From July 15 to 17, 2023, associate researchers ZHANG Ting and LI Lin from the Institute of Millet Research went to the Wu'an and Gaocheng Soybean Millet Belt Composite Planting Technology Demonstration Base to check the millet seedlings and guide the use of herbicides.

Most of the high-quality herbicide resistant millet varieties cultivated in the hilly and dry land demonstration base, among which the majority are herbicide resistant varieties. The combination of herbicide resistant varieties with self-propelled spraying machines greatly improves the efficiency of spraying, from less than 5 acres per person per day to 100 acres per day, achieving light and simplified production and improving production efficiency.

In Gaocheng demonstration base, the soybean millet strip compound planting was conducted, and the millet variety planted in the demonstration base was Gongmi No. 1. Gongmi 1 has the characteristics of high quality and high yield, and it is a millet variety targeted for cultivation in Gaocheng. Gongmi 1 and soybeans use different herbicides and need to be sprayed separately. When spraying, be careful to prevent the herbicide from spreading to nearby crops. Due to the high temperature and hot climate in the early stage, as well as the continuous rainy weather for several days, weeds are relatively large, and the dosage of herbicides can be appropriately increased. In the future, we can select the suitable spraying machinery for the strip compound planting of soybean and millet. In addition, millet varieties that are resistant to the same herbicide as soybeans, such as Jigu 39, can also be selected to achieve weed control by spraying a herbicide and applying imidazolium nicotinic acid, thereby improving production efficiency.
