| 摘 要： | 对２０个杉木不同家系的苗木进行磷素营养要求试验，１年生苗木盆栽试验结果表明：杉木不同家系苗木对磷素营养反应敏感，２ｇ磷处理使苗高、地径分别增益３．７％—９６．５％、７．４％—６１．１％，４ｇ磷处理使苗高、地径分别增益２．１％—８３．１％、３．７％—５７．９％，杉木苗期需要磷素营养。三明３８、三明６７、三明４８、三明５８四个家系生长比较理想，在０ｇ磷处理下，１年生平均苗高１３．０—１５．９９ｃｍ，平均地径０．２３—０．２７ｃｍ，这４个家系具有更大的生长潜力，２０个家系间对磷素营养要求方面不存在显著的差异。

| Abstract: | An experiment was conducted on the phosphorus nutrient
requirement of the seedlings of 20different families of Cunninghamia lanceolata. The results
indicated that(1)the phosphorus nutrient wasneeded by C. lanceolata at a seedling
stage;and(2)the growth of four families of Sanming38,Sanming67,Sanming48 and Sanming58
was relatively ideal. the average height of 1-year-old seedlings was 13.0 15.99cmand the
average ground diameter of 1-year-old seedlings was 0.23 0.27cm under the treatment of 0g of
