不同类型腐植酸配合优化施肥对小麦-玉米轮作体系产量及构成的影响
Effects of combined application of different types of humic acid with optimized fertilization on yield and its components in a wheat-maize rotation system
摘要
Abstract
To investigate the synergistic regulatory effects of different types of humic acid combined with optimized fertilization on crop yield,a fixed-site field experiment with a winter wheat(Triticum aestivum L.)-summer maize(Zea mays L.)rotation was conducted from 2022 to 2024 in the fluvo-aquic soil area of Xinxiang County,Henan Province.Five treatments were established,including con-ventional fertilization(T1),optimized fertilization(T2),and optimized fertilization combined with micro-activated humic acid(T3),humic acid organic material(T4),or potassium humate(T5),respectively.The results showed that wheat yield over the two years was higher under the T3 and T4 treatments than under other treatments,while maize yield was higher under the T5 treatment.The two-year average results indicated that the T3 and T4 treatments were most effective in increasing wheat spike number.The T5 treatment re-sulted in higher maize kernel number per ear and 1000-kernel weight compared to other treatments,showing stable and optimal perfor-mance.High yield in wheat mainly relied on the increase in spike number,whereas achieving high yield in maize required the synergis-tic optimization of key traits such as ear number,kernels per row,and ear length,indicating differences in yield formation mecha-nisms between the two crops.In conclusion,the combined application of optimized fertilization with humic acid synergistically achieved fertilizer reduction along with increased yield and efficiency.The optimal combination for wheat was optimized fertilization with micro-activated humic acid or humic acid organic material,while for maize,it was optimized fertilization with potassium humate.关键词
