Abstract:
为促进农田养分循环利用和农业生态环境健康,以粳稻品种运2645为供试材料,设计农田施用水葫芦(将晒干水葫芦按4500kghm-2农田施用)和不施用水葫芦处理(对照),施n量为120kghm-2(ln)、240kghm-2(nn),研究其对水稻物质生产与分配的影响.结果表明:1)农田施用水葫芦使水稻移栽~分蘖中期、分蘖中期~拔节期、拔节~抽穗期、抽穗期~穗后20d和穗后20d~成熟期平均分别比对照8.6%、9.8%、12.2%、15.9%和3.1%,使得成熟期生物产量显著增加(+9.0%);2)与干物质生产量相似,水稻平均叶面积指数(lai)和净同化率(nar)对水葫芦处理的响应呈相似的季节性变化趋势,但nar在穗后20d~成熟期有所下降;3)农田施用水葫芦对水稻不同生育时期叶片、茎鞘和稻穗占地上部干重的比例影响不大;4)增加施n量能够明显增加水稻的干物质生产量;水葫芦×n的互作效应对水稻干物质生产与分配无明显影响.5)农田施用水葫芦使水稻生育前、中期干物质生产量增幅较大,对生育后期影响相对较小.图5表3参15
