钱江源开门红干茶得率受天气影响分析数据

干茶得率代表着茶叶生产加工过程中的茶青的损耗情况，影响茶叶的品质，得率越高损耗越小，品质越好，得率评价系统根据天气、茶青等级、茶青和干茶情况，自动得出钱江源开门红茶叶在不同天气情况下的得率变异性及得率指数结果，评估天气对茶叶得率的影响，若得率变异性波动，代表除天气外，种植、加工技术等其他因素对得率影响较大；帮助茶农对比自家茶叶得率，发现自身在种植、加工过程中可能存在的问题，优化种植技术；科研机构与学术研究者可以利用本数据进行茶叶生产技术和品质控制方面的研究，通过提高种植技术减小天气对茶叶得率的影响；通过大量数据及天气状态，可预测当年茶叶的产量、品质及市场行情，为制定市场营销策略提供参考。1、记录天气、茶青等级、茶青及干茶重量等数据，2、计算得率，得率=茶青/干茶，3、得出统计范围内同一天气且同一茶青等级条件下的最低得率、最高得率、平均得率，4,、得率变异性=|（平均得率-得率）/平均得率|，5、得率指数=（得率-最低得率）/（最高得率-最低得率），6、根据得率变异性及得率指数来判断得率的情况，当得率变异性小于0.1时判断为稳定，反之为波动；当得率指数大于0.4时，判断为高得率，反之为低得率。

Dry tea yield rate represents the loss of fresh tea leaves during tea production and processing, and directly affects tea quality: a higher yield rate corresponds to less processing loss and better tea quality. The yield rate evaluation system automatically generates the yield variability and yield index results of Qianjiangyuan Kaihongmen tea under different weather conditions based on weather data, fresh tea leaf grades, and the weights of fresh and dry tea leaves, so as to assess the impact of weather on tea yield rate. If the yield variability fluctuates, it indicates that factors other than weather, such as planting and processing technologies, exert a greater influence on the yield rate. This system helps tea farmers compare their own tea yield rates, identify potential problems in their planting and processing workflows, and optimize planting techniques. Research institutions and academic researchers can utilize this dataset to conduct studies on tea production technology and quality control, and reduce the impact of weather on tea yield rate by improving planting technologies. With a large volume of historical data and real-time weather status, the system can predict the annual tea output, quality and market trends, providing references for formulating marketing strategies.

The specific data processing steps are as follows:
1. Collect relevant data including weather conditions, fresh tea leaf grades, and the weights of fresh and dry tea leaves;
2. Calculate the dry tea yield rate, where yield rate = weight of fresh tea leaves / weight of dry tea leaves;
3. Calculate the minimum, maximum and average yield rates within the statistical scope under the same weather condition and fresh tea leaf grade;
4. Calculate yield variability: |(average yield rate - individual yield rate) / average yield rate|;
5. Calculate yield index: (individual yield rate - minimum yield rate) / (maximum yield rate - minimum yield rate);
6. Evaluate the yield rate status based on the calculated yield variability and yield index: judge the yield as stable when the yield variability is less than 0.1, otherwise it is categorized as fluctuating; judge the yield as high-yield when the yield index is greater than 0.4, otherwise it is categorized as low-yield.
