杉木不同优良品种苗期对比研究

Contrast between Different Superior Varieties of Cunninghamia lanceolata at Seedling Stage

在福建省将乐国有林场对不同种源的6个杉木优良品种进行了苗期对比试验。通过对苗高、地径、高径比及苗木质量分级的分析结果表明,参试杉木优良品种播种品质优良,苗木生长良好,质量高;苗高、地径、高径比在各品种苗木间差异达到极显著或显著水平;广西融水杉木种源种子是苗期表现最为优良的杉木品种。

Test of contrast between 6 superior varieties of Cunningharnia lanceolata at seedling stage was finished. Through the analysis of seedling height, ground diameter, seedling height/diameter, and seedling quality classification, the results showed that sowed seeding quality was fine for tested C. lanceolata fine variety, seedling grew fine, the quality was high; The differences among seedling height, ground diameter and seedling height/diameter of different seedlings reached extremely significant or significant level; C. lanceolata provenance seeds from Rongshui in Guangxi were the best varieties at seedling stage.
