Why are chili pepper seeds subjected to pelleting treatment?
The core of pelleting chili seeds lies in adapting to their physiological characteristics and the demands of planting and scientific research, addressing the key pain points in practical applications. The specific reasons are as follows:
Solving the sowing problem: The seeds of chili peppers are small (with a thousand-grain weight of about 3-6g), irregular in shape, and smooth on the surface. Manual sowing is difficult to control the quantity, and mechanical sowing is prone to missed sowing and blockage. After pelleting, the seed size is expanded to 2-5mm, which is suitable for mechanical and semi-mechanical sowing, significantly improving the sowing efficiency and uniformity.
Improve seedling quality: Pelletization coating can integrate functional components such as fungicides, insecticides, and nutrients to form a “protective shell”, which can not only resist seedling diseases such as damping-off and seedling blight and pests such as aphids, but also slowly release nutrients to provide a stable environment for seed germination, thereby increasing the emergence rate and uniformity of seedlings.
Adapt to the demands of scientific research and production: At the scientific research level, it can achieve precise identification and sowing of individual seeds, facilitating the tracking of different varieties’ traits in pepper breeding experiments and reducing experimental errors; at the production level, standardized pelleted seeds can reduce seed usage (by 20% to 30%), lower production costs, and be suitable for large-scale and intensive cultivation.
