紫花苜蓿绿肥对水稻产量和土壤肥力的影响OA北大核心CSCDCSTPCD
Effects of alfalfa green manure on rice yield and soil fertility
以紫花苜蓿（Medicago sativa）为绿肥植物,利用南方冬闲田种植紫花苜蓿绿肥,研究紫花苜蓿绿肥（茎叶粉碎还田）和氮肥处理对水稻（Oryza sativa）生长、土壤有机质、土壤总氮、土壤速效磷和土壤速效钾含量的影响。结果表明,紫花苜蓿绿肥和紫花苜蓿绿肥＋氮肥处理的水稻产量分别比不施氮肥处理增加了48.2%和72.1%,同时绿肥＋氮肥处理的水稻产量比施氮肥处理增加了8.6%。苜蓿绿肥处理显著提高了土壤有机质、总氮、速效磷和速效钾的含量,改…查看全部>>
A field experiment was carried out to determine the effects of alfalfa green manure and nitrogen fertilizer on rice yield, soil organic matter, soil nitrogen, soil available P and soil available K by planting alfalfa as green manure into winter fallow fields in the south region of China. The results of this study showed that the rice yield in the alfalfa manure treatment and alfalfa manure＋nitrogen treatment increased by 48. 2% and 72. 1%, respectively. Alfa…查看全部>>
