水稻病虫害类型预测数据

水稻作为全球主要粮食作物之一，其病虫害管理对保障粮食安全至关重要。利用现代信息技术预测水稻病虫害类型不仅能提前采取防治措施，还可以减少农药使用，保护环境。该模型解决了水稻生长状况与病虫害之间的关系。通过理化实验以及调查获取水稻的数据,首先进行数据预处理，包括数据清洗和特征选择，然后对数据进行标准化。通过输入种植密度(株/亩),发病率(%),叶片颜色指数(SPAD),株高(cm),穗长(cm),分蘖数,生育期(天),抗病评分到支持向量机模型中, 通过调整参数如正则化系数C和核函数参数来优化模型，使用交叉验证确保模型的泛化能力。最终，模型被用来预测新数据的病虫害类型，帮助制定防治策略。As one of the world's primary staple food crops, rice pest and disease management is critical for safeguarding global food security. Predicting rice pest and disease types using modern information technology can not only enable early implementation of control measures but also reduce pesticide usage and protect the ecological environment. This model elucidates the correlation between rice growth status and pest/disease infestations. Rice-related data is collected through physicochemical experiments and field surveys. Initially, data preprocessing is conducted, including data cleaning and feature selection, followed by data standardization. Input features such as planting density (plants/mu), disease incidence rate (%), SPAD leaf color index, plant height (cm), panicle length (cm), tiller number, growth period (days), and disease resistance score are fed into the Support Vector Machine (SVM) model. The model is optimized by tuning parameters including the regularization coefficient C and kernel function parameters, and cross-validation is applied to ensure the model's generalization capability. Ultimately, the trained model is used to predict the pest and disease types of new datasets, aiding in the formulation of targeted pest and disease control strategies.
