In recent years, the special crop planting industry has developed rapidly, and the market demand for high-quality special crop products has been increasing. However, the backward sowing technology has become a key factor restricting the high-quality development of the industry—uneven sowing, high seed waste and poor seedling quality have led to unstable yields and quality of special crops, affecting the economic benefits of farmers and the competitiveness of the industry. Against this background, air-suction seeders, with their precise sowing and seed-saving advantages, have become an important driving force for the upgrading of the special crop planting industry.
The core competitiveness of air-suction seeders in special crop planting lies in their high precision and strong adaptability. Different from traditional mechanical sowing that relies on mechanical extrusion to distribute seeds, pneumatic seeders use negative pressure to adsorb seeds, which can achieve single-seed sowing with high accuracy, avoiding the phenomenon of multiple seeds or no seeds in a single sowing hole. For special crops that require strict planting density, such as ginseng and dendrobium, this precise sowing mode can effectively ensure the growth space of each seedling, improve the quality and yield of crops.
It is important to note that not all special crop seeds can be directly used with air-suction seeders. For seeds with small size, irregular shape or uneven weight, pelleting treatment is required to improve the adaptability of the seeds to the equipment. After pelleting, the seeds will have a uniform shape and weight, which can ensure the stability of adsorption during the sowing process and avoid the problem of missed sowing caused by unstable adsorption. For special crop seeds with regular grains, they can be used directly, which reduces the cost of seed processing for farmers.
In the special crop industrial park in Zhejiang Province, a large number of air-suction vegetable seeders have been put into use this year. The person in charge of the park introduced: “We mainly plant high-value vegetables and flowers. In the past, the sowing work required a lot of labor, and the sowing effect was not ideal. Since we introduced air-suction seeders, the sowing efficiency has been improved by 4 times, the seed waste rate has been reduced by nearly 13%, and the seedling quality has been significantly improved. This has laid a solid foundation for the park to produce high-quality special crop products.”
With the continuous development of the special crop planting industry, the requirements for sowing equipment are becoming higher and higher. Relevant R&D institutions and manufacturers have increased investment in technology, continuously upgrading air-suction seeders. The newly upgraded air-suction seeders are equipped with intelligent monitoring systems, which can real-time monitor the sowing situation and adjust the sowing parameters in time, further improving the sowing accuracy and efficiency. At the same time, the after-sales service system is constantly improved to provide timely technical support for farmers.
Experts in the agricultural field pointed out that the popularization and application of air-suction seeders have effectively solved the technical bottlenecks in special crop sowing, promoted the upgrading of the special crop planting industry, and provided strong support for the high-quality development of agriculture. In the future, air-suction seeders will be more widely used in the field of special crop planting, helping to promote the industrialization and scale development of special crops and bring more benefits to farmers.
