Abstract

Coffee husk is the main waste of coffee bean production using a dry processing system. Coffee husk is returned to the coffee plantation as mulch, or used as a mixture for nursery media and for making bio-charcoal. This study aims to determine the effect of the formulation of biochar, coffee husk, and soil on the growth of Arabica coffee seedlings. The experiment used a randomized block design (RBD) consisting of 6 treatments with 4 replications. The treatments were the composition of the ratio of biochar: coffee husk: soil (v / v / v), namely: 0: 1: 2 (control, without biochar), 1: 1: 2, 1: 0: 2 (without coffee skin), 2: 1: 2, 1: 2: 2, and 1: 1: 1. The coffee husk biochar is made by a slow burning system in a stack. The results showed that: (1) The treatment of biochar composition, coffee husk and soil had an effect on the number of leaves, length x leaf width, crown dry weight, fresh weight quality index, and dry weight quality index; (2) biochar mixing treatment did not increase seedling growth. Mixing biochar with a composition of 1: 1: 2 reduces root growth; (3) the composition of biochar, coffee husk and soil 1: 1: 2 gave better seedling growth than the composition 0: 1: 2 (control without biochar) based on the quality index of fresh seedling and dry seedling.Keywords: Arabica, biochar, coffee husk, growth, seedling, quality indeces

生物化学配方和皮肤废物对咖啡种子生长的影响

咖啡皮是使用干法加工系统生产咖啡豆的主要废物。咖啡壳被送回咖啡种植园作为护根物，或用作苗圃介质和制造生物炭的混合物。本研究旨在确定生物炭、咖啡壳和土壤的配方对阿拉比卡咖啡幼苗生长的影响。试验采用随机区组设计(RBD)，共6个处理，4个重复。生物炭:咖啡皮:土壤的比例(v / v / v)分别为:0:1:1:2(对照，不加生物炭)、1:1:2、1:1:2(不加咖啡皮)、2:1:2、1:1:2和1:1:1。咖啡壳生物炭是由一个缓慢燃烧的系统在一个堆栈。结果表明:(1)生物炭组成、咖啡壳和土壤处理对咖啡叶数、长×叶宽、冠干重、鲜重品质指数和干重品质指数均有影响;(2)混合生物炭处理对幼苗生长没有促进作用。将生物炭与1:1:2的成分混合会减少根的生长;(3)从鲜苗和干苗质量指标看，生物炭、咖啡皮和土壤1:1∶2的组合比0∶1:1∶2(无生物炭对照)的幼苗生长更好。关键词:阿拉比卡咖啡，生物炭，咖啡皮，生长，幼苗，品质指标
