As a globally significant root vegetable, carrot cultivation area and yield have expanded steadily over the past decade. China, the world’s largest carrot producer, cultivates over 6 million mu annually, accounting for more than 40% of global output. However, traditional sowing methods severely constrain the industry’s modernisation process.
1.2 Limitations of Manual Sowing
Traditional manual sowing practices present multiple issues:
High labour intensity and low production efficiency
Difficulty in controlling sowing uniformity, leading to uneven seedling emergence
Heavy reliance on labour, facing dual pressures of rising labour costs and labour shortages
Sowing quality significantly influenced by operator skill levels
1.3 Technical Bottlenecks in Mechanical Sowing
While traditional mechanical sowing equipment has improved efficiency to some extent, it still exhibits notable shortcomings:
Low seed placement accuracy, with common occurrences of double sowing and skipped areas
Poor adaptability to seed size and shape
Difficulty balancing operational speed with sowing quality
High maintenance costs and insufficient reliability
Chapter 2: Principles and Innovative Breakthroughs in Air-Suction Sowing Technology
2.1 Core Technical Principles
En sembradora de zanahorias por aspiración de aire employs negative pressure adsorption principles, utilising a precision-engineered aerodynamic system to achieve accurate seed separation and positioning. Its operational mechanism comprises four key stages:
Negative Pressure Generation System: A high-efficiency fan creates stable negative pressure, forming a uniform adhesive force field across the seed tray surface
Seed Separation Process: Seeds are precisely adhered to the seed dispensing holes under negative pressure
Precise Positioning and Transfer: Rotation of the seed tray conveys seeds to the dispensing position
Accurate Release and Sowing: Upon release of negative pressure, seeds fall precisely into the seed furrow under gravity
