白浆土型水稻土施硅肥对水稻产量及品质的影响

Effect of silicon fertilizer application on yield and quality of rice in albic soil

采用田间试验,研究了在白浆土型水稻土上不同硅肥施用量对水稻产量和品质的影响。结果表明,白浆土型水稻土上最佳的硅肥施用量为600 kg/hm^2,增产8.43%。随着施肥量的增加,穗数、穗粒数均表现出增加的趋势,以施用量450-750 kg/hm^2效果较明显。施用硅肥后,稻米的糙米率提高的幅度不大,以600 kg/hm^2处理为最大,比对照高出0.34%,而精米率和整精米率比对照高0.36%和3.37%;垩白度、垩白率均以150 kg/hm^2处理为最小,分别比对照低8.89%和1.91%;胶稠度和蛋白质含量均以450 kg/hm^2处理为最高,分别比对照高3.49%和16%。

Field experiment was carrid out to study the effects of application silicon fertilizer on yield and quality of rice. The resuits showed that the best silicon fertilizer application rate was 600 kg/hm^2 in albic soil, the yield increased 8.43%. With the fertilizer increasing, panicles, ear have shown increasing trend, the silicun volume have more pronounced of 450 - 750 kg/hm^2. Brown rice rate increased marginally, the 600 kg/hm^2 treatment was the most, 0.34% higher than the control, milled rice and head rice rate 0.36% and 3.37% higher than the control. Chalk, the treatment 150 kg/hm^2 was the smallest, lower than the control 8.89% and 1.91%, respectively; gel consistency and protein content were highest with 450 kg/hm^2, respectively, higher 3.49% and 16% compared with control.
