Seed selection is divided into three steps:
1. Preparation of mixed seeds Mixed seeds refer to a mixture of seeds of different crop species or a mixture of seeds of different varieties of the same crop or a mixture of seeds of different production methods and different processing methods of the same variety. Mixed seeds are commonly found in crop mixed seeds, forage mixed seeds, horticultural and flower mixed seeds, and mixed seeds for mixed planting afforestation and grassland vegetation restoration.
The main advantage of mixed seeding of different crop species is that the mixed population has a wider genetic background than a single population, and therefore has a stronger adaptability to external conditions. There are differences in the genetic composition, growth habits, requirements for light, fertilizer and water, soil adaptability, and resistance to pests and diseases of the different components of the mixed sowing. The mixed population has stronger environmental adaptability and better comprehensive performance, which can achieve Complementary advantages. In the sowing of landscape plants such as lawns, the components and proportions of mixed sowing are restricted by the principle of landscape consistency.
2. Seed disinfection Seed disinfection before sowing can kill pathogenic bacteria attached to the seed surface, which is of great significance for improving the quality of sowing and breeding disease-free and strong seedlings. When the seed dressing method is used to disinfect chemical seeds of agricultural seeds, a special agricultural seed mixer is used to mix the dry powder agent with the dried seeds before sowing, so that the surface of each seed is evenly coated with the powder.
Third, the mixing of seeds and cultivation substrate In the process of germination promotion of some crops, it is necessary to uniformly mix the seeds with the cultivation substrate made of humus soil and river sand at a certain ratio.

Recommended selection of mixing equipment:
After research and experiments on the mixing technology of agricultural seeds by the engineers of mixing equipment , it was found that the use of vertical conical spiral or spiral ribbon mixers can meet the mixing needs of agricultural seeds to the greatest extent. Structure, design and manufacture of more suitable agricultural seed mixers.
