Furrow irrigation, ridge irrigation, drip irrigation, micro-sprinkler irrigation and non-irrigation(CK) were performed to investigate the influences of different irrigation methods on soil moisture, photosynthesis, yield and fruit quality in pear orchard, to selecte the appropriate water-saving irrigation technology. The results showed that: (1) Micro-sprinkler irrigation led the highest soil moisture content in 0 ~ 60 cm soil layers, followed by drip irrigation, ridge irriga-tion, furrow irrigation and CK, micro-sprinkler irrigation's water storage capacity was significantly higher than other irri-gation methods; (2) The order of net photosynthetic rate performance was micro-sprinkler irrigation≥ drip irrigation≥ ridge irrigation > furrow irrigation > CK, which showed that micro-sprinkler irrigation treatment of pear leaf photosynthetic capacity was the strongest, followed by drip irrigation; (3) The yield of micro-irrigation was the best, followed by drip irrigation, compared with controls, yield per plant rised by 54.98% and 44.18%; (4) Besides, micro-sprinkler irriga-tion and drip irrigation could also raise the fruit quality, such as bigger fruit size, higher content of soluble solids and to-tal soluble sugars, lower fruit firmness, lower content of acid and stone cell. It is concluded that, micro-sprinkler irriga-tion can improve the soil moisture condition and increase the ability of photosynthesis and result in higher yield and fruit quality more significantly than others, which is an ideal water-saving irrigation technology.%采用沟灌、畦灌、滴灌、微喷灌和不灌水(CK)5种灌溉方式,通过对比试验研究不同灌溉方式对梨园土壤水分含量、叶片光合参数及果实产量与品质的影响,筛选适宜的节水抗旱灌溉技术.结果表明:(1)果树根层(0-60 cm)土壤含水量表现为微喷灌＞滴灌＞畦灌＞沟灌＞CK,微喷灌的蓄水能力显著高于其它灌溉方式；(2)叶片净光合速率表现为微喷灌≥滴灌≥畦灌＞沟灌＞ CK,微喷灌处理的梨树叶片光合作用能力最强,其次是滴灌；(3)增产效果最好的是微喷灌,其次是滴灌,单株产量分别比CK提高了54.98％和44.18％；(4)在果实品质方面,微喷灌和滴灌显著提高了果实的单果质量、可溶性固形物含量及可溶性总糖含量,并且显著降低了果实硬度、含酸量及石细胞含量,两者对果实品质的改善效果明显好于沟灌和畦灌.综合分析表明,微喷灌能够明显改善梨园土壤水分条件和梨树光合能力,显著提高果实产量与品质,是较为理想的节水灌溉技术.
