六月茶山青如黛，茶香四溢满筑城

六月茶山青如黛，茶香四溢满筑城。

　　当下正是夏茶生产旺季，开阳县的万亩富硒茶海间，一垄垄茶树随山势蜿蜒绵延，山高云低，满目苍翠。

　　今年入夏后，气温升高，降雨充沛，位于龙岗镇坝子村的贵州省开阳南贡河富硒茶业有限公司6800亩示范基地内，茶叶长势喜人。“茶园的温度和湿度都很好，土壤酸碱度也适宜，就是缺少氮和钾，该施肥了。”公司总经理李景平坐在办公楼监控室里，就对茶园管理作出了精准决策，“大数据很‘聪明’，让我们管理茶园又轻松，效果又好。”

　　郁郁葱葱的茶树间，耸立着一根根高高的杆子，上面安装的摄像头就像一只只“眼睛”，时时刻刻观察着茶叶的长势和茶园的情形；而茶树顶的一个个白色“小房子”里，传感器实时收集着温度、湿度、酸碱度等信息。在监控室，这些信息通过计算、分析，便能为茶园管理提供数据支撑。

　　“大数据可以让我们对症下药，有针对性地施肥，提前预判防控病虫害等，节省了很多人力物力财力。”李景平说，这几年，公司的茶叶产量每年都稳步提升10%左右。

　　为保证茶叶品质，南贡河茶业公司还通过追溯系统对茶叶进行农残检测。如今，开阳富硒茶已成为贵州“干净茶”的一张名片。

　　“虽然今年受了雹灾，我们也生产了上万斤名优茶。夏茶预计可以采收10万斤。”李景平说。

　　以“公司+基地+合作社+农户”的模式发展，南贡河茶业公司还带动当地村民种植了2000多亩茶叶，为农户特别是贫困户提供务工岗位，优先收购他们的茶青。如今，坝子村落一、落二组的村民全都种上了茶叶，人均年收入超过2万元。

　　自古黔中出好茶。贵阳高海拔、低纬度、多云雾、无污染、山地丘陵交错，是茶叶种植的最适宜区域。目前，全市茶园面积达28万亩，投产茶园23万亩。“近年来，贵阳市培育壮大了一批茶叶龙头企业，目前已有茶叶生产企业、合作社139家，形成了大中小并举的茶叶加工集群，其中不少茶企利用大数据技术与智能装备，推动传统的加工向机械化、标准化、清洁化、智能化方向发展。”贵阳市茶办主任、研究员龚静说。

　　当前，已有十余家茶企像南贡河茶业公司一样，投身智慧茶业。

　　从2018年开始，为做好质量和品质控制，贵茶集团陆续建设了“贵茶联盟”大数据管理系统、动态质管数据库和ERP生产数据系统，明确质量、安全和品质关键控制点，实现动态监控与智能生产，以及从田间到茶杯的全程质量与安全控制。

　　“我们提出，让天下人喝干净茶，规模量产的品牌产品对品质的稳定性要求更高，精细化拼配必须从人工向机器智能转化。”贵茶集团副总经理周维说，通过利用数字化技术，贵茶解决了名优茶规模生产品质稳定性难以控制的问题，打破了行业“明前茶”的局限，实现了常年各等级产品品质持续稳定目标，确保周年生产，且所有产品百分之百达到欧盟标准。

　　“收集并分析大数据，构建数据模型，实现智能管控，是贵茶发展的必经之路。”周维说，去年，贵茶集团还开始建设基于数据的风味设计和智能品控数据库，目前已完成初步模型。

　　大数据“基因”的植入，让贵阳的茶园越来越绿、贵阳茶香味越来越浓。近年来，贵阳以“跨区域、跨季节、跨品种”拼配为方向，积极进行茶叶加工技术创新，已有清洁化初加工线100余条、精制加工线10条、碾茶生产线2条、抹茶生产线1条，掌握红、绿、白三大茶类加工工艺和抹茶生产技术，涉足黄、青、黑茶生产，有力提升了茶叶加工水平，产品的品类、品种、产量都有了质的飞跃。

　　除了在种植、加工环节，大数据还在销售环节助力贵阳茶实现精准营销，提升知名度和影响力。2019年，全市实现干茶产量1.49万吨，产值达29亿元，产品远销欧美，享誉海内外。

　　龚静说，大数据为贵阳茶产业上规模、上档次奠定了基础，下一步将促进大数据与茶产业融合得更加广泛、深入，让大数据为贵阳茶产业创新、升级发展发挥更大作用。

In June, the tea hills are as green as daisies, and the fragrance of tea overflows the fortifications.

Right now is the peak season for summer tea production. Among the ten thousand mu of selenium-rich tea sea in Kaiyang County, a ridge of tea trees stretches along the mountain, the mountains are high and the clouds are low, and the eyes are green.

After the beginning of summer this year, the temperature has risen and the rainfall has been abundant. In the 6,800-mu demonstration base of Kaiyang Nangonghe Selenium-enriched Tea Industry Co., Ltd. in Guizhou Province, located in Bazi Village, Longgang Town, the tea is growing satisfactorily. "The temperature and humidity of the tea garden are very good, and the pH of the soil is also suitable, but it is short of nitrogen and potassium, so it is time to fertilize." Li Jingping, the general manager of the company, sat in the monitoring room of the office building and made precise decisions on the management of the tea garden, "Big Data Very 'smart', made it easy and effective for us to manage the tea garden."

Among the lush tea trees, there are tall poles, and the cameras installed on them are like "eyes", observing the growth of tea leaves and the situation of the tea garden all the time; In the house”, sensors collect information such as temperature, humidity, pH and other information in real time. In the monitoring room, this information can provide data support for tea garden management through calculation and analysis.

"Big data allows us to prescribe the right medicine, fertilize in a targeted manner, and predict and prevent pests and diseases in advance, which saves a lot of manpower, material and financial resources." Li Jingping said that in recent years, the company's tea production has steadily increased by about 10% every year.

In order to ensure the quality of tea, Nangonghe Tea Company also conducts pesticide residue testing on tea through the traceability system. Today, Kaiyang selenium-enriched tea has become a business card of "clean tea" in Guizhou.

"Although we were hit by hail this year, we also produced tens of thousands of catties of famous tea. It is estimated that 100,000 catties of summer tea can be harvested." Li Jingping said.

With the development of the model of "company + base + cooperative + farmers", Nangonghe Tea Company also led local villagers to plant more than 2,000 mu of tea, providing jobs for farmers, especially poor households, and giving priority to purchasing their green tea. Today, all the villagers in the first and second groups of Bazi Village have grown tea, with an annual per capita income of more than 20,000 yuan.

Good tea has been produced since ancient times. Guiyang has high altitude, low latitude, cloudy fog, no pollution, and interlaced mountains and hills. It is the most suitable area for tea cultivation. At present, the city's tea gardens have an area of 280,000 mu, and 230,000 mu of tea gardens have been put into production. "In recent years, Guiyang has cultivated and expanded a number of leading tea enterprises. At present, there are 139 tea production enterprises and cooperatives, forming a large, medium and small tea processing cluster. Many tea enterprises use big data technology and intelligent equipment to promote Traditional processing is developing towards mechanization, standardization, cleaning and intelligence." said Gong Jing, director and researcher of Guiyang Tea Office.

At present, more than ten tea companies have joined the smart tea industry like Nangonghe Tea Company.

Since 2018, in order to do a good job in quality and quality control, Guicha Group has successively built the "Guicha Alliance" big data management system, dynamic quality management database and ERP production data system, to clarify the key control points of quality, safety and quality, to achieve Dynamic monitoring and intelligent production, as well as whole-process quality and safety control from field to cup.

"We propose that to allow people all over the world to drink clean tea, mass-produced brand products have higher requirements for quality stability, and refined blending must be transformed from manual to machine intelligence." said Zhou Wei, deputy general manager of Guicha Group. Using digital technology, Guicha has solved the problem of difficulty in controlling the quality stability of large-scale production of famous teas, broke the limitation of "Mingqian tea" in the industry, and achieved the goal of continuous and stable quality of products of all grades throughout the year, ensuring annual production, and 100% of all products. meet EU standards.

"Collecting and analyzing big data, building a data model, and realizing intelligent management and control are the only way for the development of Guicha." Zhou Wei said that last year, Guicha Group also started to build a data-based flavor design and intelligent quality control database. The preliminary model has been completed.

The implantation of big data "genes" makes the tea gardens in Guiyang greener and greener and the fragrance of Guiyang tea stronger and stronger. In recent years, Guiyang has been actively innovating tea processing technology in the direction of "cross-regional, cross-season, and cross-variety" blending. There are more than 100 clean primary processing lines, 10 refining processing lines, 2 tea production lines, and matcha tea production lines. 1 production line, master the processing technology of red, green and white tea and matcha production technology, get involved in the production of yellow, green and dark tea, which has effectively improved the level of tea processing, and the category, variety and output of products have made a qualitative leap .

In addition to planting and processing, big data also helps Guiyang tea achieve precise marketing in sales and enhance its popularity and influence. In 2019, the city achieved a dry tea output of 14,900 tons, with an output value of 2.9 billion yuan. The products are exported to Europe and the United States and are well-known at home and abroad.

Gong Jing said that big data has laid the foundation for Guiyang's tea industry to increase its scale and quality. The next step will promote the integration of big data and tea industry more widely and deeply, so that big data can play a greater role in the innovation, upgrading and development of Guiyang's tea industry. .
