摘  要:
田间试验结果表明,施用硅肥可明显提高水稻植株体内SiO2含量;除水浸态硅含量高于85mgkg-1的沈阳市苏家屯区的水稻土外,施用硅肥显著能够提高水稻的产量;根据硅肥用量和水稻产量的关系方程,结合施硅各处理水稻植株体内SiO2的含量,供试地区比较合理的硅肥施用量为200kghm-2;施用硅肥能够在一定程度上提高水稻籽粒中粗蛋白的含量。

Water-soluble Si-fertilizer; Fertilization rate; Fertilization method
摘  要:
Field experiment was conducted to investigate water-soluble Si-fertilization technique on rice. The results as follow: water-soluble Si-fertilizer(NaSiO_3)could increase significantly the yield of rice and the SiO_2 content in rice where the SiO_2 content extracted by water of used paddy soils was under 85 mg kg~(-1);basing on functional relations between water-soluble Si-fertilization rate and yield of rice and the SiO_2 content in straw of rice, for paddy soils used for field experiment the rational Si-fertilization rate was 200kg hm~(-2);water-soluble Si-fertilization could increase the crude protein content in grain of rice.
