高节竹地上器官氮、磷、钾含量及积累特性
|
摘要
2017年8月,对浙江省桐庐县人工种植的1~5 a的高节竹纯林采用全收获法测定不同年龄段的高节竹地上部生物量,并测定高节竹的叶、枝、秆的氮、磷、钾含量。结果表明,高节竹地上部分器官中氮、磷、钾含量大小顺序均表现为:叶>枝>秆,叶、枝、秆中氮平均含量为20.48、7.48、3.62 g·kg~(-1),磷平均含量为0.87、0.63、0.48 g·kg~(-1),钾平均含量为13.02、6.00、4.85 g·kg~(-1)。高节竹地上部各器官氮、磷、钾积累总量为294.90 kg·hm~(-2),大小顺序为:秆(142.16 kg·hm~(-2))>叶(93.51 kg·hm~(-2))>枝(59.23 kg·hm~(-2));不同营养元素的积累量大小为:氮(141.97 kg·hm~(-2))>钾(140.06kg·hm~(-2))>磷(12.88 kg·hm~(-2))。氮素在叶、秆中分配率均为39.2%,磷、钾在秆中的分配率则分别为60.1%、56.2%。
In August 2017,the plant biomass in different organs was measured by the whole harvest method of Phyllostachys prominens forest of 1 a~5 a planted in Tonglu County of Zhejiang Province,and were collected for lab analysis of the contents of N,P,K in leaves,branches and culms.The results showed that of N,P,K in different organs distribution of patterns indicated that leaf>branch>culm.The content of N,P,K in leaf,branch and culm was 20.48,7.48,3.62 g·kg~(-1),0.87,0.63,0.48 g·kg~(-1)and13.02,6.00,4.85 g·kg~(-1).The nutrient accumulation of Phyllostachys prominens in above-ground was 294.90 kg·hm~(-2),its nutrient accumulation followed the order:culm(142.16 kg·hm~(-2))>leaf(93.51 kg·hm~(-2))>branch(59.23 kg·hm~(-2)),each element accumulation in order for N(141.97 kg·hm~(-2))>K(140.06 kg·hm~(-2))>P(12.88 kg·hm~(-2)).Distribution ration of N was 39.2%in the leaf and culm,distribution ration of P and K was 60.1%,56.2%in culm.
