To study effects of the planting pattern and the planting density on the yield and its characters of rice planted in saline soil in Western Liaoning, in this paper,3 transplanting densities with film-covering ＆ transplanting by machine and transplanting by machine were tested. The results were as follows. The rice could grow earlier and faster in film-covering field than in bare field. With grain number per panicle, setting rate, 1,000-grain weight and the number of effective panicle being higher, film-covering rice had higher yield. Rice yield and its characters were significantly different between 3 transplanting densities, further, the yield and effective panicle number would increase with the transplanting density getting larger. As a conclusion, the proper larger transplanting density can promote the rice yield in saline soil,＆ the better density of rice planted in film-covering saline soil in Western Liaoning is the planting-space 10-16 cm with row space 30 cm.
