Performance do crescimento de mudas em diferentes estratégias de manejo como uma ação para recomposição e diversidade biológica de um ambiente em regeneração

Abstract

In regions with a semi-arid climate, abiotic (ie, low rainfall, high incidence of factors, shallow and saline soils, nutritional deficit, etc.) recomposition of degraded areas, in addition to contributing to the increase of the biosphere and atmosphere. Currently, they cite the restoration of important work in process, using different management strategies. The adoption of practices aimed at restoring the environment becomes essential for maintaining environmental balance. Based on this, we analyzed the aspects of the effects of different management techniques on the biometrics of seedlings of five species, Anadenanthera colubrina (Angico branco), Cratylia argentea, (Camaratuba), Libidibia ferrea, (Pau ferro), Handroanthus impetiginosus (ipê – purple) ) and Sesbania bispinosa. The work is subdivided into two chapters: 1) Bibliographic review which was highlighted as the main adaptive strategies of plants of the bio caatinga format, as well as the use of different strategies used to recompose anthropized areas, and scientific 2) no. it comes from an experiment that sought to analyze the biometry and survival of the fauna of the caatinga in scientific initiation, with the purpose of enriching an area in a working state, aiming at the diversity of this environment. Therefore, an experiment was carried out between December 2021 and May 2022, at the Academic Unit of Serra Talhada (UAST/UFRPE). Seedlings of five species: Anadenanthera colubrina (Angico white). Cratylia argen, (Camaratuba)bidtea ferrea, Handroanthus impetiginosus (pei – purple) and Sesbania bispinosa were subjected to different management strategies: T1 = Control, T2= soil + hydrogel, T3= compost and T4= hydrogel + compost in an area of Caatinga in design. In average intervals of 8 days, the biometric knowledge parameters of the species were created: Height of the plant diameter (DC, mm), count of the number of leaves (NF) and the average of the canopy area (AC) ) (North - South; East - West). Data were selected for analysis of variance and comparison of means was performed using Tukey's test at a 5% probability level. What use of the hydrogel, organic compound + organic compound, we did not account for the variables among the variables. In this, the land use only aspect considered for better results and with the creation of low cost systems. The nucleation proved to be efficient for several biologicals in the environment and in this aspect, there was a better growth of angico followed by pau ferro.
