Efforts to combat the issues of lodging and barren stalks in densely planted corn have been significantly advanced by the Hanggin Banner Agricultural and Animal Husbandry Technology Extension Center. The center has actively promoted practical technologies such as precision planting density control and integrated water and fertilizer management.

Since the start of the spring planting season this year, the center has organized three training sessions, educating 149 local farmers and herders. These programs have reached 76 administrative villages across six townships. Additionally, the center has conducted 42 on-site field guidance sessions and provided online solutions for over 800 technical queries.

Field measurements indicate that farmers who participated in the training achieved an average corn yield of 980 kilograms per mu. This represents an increase of 110 kilograms per mu compared to non-participating farmers, translating to a direct income boost of more than 280 yuan per mu. Cumulatively, the trained farmers have seen their incomes rise by over 2 million yuan.

Historically, local corn planting density was around 5,000 plants per mu. The current upgrade to a density of 6,000 to 6,500 plants per mu introduced challenges like lodging and barren stalks. To address this, the extension center implemented a dual approach combining "offline field guidance with online real-time Q&A" and "stationary service points with mobile advisory visits." This method provides hands-on, step-by-step instruction from land preparation and seed selection to seedling growth control, ensuring the effective implementation of dense planting techniques.

In the Balagong Chaokai Village, a 1,000-mu demonstration zone for green, high-quality, and efficient production is concurrently advancing. The focus here is on promoting several key technologies: precision corn planting density regulation, clarified Yellow River water drip irrigation without plastic film, selection of dense-planting-tolerant and new corn varieties, and reduced application of organic fertilizers.

Following the optimization of the dense planting model, the corn emergence rate and uniformity have improved by more than 15%, while the rates of barren stalks and lodging have decreased by 20%.

By leveraging integrated water and fertilizer technology, water usage per mu has been reduced by 10% and fertilizer application by 5%, cutting production costs by 80 to 100 yuan per mu. Furthermore, the adoption of green, unified pest control methods has led to a 15% reduction in pesticide use and a 30% improvement in control efficacy. This approach not only ensures effective pest management but also contributes to the protection of the farmland ecological environment.
