rategic adjustment of structure in agriculture and rural economics,
work relating agriculture, rural areas and farmers remains top priority. Especially in China's accession to
the WTO and national implementation of the western development strategy, the market-oriented
agriculture, the process of internationalization for Aksu oasis agricultural production has brought greater
opportunities and challenges.

the inheritance and
innovation of the agricultural production folk-custom; There are massive materials
that reflect the agricultural production custom of Tang and Five Dynasties and Earily
Song Dynasties in Dunhuang, which is valuable for researching the Dunhuang area
and even the formation and evolution of agricultural production in the ancient
northwest area.

teau the seeding season is cold and little
rainfall. Soil temperature,moisture and fertilizer is an important factor in crop yield. So in this
area dissemination conservation tillage of importance. Most of former researches in
comparison between conservation tillage and conventional tillage. This experimentation
compare with sereval conservation tillage's difference. Through this comparison, wind-water
erosion in the Loess Plateau ecologically fragile areas and application of a reasonable choice
of different measures to provide a reference of farming with a view to achieving the
sustainable and health development of agriculture. In this study, selection of test sites in the
Loess Plateau in northern China typical wind-water erosion area Shenmu, a no-tillage, straw
mulch, plastic film mulching, mulching ridge, ridge of the five kinds of different measures of
conservation tillage experiment, observe ground temperature,soil nutrients,soil moisture,yeild
and soil and water loss.
