摘要: 本研究以‘南粳9108’水稻品种为试验材料,探讨了常规施肥与侧深减氮施肥方式下,分别设置喷施硅肥、锌肥、硅+锌肥、对照4个处理,分析研究不同处理下水稻茎蘖数、茎秆物理特性、抗倒能力以及产量表现差异性,以期探明侧深减氮施肥与硅、锌肥协同作用对水稻产量以及抗逆性的影响。结果表明:(1)与常规施肥方式相比,侧深减氮施肥方式能够促进水稻分蘖、增加有效穗数、提高产量,促进茎秆粗壮,抗倒能力显著高于常规施肥方式。(2)侧深减氮施肥方式喷施硅肥的处理基部节间最短、抗折力最大、倒伏系数最低;侧深减氮施肥喷施硅+锌肥的处理分蘖能力最强、有效穗数最多、茎秆最粗壮、产量最高。(3)在同种施肥方式下,硅肥和锌肥同施均能有效促进水稻生长,有效穗数均达到最高,但是对水稻的其他性状影响结果较复杂,并不能达到叠加效果。

Abstract:

To investigate the synergistic effect of side deep nitrogen reduction fertilization and silicon plus zinc fertilizer on the yield and the lodging resistance of rice, traditional fertilization and side deep nitrogen reduction fertilization were carried out using ‘South japonica 9108’ as material, with four treatments including silicon fertilizer, zinc fertilizer, silicon plus zinc fertilizer and no fertilizer, respectively. The number of stems and tillers, the physical characteristics of culm, the lodging resistance, the yield were studied under different treatments. The results showed that: (1) compared with traditional fertilization, side deep nitrogen reduction fertilization could increase the number of stems and tillers, the number of effective panicle, the yield, the stem width, and enhance the lodging resistance significantly. (2) Applying side deep nitrogen reduction fertilization with silicon fertilizer could reduce the basal inter node length, enhance the bending resistance and reduce the lodging coefficient; applying side deep nitrogen reduction fertilization with silicon plus zinc fertilizer had the best tillering ability, the most big number of effective panicle, the strongest culm and the highest yield. (3) Under fertilization methods, applying silicon plus zinc fertilizer could promote the growth of rice effectively, and reach the biggest number of effective panicle, but the effect of other traits on rice was more complicated, the superposition effect could not be achieved.
