&lt;p&gt;The role of turbulence is one of key issues for understanding the magnetic and plasma energy conversion, plasma heating and high energy particles acceleration in large temporal-spatial scale turbulent magnetic reconnection (LTSTMR; observed current sheet thickness to characteristic electron length, Larmor radius for low-beta and electron inertial length for high-beta, ratios on the order of ten to the power of ten or higher; observed evolution time to electron cyclotron time ratios on the order of ten to the power of ten or higher) . Solar atmosphere activities (e.g., limbs, flares, coronal mass ejections, solar winds and so on), which are the most important phenomenon in the solar and Sun-Earth space systems, are typical LTSTMRs.&lt;/p&gt;&lt;p&gt;Here we&amp;#160;used our newly developed RHPIC-LBM algorithm[*] &amp;#160;to perform the role of&amp;#160;&amp;#160;turbulence in the magnetic fluctuation-induced self-generating-organization&amp;#160; (MF-ISGO), the turbulence in the plasma turbulence-induced self-feeding-sustaining (PT-ISFS), and the interaction of turbulence between MF-ISGO and PT-ISFS in the continuous kinetic-dynamic-hydro fully coupled LTSTMR.&amp;#160;&lt;/p&gt;&lt;p&gt;First, we find that the self-generated turbulence by magnetic field and plasma motion collective interaction include two fully coupled processes of 1) fluid vortex induced magnetic reconnection (MR) and 2) MR induced fluid vortex.&amp;#160;The Biermann battery effect and&amp;#160;&amp;#160;alpha-effect can not only generate magnetic fields, but can server them to trigger MR, the Spitzer resistance and turbulence resistance (beta-effect)&amp;#160;&amp;#160;can not only generate magnetic eddies, but can server&amp;#160;&amp;#160;them to trigger fluid turbulence.&amp;#160;&amp;#160;&lt;/p&gt;&lt;p&gt;Then, we find that these interaction leads to vortex splitting and phase separating instabilities, and there are four species instabilities coexist in the evolution process. 1) Vortex separation interface instabilities. 2)Magnetic fluctuation-induced self-generating-organization instabilities. 3) Plasma turbulence-induced self-feeding-sustaining instabilities. 4) Vortex shedding instabilities.&lt;/p&gt;&lt;p&gt;Finally, the nuanced details of the magnetic topological structure and the topological characterization of flow structures in plasma of the simulated 3D LTSTMR are also presented.&lt;/p&gt;&lt;p&gt;The characterization of turbulence anisotropy and the turbulence acceleration of the LTSTMR are presented in Part II and Part III of this three-paper series study.&lt;/p&gt;&lt;p&gt;*Techniques and algorithms for RHPIC-LBM have been developed in previous studies (e.g.,Zhu2020a, Zhu2020b)&lt;/p&gt;&lt;p&gt;References&lt;/p&gt;&lt;p&gt;Zhu, B.
