Wang Fahong,Liu Shijun,Wang Xuqing,Ren Dechang & Cao Hongxin (Crop Institute,Shandong Academy of Agricultural Sciences,Jinan 250100)  
The results from several locations with different eco-environments in Shandong Province showed that,compared with the conventional planting system,the advantages of the bed-planting culture are as follows First,it can not only save irrigation water by 40%,but also significantly improve the soil physical property because of changing the flooding irrigation into small-canal irrigation Second,the bed-planting system can greatly improve the lodging-resistance,disease-resistance of wheat and the climate conditions of wheat canopy,such as increasing sunlight reception because of changing flat-planting to bed-planting Finally,the bed-planting system is also beneficial to demonstrating the advantage from bordering-wheat For example,it makes the grain weight raise by 5% and the yield by 10%
