为开发一种适用于东北地区玉米生长的速效加长效的腐殖酸复合肥,将腐殖酸复合肥与脲酶抑制剂(NM)、腐殖酸钾(HAK)、控失剂(KSJ)等3种不同类型的缓释剂复配并开展了田间小区试验。结果表明:腐殖酸复合肥与缓释剂复配,可提高玉米的产量、茎粗、叶片叶绿素相对含量(SPAD值);不同缓释剂之间的效果差异较显著,腐殖酸复合肥与NM或HAK复配的综合效果较好。腐殖酸复合肥与缓释剂复配,可实现东北地区一次施肥满足玉米整个生育周期内对养分的需求。
In order to develop a quick and long-acting humic acid compound fertilizer suitable for maize growth in Northeast China, humic acid compound fertilizer is combined with three different types of slow-release agents such as urease inhibitor (NM), potassium humate (HAK) and loss control agent (KSJ), field experiment is carried out. The results show that the combination of humic acid compound fertilizer and slow-release agent could increase the yield, stem diameter and relative chlorophyll content (SPAD value) of maize. The effects of different slow-release agents are significantly different and the better comprehensive effect is when humic acid compound fertilizer combined with NM or HAK. The combination of humic acid and slow-release agent can realize one-time fertilization in Northeast China and meet the nutrient demand of maize in the whole growth cycle.
