摘　　要： 在田间试验条件下,研究了滴灌施肥与传统灌溉施肥对马铃薯生长及产量和品质的影响。试验设3个处理:常规灌溉施肥处理A,滴灌施肥处理B(马铃薯浅植+培土),滴灌施肥处理C(马铃薯深植+不培土)。结果表明:滴灌施肥处理能显著提高马铃薯植株的生物量;滴灌施肥处理在节约10%的生产成本的同时,显著增加马铃薯块茎产量,增幅达37.31%～47.39%,经济效益显著提高。研究结果对滴灌施肥技术在马铃薯生产上的推广应用具有重要意义。 Drip-fertigation and traditional irrigation and fertilization were compared for the effects on potato production and quality under field conditions. Three treatments were set up, i.e. traditional irrigation and fertilization, drip-fertigation with shallow planting and hilling up later, and drip-fertigation with deep planting but without hilling up, in this research. Drip-fertigation significantly increased biomass of potato, and also saved the production cost by 10% and increased potato tuber yield by 37.31%-47.39%, thereby significantly increasing the economic benefit. These results lay a sound foundation for extension of the drip-fertigation technique in potato production.
