非充分灌溉对菌根化柑橘生理效应的影响研究

Studies on the Effect of Deficit Irrigation on the Physiology of Citrus Inoculated with AMF(Arbuscular Mycorrhizal Fungi)

通过对重庆市涪陵区柑橘果园在不同生育期实施不同灌水量试验,分析了非充分灌溉对果园土壤理化性质、柑橘生理及主要形态指标和品质产量的影响.结果表明:非充分灌溉保持了土壤的含水量,提高了柑橘的光合作用等,进而改善了果实的产量及品质,与此同时,在最大程度上节省了水资源的利用.

The effects of deficit irrigation on the physico-chemical properties ot the soil, and the physiological and morphological indexes and fruit quality and yields of citrus trees were studied through controlling the volume of irrigation during different growing periods of citrus inoculated with AMF in Fuling Orchard, Chongqing. The results demonstrated that deficit irrigation retained soil water content, enhanced the photosynthesis of citrus and, eventually, improved the quality and yields of citrus trees.
