Abstract: In order to make sure the planting technology of resisting drought and saving water of soybean in dry farming areas, insure the sustainable development of soybean production, we investigated the technology of resisting drought and saving water on soybean through the character of Heilongjiang Province as dry farming areas. The result showed: covering film between rows increased the soil moisture. It increased 1.19% comparing with the no covering treatment; (2) spraying no-tillage regulator improved the physical character of soil obviously, bulk density was lower than the period before sowing; (3) covering film and applying fertilizer rationally improved the indexes of soybean photosynthesis at a certain extent, its yield and water use efficiency were higher than other treatments.
