The spring breeze blows on the ridges and the drizzle moistens the new seedlings. During the Spring Equinox, in the vast fields, the lively spring plowing scroll is slowly unfolding from south to north.

Listen, the drone is guarding the "cloud".

At the rape base in Baomin Village, Yuanjiang City, Hunan Province, one plant protection drone after another took off. The average daily operating area of ​​a single drone can reach more than 500 mu, and the operating efficiency is more than 30 times that of manual spraying.

Hu Jianhui, an agricultural technician at the Agriculture and Rural Bureau of Yuanjiang City, Hunan Province, told reporters, "When the rapeseed is in full bloom, the plant protection drone can only be used to prevent and treat sclerosis. Because manual entry cannot be made, the use of plant protection drone will be fast and convenient, and the effect will be good."

As one of the main grain-producing areas in Dongting Lake District, Hunan Province, Yuanjiang City has planted an area of ​​408,000 mu of early rice this year. During this spring plowing period, Yuanjiang City will purchase 500 new plant protection drones to build a three-level service system of "drone + agricultural technician + farmers".

Listen, the "iron cow" is cultivating in the black soil.

Haituo Township, Da'an City, located in the western part of Jilin Province, is preparing for the transformation of saline-alkali land and spring farming production. In the farmland, the tractor pulls the fertilizer spreading truck and moves slowly, and organic fertilizer and soil improvers are evenly thrown into the ground. In the office, staff remotely monitor and adjust progress to improve the efficiency of farming preparation.

In Haituo Township, Da'an City, Jilin Province, agricultural enterprise staff remotely monitor agricultural machinery operations. (Photo provided by the interviewee) Ma Liang, head of the Da'an Branch of Sinochem Environmental Restoration (Jilin) ​​Co., Ltd., said, "Now is the spring plowing preparation stage in the Northeast region. This year, we rely on the satellite navigation system to install sensing equipment on the fertilizer spreading truck to achieve accurate walking of the agricultural machinery according to the set route, and can also control the amount of fertilizer spread according to different plots. The drone is equipped with a spectrum camera to take a spectrum data map. Next, the operation machinery is imported based on the sampling information and multi-spectral data map to achieve accurate variable fertilization. Different fertility is invested in different saline-alkali areas, and through intelligent equipment application, we have achieved accurate scheduling of fertilization operations."

Listen, the wheat seedlings "drink" in the fields.

In the spring plowing season, various places gradually usher in the peak of spring irrigation and water use. As the second largest irrigation area of ​​the Yellow River and the largest irrigation area in Shandong Province, the Weishan Irrigation District of Liaocheng City continues to improve its perception network and continuously strengthens accurate prediction and intelligent scheduling. Wang Yubao, a large grain grower, said, "I am at the end of the irrigation area. Due to scientific scheduling, the Yellow River water was used in time this year, which also laid a certain foundation for increasing wheat production and income." Liaocheng City is a resource-based water-scarce city, and its per capita water resource share is less than one-tenth of the country. As an important infrastructure for the Yellow River in Liaocheng to resist drought, Weishan Irrigation District not only undertakes the irrigation task of 5.4 million mu of farmland, but also undertakes the task of supplying water to human drinks, industry, ecological environment, and cross-basin water diversion to Hebei.

Yang Yuguang, deputy director of the Management Service Center of Weishan Irrigation District, Liaocheng City, said that this year, Weishan Irrigation District uses digital means to accurately analyze the drought and crop water demand, induce and store in advance, scientifically allocate, and accurately predict that there will be moisture shortage in Linqing, Gaotang and other places downstream of the irrigation area. Therefore, the Weishan Irrigation District Management Service Center gives priority to allocating water resources to ensure that the Yellow River water is delivered to Linqing and Gaotang first.

In the fields, agricultural drones, agricultural machinery self-driving instruments, intelligent water and fertilizer management systems, etc. have been "new" in turn, unlocking more "new" methods for spring farming, and agricultural production has accelerated from "sweat agriculture" to "smart agriculture".

The Agricultural Situation Schedule of the Ministry of Agriculture and Rural Affairs shows that the current proportion of winter wheat first-class and second-class seedlings in the country is 89.3%, 1.1 percentage points higher than the previous year and 2.6 percentage points higher than the previous year. According to the latest agricultural situation schedule on March 13, 32.6% of early rice has been planted and 3.2% have been planted. Spring wheat in the north has begun to be sown. It is expected that the seedlings of medium rice in Northeast China will begin in early April and large-scale sowing of corn and soybeans will begin before and after May Day.

Sow a grain of millet in spring and harvest ten thousand seeds in autumn. The melody of spring plowing is playing around the country. In China, a bumper harvest is expected.
