摘要： It is a world-wide concerned problem to more efficiently use water resources in agricultural production, and it becomes a hot issue to adopt a more water and fertilizer-saving in grain production. Focusing the main rice producing areas in Inner Mongolia during 2018-2019, this study analyzed the growth stage and morphological characteristics (plant height and root system) of the rice through mulched drip irrigation aerobic rice plot. And the yield of aerobic rice and the factors affecting the yield, as well as evaluated the economic benefit indexes (income and cost) of mulched drip irrigation aerobic rice were discussed. The results showed that the seedling emergence rate of mulched drip irrigation aerobic rice was 4.1% lower than that of traditional transplanting rice, and the root length, average diameter, surface area and volume were lower than those of traditional rice. In addition, the rice with higher plant height and more panicle would get less grain, while more effective tillers and larger 1000-grain weight would get better yield. Compared with conventional rice cultivation, mulched drip irrigation maize and soybean, mulched drip irrigation aerobic rice has significant increase in production and efficiency.
