摘 要:稻田施用沼肥 +少量化肥处理水稻前期生长较慢 ,其分蘖数和株高低于单施普通化肥或水稻专用肥处理 ,但后期转色好 ,且每穗实粒数、结实率和千粒重均优于单施普通化肥或水稻专用肥处理 ,而稻谷产量与单施普通化肥相比无明显增产效果 ,比单施水稻专用肥处理减产 4 .6 %。施用沼肥比单施普通化肥和水稻专用肥处理成本分别降低 19.0 %和 4 2 .5 % ,且提高土壤有机质和N、P、K等养分含量 ,改善土壤结构和培肥地力。The rice varieties using biogas manures (BM) and a few chemical fertilizer grow more slowly in the early growing season, but turn to be better in the late growing season, and more filled grains per panicle, higher full grain rate, higher 1000-grain weight can be obtained than those using chemical fertilizer or special fertilizer for rice. However, the yield has no obvious effect of increase than that using chemical fertilizer, and is 4.6% lower than that using fertilizer special for rice. During the whole rice growing season, the costs of using biogas manures are cut down 19.0% and 42.5% than that of using chemical fertilizer and fertilizer special for rice, respectively. Furthermore, cultivating rice with biogas manures can improve the soil physicochemical characters.
