Download or read book Diseno y evaluacion de un sistema de cultivo hidroponico para la produccion de hortalizas a nivel domestico written by Francisco Roberto Castaneda del Cid and published by . This book was released on 1997 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: La dieta diaria de grupos poblacionales ubicados en areas marginales tanto en el area urbana como en el area marginal no incluye en general a las hortalizas, las cuales son una rica fuente de vitaminas y minerales. Ademas, las hortalizas pueden cultivarse en forma intensiva, efectiva y eficiente, el cutlivo de hortalizas no solo puede mejorar la disponibilidad y acceso de los alimentos, sino tambien ser una fuente de ingresos. La hidroponia ofrece una alternativa para el cultivo de estos vegetales. La finalidad de este trabajo es: disenar y evaluar un sistema de cultivo hidroponico para la produccion de hortalizas a nivel domestico, que sea viable tecnica y economicamente, para ser implementado por estas personas, sin necesidad de que cuenten con conocimientos de agricultura, quimica o matematicas. Los cultivos hidroponicos o hidroponia, como se conoce a esta tecnologia, no es mas que la produccion de plantas sin hacer uso de la tierra o suelo, utilizando como medio de crecimiento de la raiz un material inerte llamado sustrato al cual se le agregan, en forma de solucion, todos los nutrientes necesarios para el desarrollo de los vegetales. El sistema disenado se baso en experiencias previas realizadas en otros paises como Nicaragua, Costa Rica, Colombia y Chile, con adaptaciones al ambito socioeconomico de Guatemala. Para el diseno de este sistema hidroponico, el trabajo se dividio en cinco etapas: Primera etapa: analisis de sustratos. Segunda etapa: solucion de nutrientes hidroponicos. Tercera etapa: sistemas de cultivo hidroponico. Cuarta etapa: efectos del sustrato y la concentracion de la solucion de nutrientes, sobre el rendimiento y calidad de los cultivos. Quinta etapa: analisis economico de los cultivos hidroponicos. En la primera etapa se realizo un sondeo de los posibles materiales existentes en la ciudad de Guatemala, que podian servir como sustratos, luego de descartar varios de ellos se determino que la arena de rio, la piedra pomez y la cascarilla de arroz, eran convenientes. Luego se realizaron mezclas de estos tres sustratos para hacerles analisis fisicos y quimicos llegandose a encontrar tres sustratos con distintas cualidades de los cuales servirian para posteriores analisis, los sustratos fueron los siguientes: S1' Arena de rio, S2' Cascarilla de arroz, S3' Arena de rio (25 por ciento) + Piedra pomez (25 por ciento) + Cascarilla de arroz (50 por ciento) ...

Book Nanotechnology and Plant Sciences

Download or read book Nanotechnology and Plant Sciences written by Manzer H. Siddiqui and published by Springer. This book was released on 2015-01-27 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a holistic view of the complex and dynamic responses of plants to nanoparticles, the signal transduction mechanisms involved, and the regulation of gene expression. Further, it addresses the phytosynthesis of nanoparticles, the role of nanoparticles in the antioxidant systems of plants and agriculture, the beneficial and harmful effects of nanoparticles on plants, and the application of nanoparticles and nanotubes to mass spectrometry, aiming ultimately at an analysis of the metabolomics of plants. The growing numbers of inventions in the field of nanotechnology are producing novel applications in the fields of biotechnology and agriculture. Nanoparticles have received much attention because of the unique physico-chemical properties of these compounds. In the life sciences, nanoparticles are used as “smart” delivery systems, prompting the Nobel Prize winner P. Ehrlich to refer to these compounds as “magic bullets.” Nanoparticles also play an important role in agriculture as compound fertilizers and nano-pesticides, acting as chemical delivery agents that target molecules to specific cellular organelles in plants. The influence of nanoparticles on plant growth and development, however, remains to be investigated. Lastly, this book reveals the research gaps that must be bridged in the years to come in order to achieve larger goals concerning the applications of nanotechnology in the plants sciences. In the 21st century, nanotechnology has become a rapidly emerging branch of science. In the world of physical sciences, nanotechnological tools have been exploited for a broad range of applications. In recent years, nanoparticles have also proven useful in several branches of the life sciences. In particular, nanotechnology has been employed in drug delivery and related applications in medicine.

Download or read book Transport in Plants I written by M.H. Zimmermann and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 548 pages. Available in PDF, EPUB and Kindle. Book excerpt: When WILHELM RUHLAND developed his plan for an Encyclopedia of Plant Physiol ogy more than three decades ago, biology could still be conveniently subdivided into classical areas. Even within plant physiology, subdivisions were not too difficult to make, and general principles could be covered sufficiently in the two introductory volumes of the Encyclopedia on the physical and chemical basis of cell biology. But the situation changed rapidly even during the 12-year publication period of the Encyclopedia (1955-1967). The new molecular direction of genetics and structural research on biopolymers had an integrating effect on all other biological fields, including plant physiology, and it became increasingly difficult to keep previously distinct areas separated. RUHLAND'S overall plan included 18 volumes and about 22,000 pages. It covered the entire field of plant physiology, in most cases from the very beginning. But, as each volume appeared, it was clear that its content would soon be outdated.
