“…However, in all those studies the weeds were crowned with hoe before placing the cardboard, which involves additional labor costs. The importance of controlling grasses in reforestation projects aims to obtain greater growth and survival gains for tree species (Ammondt & Litton, 2012;Dias et al, 2016;Santos et al, 2019). Gonçalves et al (2018) demonstrated that manual crowning of seedlings can be replaced by crowning with cardboard without hindering growth and with the benefit of reducing seedling mortality.…”

“…One of the greatest benefits of crowning seedlings with cardboard can be related to the lower cost of operation compared to traditional manual crowning, although the quality of the cardboard and the volume of rainfall in the area can increase these costs (Dias et al, 2019). In a study carried out in a riparian forest in the Atlantic Forest biome, the use of cardboard cut the working time in half (Palhares, 2011).…”

“…In Rio de Janeiro state, southeast Brazil, reforestation costs per hectare of Atlantic Forest can exceed U$ 6.500,00, due to the necessary threeyear maintenance period for planted areas, including 8 to 12 interventions, involving crowning of seedlings and mowing (Leles et al, 2015). These operations are frequently neglected due to either difficulty with access or to the high costs involved, often leading to reforestation failure (Toledo et al, 1996;Wittenberg & Cock, 2001;Monquero et al, 2011;Santos et al, 2019).…”

Invasive exotic grasses are among the biggest obstacles to the success of reforestation projects. The aim of this study was to evaluate the efficiency of the crowning with cardboard in suppressing the grasses Urochloa humidicola and Megathyrsus maximus aiming its use in reforestation areas. A field experiment was installed in a completely randomized design with two treatments consisted of crowning with cardboard and without crowning (control). The crowning with cardboard caused a progressive reduction of the biomass and was effective in causing senescence of both grasses in 80% or more of the crowning area between 20 and 50 days after the crowning (F test; p<0,05). These results demonstrate the effectiveness and potential of using the crowning with cardboard to control alien grass species in reforestation areas. This method brings as an innovation the possibility of placing cardboard directly on the grass after mowing, allowing greater simplicity and lower operating cost.

“…Assim, a criação de novas tecnologias tem sido uma prioridade nas pesquisas de restauração. Por exemplo, o disco ou placa de papelão, que é um dispositivo usado no coroamento de mudas, pode reduzir a incidência da matocompetição nos primeiros anos de plantio, além de substituir o coroamento convencional que pode demandar maior investimento de recursos (Dias et al, 2019). Por outro lado, a manta geotêxtil tem sido usada como alternativa para reduzir o nível de infestação de plantas daninhas e sua influência negativa sobre a sobrevivência e crescimento das espécies arbóreas plantadas ou provenientes da regeneração natural (Polster, 2002;Artioli & Correa, 2019).…”

Este estudo teve como objetivo testar a eficiência do uso de um novo equipamento denominado nucleário, na sobrevivência e crescimento de mudas de espécies arbóreas visando à restauração florestal em áreas atingidas pelo rejeito da barragem de Fundão, em Mariana, MG. Foram avaliadas, por 12 meses, duas espécies arbóreas nativas (Piptadenia gonoacantha (Mart.) J.F. Macbr. e Inga edulis Mart.), sob um desenho de blocos aleatorizados e três tratamentos: hidrogel (T1), nucleário (T2) e controle (T3). Analisou-se o efeito dos tratamentos e do tempo após o plantio sobre a sobrevivência e crescimento das mudas, por comparação múltipla de médias e modelos lineares mistos. Foram observadas diferenças significativas de crescimento em altura e em diâmetro ao nível do solo (DNS) entre os tratamentos. As taxas de crescimento relativo para altura e DNS das duas espécies se mantiveram relativamente constantes, sem diferenças entre os tratamentos. Constatou-se que I. edulis apresentou sobrevivência maior na presença do nucleário, em comparação com os demais tratamentos. Os resultados indicam que apenas o uso de nucleários não foi suficiente para garantir o bom desenvolvimento e sobrevivência das mudas em campo, sendo recomendada sua avaliação para outras espécies arbóreas nativas.

Organic mulching has been suggested as an option for managing spontaneous species in restoration plantings and can promote improvements in soil properties and performance of planted species. The aim of this study was to test the effect of crowning techniques on soil microclimatic and performance of forest seedlings. The experiment was carried out in Goiás state, Brazil. Two study factors were used: crowning techniques (manual weeding, cardboard, wood chipping and control—without weed competition management), and six tree species: Anadenanthera peregrina, Ceiba speciosa, Dipteryx alata, Inga edulis, Genipa americana and Spondias mombin. Soil temperature and moisture assessments were performed within the crowning area (0.25 m2). Seedling survival and growth in height and diameter were evaluated over 219 days. Organic mulching treatments of wood chipping and cardboard provided increase in soil moisture and decrease in temperature, resulting in higher seedling survival rate. The increase in height and diameter differed among species under study, with A. peregrina standing out in height and C. speciosa in diameter. The crowning techniques did not influence the average height of species; however, wood chipping provided greater diameter increase. The findings of this study indicate that mulching treatments, by contributing to increase soil moisture and decrease soil temperature, can be used as crowning techniques to increase the survival rate and diameter growth of tree species in restoration plantings.
