| 摘 要： | 本项研究主要在山东省冠县毛白杨林场进行,研究了毛白杨片林的林分生长规律、生物量积累及它们与土壤条件的关系。研究结果表明毛白杨生长量在不同土壤上差异甚大,其年平均材积生长量,壤质褐潮土>夹淤沙壤质潮土>通体沙质潮土>粘质褐潮土>风沙土;毛白杨片林数量成熟龄在壤质褐潮土为13a以后,其它几种肥力差的土壤为7-9 a;壤质褐潮土上毛白杨林速生期持续12 a以上,其它几种土壤为4-9 a。据观测毛白杨片林粗生长高峰期显著,5月份粗生长占全年总量40-60％。高生长高峰期持续期较长,为6-7月。毛白杨片林生物量积累随林龄增大而增加,尤其2-10 a增长速度最大,10-14 a以后生物量积累也有所增加,但增加速度减缓。

| Abstract: | The study was conducted at the Poplar Forest Farm of Guan County, Shandong Province. The result demonstrated the relationship between the law of growth of P. tomentosa and different kinds of soil condition. More knowledge about the bioecological characteristics of P. tomentosa will be of help to get high yield and better cultivation.P. tomentosa is a native tree species in China. It is mainly distributed over the middle and lower reaches of the Yellow River. They are planted in different kinds of soil in the old riverbed of ,the Yellow River in the western part of Shangdong Province. Their growth is closely related with different kinds of soil condition and their increments vary greatly. According to the results in terms of annual increment: its growth in Cinnamonic Chao soil with loam texture > that in Chao soil with silt loam texture > that in Chao soil with the whole sand texture > that in Cinnamonic Chao soil with clay texture > that in Wind-sand soil. It's growth in volume in Cinnamonic Chao soil with loam texture is 4 times as much as that in Wind-sand soil.Mature age of P. tomentosa stand in Chao soil with loam texture is 13 years after plantation, but in the other kinds of impoverished soil is from 7-9 years. The fast-growing period may continue for more than 12 years for the Stand in Chao soil with loam texture, while in other kinds of soil, it may continue from 4-9 years. Observations have been made in the fixed plots. The peak growth stage in thickness is obvious, the growth in thickness appears in May every year, making up 40%-60% increase of the total in the whole year. The peak growth in height occurs from June to July every year.The increment of P. tomentosa stand raises with the increase of age of the stand. It grows fast from the second to the tenth year, then slows down gradually. It's increment slows down after 10-14 year. |
