摘要: 为了探明活性腐殖酸缓释肥对花生生长发育、产量和肥料利用的影响,在黄冈市农业科学院试验基地开展田间小区对比试验。结果表明,活性腐殖酸缓释肥和普通复合肥均可以提高花生植株、果壳和子仁中全氮、全磷的积累量,花生果壳中全氮、全磷、全钾积累量均最低;与普通复合肥相比,活性腐殖酸缓释肥农学利用率更高,可以缩短侧枝长度,花生生长更稳健,通过提高花生的单株结果数、单株饱果数和百果重、百仁重,增产效果更显著;活性腐殖酸缓释肥经济效益高于普通复合肥,施肥量为525 kg/hm2时,花生经济效益增收最多,每公顷达到2 656.79元,肥料贡献率21.92%,农学利用率1.61 kg/kg。

Abstract: In order to understand the effects of activated humic acid slow-release fertilizer on peanut growth, yield and fertilizer utilization, the comparative experiment of field plots in Huanggang Academy of Agricultural Sciences base was carried out. The results showed that the accumulation of total nitrogen and total phosphorus in peanut plants, fruit shells and seed kernels could be increased by both active humic acid slow-release fertilizer and common compound fertilizer. The accumulation of total nitrogen, total phosphorus and total potassium in peanut shells was the lowest. Compared with common compound fertilizer, the agricultural utilization rate of active humic acid slow-release fertilizer was higher, the length of the side branch could be shortened, and peanut growth was more robust. The yield increase was more significant by increasing the number of fruit and full fruit per plant, and the weight of 100 fruit and 100 kernels. The economic benefit of active humic acid slow-release fertilizer was higher than that of common compound fertilizer.With the 525 kg/hm2 fertilizer application rate, peanut economic benefit increased the most, reaching 2 656.79 yuan per hectare. The fertilizer contribution rate was 21.92%, and the agricultural utilization rate was 1.61 kg/kg.

Key words: peanut, active humic acid slow-release fertilizer, economic benefits
