余杭区中泰街道高标准农田水稻氮磷钾分析数据

通过监测余杭区中泰街道地区水稻作物土壤中营养元素的含量数据，分析NPK配比数据，用于精准定制科学施肥方案、调整种植结构、监测土壤质量等场景，确保作物获得最佳营养，同时减少成本与环境污染，维持土壤健康；同时可指导作物品种选择与轮作，适应气候变化，提升农业应对环境变化的能力，提高农业生产效率，推动生态保护和经济双赢的农业发展模式。采集了氮、磷、钾土壤化学元素含量数据，分析土壤中N、P、K化学元素占比：
含量变化量=当前时间该元素含量-开始时间该元素含量；
含量预警区间代表了土壤中该元素正常含量的区间，含量正常时预警为0，含量不正常时预警为1。
NPK配比要求指的是N（氮）、P（磷）、K（钾）三种元素在科学计算后得出的该作物成长需要的最合适的占比，NPK实际占比=N含量/P含量：P含量/P含量：K含量/P含量，通过测量得出实际的土壤化学元素含量占比，通过和配比要求进行对比，为今后指导施肥、调整作物结构提供帮助。
通过科学合理地利用氮磷钾含量分析，可以更好地保护土壤资源、提高农业生产效率、促进生态环境的可持续发展。

This dataset is developed by monitoring the concentrations of nutrient elements in rice cropland soil of Zhongtai Subdistrict, Yuhang District, and analyzing the NPK ratio data, which is applied in multiple scenarios including precise formulation of scientific fertilization schemes, adjustment of planting structures, and soil quality monitoring. Its goals are to ensure optimal nutrient supply for crops, reduce costs and environmental pollution, maintain soil health, guide crop variety selection and crop rotation, adapt to climate change, enhance agricultural resilience to environmental changes, improve agricultural production efficiency, and promote an agricultural development model that achieves a win-win outcome for ecological conservation and economic benefits.

The dataset collects the contents of soil chemical elements including nitrogen (N), phosphorus (P) and potassium (K), and analyzes the proportions of these three elements in the soil:
1. Content change = current element content at the measurement time minus the initial element content at the start of monitoring;
2. The content warning interval denotes the normal concentration range of the target element in soil. The warning value is set to 0 when the element content is within the normal range, and 1 when the content is abnormal.

The NPK ratio requirement refers to the optimal proportion of N, P and K required for crop growth derived via scientific calculation. The actual NPK proportion is calculated as (N content / P content) : 1 : (K content / P content) based on the measured soil chemical element contents, normalizing all element contents against the phosphorus content. By comparing the actual proportion with the preset NPK ratio requirement, the dataset provides guidance for future fertilization decisions and crop structure adjustment.

Rational utilization of the analysis results of N, P and K contents can better protect soil resources, improve agricultural production efficiency, and promote the sustainable development of the ecological environment.
