Relation of Meteorological Factors with Growth, Yield and Value of Flue-cured Tobacco in Young Seedlings Transplanting Modes Under to Above Film

To explore the transplanted pattern meteorological foundation, a set of 10 field experiments that including the pattern of 5 leaves age young seedling transplant modes under plastic mulching (YSTUPM) and 12 leaves age conventional pattern above plastic mulching (CPAPM) was conducted to analyze the relation of meteorological factors with the growth period, economic characteristics. The results showed that (1) There were the positively correlations, which day after transplanted (DAT) to root spreading stage with product of accumulation value of air temperature and sunshine hours ( r=0.727**) and accumulation value of sunshine hours in the fast growing period ( r=0.710**), DAT with daily mean of sunshine hours ( r =0.673*) and accumulation value of sunshine hours in the maturity stage (r=0.675*); While the negatively correlations, which DAT with daily mean of rainfall ( r =-0.723**), product by daily mean of air temperature and sunshine hours and rainfall (r =-0.764**), accumulation value of air temperature in the fast growing period ( r =-0.693*). (2) There were the close correlations between the economic characteristics with the meteorological factors, Which in the whole field growing duration, which yield with daily mean of air temperature ( r =0.773**), accumulation values of air temperature ( r =0.880**), product by daily mean of air temperature and sunshine hours (r =0.888**); value with product by daily mean of air temperature and sunshine hours ( r=0.825**), product by accumulation value of air temperature and sunshine hours ( r=0.707*), accumulation values of air temperature ( r=0.880**). while price were negatively correlations with daily mean of air temperature ( r =-0.926**), accumulation values of air temperature ( r =-0.745**), product by daily mean of air temperature and sunshine hours and rainfall ( r =-0.590*), product by accumulation value of air temperature and sunshine hours and rainfall ( r =-0.666*); the middle leaf with product by daily mean of air temperature and sunshine hours and rainfall ( r =-0.601*). In the fast growing period, super leaf rate with product by accumulation value of air temperature and sunshine hours (r =0.629*), while the middle leaf rate with product by accumulation value of air temperature and sunshine hours ( r =-0.653*)
