\u00a0 \u00a0 \u00a0 \u00a0 En vingt ans de pratique de l'ing\u00e9nierie des \u00e9tangs \u00e0 poissons, nous avons r\u00e9alis\u00e9 qu'un plan d'eau ornemental sain est essentiellement un contrat pr\u00e9cis entre les micro-organismes, les organismes aquatiques et l'environnement physique. En combinant les normes d'\u00e9levage de la Japanese Koi Association (JKIA), les derniers r\u00e9sultats de l'Institut allemand de m\u00e9canique des fluides et de l'Institut de biologie aquatique de l'Acad\u00e9mie chinoise des sciences, nous avons d\u00e9compos\u00e9 le processus apparemment obscur de la \"culture de l'eau\" en 36 n\u0153uds techniques quantifiables. En particulier, les r\u00e9sidus alcalins des piscines en b\u00e9ton, l'\"effet de court-circuit\" des syst\u00e8mes de filtration et l'inactivation \u00e0 basse temp\u00e9rature des bact\u00e9ries nitrifiantes sont les trois facteurs invisibles les plus facilement n\u00e9glig\u00e9s par les novices. Cette \u00e9dition du manuel comprend un nouveau module sur l'analyse des donn\u00e9es (big data) bas\u00e9 sur 200 cas de projets, qui vous aide \u00e0 anticiper des solutions de traitement sp\u00e9ciales pour diff\u00e9rentes zones climatiques (par exemple, les sols acides du sud de la Chine par rapport aux sols salins et alcalins du nord-ouest de la Chine).<\/span><\/p>\n
