Fangfanghua in the front line ｜ Li Xiufen: The dedication to the meteorology is 20 years of farmers

"For more than two decades, I have witnessed the analysis of agricultural meteorological index technology from single to diversified, meteorological conditions and disaster effects from qualitative to quantitative, meteorological services from single to wisdom and fineness. More and more intelligent, more and more refined. "Li Xiufen, the 13th labor model of Heilongjiang Province, Li Xiufen, a senior engineer of the Institute of Meteorological Sciences, Heilongjiang Province, told reporters.

In -depth research on the fields to conduct research

The timeliness of the forecast service is 3 days to 10 days in advance

In terms of refined weather for farming, Li Xiufen has made a lot of effort.

During the technical period of the agricultural meteorological estimation technology of smart grids, she had been abandoned for more than a month, and finally successfully solved the technical difficulties of the grid sunshine time, the potential steaming amount of crops, and the timeliness of refined agricultural meteorological forecasting service In 10 days, ahead of the guidance of agricultural production.

In response to the problem of insufficient timeliness of the meteorological forecasting of traditional crops and insufficient refinement, Li Xiufen and the team have been in terms of check -in for 3 years to build a comprehensive model of the dynamic meteorological forecast of refined crops. 2%to 4%, produced more than 30 periods, provided an important reference for the National Bureau of Statistics Heilongjiang Investigation Corps to carry out grain output evaluation work, and truly wrote the paper on the land of the motherland.

Meteorological technology to keep food safety

While paying attention to meteorological services, Li Xiufen never relaxed scientific research and continuously carried out scientific and technological research on the needs of national food security "cockpit stones".

Relying on the National Natural Science Foundation of China, she led the team to conduct soybean water control tests, and went to the fields to conduct investigations many times. Due to the limited funding, the shadowing of the water control test is relatively simple, and it is necessary to cooperate manually in sunny ventilation and light transmittance, and multi -person cooperation. There are more weather in the summer, and the sudden precipitation accompanies her and the team will be caught off guard ...

In this way, after more than 500 hardships of day and night, Li Xiufen led the team to obtain high -quality first -hand scientific research materials such as 3650 soil humidity data, 1080 groups of fertility traits data, and 1470 groups of output structure data.

Li Xiufen and the team members played the potential of innovation, introduced the concept of "multi -source collaborative diagnosis", and built the soybean drought diagnosis index systems such as meteorological, soil humidity, farmland conditions and growth, remote sensing index, crop model simulation rate reduction rate, etc. The soybean drought and multi -source coordinated diagnosis technology has reduced the possibility of soybean drought and misjudgment to a certain extent. It has important value and scientific significance for scientific diagnosis of soybean drought in Northeast China and ensuring that soybean stabilizes high yield.

Evaluation methods and standard construction nationwide promotion

In response to the influence of quantitative assessment of meteorological disasters, Li Xiufen proposed the concept of "crop grout index" after concentrating on research, and newly built a bruting index, pumping (pumping) corn (rice) low -temperature cold damage monitoring evaluation indicators, storage organs Evaluation indicators of the reduction of production reduction of dry objects. Compared with traditional methods, the biological significance of the low -temperature cold damage monitoring and evaluation methods and indicator systems based on the WOFOST model is more clear, and the technical level of quantitative evaluation has caused output loss due to low temperature and cold damage. This method is written into the "Crop Model Business Application Technology Guide", issued by the China Meteorological Administration and promoted nationwide.

Li Xiufen pays great attention to the construction of modern agricultural meteorological standards. The meteorological industry standard "Northern Spring Corn Drought Level" was promulgated and implemented in 2015; the national standard "Northern Rice Low temperature and cold damage level" and local standards "Return to Seeding Temperature" were participated in the formulation. Prompt and implement. The formulation and implementation of these standards makes meteorological services be reasonable and evident.

"Grain security is the biggest of the country. The rapid development of modern agricultural meteorological services is effectively carrying the heavy responsibility of ensuring the safety of national food security and helping rural revitalization." Li Xiufen said that she will continue to work hard on the road of meteorological services for agriculture.
