    摘要:

    为研究氮锌配施对水稻生长、产量和养分吸收分配的影响,采用大田小区试验,以籼型杂交稻品种广两优35和常规粳稻品种日本晴为研究材料,设置3个锌水平和4个氮水平的交互处理,分析了各生育期水稻的生物量,成熟期产量及构成因素,各部位氮和锌的含量、累积量和分配比例。结果表明,氮锌配施对水稻早期的生长和后期的产量形成均具有协同增效效应,这种效应在不同水稻品种中具有一定的差异性。氮锌配施对水稻每公顷穗数具有极显著的正向交互效应,每公顷穗数的显著增加是氮锌配施下水稻产量提高的主要原因。氮锌配施不仅提高了水稻植株中的氮和锌含量,同时还促进了氮和锌向生殖器官(小穗)中分配,这可能是水稻产量提高的主要生理机制之一。

    Abstract:

    In order to investigate the effect of the combined application of N and Zn fertilizers on the growth,yield,nutrient absorption and distribution of rice,the indica hybrid rice variety Guangliangyou 35 and conventional japonica rice cultivar Nipponbare were treated with combined application of three Zn levels and four N levels in field experiment. We analyzed the shoot dry weight at different growth stages,the yield and its components at mature stage as well as the concentrations,accumulations and distributions of N and Zn in different organs and tissues. Results showed that the combined application of N and Zn fertilizers had synergistic effect on the rice biomass at the early growth stage and the yield at the mature stage. The combined application of N and Zn fertilizers had significant synergistic effect on rice panicle numbers. The significantly increased panicle numbers determined the increase of yield under the combined application of N and Zn fertilizers. The combined application of N and Zn fertilizers increased the concentrations of N and Zn in rice plant,and promoted the distribution of N and Zn to the reproductive organ (spikelet),which is one of the main physiological mechanisms of increasing yield under the combined application of N and Zn fertilizers.
