摘  要：
在长期定位试验条件下,研究了稻作制,有机肥用量及地下水位对红壤性水稻土有机磷组分的影响。结果表明,不同稻作制间,土壤有机磷总量以稻-稻-冬绿最高,稻-稻-冬油次之,稻-稻-冬泡最低;不同施肥水平之间,高量有机肥处理的有机磷高于常量有机肥和化肥处理;高地下水位有利于土壤有机磷的累积。土壤有机磷各形态中,活性有机磷和中活性有机磷随着年际的变化逐渐增加,并且冬泡处理的活性有机磷,中活性有机磷和中稳性有机磷在三种稻作制中最低,施用高量有机肥有利于活性有机磷和中稳性有机磷的累积。

摘  要：
A long-term located experiment was carried out to study the effect of rice-based cropping system,organic manure and ground water level on organic phosphorus fractions of paddy soil derived from quarternary red clay.Among 3 rice-based cropping systems,total organic phosphorus content in the treatment of rice-rice-green manure were the highest,those in the treatment of rice-rice-rape came the second,those in the treatment of rice-rice flooded fallow in winter were the lowest.Among 3 applications of organic manure,the soil organic phosphorus content in the treatment with high rate of manure were higher than those in the treatment of normal rate of manure,and those in the treatment of inorganic fertilizer were the lowest.Higher ground water level could increase the organic phosphorus contents in soil.The LOP and MROP contents increased obviously,and among 3 rice-based cropping systems the LOP,MLOP and MROP contents in the treatment of rice-rice flooded fallow in winter were the lowest.High rate of manure could increase the LOP and MLOP contents.
