Método del cultivo hidropónico simple no circulante para vegetales

El presente documento es una traducción de la versión original en inglés (http://teca.fao.org/read/8825). El cultivo hidropónico es el método más común de cultivo de plantas agrícolas sin tierra, que incluye el cultivo de plantas sobre un sustrato o en un medio acuoso con raíces desnudas. Los métodos hidropónicos no circulantes, sobre todo, no requieren electricidad ni una bomba. Con el método presentado en este documento, se puede cultivar todo el cultivo con sólo una aplicación inicial de agua y nutrientes. No se necesita agua o fertilizantes adicionales. Normalmente, el cultivo termina cuando la mayor parte de la solución nutritiva esté consumida. Este documento proporciona dos detalladas descripciones paso a paso de kits del cultivo hidropónico simple no circulante para el cultivo de hortalizas a pequeña escala, uno para vegetales de ciclo corto (por ejemplo, lechuga o kai choy) y otro para hortalizas de ciclo largo (por ejemplo, pepino o tomate).

Construction of a non-recirculation hydroponic unit for commercial lettuce production

Hydroponics is the most common method of soil-less culture (growing agricultural plants without the use of soil), which includes growing plants either on a substrate or in an aqueous medium with bare roots. Non-circulating hydroponic methods, importantly, do not require electricity or a pump. With the method presented in this document, the entire crop can be grown with only an initial application of water and nutrients. No additional water or fertilizer are needed. The crop is usually terminated when most of the nutrient solution is consumed. This document provides a detailed description of the construction of the growbeds and grow sheets used in the non-circulating hydroponic unit for commercial lettuce production.

Managing a non-recirculation hydroponic unit for commercial lettuce production

Hydroponics is the most common method of soil-less culture (growing agricultural plants without the use of soil), which includes growing plants either on a substrate or in an aqueous medium with bare roots. Non-circulating hydroponic methods, importantly, do not require electricity or a pump. With the method presented in this document, the entire crop can be grown with only an initial application of water and nutrients. No additional water or fertilizer are needed. The crop is normally terminated when most of the nutrient solution is consumed. This document provides a detailed description of how to fill and manage the non-circulating hydroponic unit for commercial lettuce production including the application of fertilizers, the seeding, transplanting, growing and harvesting.

Simple non-circulating hydroponic method for vegetables

With the method presented in this document, the entire crop can be grown with only an initial application of water and nutrients. No additional water or fertilizer are needed. The crop is normally terminated when most of the nutrient solution is consumed.
This document provides two detailed step-by-step description of simple, non-circulating hydroponic growing kits for growing vegetables at a small scale, one for short term vegetables (e.g. lettuce or kai choy) and the other for long-term vegetables (e.g. cucumber or tomato).
