On August 8, 2023, over 30 directors of agricultural machinery and planting cooperatives from Wenshang County, Jining City, Shandong Province, visited Shandong Dangkang Agricultural Equipment once again. All the chairmen expressed that upon coming to Dangkang Company, they felt a sense of security and warmth, and all had a feeling of coming home. This was also their fourth time to return home in recent years.

The chairmen visited the cutting workshop, the welding workshop and the assembly workshop. In the prototype area, veteran users shared their experiences one after another, introducing the usage methods and precautions of each product to new users.
The chairmen focused on learning about the integrated machine of driving harrows and row sowing, especially regarding the phenomenon of large-scale frost damage to winter wheat caused by the cold weather and little rain last winter. The chairmen were deeply touched. After the land was prepared with a common rotary tiller and then sown with a small seeder, not only did a large amount of wheat frost damage occur in Shandong after the beginning of spring, but similar phenomena also occurred in Hebei, Henan, Anhui, Shanxi and other places. The users were very impressed that the wheat sown by rolling it once after sowing or by using a combined machine of driving harrows and row sowing basically did not suffer from frost damage.
Long-term users have all expressed that after using the integrated machine of drive rake and row sowing, the soil is compacted and leveled. Not only is the depth of sowing consistent, but the soil has also been compacted twice, achieving excellent moisture retention, drought resistance and frost prevention effects. There are basically no dead seedlings, and the yield-increasing effect is very obvious. Generally, one mu of land can increase wheat production by 100 to 200 jin. Due to the compaction of the soil, the germination rate of seeds can reach over 95%, basically eliminating the phenomenon of seed hanging. Therefore, when using the integrated machine of drive rake and row sowing, at least 5 to 10 pounds of wheat seeds can be saved per mu.

The chairmen also learned in detail about the Dangkang air-suction no-till precision seeder and the air-blowing precision seeder. And they all expressed that they would change to this one next year.
After the visit, Chairman Zhao Peisheng smiled and said to General Manager Zeng Xiangang, who accompanied the visit, "Mr. Zeng, here we have seen what we wanted to see and learned what we wanted to know. We will definitely not let you worry about the lunch at noon." His words elicited a burst of laughter from the other chairmen.
