- 摘要:
- 为研究生化黄腐酸钾对作物生长的影响,以玉米郑单958为研究对象,探究不同生化黄腐酸钾含量的肥料对玉米根系、茎秆及生物产量的影响。结果表明,在肥料中添加5.0~8.0 kg·t-1的生化黄腐酸钾,能够显著促进玉米根系、茎秆生长以及生殖生长。在添加量为8.0 kg·t-1条件下,肥料增效效果最为显著和稳定,与普通对照相比,能够将玉米根系鲜重提高35.3%,使玉米生物量显著提高12.3%,使玉米生长期茎粗提高50%~21.7%。说明添加8.0 kg·t-1生化黄腐酸钾的肥料能够促进玉米生长,因此可作为提质增效肥料用于玉米生产。
- Abstract:
- In order to study the effects of biochemical fulvic acid potassium on crop growth, maize Zhengdan 958 was taken as the research object to explore the effects of fertilizers with different biochemical fulvic acid potassium contents on maize root, stem and biomass. The results showed that adding 5.0-8.0 kg·t-1 biochemical fulvic acid potassium to the fertilizer could significantly promote the growth of root, stem and reproduction of maize. Under the condition of adding 8.0 kg·t-1, the effect of fertilizer was the most significant and stable. Compared with the fertilizers common control, it increased the fresh weight of maize roots by 35.3%, significantly increased the biomass of maize by 12.3%, and increased the stem diameter of maize during the growth period by 5.0%-21.7%.In conclusion the fertilizer added with 8 kg·t-1 biochemical fulvic acid potassium can promote the growth of maize, so it can be used as a quality improling fertilizer for specific maize production.
