摘要
采用实验生态学的方法,并通过方差分析,对6类不同岩性发育的土体上11年生马尾松生长和生物量研究,以揭示岩性—土壤与马尾松生产力的关系,其研究结果表明, 6类不同岩性发育的土体对马尾松的高、径生长及生物量效应影响不同,其中,长石石英砂岩平均树高536 04cm,平均胸径4 86cm,平均单株生物量5 230kg;玄武岩平均树高512 24cm,平均胸径4 73cm,平均单株生物量5 222kg,生长良好,其下依次是石英砂岩、变余砂岩、第四纪红色黏土和煤系硅质砂页岩,且后两类岩性差异较小;与马尾松高、径生长显著相关的土体化学因子,均仅是pH值,且呈负相关。
Adopted the method of experimental ecology and analysis of variance, the biomass and growth of planting (eleven) years’ Masson pine on the soils from six lithological characters were studied in order to reveal relationship between lithological character-soil and productivity of Masson pine, and establish foundation of systemic management Masson pine fast-growing and high yield plantation. The main results were as follows: The effect of soil from six lithological characters on the height, diameter growth and biomass of Masson pine was different, in which the growth order of Masson pine was: Feldspathic quartzy sandstone (average height 536 04cm, average diameter 4 86cm, average individual biomass 5 230kg)>Basalt>Quartzy sandstone>Metamorphic sandstone>The Quarternary Period red clay>Coal measures siliceous sand-shale, and the difference was smaller in the last two lithological characters. The significant relationship between the height, diameter growth of Masson pine and the chemical characters of soil was analysed, which indicated that the height, diameter growth were negatively related to pH.
