叶片光合性能是作物产量形成的物质基础与决定因素。为了明确南荻炭基土壤调理剂施用后的水稻增产效应,采用盆栽试验,以籼型两系杂交稻‘深两优5814'为试验材料,探究SC1、SC2、SC3三种不同配方的南荻炭基土壤调理剂施用对水稻抽穗日期、叶片光合性能及产量的影响。结果表明: ①南荻炭基土壤调理剂施用后,水稻抽穗日期提前4~ 12 d,达显著促进效应,其中土壤调理剂SC3促进效应最佳; ②与CK相比,土壤调理剂施用后水稻P_n显著提升22.8%~ 62.4%,其中土壤调理剂SC2的增效作用最显著。此外,土壤调理剂SC1施用后可显著提高水稻叶片G_s、C_i和T_r,较CK分别提高57.0%、8.2%和18.2%; ③水稻叶片中与光合作用...

Leaf photosynthetic charateristics are material basis and determinants of crop yield formation. In order to explore the effects of applying M. lutarioriparius-derived biochar soil conditioner on rice yield-increasing,this paper conducted pot cultivation experiment;took indica two-line hybrid rice "Shenliangyou 5814"as test material;and studied the effects of applying Miscanthus lutarioriparius-derived biochar soil conditioners of 3 different treatments SC1,SC2,SC3 on rice heading date,leaf photosynthetic property and rice yield. Results showed ...
