2018-2019年再生稻收割机碾压实验数据集

试验在福建省三明市尤溪县梅仙镇下保村进行，试验田块地力中等，肥力均匀。头季稻氮肥用量为150 kg/hm2，氮磷钾施用比例为1:0.6:0.7，移栽前2 d深施基肥，移栽后 7 d撒施分蘖肥；再生季总氮肥150 kg/hm2，头季齐穗后15 d施尿素50 kg/hm2作促芽肥，头季稻收割后10 d施尿素100 kg/hm2作壮苗肥。Experiments were conducted in Xiabao Village, Meixian Town, Youxi County, Sanming City, Fujian Province. The experimental plot had moderate soil fertility and uniform nutrient distribution. For the first rice crop, the nitrogen fertilizer application rate was 150 kg/hm², with the N:P₂O₅:K₂O ratio of 1:0.6:0.7. Basal fertilizer was deeply applied 2 days before transplanting, and tillering fertilizer was broadcast 7 days after transplanting. For the ratoon season, the total nitrogen fertilizer application rate was 150 kg/hm²: 50 kg/hm² of urea was applied as bud-promoting fertilizer 15 days after full heading of the first crop, and 100 kg/hm² of urea was applied as seedling-strengthening fertilizer 10 days after harvesting the first rice crop.

背景概述

该数据集是2018-2019年在福建省三明市进行的再生稻收割机碾压实验数据，由福建省农业科学院水稻研究所创建，重点关注杂交稻的再生力鉴定指标和穗茎比。数据集详细记录了头季稻和再生季的施肥管理（如氮肥用量150 kg/hm²和施肥时间），用于评估收割机碾压对再生稻生长和产量的影响，适用于作物科学和农业机械相关研究。
