| 中文摘要 | 针对金沙江流域元谋干热河谷退化旱坡山地环境人工经济林行间少优良草被覆盖问题,在乡土酸角Tamarindusindicalinn人工经济林6m×8m行间,开展了铺地木蓝IndigoferaendecaphyllaJacq适应引种栽培和生物量产出研究。测定其扦插出苗率、生根期、生长速度、株高、产草量、枯落物量和种子产量等指标,观察其抗逆性能,结果表明:铺地木蓝在金沙江干热河谷乡土酸角人工经济林行间适应性较好,具有速生、覆盖力强、耐瘠、耐旱、不攀缘和缠绕客体特点;全生育期内可刈割2次,留茬15cm,地面生物产量达31 5～40 5t/hm2;未刈割3年生铺地木蓝地面枯落物为6 3t/hm2,可采收种子968 8kg/hm2;适宜作为干热区退化旱坡山地人工经济林果行间覆盖作物推广,但规划种植时宜重视低温对其危害。 |
| 英文摘要 | In order to overcome the problem of uncovered area between rows under artificial economical forest in degraded slope land in dry-arid valley of Jingsha river,and find adaptability of introduced grass and biomass product,an experiment was carried out in agrestic Tamarindus indica linn space (6 m×8 m) by planting Indigofera endecaphylla Jacq.All the index,including germination percentage of seedling cutting,roots planting time,rate of growth,height of plant,grass biomass,litter amount and seeds yield and etc,were measured,and stress tolerance was observed also.Primary result showed:(i)Indigofera endecaphylla Jacq had the characters such as faster growth,stronger cover ability,tolerance to lower fertility,and drought,not climbing or enwinding objects;(ii)cutting two time during whole planting period,and 31.5-40.5 t/ ha·yr biomass could be harvested;(iii)litter amount about 6.3 t/ ha·yr could be obstained under ground of three years old Indigofera endecaphylla Jacq ,and seed about 968.8 kg/ ha could be harvested;(Ⅳ)Temperature under zero centigrade was harmful to Indigofera endecaphylla Jacq. |
