| 摘 要： | 研究了不同集雨保墒措施对山地苹果园土壤水分、温度和叶片生理的影响。结果表明,与对照处理、单纯塑膜微集水处理、秸秆覆盖处理相比,干旱季节和秋雨季节塑膜微集水促渗处理0～60cm土层土壤含水率分别提高15.50%、7.65%、9.78%和38.66%、30.87%、21.69%,60～200cm土层土壤贮水量分别提高14.75%、5.68%、10.46%和17.03%、5.14%、10.19%。0～25cm土层,塑膜微集水促渗处理的年平均土壤温度为22.7℃,比对照处理提高0.6℃。塑膜微集水促渗技术能提高山地苹果树的叶片相对含水率、光合速率、蒸腾速率和水分利用效率。 |

Effects of Micro-Catchment and Promote-Infiltration on Soil Moisture, Temperature and Leaf Physiological Indices of Mountain Apple Orchard |
|
| Abstract: | The effects of different catchment and soil moisture conserving ways on soil moisture,temperature and leaf physiological characteristics were studied.The result indicated that the plastic micro-catchment and promote-infiltration could increase soil moisture content and improve water environment of orchards significantly.The soil water content in 0～60cm layer under the plastic micro-catchment and promote-infiltration increased by 15.5%,7.65%,9.78% and 38.66%,30.87%,21.69%respectively in the dry season and in the rainy season over those under three modes(CK,ridge film mulching,straw mulching).In 60～200cm soil layer,the soil water storage under the plastic micro-catchment and promote-infiltration increased by 14.75%,5.68%,10.46% and 17.03%,5.14%,10.19% in the dry season and in the rainy season respectively.The mean annual temperature under the plastic micro-catchment and promote-infiltration in 0～25cm soil layer was 22.7℃,which was 0.6℃ higher than CK.The plastic microcatchment and promote-infiltration could improve the leaf relative water content,net photosynthetic rates,transpiration rate and the water use efficiency. |
