摘　　要：膜下滴灌是一种新型的节水灌溉技术,由于其显著的节水、节肥和增温效应,近年来在水稻生产中开始应用。本研究以"空育131"材料,采用随机试验设计,研明镁肥对寒地膜下滴灌旱种水稻产量的影响,为寒地水稻膜下滴灌旱作高产栽培技术提供理论依据和技术支撑。主要研究结果如下:镁肥的施用增加了膜下滴灌旱种水稻的穗长和单穗重。施用镁肥,膜下滴灌旱种水稻的穗数/m2和结实率分别增加了3.95%和11.98%、穗粒数和千粒重分别降低了0.47%和2.10%。镁肥的施用增加了膜下滴灌旱种水稻的产量。Drip irrigation under plastic film mulching is a new water-saving irrigation technology. It has been used in rice production in recent years because of its effects of water-saving,fertilizer-saving and temperature-increasing. With Kongyu131 as material,the effect of magnesium fertilizer on yield of upland rice under drip irrigation with plastic film mulching in cold region is studied with randomized design.The object is to provide theoretical basis and technical support for high-yield culture technique of upland rice under drip irrigation with plastic film mulching in cold region. The main results are as follows： under the application of magnesium fertilizer,the panicle length and panicle weight of upland rice is increased; the panicles per square meter and kernel setting rate of upland rice is increased by 3.95% and 11.98%,respectively; the grain number per panicle and 1 000-grain weight of upland rice is decreased by 0.47% and 2.10%,respectively; the yield of upland rice is increased.
