| 摘要: |
| 采集广西忻城县红渡镇金银花(Lonicera japonica)种植示范区人工栽培3年生的金银花样品,测定生物量及各器官的主要元素含量,并估算金银花的经济效益。结果表明,金银花的生物生产力是藤茎(0.79t·hm-2·a-1) > 叶子(0.40t·hm-2·a-1) > 根(0.33 t·hm-2·a-1) > 花(0.30 t·hm-2·a-1);金银花的主要元素(N、P、K)平均含量显示花(5.68 kg.hm-2) > 叶子(4.60kg.hm-2) > 藤茎(3.06kg.hm-2) > 根(2.93 t·hm-2);金银花年均产干花1.78 t·hm-2,年均经济收入每公顷35600元。 |

| Abstract: |
| Samples of 3-year old Lonicera japonica were collected from Hongdu town,Xincheng County,which is a cultivative demonstration area in Guangxi.Biomass and contents of elements were made and economic benefits of cultivated Lonicera japonica was investigated.The results showed that:(1) The net biomass of vine and its branches were 0.79t·hm-2·a-1,and the leaves were 0.40t·hm-2·a-1,root were 0.33t·hm-2·a-1,flowers were 0.30t·hm-2·a-1;(2) The mean contents of main elements(N,P,K) of flower,leaves,vines and roots were 5.68kg·hm-2,4.60kg·hm-2,3.06 kg·hm-2 and 2.93 kg·hm-2,respectively;(3) The mean dry flowers yield was 1.78t·hm-2·a-1,mean income was 35600 Yuan·hm-2·a-1. |
