摘　　要：为考察黑力旺含腐殖酸液体肥料对促进水稻返青分蘖的效果,以市售等养分含量的含腐殖酸液体肥料为对照,开展了盆栽试验。结果表明:在等追肥量的条件下,追施黑力旺含腐殖酸液体肥料后第35天的水稻叶片叶绿素相对含量(SPAD值)、分蘖数、地上部鲜质量均显著优于追施对照肥料的;在追施黑力旺含腐殖酸液体肥料不同量的条件下,第35天各处理的SPAD值、分蘖数、地下部鲜质量随追肥量的增加呈先升后降的趋势,且处理间无显著性差异,但地上部鲜质量呈现一定的差异性。追施黑力旺含腐殖酸液体肥料能增强水稻的返青能力,增加了有效分蘖数,提高了植株的生物量,追施0.8 g/盆黑力旺含腐殖酸液体肥料的效果较理想。In order to investigate the effect of Heiliwang liquid fertilizer containing humic acid on promoting rice regreening and tillering,a pot experiment is conducted using commercially available liquid fertilizer containing humic acid with equal nutrient content as a control.The results show that under the condition of equal topdressing amount,the relative chlorophyll content(SPAD value)of rice leaves,tiller number,aboveground fresh weight on the 35th day after topdressing with Heiliwang liquid fertilizer containing humic acid are significantly better than those of the control fertilizer.Under the conditions of applying different amounts of Heiliwang liquid fertilizer containing humic acid,the SPAD value,tiller number,and underground fresh weight of each treatment have a trend of first increasing and then decreasing with the increase of topdressing amount on the 35th day.There is no significant difference between the treatments,but there is a certain difference in aboveground fresh weight.Topdressing with Heiliwang liquid fertilizer containing humic acid can enhance the ability of rice regreening,increase effective tillering numbers,and increase plant biomass.The effect of topdressing with 0.8 g/pot of Heiliwang liquid fertilizer containing humic acid is ideal.
