水曲柳个体生长节律及优良单株选择试验
|
摘要
对水曲柳个体树高生长节律进行了研究。结果表明:各个体生长期无明显差异,速生期均在5月中旬至6月下旬,速生期生长量占全年生长量的70%～80%;个体间树高当年生长量差异显著,其中134#、146#、121#高生长优势明显,全年高生长量分别为76.2 cm、73.9 cm和73.6 cm,分别是对照个体的194.4%、188.5%和187.8%。初步选择出134#、146#、121#为优良个体。
Through the study of the high growth rhythm of the families of Fraxinus mandshurica, result shows that there is no obvious difference in the growth period of each family. The fast-growing period is from mid May to late June, and the growth rate of the fast-growing period accounted for 70%-80%of the annual growth.The variance analysis shows that there are significant differences in annual growth of tree height among individuals families, and height growth of Fraxinus mandshurica '134#', Fraxinus mandshurica '146#', Fraxinus mandshurica '121#' have obvious advantage. The annual height growth is 76.2 cm, 73.9 cm & 73.6 cm,which is 194.4%, 188.5% & 187.8% of contrast individual plant,respectively.Preliminary selection of comprehensive growth description index of Fraxinus mandshurica '134~#', Fraxinus mandshurica '146~#'and Fraxinus mandshurica'121~#'were selected as excellent individuals.
