摘要
与短期监测相比,高质量的长期观测数据较为宝贵,反映的是环境演变过程或人类活动的长期影响。建立于1981年的双季稻田长期施肥定位试验,为长期观测早晚稻产量及生育期的动态变化提供了很好的条件,本数据集来源于该试验单施氮肥(N)、单施磷肥(P)、单施钾肥(K)、施氮磷肥(NP)、施氮钾肥(NK)、施氮磷钾肥(NPK)、两倍氮磷钾肥、化肥有机肥(早稻紫云英,晚稻猪粪)配施(NPKM)与不施肥(CK)等9个施肥处理早、晚稻的产量,播种期、移栽期、始穗期、成熟期的具体时间及生育期天数的监测数据,时间覆盖1981–2020年,由不同时间的不同人员按照统一的管理方法对数据进行调查、记录、输入、核实、保存与审核所形成的,并包含有完整的样地背景信息和数据观测方法的相对完整和准确的一套数据。本数据集可以为红壤区双季稻田连续施入化肥下水稻生长发育的演变趋势提供资料,也为该地区水稻的科学施肥与高产管理提供精准数据支持。
Compared with short-term monitoring,high-quality long-term observation data is more valuable,as they reflect the long-term impact of environmental changes or human activities.Established in 1981,the long-term fertilization positioning experiment of double season rice fields provides an excellent platform for monitoring the dynamic changes in yield and growth periods of early and late rice.This dataset is sourced from monitoring data of 9 fertilization treatments:single application of nitrogen(N),phosphorus(P),potassium(K),nitrogen and phosphorus fertilizer(NP),nitrogen and potassium(NK),nitrogen and phosphorus potassium(NPK),double nitrogen and phosphorus potassium application,combined chemical and organic fertilization(using purple cloud fern for early rice and pig manure for late rice),and nofertilization control(CK).The dataset includes measurements of yield,sowing period,transplanting period,panicle initiation period,maturity period,and growth period durations for both early and late rice.Covering the period 1981–2020,the data were collected,recorded,entered,verified,stored,and reviewed by different personnel over time following a standardized management protocol,and include comprehensive background information of the experimental plots and data collection methods.This dataset provides information on the trends in rice growth and development under continuous application of chemical fertilizers in double cropping rice fields in red soil areas,and offers precise data support for scientific fertilization strategies and high-yield management of rice in the region.
