摘要
试验以大豆为试材,聚丙烯酰胺(PAM)经拌肥施入,在作物生育期不同阶段(苗期、盛花期、鼓粒期、成熟期)进行采样测定大豆株高、根长、叶绿素含量以及产量,用以研究聚丙烯酰胺施加到农田中对作物的生长发育期生理性状和产量的影响。试验结果表明:施用聚丙烯酰胺对大豆各生育期的株高、根长、叶绿素有一定有益影响,对产量也有一定的正向影响,不同浓度间也存在差异性,但统计分析并不显著。结果认为聚丙烯酰胺对大豆生育性状和产量均无有害影响。
The effect of Polyacrylamide application on soybean growth and yield was investigated. The result showed that: polyacrylamide had certain beneficial impacts on plant height, root length and chlorophyll content at each growth stage of soybean, and had certain positive role on yield. Differences were observed among different treatments. PAM had no harmful impacts on soybean's growth character and soil properties.
