In this study,maize was transplanted by the straw seedling-raising pot under three density treatments,single,double,three per pot,to delay the crop growing period,and realized double harvest planting in one year.

Analyze that the shortage of resources,the difficulty to levelin g field and the sufficient labor in rice areas are the brief factors that limit c ontinually expanding the areas of bowl plate seeding and throwing seedlings.

The degradable straw seedling nursing container is attracted more and more attention of the planter,because it can be planted through the earth bowl and the seedling.

The experiment of seedling raised in small nutritional pot was conducted in field with different transplanting date.
