Greenhouse & Protected Agriculture
Las pérdidas de producción ocasionadas por el asoleado de frutos en manzanas y peras son elevadas en la mayoría de las regiones frutícolas del mundo. Evaluaciones locales indicaron para la temporada 2002-03 pérdidas de calidad de manzanas exportables de entre un 15 y 55 % según la variedad, determinando una sustancial merma tanto en la cantidad como en la calidad de fruta exportable y comercializable.
Everyone seems to be searching for the ideal plant mix. The criteria are simple: make a mix with good aeration, that doesn’t dry out too quickly, can be used in all cell sizes, contains all the nutrients necessary, can be used for all species of and stores indefinitely. All that is needed is a substrate that is not affected by other forces in the greenhouse; a mix that does not change with cultural practices. Obviously, trying to make the mix totally responsible for air, water and nutrition will be unsuccessful.
High tunnels are valuable assets to growers enabling them to produce high yields of quality horticultural crops. However, different strategies and more detailed management are required with this method of production. The objective of this workbook is to provide growers with the information and resources to use high tunnels effectively, enhance productivity and net income, and learn from the experience of other high tunnel users.

High tunnels, also referred to as “hoop houses,” are simple, plastic-covered, passive solar-heated structures in which crops are grown in the ground. High tunnels resemble greenhouses, but are less expensive to construct and maintain. Fruit and vegetable growers use them to extend the growing season and intensify production in cold climates. The advantages of growing crops in high tunnels rather than in fields are:
