摘要
采用田间小区试验,研究了白浆土施用生物硅肥对水稻养分吸收利用的影响。结果表明,白浆土上施用生物硅肥,可以显著提高水稻植株中氮、磷、钾和硅素养分的含量。在白浆土上以生物硅肥施用量450～600 kg/hm2对水稻养分吸收利用效果较明显。
The plot experiment was carried out to study the influence of applying bio - silicon fertilizer on rice nutrient absorption and utilization in albic soil. The results showed that the application of bio - silicon fer- tilizer in albic soil could increase the contents of nitrogen, phosphorus, potassium and silicon in rice plants significantly. The effect of bio - silicon fertilizer to rice nutrient absorption and utilization was obvious under the application amount of 450 - 600 kg/hm^2 in albie soil.
