Abstract: In order to solve the damage effects of traditional plastic seedling tray on farmland,reduce white pollution and adverse environmental impacts caused by the burning of straw, taking straw seedling cultivation plate （T）,hard disk （CK₁）,conventional seedling soil mixed with sawdust seedling cultivation plate（CK₂） and sand mixed sawdust seedling （CK₃） as the test object,the effects of straw seedling cultivation plate on rice（Oryza sativa L.） seedling quality, yield, the production cost and benefit was analyzed. The results showed that straw seedling cultivation plate can significantly improve the seedling quality,compared with CK₁,CK₂ and CK₃,the grain plumpness of rice under straw seedling cultivation plate increased 0.33、0.14、0.15 mg/cm,the yield increased by 19.6%、8.6% and 3.1%,and economic output increased of 3 838.5,1 668.6,383.3 CNY/hm²,respectively.

Key words: rice（Oryza sativa L.）, straw seedling cultivation plat, seedling quality, application effect
