对腐植酸缓释肥在花生上进行肥效试验,研究不同肥料品种对花生的农艺性状、经济性状和产量的影响。结果表明:等养分条件下,施用经腐脲-硫活化工艺活化后的腐植酸缓释肥,花生长势、经济性状和产量均优于其他处理。各施肥处理较对照均增产,其中活化腐植酸缓释肥增产效果最显著,增产20.4%。
The humic acid sustained-release fertilizer was tested on the peanut fertilizer efficiency to study the effects of different fertilizer varieties on the agronomic characters, economic characters and yield of peanut. The results showed that under the condition of equal nutrients, the humic acid slow-release fertilizer activated by the ureauric acid-sulfur activation process was superior to other treatments on the growth of peanut, economic traits and yield. All fertilization treatments increased compared with the control, of which the activated sludge humic acid slow-release fertilizer yield the most significant effect, an increase of 20.4%.
