Which broadcasting system is better, DJI or Feifei?

You can directly see the contrast of the playback effect. For the extremely flying broadcast system, let me make an answer:

Demonstration of seeder operation was carried out in Anhui, Hunan, Hubei, Jiangsu, Heilongjiang, Jiangxi, Guangdong, Shaanxi and other major rice producing areas. At the end of August, the first batch of flying drones broadcasted rice and ushered in a bumper harvest. The following is a comparison chart:

The above picture shows the effect of a cooperative in Shaanxi after sowing with a sowing system. It is estimated that the yield of this piece of rice will reach 800 kg, which is about 60 kg higher than the average yield of artificial sowing. Zheng Fujun, the head of the cooperative, said that the drone rice direct seeding reduced their workload, which not only shortened the sowing time, but also improved the effect. 15 mu of paddy field, it takes one day to sow artificially, and the drone can complete it in ten minutes. He also mentioned that the dosage of drones is more accurate and uniform than that of artificial sowing mu relying on experience. The dosage of direct seeding rice seeds per mu is about 3.3 kg, which is more economical than manual sowing, and can ensure uniform rice planting density and high germination rate.

In another case, in April, Feifei used the sowing system to sow grass seeds for the grassland in Hongyuan, Sichuan, to speed up the ecological restoration of the grassland.

As for DJI's broadcasting system, there is no relevant official article to explain its effect.
