摘要
为探讨咖啡内壳作为林木育苗基质的可行性,以无机氮肥、粪肥及微生物菌剂等为调理剂,按物料及物料配比的不同,配制成以咖啡内壳为主要原料的7个育苗基质配方,研究使用无纺布育苗成型机的咖啡内壳容器基质对思茅松幼苗生长的影响。结果表明:不同配比的基质对思茅松苗苗高、地径、主根长、侧根数、生物量等苗木形态指标影响显著;从苗木质量指标QI和苗木矿质营养含量综合考虑,筛选出V(咖啡内壳)∶V(牛粪)=4∶1配置成的基质,以及按照咖啡内壳中混配酵素菌0.5 kg/m^3、过磷酸钙1.25 kg/m^3的配比组合经堆肥化处理的基质,适宜用作思茅松的优良育苗基质。
To study the feasibility of taking composted coffee seed-coat as seedling substrates for trees, 7 kinds of nursery substrates which were added inorganic nitrogen fertilizer, farmyard manure and microbial agents as amendment. Aiming at studying the influences of the coffee seed-coat container substrates on the quality of Pinus kesiya var. langbianensis seedlings. Results indicated that there were significantly impact among the indicators of seedling height, ground diameter, main root length, number of lateral root and biomass. Considering the QI and mineral nutrition in the seedlings, the 2 proportions could be applied preferably for culturing container seedlings. One substrate was mixed by V （ coffee seed-coat） ： V （ cow dung） = 4 ： 1, and another was mixed by enzyme 0.5 kg and super-phosphate 1.25 kg/m3 of coffee seed-coat.
