Análisis del balance hídrico en rodales naturales entre dos especies de bambú en la parroquia Sevilla provincia de Morona Santiago.

Abstract

In Ecuador, there are 47 species of bamboo of which there is no information on its water balance, which is essential for the development of plants; however, natural resources are reaching their limit by anthropogenic activities affecting the air, water, soil, Therefore, the aim of this research was to analyze the water balance in natural stands between two species of bamboo Guadua angustifolia and Phyllostachys aurea in the parish of Sevilla Don Bosco, in Morona Santiago province. The methodology implemented had a mixed approach, exploratory and descriptive type, with an experimental design of transversal type since there is manipulation of variables and it was developed in a diurnal period of time trying to maintain the same atmospheric conditions in order to reduce accidental errors. The population under study were the bamboo species located in the Arrayan and Piedra Farm, being the type of field and documentary study necessary to obtain data and information through different methods-techniques and instruments such as: Thornthwaite method, Theoretical Storage, the Davis meteorological station, and so on. By means of this methodology it was possible to analyze the water balance among the species where Bamboo phyllostachys aurea (b) has a water storage capacity of 96%, Guadua angustifolia with 90.13% and grass with 56.81% (a) with differences between them, concluding that the B.phyllostachys contains the highest water storage capacity by the two methods, proving that bamboo is an excellent erosion controller and soil rehabilitation, in addition to avoiding fragments of impurities in rivers.
