杉木播种苗生长量和生物量动态研究

Studies on the Growth and Biomass Dynamics of Cunninghamia lanceolata Sowing Plants

在杉木一般产区（安溪） 进行２ 年的播种育苗重复试验， 结果表明， １ 年生杉苗生长规律基本一致， 生物量增长与苗高、地径成正相关， 苗木根系速生期比苗高、地径推迟１ 个月， 苗高、地径与苗木生物量成正相关。

The results indicate that the growth law of 1 year old plants of Cunninghamia lanceolata is basically identical;the biomass increase assumes the positive correlation with the plant height and ground diameter;the fast growing period of the plant root system is one month later than that of the plant height and ground diameter;and the plant height and ground diameter assume the positive correlation with the plant biomass.
