Micro-sprinkler irrigation has been a promising method to promote Panax notoginseng (Burk) F. H. Chen production but their scientific frequency in improving yield and water use efficiency of P. remains contradictory inconclusive. The objective this study was therefore examine propose management cultivation considering impact on soil water, available nutrients, root growth, yield, (WUE). micro-sprinkler experiment under shading rain-shelter conditions carried out the growing season from 2017 2018.The treatments included four frequencies, such as IF1 (irrigation once every three days), IF2 five IF3 seven IF4 nine days) 2017-2018. results indicated that treatment significantly increased nitrogen accumulation (271.98 mg plant-1). In addition, enhanced phosphorus (27.82 plant-1), potassium (408.38 total surface area (67.49 cm2 volume (3.79 cm3 plant-1) (702 kg ha-1). WUE by 29.2%, 28.1%, 37.7% compared with IF1, IF3, treatments, respectively. Our findings suggested content, reduced nutrient notoginseng, promoted growth improved quality providing theoretical basis for reasonable control green shade rain shelter cultivation.
