海藻酸尿素不同配比对玉米农艺性状及产量影响研究OA
Effects of Different Ratios of Alginate Urea on the Agronomic Characteristics and Yield of Corn
为研究海藻酸作为肥料增效剂与尿素结合对尿素利用效率的提升效果.以玉米登海605为研究对象,开展普通尿素(CK)、等氮量海藻酸尿素(T1)和减氮量20％海藻酸尿素(T2)肥料田间试验,通过调查研究玉米的株高、茎粗、穗位高及产量相关指标,分析海藻酸尿素对其生长情况的影响.结果表明,海藻酸尿素对玉米植株和产量形成有较好的促进作用,T1处理较CK的玉米株高、茎粗等生物产量增加较多,其中单株秸秆鲜重和干重增加21.9％和17.8％.T2处理较CK处理的玉米产量和籽粒产量均有增加,其中穗鲜重和穗干重分别增加11.6％和9.1％.通过主成分分析,T2即减氮量20％海藻酸尿素对于玉米植株和产量形成效果较好.
To study the effect of alginate as a fertilizer enhancer combined with urea on improving urea utilization efficiency.Field experiments were conducted on corn Denghai 605 using conventional urea(CK),nitrogen equivalent alginate urea(T1),and nitrogen reducing 20％alginate urea(T2)fertilizers.By investigating the plant height,stem diameter,ear height,and yield related indicators of corn,the effects of alginate urea on its growth were analyzed.The research results showed that alginate urea had a good promoting effect on maize plants and yield formation.T1 treatment increased maize plant height,stem thickness,and other biological yields more than CK treatment.Among them,the fresh and dry weight of individual straw increased by 21.9％and 17.8％respectively.The corn yield and grain yield of T2 treatment increased compared to CK treatment,with an increase of 11.6％and 9.1％in ear fresh weight and ear dry weight,respectively.Through principal component analysis,T2,which represents a 20％reduction in nitrogen,has a better effect on maize plants and yield formation.
