摘 要：
以郑州壤质黏土为供试土壤,紫茄为供试作物,设置常规地下滴灌(CK)为对照,研究以循环曝气为增氧方式的增氧地下滴灌(ASDI)对温室紫茄生长及土壤通气状况的影响.结果表明,与CK相比,ASDI处理下15 cm土层E_h最大提高47.92%,D_O最大提高26.95%,而开花期R_s最大提高39.24%,紫茄根长增加23.89%,根系活力提高28.61%,净光合速率、蒸腾速率、气孔导度分别提高11.76%,8.02%,16.67%,叶绿素含量增加7.34%,株高增加22.04%,产量增加25.71%,水分利用效率提高25.82%,作物氮、磷、钾利用效率分别提高55.56%,42.86%,43.75%,且存在显著性差异(P<0.05).增氧地下滴灌显著改善了土壤通气状况,促进温室紫茄的生长状况,提高作物水分、养分利用效率,进而可实现作物增产的目的.

摘 要：
The experiment was conducted with purple eggplant as test crop and Zhengzhou loamy clay as test soil, and the normal subsurface drip irrigation was set as control group(CK) to disscuss the effects of aerated subsurface drip irrigation(ASDI) on the growth and soil aeration under greenhouse purple eggplant cropping system. The results show that compared with CK, soil E_h and D_O at 15 cm soil depth under ASDI are respectively increased by 47.92% and 26.95%, and R_s is increased by 39.24%. Root activity is increased by 28.61%, and net photosynthetic rate, transpiration rate and stomatal conductance are increased by 11.76%, 8.02% and 16.67%, respectively. Root length, plant height, yield and water using efficiency of purple eggplant are increased by 23.89%, 22.04%, 25.71% and 25.82%, respectively. Crop nitrogen, phosphorus and potassium in ASDI are respectively increased by 55.56%, 42.86% and 43.75%, while there is significant difference in the above differences(P<0.05). The aerated subsurface drip irrigation can significantly improve soil aeration and promote crop growth with increased crop biomass, yield and crop water and fertilizer use efficiency to enhance crop yield.
