梨树微喷灌节水试验研究

Water-saving experiments of micro-Sprinkler irriagtion for pear treas

微喷灌是目前梨园较好的节水灌溉方式，它弥补和克服了滴灌和喷灌在果园应用中的许多弊病。节水试验表明微喷灌在节水，改善土壤物理性质，枝叶、树冠、根系发育以及产量和单果重等方面都优于管畦灌和传统漫灌。

Micro-sprinkler irrigation is the way of good water-saving irrigation for pear trees gardens at present,which makes,up and overcomes disadvantages in the practice of trickle and sprinkler irrigation.The water-saving experiments indicated that micro-sprinkler irrigation is superior to pipe border and traditional flooding irrigation in the aspects of water-saving,improving soil characteristics,developing branches,crown and roots as well as output and the unit weight of fruit.
