As the temperature rises and everything revives, the spring ploughing work in various grain-producing areas is in full swing. Air suction seeders, with their advanced technology and excellent performance, have become the “new favorite” of farmers, helping agricultural production to be more efficient, green and intelligent, and playing an important role in promoting rural revitalization and ensuring food security.
Different from traditional seeding equipment, air suction seeders adopt negative pressure adsorption technology to realize precise seeding, which is the core of their outstanding performance. The working process can be divided into three steps: first, the air suction fan generates stable negative pressure inside the seeding system, which is the power source for seed adsorption; second, the seed suction disc rotates under the drive of the seed metering device, and when passing through the seed box, the suction holes adsorb single seeds under the action of negative pressure, and the adsorption force is controlled to avoid damaging the seeds; finally, when the disc rotates to the seeding position, the negative pressure disappears, and the seeds fall into the seed furrow smoothly to complete seeding.
This precise seeding mode not only ensures the uniformity of plant spacing, but also effectively improves the germination rate of seeds. According to relevant data, the germination rate of seeds sown by sembradoras de succión de aire can reach more than 95%, which is 10-15% higher than that of traditional seeders. At the same time, it can save a lot of seeds. Each mu of land can save 10-20% of seeds, which greatly reduces the planting cost of farmers and improves the economic benefits of planting.
In Liaocheng, Shandong Province, a major grain-producing area, sembradoras de succión de aire have been widely used in spring ploughing. “In the past, it took 5 people a day to sow 10 mu of land, but now with an air suction seeder, one person can complete 30 mu of seeding a day, and the seeding effect is much better,” said a local agricultural technician. It is reported that the local area has introduced a number of air suction seeders this year, and combined with intelligent technologies such as remote monitoring, it can real-time monitor the seeding status and timely solve problems such as missing seeding, ensuring the quality of spring ploughing.
In addition to improving efficiency and saving costs, sembradoras de succión de aire also conform to the development concept of green agriculture. The no-tillage seeding mode of the equipment can reduce soil disturbance, protect soil aggregate structure, and reduce soil erosion and water loss. At the same time, the integrated design of seeding and fertilization can accurately control the amount of fertilizer and the distance between seeds and fertilizer, avoid fertilizer waste and seed burning, and improve the utilization rate of fertilizer, which is of great significance for promoting green and sustainable agricultural development.
With the continuous advancement of agricultural mechanization and intelligentization, sembradoras de succión de aire will be further upgraded and optimized, and will play a more important role in agricultural production. In this spring ploughing season, they are quietly changing the way of agricultural production, helping farmers increase production and income, and adding new momentum to the realization of high-quality agricultural development and rural revitalization.
