亚马逊雨林的可持续管理是支持地球生命的基础,因为它在固碳方面发挥了关键作用。在森林中生长的物种之一是açaí(Euterpeoleracea),这是其居民的重要食物和收入来源。阿卡伊的种子,由于水果的加工,是固体有机残留物,这是一个不受欢迎的环境影响的代理,如自然景观的修改,堵塞下水道和水道,地表水富营养化。在这项研究中,我们评估了在质朴的烤箱中使用木片作为能源来生产acai生物炭,以便家庭农民对残留物进行可持续管理,并使用生物炭来改善土壤质量并生产本地植物的幼苗以再生退化的森林。实验是在帕拉进行的,巴西,亚马逊地区,使用随机完整的区组设计。实施了由四种生物炭粒径(3、5、7和12mm)组成的阶乘处理结构,4个应用率(4、8、16和32tha-1),和无生物炭的控制,5次重复。结果表明,该生物炭生产方法易于应用,成本较低,允许家庭农民使用它。生物炭率和粒径的组合以不同方式影响土壤性质和黑胡椒幼苗的发展。受影响的土壤特性是保水能力,水分,荧光素二乙酸酯水解和芳基硫酸酯酶活性。受影响的黑胡椒幼苗的生长参数为高度和根系发育。
Sustainable management of the Amazon rainforest is fundamental for supporting life on earth because of its crucial role in sequestering carbon. One of the species grown in the forest is açaí (Euterpe oleracea), which is an important food and income source for its inhabitant. The acai seed, resulting from the processing of the fruit, is a solid organic residue, which has been an agent of undesirable environmental impacts such as natural landscape modifications, clogging sewers and water courses, eutrophication of surface waters. In this research, we evaluated the use of wood chips as a source of energy in a rustic oven to produce acai biochar so that family farmers carry out sustainable management of the residue and use biochar to improve soil quality and produce seedlings of native plants to regenerate degraded forests. The experiment was conducted in Pará, Brazil, Amazon region, using a randomized complete block design. A factorial treatment structure was implemented consisting of four biochar particle sizes (3, 5, 7, and 12 mm), 4 application rates (4, 8, 16, and 32 t ha-1), and a biochar-free control, with 5 replications. The results showed that the methodology for biochar production was easy to apply and low cost, allowing its use by family farmers. The combination of biochar rate and particle size affected soil properties and the development of black pepper seedlings in different ways. The soil properties affected were water retention capacity, moisture, fluorescein diacetate hydrolysis and arylsulphatase activity. The growth parameters of the affected black pepper seedlings were height and root system development.
