摘要： 为了揭示尖叶拟船叶藓营养元素生殖配置规律, 本文对其12 种营养元素的生殖配置格局和季节动态进行了研究。其结果如下: 成熟孢子体的生物量配置为6 . 67% ; 在成熟孢子体中12 种营养元素的含量顺序是: C (452 mg/g) > N ( 35 mg/g) > K ( 8439. 9 μg/g) > Ca ( 7012. 9 μg/g) > P ( 2129 .2 μg/g) > Mg( 1482 . 9μg/g) > Na ( 432 . 9μg/g) > Mn ( 196 . 3μg/g) > Fe (177 . 7μg/g) > Al (174 .8μg/g) > Zn (68. 1μg/g)> Cu (19. 4μg/g) ; 成熟孢子体中营养元素生殖配置顺序是: K (17 .7%) > P (15 . 1% ) > Cu ( 13 . 3% ) > N(11 . 6% ) > Na ( 10 .5%) > Mn ( 7. 8% ) > Zn ( 7. 5%) > C ( 6. 9%) > Mg ( 6 .8% ) > Ca (5 . 4% ) > Fe(1. 3%) > Al (1 . 2% )。

Abstract: In order to reveal the reproductive patterns of Dolichomitriopsis diversiformis, twelve nutrients allocation patterns and seasonal dynamics were studied . The results were as follows: mature sporophyte biomass allocation was 6 . 67% ; 12 nutrient contents in mature sporophyte followed the order : C ( 452 mg/g) > N (35 mg/g) > K ( 8439. 9 μg/g) > Ca(7012 . 9μg/g) > P (2129.2μg/g) > Mg (1482 . 9μg/g) > Na (432 . 9μg/g) > Mn (196 . 3μg/g) > Fe (177.7μg/g) > Al (174 . 8μg/g) > Zn (68 . 1μg/g) > Cu (19. 4μg/g) ; nutrient allocation patterns in mature sporophyte followed the order : K (17. 7% ) > P (15.1% ) > Cu ( 13. 3%) > N (11. 6% ) > Na (10. 5% ) > Mn (7. 8% ) > Zn(7. 5%) > C (6.9% ) > Mg (6. 8% ) > Ca (5. 4%) > Fe (1.3%) > Al (1.2% ) .
