在山东潍坊、烟台、临沂3个地区同步开展腐植酸缓释肥在花生上的肥效试验,研究了不同地区活性腐植酸缓释肥对花生生长和产量的影响。结果表明,各地区花生农艺性状、经济性状和产量均以高施肥量的腐植酸缓释肥处理表现最好,肥效随施肥量的增加呈现上升趋势。同等施肥量条件下,腐植酸缓释肥料优于普通掺混肥料。
In Weifang, Shandong, Yantai, Linyi three regions simultaneous implementation of humic acid sustained-release fertilizer fertilizer effect on peanut to study the effect of different regions of active humic acid slow-release fertilizer on peanut growth and yield. The results showed that all the peanut agronomic traits, economic traits and yield of peanut were the best with humic acid sustained-release fertilizer with high fertilization rate. Fertilizer efficiency increased with the increase of fertilizer application rate. The same amount of fertilizer, humic acid slow-release fertilizer is better than the ordinary mixed fertilizer.
