以杂交晚稻岳优518和常规晚稻湘晚籼12号为试验材料,设置土壤表层10 cm稻壳炭体积含量为 A (0)、B(0.25%)、C(0.5%)、D(1%)、E(2%)和 F(4%)处理,研究稻壳炭对水稻产量、茎秆和稻米矿质元素含量的影响。结果表明：随着土壤稻壳炭施入量的增加植株茎秆中的硅、钾元素含量增加。 F处理的岳优518茎秆中的硅元素含量和钾元素含量分别比对照增加41.18%和51.44%,F处理的湘晚籼12号茎秆中的硅元素含量和钾元素含量分别比对照增加69.47%和60.69%。随着土壤稻壳炭含量的增加,不同生育期叶片净光合速率、稻谷每667 m2平均产量也增加。 F处理的岳优518增产12.34%,F处理的湘晚籼12号增产13.12%；稻壳炭提高岳优518的每穗粒数、每穗实粒数和结实率。稻壳炭增加稻米矿质元素磷、钙、镁、钾、锌、硫、铜、锰和铁含量。

In order to study the effect of rice husk charcoal on the yield and mineral element content of stem and rice, hybrid rice Yueyou 518 and conventional rice Xiangwanxian 12 were used experimental materials, we set up the rice husk charcoal and 10 cm deep surface soil volume percentage treatments of A(0), B (0. 25%), C(0. 5%), D (1%), E(2%) and F(4%). The results showed that silicon and potassium content of plant stem increased as the soil volume percentage of rice husk charcoal increased. The content of silicon and potassium increased 41. 18% and 69. 47% in treatment F than those in control of Yueyou 518 stem and Xiangwanxian 12 stem, respectively. Silicon and po-tassium content were increased 51. 44% and 60. 69% in treatment F than those in control of Yueyou 518 stem and Xian-gwanxian 12 stem, respectively. The leaf net photosynthetic rate at different development stage and average yield per 667 m2 increased as the soil volume percentage of rice husk charcoal increased. The average yield per 667 m2 increased 12.34% in treatment F than that in control of Yueyou 518. The average yield per 667 m2 was increased 13. 12% in treat-ment F than that in control of Xiangwanxian 12. The rice husk charcoal increased grain number per panicle, filled grain number per panicle and setting percentage in Yueyou 518. The rice husk charcoal increased the rice essential element contents of phosphorus, calcium, magnesium, potassium, zinc, sulfur,copper, manganese and ferrum.
