Uso de lodos residuales Compostados como componente porcentual de sustratos en dos métodos de Propagación de Aliso (alnus glutinosa) en la Provincia de Pichincha, Machachi, periodo 2019-2020.

The purpose of this research project is the reuse of residual sludge and the evaluation of three percentages of substrates in sexual (seed) and asexual (stake) reproduction in the alder species (Alnus glutinosa). Carried out in two stages: the first stage consists of conditioning the waste sludge by means of two methodologies such as forced aeration, which is based on injecting oxygen into the waste sludge taking into account the appropriate parameters such as pH (6 to 8) , temperature (40 to 60 ° C) and humidity (35% to 55%), was carried out in 9 weeks, manual aeration which is based on the turning of the residual sludge, the difference in the 2 methods is the time in which it took to obtain the compost which was 15 weeks. The compost of the first methodology was used since due to time and the fact that the research project has two phases, the waiting time to perform the required comparison was not reached. The second phase consists of the mixture of compost with soil from the place obtaining substrate with three different percentages which allowed us to observe that there were variations in the growth of the species, therefore an analysis of variance and the Tukey test at 5% was performed error where it gives us that in the treatment (a3b2 50% compost + 50% local soil + seed) 20 species germinated, while in the percentages (a1b2 local soil + seed), a total of 11 species germinated , (a2b2 25% compost + 75% local soil + seed), giving a total of 17 germinated species, (a4b2 75% compost + 25% local soil + seed), giving us a total of 9 germinated species. Meanwhile, for the reproduction of the stake it was less recommended since it could be obtained in the results of the total growth of 25 species given that in the treatment (a3b1 50% compost + 50% land of the place + stake), giving us as a result 16 species sprouted, while in the treatment (a4b1 75% compost + 25% local soil + stake), resulting in the growth of 9 species, while in the other treatments no stake sprouted.
