Abstract

Triple heat preservation measure including single pipe film greenhouse，middle-arch shed，plastic film and straw were adopted to conduct the seedling experiments of Cinnamomum japonicum var. chenii. The results indicated that with the triple heat preservation technology，the average field germination was 84.5 per cent，10 per cent higher than the general open breeding，showing significant differences between the two ways of breeding. Moreover，the technology could greatly improve the air temperature and ground temperature for the seedling in early spring，promote the seedlings germination，prolong seedling growth period，and accelerate seedling growth. The average height growth of 1-year-old seedlings was 75.6 cm，which was 5.2 to 6.5 times that of the general breeding；the average diameter growth was up to 1.24 cm，3.4 to 4.4 times that of the general breeding. The heat preservation technology greatly increased the yield and quality of seedlings，avoided occurrence of low-quality seedlings，and brought significant economic benefits. The technology could be extended and applied in production. ［Ch，3 tab. 13 ref.］
