Abstract: In order to reduce the risk of maize drought and yield reduction in the western semi-arid region of Heilongjiang Province.Jinqing 707 was used as material to study the effects of different tillage patterns on maize water utilization and yield in Longjiang County,so as to explore the law of water utilization in maize seedling stage.The results showed that the effect of no-tillage watering on soil moisture content of 0-30 cm was significant.The water use efficiency of no-tillage watering was 3.97% higher than that of conventional planting.Moreover,the economic benefit of no-tillage watering was 2 076.68 yuan per hectare higher than that of conventional planting.
