This year's wheat harvest: mechanized harvesting accounts for over 99%, with over 800000 agricultural machinery workers competing for the sky and time. Wheat | homework | wheat harvest
This year's "Three Summer" wheat large-scale machine harvesting began on June 2nd, with over 600000 combine harvesters, over 800000 agricultural machinery operators, and more than 6100 emergency operation service teams fighting for the sky and time on the front line of wheat harvesting, with mechanized harvesting accounting for over 99%.
During the wheat harvest period, the Agricultural Mechanization Station of the Ministry of Agriculture and Rural Affairs and China Agricultural University jointly built the Agricultural Machinery BeiDou Big Data Platform. Over 120000 harvesters equipped with BeiDou navigation were launched, and a total of 5.05 billion pieces of their operation information were captured during the entire harvest period, with a data size of over 30T.
Looking at the difficulty of this year's wheat harvest through data
Firstly, let's take a look at the difficulty of this year's wheat harvest: this is the center of gravity map of wheat harvesting operations during the 2022 wheat harvest period. In favorable weather conditions, the harvesting center of gravity shows a trend of alternating east and west, and advancing northward in a cascade manner. The obvious difference in this year's homework focus map is that the previous homework focus shifted in a circular manner between cities such as Nanyang and Zhumadian in Henan and major grain producing cities in Anhui. This is because due to the continuous rainfall, agricultural machinery workers in Henan have either suspended their operations or went to neighboring cities and counties in Anhui for work first. Due to the impact of rainfall, the harvest window period in Nanyang City is 4 days, which is 7 days shorter than last year.
Looking at the "speed" of this year's wheat harvest through data
Time is tight and the difficulty increases, so various regions are making every effort to increase the speed of grabbing. Agricultural machinery operators operate in a non-stop mode, working day and night. We counted the homework hours from 0 to 6 o'clock during the wheat harvest period and found that during the peak period, which was originally a time of deep sleep, the homework hours exceeded 2 hours. Not only that, there is also an important support for harvesting, which is the upgrading of agricultural machinery equipment. On the agricultural machinery Beidou big data platform, according to statistics, the mainstream models participating in the harvesting battle this year have a feeding volume of 8 kilograms per second, an increase of 3 kilograms per second from ten years ago.
During the wheat harvest period, the average speed of the harvester when working in the field is 3.4 kilometers per hour. When transferring on the highway, their average flow speed reaches 95.9 kilometers per hour.
This year, the largest daily operating area of agricultural machinery appeared on June 3rd, located in Yuhui District, Bengbu City, Anhui Province. The daily operating area of a single machine reached 420 acres, while the local highest operating record in recent years retained by the platform was only 300 acres. How can such homework data be achieved? The local village officials gave us the answer.
Li Kejian, Secretary of the Party Branch of Zhucun, Macheng Town, Yuhui District, Bengbu City: In response to this change in weather, several large harvesters were ordered. The previous machine had a header of about 3 meters, while we had a header of about 6 meters. After our land was upgraded and transformed from a small field to a large field, our land was also leveled and the land area became larger. This large harvester can collect about 6 acres of land in 3 to 5 minutes once.
Looking at the "temperature" of this year's wheat harvest through data
During this year's wheat harvest, you can still feel a lot of warmth. In Dezhou, Shandong, nearly 6000 square courtyards available for wheat drying have been announced on map after map, making it convenient for farmers to plan their grain drying locations according to their needs.
In large agricultural machinery enterprises, thousands of accompanying service teams migrate from south to north along with cross regional machine harvesting teams. They set up a 24-hour service hotline in the background that can respond in 15 minutes, providing emergency repair and other service guarantees for work machinery.
Weichai Lewo Smart Agriculture Customer Service Center Crawler Machine Parts Dispatcher Zhou Haigang: According to the data received from our backend, this year's shredder belt and moving blade have been damaged relatively high. Only two orders have reached more than 1000, and we have dispatched more than 350 service personnel to strive to bring faulty vehicles back to the site in the shortest possible time.
In addition, during the wheat harvest period, more than 3200 cross regional operation reception service stations and more than 12000 preferential gas stations for agricultural machinery supply have been established in various regions, and nearly 1100 "Three Summer" agricultural machinery hotlines have been opened to help agricultural machinery operators solve difficult problems.
News tip: Wheat is divided into winter wheat and spring wheat based on planting time
According to different factors such as planting time, purpose, and planting area, how many types of wheat can be subdivided?
In China, it is mainly divided into winter wheat and spring wheat according to planting time.
Winter wheat is planted in autumn and winter, harvested in summer, and distributed in areas such as North China, the Yellow River, Huaihai River, the middle and lower reaches of the Yangtze River, southwest, and northwest; Spring wheat is planted in spring or early summer and harvested in autumn, distributed in Northeast, Northwest and other regions. The most critical factor affecting planting time is temperature.
Liu Luxiang, Secretary of the Party Committee of the Crop Science Research Institute of the Chinese Academy of Agricultural Sciences: At minus 20 ℃, it is difficult for our winter wheat to safely overwinter. Therefore, you can see that Northeast China is accustomed to growing spring wheat, and we will plant wheat after the temperature rises in the following spring.
Wheat is mainly divided into three categories based on its use: strong gluten, medium gluten, and weak gluten. Strong gluten wheat has high protein content and strong gluten strength, making it suitable for making bread; Medium gluten wheat has medium protein content and gluten strength, suitable for making noodles, Mantou, dumplings, etc; Weak gluten wheat has a softer texture and weaker gluten strength, and is more commonly used in making cookies and pastries.
In addition, in order to adapt to local conditions, varieties such as salt alkali tolerant wheat and water-saving wheat have been promoted more in areas with insufficient natural resources.
Liu Luxiang, Secretary of the Party Committee of the Crop Science Research Institute of the Chinese Academy of Agricultural Sciences: Our current goal in improving wheat varieties is to continuously improve our quality while steadily increasing yield. Practice has proven that high-quality seeds contribute over 45% to increased production.
