Description
Technical Field
The disclosure belongs to the technical field of seed pelleting, and particularly relates to a green Chinese onion seed pelleting formula and a seed pelleting manufacturing method thereof.
Background
The aging of the population and the increase of the population number urgently need the transformation of the traditional agricultural production to the modern agriculture with standardization, intensification and mechanization. Seed planting is a symbolic production mode of modern agricultural production, and fine seeds are the basis of agricultural production, but the fine seeds can exert the optimal production value by being matched with a standard and efficient sowing mode.
Vegetable seeds (such as green Chinese onion seeds) generally have the characteristics of irregularity, light weight and high price, and the characteristics limit that the vegetable seeds are difficult to adopt a rough sowing mode like other grain seeds, so that the shapes of the seeds need to be properly changed, the seeds are modified by increasing the weight of the seeds, increasing the volume, modifying the surface and the like, the mechanical sowing feasibility of the vegetable seeds is improved, the operation difficulty in the sowing process is reduced, and the refinement, standardization and intelligent degrees of the seed sowing are further improved.
Although the current researches on seed pelleting are more, the researches on vegetable seeds such as green Chinese onions are few, the proportion of the formula is not reasonable enough, the weight of the pelleted seeds is too large, and the transportation cost is high; the strength is not enough, and the mechanical sowing feasibility is low; the seeds of the pellets are compact, and the lack of respiration of the seeds leads to the reduction of activity; the burst effect is not ideal, which leads to the defects of irregular seedling emergence and even dead seedlings. In contrast, the research discloses a green Chinese onion seed pelleting formula and a manufacturing method thereof, and the pelleted seeds have the advantages of light weight, high strength, air permeability and uniform bursting, so that the mechanization degree of green Chinese onion planting is improved, the planting cost is reduced, and the labor intensity is reduced.
