摘要:

为探索腐植酸钾肥料是否具有改良土壤、促进作物生长、提高作物抗逆性、改善作物品质、保护农业生态环境等功能,本研究以常规玉米专用肥为对照,含腐植酸钾复合肥为处理比较施用后对土壤改良、培肥地力及2个供试玉米品种的生长、生产、品质及种植成本等因素进行分析。结果表明:腐殖酸钾复合肥处理对改良土壤、培肥地力方面要优于常规施肥对照;玉米营养生长期含腐殖酸钾复合肥处理与对照相比能够显著促进玉米植株茎秆增粗,为玉米抗倒伏打下良好基础;玉米生殖生长阶段腐殖酸钾复合肥处理与对照相比对穗重、芯重、单穗粒重及小区产量有极显著的促进作用;品质上对玉米蛋白质含量、淀粉含量、干物质含量及还原糖含量有少量促进作用,但未达到显著差异水平。成本上腐殖酸钾复合肥使玉米增产22.6%,增收3918元/hm2,增收率为29.6%。表明通过施用腐殖酸钾复合肥具有较好的改善土壤,培肥地力,促进玉米增产提质增收的作用,为作物高产和环境友好型施肥方式提供参考。

Abstract:

Potassium humate fertilizer can increase the content of available potassium of soil, which has the functions of improving soil, promoting crop growth, improving crop stress resistance, improving crop quality, protecting agricultural ecological environment and so on. In this study, conventional maize special fertilizer and potassium humate compound fertilizer were used as the control and treatment. After application, the factors such as soil improvement, fertility, growth, production, quality and planting cost were analyzed. The results showed that the treatment was better than control in soil improvement and fertility cultivation. Compared with the control, the treatment of vegetative growth stage could significantly promote the stalk thickening and lay a good foundation for the lodging resistance of maize. The treatment at the reproductive growth stage of maize significantly promoted ear weight, core weight, grain weight per ear and plot yield. The content of protein, starch, dry matter and reducing sugar of maize were improved slightly, but did not reach significant difference level. In terms of cost, potassium humate compound fertilizer increased maize yield by 22.6% and the yield per hectare increased income by 3918 yuan (29.6%). The results demonstrated that the application of potassium humate compound fertilizer had a good effect on improving soil, fertilizing soil capacity, promoting maize yield and quality, and increasing income, providing reference for high-yield crops and environment-friendly fertilization methods.

Key words: potassium humate compound fertilizer, maize, cultivate a fertile soil, improve quality and efficiency
