Résumé
In order to restore the sandy soil,a double-film mulching technique is applied to the cultivation of desert rice.The un-restored sandy soil and the paddy soil planted by this technique were selected from 2014 to 2020 as the research object by comparing nutrient bridging in paddy soil,grassland,and desert.The variation in soil nitrogen(N),phosphorus(P),potassium(K),and organic matter(SOM)contents in sand and paddy soils of Horqin Naiman Qi were studied.Results showed that paddy soil N,P,K,and SOM contents increased with the increase of this technology application years.Compared to un-restored sandy soil,the content of soil total N in the paddy soil planted by double-film mulching technique increased by 230% ;total P content increased by 750% ;total K content increased by 100% ;SOM content increased by146%.Overall,the double-film mulching technique can improve the sandy paddy soil,restore the sandy land and provide the essential nutrients to the next generation of desert rice.At the same time in Liaoning University,in China,our research team gained experience regarding the Planting Rice with Double-Film Covering Technology.Overall,double-film mulching technique was a huge improvement of restoring the sandy land to Greenland,and providing the essential nutrients to the next generation of desert rice.Liaoning University conducted research on double-film mulching technique in the south of Horqin Sandy Land,Naiman Banner of Tongliao city,InnerMongolia where the climate conditions are similar to Mongolia.This inspired a lot to start a project of using Planting Rice with Double-Film Covering Technology to my country,Mongolia.
