The experiment was conducted to the improvement of the soil alkali -salinity in songnen grassland, based the seed movement over thenaked alkali-saline soil, which is very important significance on theory and appliance, and at the same time, we also explore a new way to improve naked alkali-saline soil by inserting cornstalk.

By employing indicators as soil PH, conductance and salt content, different soil salinity degrees are plotted out. There arc 9 types of salinisation levels in Fukang oasis. Within them, the strong saline soil and solonchak are the main types, which, with regards to latitude and from the lower of diluvial fan to desert, distribute in turn as middle saline soil, strong saline soil, solonchak, strong saline soil, solonchak and non- saline distribute.

Experiments of bioremediation and control were conducted with the alkali meadow grass planted in saline soil for 3 years. Contrasted with control group, topsoil desalination rate was up to 77.00%; pH value decreased 0.25 pH unit; soil bulk density decreased 0.14 g/m^3; total porosity increased by 5.29%; soil aggregate structure increased by 23.14%; soil water content increased 70.30 g/kg; average triennial alkali grass yield was 36000 kg/hm^2. In addition, planting forage in saline soil as a medium and establishing a compound agro-forestry-animal system promoted the sound combination of planting industry, forestry, and livestock husbandry. Because of the reasons, utilization ratio of land reached more than 184.00%; the income of land increased from 16300 to 35500 yuan/hm^2 average income per farmer in the controlling region increased by 66.00%, from 2160.70 to 1300.80 yuan.
