At present, sugar cane in the sugarcane growing areas of Guangxi Zhuang Autonomous Region has entered the seedling pulling stage and is growing well.
Guangxi is the main sugar producing area in China. In recent years, meteorological disasters have occurred frequently and repeatedly, which have adverse effects on the growth of sugarcane seedlings, yield and harvest scheduling. Focusing on the fine sugarcane meteorological service, Guangxi meteorological department deeply digs the value of big data elements, establishes an objective data collection think tank for the whole growth cycle of sugarcane, improves the "digital" indicator model system for the whole sugarcane industry chain, and develops a sugarcane smart meteorological service platform that connects users directly, effectively helps enterprises gain, sugarcane farmers increase income, and effectively protects the national sugar safety.

Building a "One Picture" of Sugarcane Growth Multi source Data Elements
Data is the foundation of digital transformation. Guangxi has complex terrain and landform, many kinds of crops, scattered arable land, and complex and changeable weather and climate situation, which was once a technical difficulty in extracting remote sensing information of sugarcane planting and distribution.
Guangxi meteorological science and technology personnel went deep into the sugarcane area, and through manual collection, elimination, screening and field verification, it took four years to find out the "family background" and complete the satellite remote sensing map of sugarcane planting.
In recent years, Guangxi meteorological department has further built and improved a sugarcane field meteorological observation network with satellite remote sensing, unmanned aerial vehicles, microclimate stations and other earth space integration, multi-party cooperation and information sharing, gathering more than 10 50 types of multi-source data elements, such as seedling growth, agricultural economy, and international interaction, to build a "agrometeorological data+sugarcane production data+socio-economic data" The sugarcane production big data collection think tank has laid a solid data foundation for the smart weather service sugarcane production industry chain.
In Chongzuo, the "sugar capital of China", the meteorological department has built a sugarcane meteorological "production, learning, research and use" base by integrating the resources of science and technology, agriculture, enterprises and other aspects, set up a sugarcane meteorological science and technology academy in Xinhe sugarcane meteorological service demonstration base in Jiangzhou District, and jointly built a sugar cane "meteorological digital farm" test base with Guangxi Fantang Digital Agricultural Science and Technology Co., Ltd, Through the enterprise's digital planting management platform, meteorological data such as temperature, rainfall and soil moisture are integrated to provide scientific and technological support for the enterprise's integrated management of sugarcane water and fertilizer.

Due to the impact of multiple low temperature and cold damage and regional and periodic drought in the early stage, the planting progress in some sugarcane areas in Guangxi is relatively slow.
"It is expected that the meteorological conditions in the next 30 days will be conducive to the growth of sugar cane, and it is necessary to do a good job in the management and protection of sugarcane fields." On April 26, the fourth issue of Guangxi Sugarcane Production Service was sent to various sugar industry departments, sugar enterprises, etc., bringing "timely rain" to the current sugarcane management and protection work, and also providing more guarantees for the "sweet honey industry" this year.
Sugarcane likes high temperature and humidity, and is quite sensitive to drought, low temperature and other meteorological disasters. Guangxi meteorological department integrated and utilized the technical achievements of the world's major producers of sugar yield forecasting technology, sugarcane water fertilizer integration intelligent irrigation forecasting technology, sugarcane harvest income extraction index and other technical achievements, improved the "digital" indicator model system of the whole sugarcane industry chain, carried out intelligent monitoring, dynamic irrigation forecasting, seedling disaster risk early warning and impact assessment Sucrose content, best harvest period forecast, weather forecast for mechanical harvesting operations and other services will break through the barriers of data "collection processing sharing application", and realize the deep integration of multi-source data elements into the whole chain of sugarcane production.
From 2014/2015 to 2021/2022, the average accuracy rate of global sucrose production forecast reached 97%, providing an important scientific basis for the country to formulate sugar prices and import quotas. The integrated intelligent management system of sugarcane water and fertilizer can improve the utilization rate of sugar cane and fertilizer by 30%, save water by more than 50%, and reduce labor costs by 80%; The unit yield of sugar cane reached 8.5 tons/mu, 4 tons higher than that of conventional planting, and the sucrose content increased by 0.5%.
At present, the new technology of sugarcane meteorological service has been popularized and applied to the main production areas of Guangxi and Yunnan. The cost of sugar cane can be saved by about 270 yuan per mu, and the efficiency can be increased by about 2020 yuan. The annual income of sugarcane farmers can be increased by 10000 to 30000 yuan per household.

"We reasonably arranged sugarcane cutting and transportation according to accurate sugarcane meteorological service information, ensuring the normal operation of the sugar factory." Chen Jin, general manager of Guangxi Laibin Dongtang Phoenix Co., Ltd., praised the meteorological department. "The meteorological department has told us what season to plant and when to apply fertilizer to prevent diseases and pests," said Chen Lanxiong, general manager of Guangxi Yuanliang Agricultural Co., Ltd.
In recent years, Guangxi Meteorological Department has actively developed a sugarcane smart meteorological service platform for sugarcane farmers and enterprise users, built a digital demonstration application scenario, and innovated and developed an integrated disaster prevention and loss reduction model of "intelligent prediction+disaster early warning+prevention, control and disposal" in combination with the demand for sugarcane farming, planting, management, harvesting, transportation, pressing, processing and sales, Provide customized services for sugar enterprises and sugarcane farmers, such as location-based intelligent disaster prevention reminders and prevention and control suggestions.
Guangxi ranks first in terms of sugar cane planting area and sugar output for 32 consecutive pressing seasons, and the value of sugarcane meteorological big data is still further highlighted. At present, sugarcane meteorological services cover more than 90% of new sugarcane agricultural operators, large growers, sugar mills, sugar related industries and personnel, and meteorological monitoring and service information throughout the sugarcane growth process are integrated into the big data cloud platform of Guangxi sugar industry. The government and relevant departments, through the efficient use of meteorological data and service information, timely formulate and adjust the "double high" sugarcane production plan, so as to stabilize the planting area of sugarcane at more than 11 million mu, produce more than 6 million tons of sugar, and ensure the healthy and stable development of the sugar industry.
