The quadratic polynomial equation simulation was applied for formula data of soilless and dry seedling breeding with transplanting vector and antagonism,and used partial correlation and path analysis on selected statistically significant factor.

Taking the local rice variety Shashani as control,a rice variety screening experiment was conducted with Kendao 10,Songjing 6 and Ha 99 as entries through two-stage seedling nurturing.

In order to make the late variety grow normally,a research o n rice two-stages seeding was made,which is sowing seeds indoor or in green ho use and transplanting into film-house when the young plants grow to a certain h eight.
