| 摘 要： | 以常规粳稻秀水09和杂交籼稻两优培九、国稻6号为试验材料,在2007和2008年采用大田试验,研究了超微气泡增氧灌溉对水稻生物学特性和产量的影响。结果表明,与常规灌溉相比,增氧灌溉处理具有分蘖发生快,叶面积指数大,干物质积累多等优点,尤其在生育后期表现出较大的干物质积累优势。增氧灌溉显著增加了水稻产量,其中秀水09分别增产8.45%(2007)和6.23%(2008)、国稻6号增产9.13%、两优培九增产7.49%。而且增氧灌溉明显提高了水稻有效穗数及结实率,但对水稻每穗总粒数和千粒重影响不明显。

| Abstract: | With the inbred japonica rice Xiushui 09 and indica hybrid rice Liangyoupeijiu and Guodao 6 as materials,a field experiment was conducted to study the effects of ultramicro bubble aerated irrigation on growth characters and yield of rice in 2007 and 2008.The results indicated that compared with conventional irrigation,ultramicro bubble aerated irrigation increased the tiller growth rate,leaf area index and dry material accumulation,especially enhanced the dry material accumulation during grain filling stage... |
