1. Planter accuracy
Seeding with a seeder requires as high a precision as possible, and strives to reduce the phenomenon of missed broadcast and multicast. Since many domestic seedling enterprises use high-quality seeds for production, the seed price is relatively expensive. If the seeding accuracy is not high, the seed will be wasted. On the other hand, the increase in the phenomenon of missed broadcasting and multicasting will reduce the seedling rate per unit area of ​​the greenhouse and increase the rate of seedlings and seedlings, resulting in waste of greenhouse resources and increased labor costs. Therefore, the accuracy of the planter is an important indicator of its performance.
The accuracy of the planter is closely related to the seed being sown. Seeds with regular shape and clean surface have high precision for sowing. The sowing accuracy provided by the general manufacturers is based on the shape rules and the surface cleaned seeds, and the highest sowing accuracy is even 99.9%. Since the imported seeds are more regular in shape and the surface is relatively clean, the precision obtained by using the imported seeds for seeding is high. Generally, in the foreign production process, the seeding accuracy can reach more than 95%, while in China, the precision is 90% to 95% or more. Since the seeding accuracy is an important indicator for measuring the performance of the planter, when using the planter, try to use a planter with high seeding accuracy.
2. Planter speed
The speed of the planter is mainly selected according to the size of the seedlings of the manufacturer. In the sowing season, it is generally calculated by sowing for 20 hours a day. For example, a planter with a seeding speed of 120 trays per hour (12 8 holes), 20 hours a day, and 4 days of seeding, the planter can broadcast about 1.22 million seeds. The seedling size of the seeder is within 1.2 million seedlings.
When selecting a planter, it is also necessary to consider the scale of development in the future. After the scale of enterprise seedlings is expanded, the planter can be applied.
3. Planter reliability
The higher the reliability of the planter, the lower the failure rate of the planter. Due to the seasonality of planting in the country, sowing time is particularly important, and the high failure rate of the planter will seriously affect the planting production.
