| 摘要: |
| 为揭示果麦间作系统内小气候因子的变化规律,利用KS4000手持气象站和SUNSCAN冠层分析系统,对环塔里木盆地枣麦、杏麦和核麦间作系统中小气候因子进行观测。结果表明:不同果麦间作系统对小麦冠层光合有效辐射量和散射辐射量均有一定的减弱作用。果麦间作系统小麦冠层风速、空气温度和土壤温度均明显降低,相对湿度明显增大,在枣麦、杏麦和核麦间作系统中具有相同的趋势。可见果麦间作栽培模式是一项改善田间小气候,有效防治环塔里木盆地一带常出现的干热风、浮尘和强对流等灾害性天气对农作物造成危害的重要措施,为当地农业生产提供了重要生态保障。 |

| Abstract: |
| In order to understand the changing rule of microclimate factors in fruit tree-wheat intercropping system in Tarim basin,Xinjiang,we studied the microclimate of jujube-wheat,apricot-wheat and walnut-wheat intercrops systems.The microclimate factors were measured in jujube-wheat,apricot-wheat and walnut-wheat intercropping systems by using KS4000 handheld meteorological observation station and SUNSCAN canopy analysis system.The results showed that all the microclimate factors,such as the average wind speed,air temperature,soil temperature,photosynthetically active radiation(PAR) and diffuse radiation are obviously decreased,relative humidity is increased sharply in wheat canopy compared to monocultural field.Similar trend was also discovered in jujube-wheat,apricot-wheat and walnut-wheat intercropping systems.The fruit tree-wheat intercropping cultivation mode could improve the field microclimate,and prevent the dry-hot wind,dust and strong convective severe weather damage to crops,which regularly occurs in Tarim basin,and thus could also provide an important ecological protection for agricultural production. |
