| 摘 要： | 在暖温带区的砂土中,对1年内几种常见的有机物料在不同时段的腐解状况进行了研究.结果表明,供试的几种物料总的腐解顺序为:玉米秸秆>小麦秸秆>鸡粪>牛粪>猪粪,秸秆类的腐解速率明显高于粪肥类.各种有机物料在进入土壤后前90 d的分解速率最快,均超过全年总分解量的60%;然后变缓.土壤活性有机质含量在有机物料施入土壤180 d时达最大值,360 d时低于腐解90 d时的含量,活性有机质一般在每年的3~4月份达到最大值;同时腐解过程中土壤有机质和活性有机质二者之间具有显著的相关性.

| Abstract: | The decomposition laws of organic matters(O.M.) were studied by nylon-bag experiment within a year in warm-temperate zone area.The research results showed that the decomposition sequence of used organic matters was maize straw >wheat straw >chicken manure >cow manure >pig manure.The decomposition rate of straws was obviously higher than that of manures.Organic materials were decomposed fastest in the beginning 90 days after entering the soil,exceeding 60% of the total amount of the whole year decomposition,and then the decomposition rate becomes slow.During different stage of the year,the content of liable organic matter(CLOM) reached the maximum on 180 days of O.M.decomposition.The CLOM of 360 days was lower than that of 90 days.CLOM generally reaches the maximum in March and April.And both organic matter and CLOM had the remarkable correlation during the decomposition. |
