Abstract: Around the sustainable develepment of dryland farming, it has been testing and researching for a long period in the world. The advanced Australian conservation tillage method was introduced in 1991, and was tested in Shanxi Province experimental plots. The test showed that: the conservation tillage has the comprehensive profits of conserving water, improving soil, increasing production and income, and improving ecological envionment. But the planting quality is not so good, which held back further test. Although it can increase the adaption by improving the machine, when the stalk covering rate reaches 80%, a series of problems would appear, e.g. in winter, it is difficult to prevent wind and fire; in spring, the soil temperature goes up slowly, and it is difficult to clean the weeds growing in the crops .By the further test, shallow rotary tillage or shallow harrow of the surface soil, can solve all the problems. Stalk covering, surface soil shallow tillage, and stubble planting make up the matured technical system of conservation tillage method.
