为探究土壤生态治理与化肥减量技术,实现夏玉米优质高产稳产和节本增效,通过田间试验研究喷施炭吸附聚谷氨酸有机水溶肥对夏玉米产量、经济效益的影响。河南省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,能提高肥料利用率,增强抗逆能力,表现根系发达、茎秆粗壮、不旱衰,能有效提高玉米的穗粒数和千粒重。在70%常规化肥施量条件下,增产5.3%,增效55.72元/亩。
In order to explore the techniques of soil ecological management and chemical fertilizers reduction, to achieve high quality, high yield, stable yield and cost efficiency of summer maize, the effect of spray spraying polyglutamic acid organic water soluble fertilizer on yield and economic benefits of summer maize was studied through field experiments. The results from the pilot sites in Shangshui County, Henan Province showed that the application of carbon-adsorbed polyglutamic acid organic water-soluble fertilizer on the 6th to the 9th leaf stage of summer maize can improve the utilization rate of fertilizers and enhance the resistance to stress. The results show that the roots are developed, the stalks are stout, Not bad drought, can effectively improve the number of grains per spike and 1000-grain weight. Under the condition of 70% conventional fertilizer application, the yield increase was 5.3% and the profit increase was 55.72 yuan / mu.
