Caracterización física y micromorfología de materiales orgánicos e inorgánicos para la generación de mezclas de sustratos en la producción de lisiathus (Eustoma grandiflorum)
Provedor de dados: 32
Autores: Anicua Sánchez, Rosa.
La producción de cultivos en maceta está relacionada con la selección de sustratos, que se basa en las propiedades físicas y en particular con el tamaño y la distribución de partículas, que determinan la retención y el movimiento de agua. Por lo que, el objetivo del presente trabajo fue la caracterización de materiales orgánicos e inorgánicos a partir de las propiedades físicas y micromorfológicas para la generación de mezclas en la producción  de Lisianthus. Se realizó la caracterización de sustratos orgánicos (fibra de coco, peat moss, composta y vermicomposta) e inorgánicos (tezontle, piedra pómez, perlita y zeolita); con base en las propiedades físicas como densidad aparente (DA) y densidad real (DR) (Ansorena, 1994); espacio poroso total (EPT),...

The identification of alternative substrates that are suitable for the production of potted plants is very important. To this end, we studied the influence of different substrates on the growth and production of potted chrysanthemum (Dendranthema grandiflora Tzvelev cv. Funny). A completely randomized design with four treatments and twelve replicates was used. Each treatment consisted of the following substrates: i) carbonized rice husks; ii) commercial substrate; iii) mixture of vermiculite and carbonized rice husks in a 1:1 proportion; and iv) mixture of vermiculite and washed sand in a 1:1 proportion. Satisfactory results were obtained with alternative substrates, indicating that rice husks can be used as a sole or partial substrate for potted...

Provedor de dados: 52
Autores: Faria,Ricardo Tadeu de; Rego,Luciana do Valle; Bernardi,Anderson; Molinari,Hugo.
Two native Brazilian orchid especies, Oncidium baueri and Maxillaria picta, were grown in different substrate mixtures. The plants were cultivated in ceramic pots in a greenhouse with 50% of shadind light and watered three times a week. The following substrates were used: 1) de-fibered xaxim; 2)xaxim cubes; 3) vermiculite; 4) carbonized rice husk; 5) charcoal; 6) charcoal + carbonized rice husk; 7) crocks; 8) vermiculite and charcoal; 9) vermiculite + carbonized rice husks; 10) extruded polystyrene + charcoal; 11) pine bark + charcoal + extruded polystyrene; 12) vermiculite + carbonized rice husks + extruded polystyrene + charcoal; 13) pine bark. The substrate ratio was 1:1 in the mixture. NPK 10-10-10 leaf fertilizer was applied every thirty days and...

A.P. Restrepo, J. Garcia-Garcia, R. Moral, F. Vidal, M.D. Pérez-Murcia, M.A. Bustamante, and C. Paredes. 2013. A comparative cost analysis for using compost derived from anaerobic digestion as a peat substitute in a commercial plant nursery. Cien. Inv. Agr. 40(2): 253-264. The aim of this study was to evaluate the economic feasibility of using compost made from anaerobically digested cattle slurries in a commercial nursery. Using a comparative cost analysis, commercial peat substrate growing media has been partially substituted with increasing proportions of compost (25, 50 and 75% v/v of compost). This experiment was intended to establish the conditions under which the use of these composts is feasible and competitive relative to commercial peat, at both...
