In 2022, the No. 1 central document stated that we should comprehensively grasp the supply of grain production and important Shenzhen Agricultural Products Group Co.Ltd(000061) , stabilize the annual grain sowing area and output, and strengthen the support of modern agriculture. During spring ploughing this year, I heard that there are many fresh objects in the field.
Guinan County, Qinghai Province, is located in the transition zone from Gansu Qilianshan Cement Group Co.Ltd(600720) edge to Kunlun mountain. It has high altitude, long light and large temperature difference between day and night. The annual precipitation is only 459 mm, but the evaporation is more than 1378 mm. Under such special natural conditions, only drought and cold resistant highland barley can grow. At present, Guinan County in Qinghai, located on the Qinghai Tibet Plateau, has just kicked off spring farming.
Spring ploughing is imminent, but it encounters drought, which has brought great trouble to Li Baogui, the person in charge of highland barley planting base. The same worry is Hou Wanhong of the science and technology experiment station.
Hou Wanhong and his team have been trying to breed highland barley varieties that are more drought resistant. At present, they are busy with seed germination test and provide data support for field planting through sampling test of seed bank.
These seeds neatly arranged in the cultivation vessel are a new highland barley variety Kunlun 14, which has been cultivated by the base in cooperation with the Local Academy of Agricultural Sciences in recent years. Compared with the previous varieties, this variety is more drought resistant, disease and pest resistant and stress resistant. In 2019, Kunlun 14 began large-scale cultivation, and the yield of highland barley per mu increased from 400 kg to about 500 kg, a full increase of 25%.
"People work hard and heaven helps". I look forward to the precipitation for many days. A spring snow solved Li's urgent need. Although the snowfall did not last long, it is very important for spring farming in dry farming areas such as Guinan county. Li Baogui decided to start the spring sowing immediately.
With the roar of the engine, planters "ready to go" drove from the garage to the field under the command of Li GuiGui. This land, which has been silent all winter, ushered in the busiest time of the year. The cultivator and planter worked at the same time one after another without stopping. Although the agricultural manipulator sat in his seat, he did not operate the steering wheel. Every time when the agricultural machinery automatically walks to the ground, he needs to adjust the direction.
Reducing the use of 50 kg seeds per hectare also saves a lot of costs for the base. The use of less seeds is also the credit of these autonomous agricultural machines. By setting the program, adjusting the motor speed in real time according to different travel speeds and accurately controlling the sowing speed of the planter, the situation of too dense or too thin number of crops can be reduced to the minimum.
After the base introduced farming equipment with Beidou navigation system in 2020, it can not only realize automatic driving, but also easily complete night sowing on the Qinghai Tibet Plateau.
Work at sunrise and rest at sunset used to be the standard work and rest of traditional farming. However, in the Qinghai Tibet Plateau, if the ground is opened during the day, the sowing has not been completed at sunset at night. After one night's wind, all the surface water will evaporate. If the seeds are sown the next day, it will be difficult for the seeds to grow, which is also one of the reasons for the difficulty of crop growth in this land. Therefore, sowing at night is of extraordinary significance to the arid Qinghai Tibet Plateau.

Late at night, the agricultural machinery in the field is still busy. The starry sky on the sectorau and the lights on the agricultural machinery complement each other. After more than ten days of uninterrupted cultivation day and night, Li Baogui and everyone completed this year's spring ploughing task. Spring ploughing sowed not only seeds, but also hope for a year.
[half an hour observation: no negative agricultural time, no negative spring, science and technology, spring ploughing to promote bumper harvest]
According to the statistics of the Ministry of agriculture and rural areas, by the end of last year, there were Shanghai Pudong Development Bank Co.Ltd(600000) agricultural machinery and equipment equipped with "Beidou" positioning operation terminals, including more than 100000 Tractors Equipped with auxiliary driving system. Driverless is unlocking the "new attitude" of smart spring farming. Without agricultural mechanization, there will be no agricultural modernization. The development of modern agricultural science and technology and the Internet of things are providing "new intelligence" for the development of modern agriculture and automation. With your fingers, you can cultivate 10000 mu of good farmland. We look forward to these scientific and technological kinetic energy surging in the field, which can be truly transformed into the joy of harvest in the golden autumn!
