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,施用活化腐植酸缓释肥的花生长势、经济性状和产量均优于其他处理,其中活化腐植酸缓释肥增产效果最显著,每亩增产20.4%。果仁中蛋白质含量增加0.96%～1.79%,脂肪含量增加1.68%～4.66%;氮磷钾利用率分别提高29.54%～67.71%,14.61%～34.55%和5.98%～23.85%。本试验以活化腐植酸缓释肥肥效最好。
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 growth potential, economic characters and yield of activated humic acid sustained-release fertilizer were better than those of other treatments. The activated sludge humic acid slow-release fertilizer had the most obvious yield increase of 20.4% per mu. The content of protein in nuts increased by 0.96% -1.79% and the content of fat increased by 1.68% -4.66%. The utilization of NPK increased by 29.54% -67.71%, 14.61% -34.55% and 5.98% -23.85% respectively. The test to activate humic acid slow release fertilizer fertilizer best.
