Development Status And Trend Of Agricultural Seeders Machine

Due to economic development and social needs, people are more and more inclined to mechanization, and agriculture is no exception, so people's demand for seeders has increased, and their requirements have gradually increased. The following is a brief understanding of the development status and trends of the planter market.

1. Development Status Of Domestic And Foreign Seeder Market

China's seeder market is dominated by traditional grain seeders, and seeders and animal-powered seeders for small tractors still dominate. There are about 500 companies producing seeders, of which only 10 produce seeders for large and medium-sized tractors. The output of seeders and animal power seeders for small tractors has accounted for more than 90% of the output of seeders.

In recent years, China's combined operation seeder market has also developed rapidly. Its seeding machine tools mainly include seeding-towing fertilizer combined operation machines, farming-seeding combined operation machines, soil loosening-fertilization-covering-hole-seeding combined operation machines and Water application-seeding combined operation machine, etc. At present, the film spreading and seeding combined operation machine has been developed. In addition, the promotion of precision seed drills has a strong momentum, and the application of precision wheat seed drills and precision crop drills has been rapidly promoted.

At present, the foreign precision seeder market has reached a fairly complete level. In addition to the perfect seeder, it has a complete land preparation, soil cover, suppression, fertilizer, and pesticide spraying devices, and its seed-discharging devices mostly adopt new working principles, including various strengths. Principle and mechanical seeding principle to ensure single seed precision seeding.

At present, although the development and update speed of the seeder market in China is also fast, there is still a certain gap compared with some developed countries.

2. The Development Trend Of Seeders

Develop direct seeding for joint operations. The sowing joint operation refers to the completion of arable land preparation, fertilization, spraying and other operations at the same time as sowing. The advantage is that multiple operations can be completed at one time, the operation efficiency is high, and timely seeding is guaranteed.

3. Problems With Domestic Planters

(1) The working effect of the outer grooved seed meter is not ideal. At present, most of the grain seeders in the domestic seeder market are externally-grooved wheel seeders. Although there are many models, due to the limitations of the structure of the external-groove seeder, the pulsation of seeding and the inside of the seed groove The uneven distribution is the main factor that is difficult to achieve in semi-precision sowing.

(2) The working efficiency of the seeder is low.The working speed is slow. At present, the working speed of grain seeders in foreign countries has reached 15km / h, and some models even reach 20km / h. Due to the constraints of site preparation quality and soil conditions, the working speed is mostly 8-12km / h. At present, the speed of grain seeders in China is about 4-7km / h, and it is often used in the range of 5-6km / h.
The working width of the seeder is small. At present, the working width of grain seeders in Western Europe is generally 5-6m, and in some countries such as the United States, Canada, and the former Soviet Union, many models can reach 10-15m. Now the width of grain seeders produced and used in China is relatively large Up to 3.6m.
The seeding efficiency of the seeding device is low.
