褐土区氮磷有机肥配施长期定位试验1992-2021年玉米产量性状数据集
A dataset of maize yield traits from a long-term fixed-site combined nitrogen,phosphorus and organic fertilizer application experiment in the cinnamon soil region(1992-2021)
摘要
Abstract
Long-term fixed-site experiments offer the advantage of overcoming the susceptibility of field trials to natural environmental influences,and the patterns they reveal can provide a reliable and authentic basis for evaluating the long-term ecological effects of tillage practices.A long-term fixed-site experiment on combined nitrogen,phosphorus,and organic manure application was established in 1992,employing an orthogonal design with three factors(nitrogen,phosphorus,and organic manure)and four levels for each.The experiment includes a no-fertilizer control(CK1)and a treatment with organic manure only(N0P0M6)as CK2,comprising 18 fertilization treatments in total.This dataset was formed through the continuous measurement,recording,and preservation of data on maize yield,sowing date,maturity date,maize cultivar,planting method,field management,annual precipitation,and fertilization rates,all conducted following consistent methodologies from 1992 to 2021.It also contains comprehensive site information data from the sampling sites.Through rigorous long-term fixed-site observations,standardized collection protocols,cross-checking of historical data,and stringent outlier detection,this dataset ensures high accuracy,continuity,and comparability.It thus provides a theoretical basis for scientific fertilization of spring maize in cinnamon soil regions.关键词
