为了指导水稻生产合理施肥,采用田间小区试验,研究了氮、磷、钾、硅锰、有机肥配合施用对水稻养分迁移、光合特性、籽粒产量及蛋白质含量的影响.结果表明:氮、磷、钾、硅锰、有机肥配合施用能促进水稻氮、磷、钾的吸收、转运、累积,提高籽粒氮、磷、钾含量及籽粒粗蛋白质含量;氮、磷、钾、硅锰、有机肥配合施用对水稻产量的形成有明显的促进作用,主要是通过提高功能叶的净光合速率、有效穗、每穗实粒数来实现.

Effects of combined fertilization of nitrogenous fertilizer(N),phosphate fertilizer(P),potash fertilizer(K),silicon fertilizer(Si),manganese fertilizer(Mn)and organic fertilizer on migration of nutrients,photosynthesis characteristic,yield and grain protein contents in brown rice were investigated in field-plot experiment.The results show that by means of raising net photosynthesis ratio of functional leaves,effective ears and seeds per ear.Proper application of N-P-K-Si-Mn-organic combined fertilizer can Ⅰ. promote absorption,transportation a...
