different Irrigation Models on Temperature and Humidity of Jujube-cotton Intercropping in Micro-ecological Areas

【Objective】 The purpose of this project is to study the effects of different irrigation models of jujube-cotton intercropping in ecological areas on the temperature and humidity and determine the ecological result of different irrigation models to the environment in order to provide some scientific basis for optimum water-saving irrigation model for jujube-cotton intercropping.【Method】Three EL-USB automatic measuring system of temperature and humidity was established in the different positions in treatment 1-jujube garden,treatment 2-double water pipes in one line,treatment 3-spray,treatment 4-ditch irrigation,treatment 5-cotton,EL-USB automatic measuring system of temperature and humidity of different distances from tree row to be monitored for 3 days in a row.【Result】Effects of east-to-west jujube row on micro-ecological areas temperature are: the south of Jujube>the north of Jujube>Jujube row,and humidity: jujube row>The north of Jujube>The south of jujube;There was a negative linear correlation between humidity and temperature.Effects of different irrigation models on micro-ecological areas temperature of Jujube-cotton intercropping are: treatment 5>treatment 1>treatment 4>treatment 3>treatment 2,and humidity: treatment 2>treatment 3>treatment 4>treatment 1>treatment 5.【Conclusion】Results showed that the crown shading of a east-to-west jujube row affected micro-ecological area temperature and humidity differently with different directions from tree row.Generally,temperature is the south of Jujube>the north of jujube>jujube row.There was a negative linear correlation between humidity and temperature.The temperature of jujube-cotton intercropping is lower than that of the single cotton model,but the humidity is higher.The treatment of spray and the treatment of double water pipes influence temperature and humidity greatly,which was advantageous to increase the jujube fruit setting rate.
