Este trabalho avaliou tecnologias de ambientes protegidos e substratos para a produção de mudas de Dipteryx alata Vog. Foram utilizados dois ambientes protegidos: telado agrícola, fechamento em 90° graus, com tela preta nas laterais e aluminizada na cobertura, ambas de 50% de sombreamento; telado agrícola, fechamento em 45° graus, com tela preta nas laterais e cobertura, de 50% de sombreamento. Em cada ambiente foram testados substratos de mistura de esterco bovino (E) e vermiculita (V): 100% E + 0% V; 90% E + 10% V; 80% E + 20% V; 70% E + 30% V; 60% E + 40% V; 50% E + 50% V; 40% E + 60% V; 30% E + 70% V; 20% E + 80% V; 10% E + 90% V. O telado preto propiciou mudas de melhor qualidade e os substratos com baixas porcentagens de esterco (10, 20 e 30%) são os mais propícios para a formação de mudas de Dipteryx alata Vog.
This study evaluated the technologies of protected environments and substrates for the production of Dipteryx alata Vog. seedlings. Two protected environments were used: agricultural screened, closing at 90 degrees, with black screen on the sides and aluminized screen on the cover, both with 50% shading; agricultural screened, closing at 45 degrees, with black screen on the sides and cover, both with 50% shading. In each environment, substrates composed of mixture of cattle manure (E) and vermiculite (V) at the following ratios were tested: 100% E + 0% V; 90% E + 10% V; 80% E + 20% V; 70% E + 30% V; 60% E + 40% V; 50% E + 50% V; 40% E + 60% V; 30% E + 70%; 20% E + 80% V; 10% E + 90% V. The black screen environment propitiates seedlings of better quality and the substrates with low percentages of cattle manure (10, 20 and 30%) are the most propitious for the formation of Dipteryx alata Vog. seedlings.
