草莓栽培农事成本分析数据

农事活动记录作为农业生产管理的核心环节，全面记载了农作物从播种前准备到收获贮藏的全周期操作，包括土壤处理、水肥管理、病虫害防治、植株调整及采收等关键农事操作。本数据集详细记录了长三角地区温室无土栽培草莓的生长季的实操数据，结合水肥一体化系统特性，为同类种植者提供了可复用的技术参考。通过精准分析不同生长阶段（季初准备、定植期、花果期、采收期、季末清园）的人工成本构成，种植者可据此预判单季人工费用，优化资源分配，规避技术失误风险，有效控制因操作不当导致的减产或成本超支。
一、数据采集
1.数据来源：从农事操作记录表中提取原始字段（日期、用工人数、工作时长、总工时、单价、金额等）。
2.对关键特征进行补充分类：生长阶段标注（季初/定植期/花果期/采收期/季末），农事大类归类（植株管理/收获/栽培管理/植保工作/清园/种前准备）以及具体农事工作。
二、数据预处理
对采集的数据进行清洗，去除重复记录，处理缺失值
三、数据处理
1.计算总成本= ∑(所有记录的金额字段值)
2、计算各阶段成本：花果期植株管理成本 = ∑(生长阶段="花果期" 且 农事大类="植株管理" 的记录金额)
3、计算成本占比：花果期植株管理成本占比 = (花果期植株管理成本 / 总成本) × 100%
其他5类成本同理计算

As a core component of agricultural production management, farm operation records comprehensively document the full-cycle operations of crops from pre-sowing preparation to harvest and storage, including key farming practices such as soil treatment, water and fertilizer management, pest and disease control, plant adjustment, and harvesting. This dataset details the practical operation data of soilless cultivated strawberries in greenhouses across the Yangtze River Delta during their growing seasons, and combines the characteristics of integrated water and fertilizer systems to provide reusable technical references for similar growers. By accurately analyzing the composition of labor costs across different growth stages (pre-season preparation, planting stage, flowering and fruiting stage, harvesting stage, and end-season garden cleaning), growers can predict single-season labor costs, optimize resource allocation, avoid technical error risks, and effectively mitigate yield losses or cost overruns caused by improper operations.

I. Data Collection
1. Data Source: Extract original fields (date, number of workers, working hours, total man-hours, unit price, total amount, etc.) from farm operation record sheets.
2. Supplementary classification of key features: Label growth stages (pre-season / planting stage / flowering and fruiting stage / harvesting stage / end-season), categorize farm operations into major types (plant management / harvesting / cultivation management / plant protection / garden cleaning / pre-sowing preparation) along with specific farming tasks.

II. Data Preprocessing
Clean the collected data, remove duplicate records, and handle missing values.

III. Data Processing
1. Calculate total cost = ∑(amount field values of all records)
2. Calculate stage-specific costs: Cost of plant management during flowering and fruiting stage = ∑(amount of records where growth stage = "flowering and fruiting stage" and farm operation category = "plant management")
3. Calculate cost proportion: Proportion of plant management cost during flowering and fruiting stage = (Cost of plant management during flowering and fruiting stage / Total cost) × 100%. The other five types of costs are calculated in the same manner.
