Determination and development of mechanical properties of garlic sowing in Shandong Province

In recent years, the lack of garlic production equipment suitable for China′s main garlic production areas is the main factor restricting China′s garlic production. In order to promote the mechanization of garlic in China and understand the mechanical properties of garlic sowing in China, the performance of typical garlic sowing machinery in Shandong Province, the first main production area of garlic in China, was determined. The results showed that the average positive bud rate was 90. 0%. The average sowing depth qualified rate of garlic positive bud seeder and flat bud seeder were 91. 6% and 92. 0%. The average reseeding rate of normal bud seeder and flat bud seeder was 5. 3% and 5. 5%, and the average hole rate was 1. 0% and 3. 2%. The operation speed of the hanging type seeder is higher than that of the self-propelled type seeder, but the operation performance is lower than that of the self-propelled type seeder. The operation effect of hand-supported garlic planter is higher than that of hanging garlic planter. In the future, the positive germination rate and operation speed of positive germination seeder should be further improved, and the operation performance of positive germination seeder and flat germination seeder should be improved, and flat germination seeder should be used in suitable areas.
