摘　　要：对昭林杨开展灌溉与不同覆盖保墒措施试验,探讨灌溉与覆盖保墒措施对昭林杨生长的影响,为内蒙古半干旱地区林木生产经营降低生产耗水、促进林木生长提供探索。本试验采取灌溉次数与覆盖保墒措施2因素4水平试验设计。结果表明:灌溉次数、覆盖保墒措施对昭林杨的生长存在显著差异(P<0.05),灌溉次数以6次·a-1最好,覆盖保墒措施以坑内施有机肥和地膜覆盖为佳;隶属函数评价表明,适宜昭林杨最佳的节水保墒措施为灌溉5次·a-1+坑内施有机肥和灌溉5次·a-1+地膜覆盖2种复合模式,采用地膜覆盖作为保墒措施更具时效性。Based on the experiment of irrigation and different soil moisture conservation with mulching,the influences of irrigation and different soil moisture conservation with mulching on the growth of Populus×xiaozhuanica cv.‘Zhaolin’have been discussed.It is of great value for forest production and management in semi-arid area of Inner Mongolia to reduce water consumption during production and promote forest tree growth.Two factors and four levels of irrigation times and measures of soil moisture conservation with mulching are adopted in this experiment.The results show that irrigation times and measures of soil moisture conservation with mulching are the main factors which have different effects on the growth of Populus×xiaozhuanica cv.‘Zhaolin’(P<0.05).The optimal times of irrigation is 6 times per year.Applying organic fertilizer in pit and mulching with plastic film have the best effect.The membership function evaluation shows that the best water saving and soil moisture conservation measures for Populus×xiaozhuanica cv.‘Zhaolin’are two compound modes,which is irrigating five times per year+applying organic fertilizer in pit and irrigating five times per year+mulching with plastic film.The use of mulching plastic film as a measure of soil moisture conservation is with timeliness.
