摘　　要：为了综合评价中国南方施用猪粪肥对稻穗不同部位籽粒磷素积累的影响,本研究在水稻施肥量N 180kg/hm^2,N∶P_2O_5∶K_2O=3∶1∶2.5情况下,比较施用化肥(NPK)、70%化肥配施30%猪粪(F7M3)、50%化肥配施50%猪粪(F5M5)、30%化肥配施70%猪粪(F3M7)的稻穗不同部位籽粒含磷量。结果发现,化肥配施猪粪肥能有效促进水稻产量的增加与稻穗含磷量的下降,但猪粪肥配施与NPK处理的水稻籽粒吸磷量无明显差异;与NPK处理相比,猪粪肥配施可以显著降低一次枝梗与穗上部二次枝梗含磷量,并能有效降低不同穗位的籽粒含磷量。故猪粪肥能有效影响稻穗不同部位的磷含量,猪粪肥资源的合理利用有利于水稻的高产稳产。In order to comprehensively assess the effects of swine manure application on grain P accumulation at different positions of rice spike in south China,four treatments were designed in the experiment,i.e.,mineral N,P and K(NPK),70%chemical fertilizers plus 30%swine manure(F7M3),50%chemical fertilizers plus 50%swine manure(F5M5),and 30%chemical fertilizers plus 70%swine manure(F3M7),the total amount of nitrogen fertilizer applied in rice was 180 kg/hm^2,N∶P2O5∶K2O=3∶1∶2.5.The results showed that rice yield gradually increased and the P content of rice decreased significantly with the increasing proportion of swine manure.However,no significant difference was observed in total P uptake of rice grains between the swine manure and NPK treatments.Organic swine manure effectively reduced the P content in primary branch and in secondary branch from upper parts of spike,the P content of all parts of rice spike was decreased with the increasing of the rate of swine manure.Swine manure can effectively influence P content in different parts of rice,rational utilization of organic fertilizer resources will be beneficial to high and stable yield of rice.
