摘要: 为实现河南夏玉米优质高产和节肥增效。田间试验设计三个处理、三次重复,详细记载玉米的生长发育状况和各项生产费用,以试验小区的实产计产,统计分析不同施肥水平的产量与效益,探索化肥减量的技术途径。周口市商水县试验点的结果表明,在夏玉米6~9叶期喷施“炭吸附聚谷氨酸有机水溶肥”,能促进养分的吸收利用,提高肥料利用率,增强抗逆能力。表现茎杆粗壮、根系发达、活杆成熟、减少秃尖、不旱衰,有效提高穗粒数和千粒重,增产增效显著。在常规化肥施用水平下,增产11.9%,增效1325.3元/hm2,在70%常规化肥施量条件下,增产5.3%,增效835.8元/hm2。该研究为周口市在玉米生产上逐步推广化肥减量技术提供依据。

Abstract: This study aims at achieving good quality, high yield, fertilizer saving and benefit increasing of summer maize in Henan Province. A field experiment was designed with three treatments and three repeats. The growth development and production cost were recorded in detail. The real yields of the test plot were used to analyze the yield and benefit of different fertilizer levels, and explore the way of chemical fertilizer reduction. The results showed that during 6-9 leaf stage, spraying“carbon absorbing olyglutamic acid organic water soluble fertilizer”promoted the nutrients absorption and utilization, improved the utilization rate of fertilizer and enhanced the resistance. The maize showed stout stem, well developed root, matured live stem, decreasing bald tip and no dry failure. This fertilizer improved kernels per spike and thousand kernel weight, the production and efficiency increased obviously. Under the conventional fertilizer level, the yield increased by 11.9%, and the benefit increased by 1325.3 yuan/hm2. Under the 70% conventional fertilizer level, the yield increased by 5.3% and the benefit increased by 835.8 yuan/hm2.
