不同硅肥施入模式对水稻产量及品质的影响

Effects of Different Silicon Fertilizer Application Modes on Yield and Quality of Rice

以优质水稻品种盐丰47为供试材料进行田间试验,采用小区对比方法,研究了硅钙肥(基施)和冲动海藻液硅(喷施)两种不同硅肥施入量对水稻生长发育、产量及品质的影响。结果表明,施用两种硅肥都能使水稻分蘖数增加、提高成穗率、增强抗倒伏及抗病能力,改善稻米品质。在喷施处理中C5处理产量最高为10 893 kg/hm^2,基施处理中C1处理产量最高为10 176 kg/hm^2,分别较对照增产14.3%、4.8%。

A field experiment was conducted to study the effects of calcium silicate fertilizer and impulsive seaweed liquid silicon fertilizer on the growth,yield and quality of rice‘Yanfeng 47’.The results showed that the application of two kinds of silicon fertilizers increased the number of tillers,earring rate,lodging resistance and disease resistance,and improve the quality of rice.The highest yield,10 893 kg/ha,was gotten in C5 spraying treatment,and the second was 10 176 kg/ha in C1 basal treatment,which increased by 14.3%and 4.8%,respectively.
