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(452mg/g)>N(35mg/g)>K(8439.9μg/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);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%)。
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 (8439.9μg/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 ( 19.4 μg/g) ; nutrient allocation patterns in mature sporophyte followed theorder: 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%).
