Spring ploughing is in progress, and technology helps harvest. In recent years, with the in-depth advancement of agricultural modernization, intelligent agricultural machinery has gradually entered thousands of households, changing the traditional farming mode. Air-suction seeders, as a representative of intelligent sowing equipment, have been widely promoted due to their high precision, high efficiency and seed-saving characteristics, helping farmers get rid of heavy manual labor and embark on the road of efficient farming.
The working principle of air-suction seeders is based on negative pressure adsorption, which uses the difference between internal and external air pressure to stably pick up single seeds and accurately put them into the soil. This mode fundamentally solves the problems of uneven sowing, seed waste and low emergence rate in traditional sowing, and effectively improves the quality of sowing. It should be emphasized that the seeder has certain requirements on seed shape, and only seeds with regular grains or those treated by professional pelleting can ensure the stability of adsorption and sowing accuracy. Compared with traditional sowing methods, air-suction seeders can save a lot of seeds, reduce planting costs, and at the same time ensure that the seedlings are uniform and strong, laying a good foundation for subsequent growth.
In Jilin Province, a major grain-producing province in China, many farmers have experienced the convenience brought by air-suction seeders. Wang Hua, a farmer in Changchun City, has been using air-suction seeders for three years. He said: “The air-suction seeder is easy to operate, and one person can operate it. It can sow 150 mu a day, which is 10 times more efficient than manual sowing. Moreover, the sowing is uniform, and the emergence rate is more than 95% every year.” It is reported that this year, Jilin Province has invested more than 800 air-suction seeders in spring ploughing, covering various grain crops such as corn and soybeans, which has greatly improved the efficiency of spring ploughing.
With the support of agricultural machinery subsidy policies, more and more farmers are willing to purchase air-suction seeders. At present, the domestic air-suction seeder industry is developing rapidly, with continuous improvement in product quality and variety. Some high-end models are equipped with intelligent monitoring systems, which can real-time monitor the sowing situation and send early warnings for abnormalities, further improving the intelligence level of sowing. In addition, relevant departments have also carried out technical training to help farmers master the use and maintenance skills of air-suction seeders, ensuring that the equipment can play its maximum role.
The wide application of air-suction seeders has not only improved agricultural production efficiency, but also promoted the transformation of agricultural production mode from extensive to intensive. In the future, with the continuous development of intelligent technology, air-suction seeders will be more integrated with big data, Internet of Things and other technologies, bringing new impetus to the high-quality development of agriculture and helping farmers achieve better harvests.
