海藻酸尿素不同配比对玉米农艺性状及产量影响研究
Effects of Different Ratios of Alginate Urea on the Agronomic Characteristics and Yield of Corn
摘要
Abstract
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.关键词
