摘要
人工合成土壤结构改良剂可分为石油化工产品、第三纪矿物产品以及无机物与有机物相结合产品共三类。已有的研究表明,土壤结构改良剂能促进团粒结构的形成,改善土壤理化性状,增加土壤生物活性,提高土壤肥力。应用现代分析技术探明土壤结构改良剂的改良机制,对于土壤结构改良剂的生产和应用具有重要意义。
There are three main types synthetic soil conditioner available,derived from petroleum chemicals,the Tertiary period minerals and organic materials.Many studies have proved that soil conditioner can help to improve soil aggregate,amend soil physical and chemical properties,enhance activity of soil biologicalcommunity,at last,promote soil fertility.Appliced modern analysis technique to detect the machanism of soil condi- tionerhelp to improve quality of soil conditioner.
