摘要
条墩桑是一种优良的农林间作灌木,桑叶用来养蚕,桑条用来编织,其庞大的根系对于固沙起着重要作用。通过人工和自动气象仪器对条墩桑与花生的间作田及对照田的小气候因子(光照、风速、地温、气温、花生层温)进行观测,结果表明:间作田内的风速明显低于对照田,桑行间距8 m和13 m的间作田,风速差异不明显;间作田内光照强度减弱不明显;间作田内的平均气温、平均地面温度以及作物层温度均低于对照田,并且相对稳定;间作田内的增湿效应较为明显。
Cluster mulberry is an excellent agro-forestry intercropping shrub. Its leaves were used for rearing and shoots were used for knitting. Its large root system plays an important role in sand-fixing. The microclimate factors including wind speed, light intensity,surface temperature and temperature of air and peanut layer in the intercropping field and control plot were observed compared. The cluster mulberry and peanuts were planted in the intercroped field, but only peanuts were planted in the control plot. The results indicated that wind speed was obviously slower in the intercropping field than in the control plot. The discrepancy of wind speed was not distinct between the intercropping field and the control when the distances of cluster mulberry were 8 m and 13 m. The differences of light intensity between intercropping field and control plot were not distinct. The temperature of air, soil surface and crop layer in the intercropping field was lower than that in the control plot and relatively steady. The relative humidity in the intercropping fields was higher than that in the control plot.
