Recently, United States Northwest Oregon town of Beaverton unmanned venture company DroneSeed developed a seeding at high speed drones, using compressed air to the seed into the soil. Founder Grant Canary and Ryan Mykita, established the firm's original intention was to change the way tree planting. At present, the drone has been in the United States applied to forest restoration in the Northwest.
DroneSeed 3D maps using several sensors can be, and where for the plant is likely to survive, and finally wrapped in the seed into the soil. DroneSeed battery for 30 minutes, after replacing the battery working continuously for 1.5 hours. Traditional human seed, probably planting 800 seeds per person per day. The same amount of drones is expected to 1 hour to complete.
According to the United States southeast of wood processing industry association, United States planted trees up to 1.5 billion a year, but trees belong to high-intensity manual labor, is hard to find workers. DroneSeed that the use of drones, can reduce the cost of planting trees.
You could say this is a perfect solution, drones have been applied in many fields in recent years. However, we found that drone seeding this, few people do.
Though agriculture now drones are coming of spring, but agriculture drones used to dry up, it should be sprayed. Strictly speaking, many of today's agricultural drones should be called the spray UAV.
To this end, Lei feng's network (search for "Lei feng's network", public interest) consult a couple of drones of agriculture industry, why few people use unmanned aerial vehicle plant.
Tian Xiang Zhu Qiuyang, the founder of UAV:
"We did it about 3 years ago seeded drones, and has applied for a patent. There is one problem, though, is taking drone to sowing, sowing, and the effect is not bad, but there is a limitation is more preparatory work.
Actual sowing words, we main is for rice aerial, aerial is can achieved of, but this seed early need bubble business, bubble finished a night Hou, second days also to put it dried, dried yihou put in material warehouse in, material warehouse is special of, inside has a dumped disc or air, put this seed from material warehouse in to uniform to dumped out, this does has must difficulty. Because unlike the liquid spray, spray directly will be out. Bin, if you want to make it very evenly spread, and is in fact very difficult.
In addition, with the thick aerial sowing technology seeds easier to sow, plant of this herb if the number of plants per square meter is actually bad, dense production may not be high, because too close after poor ventilation plants, insect prone to illness, and the other is its nutrients will not keep up.
UAV Aerial seeding is a direction in the future, practitioners require you to work to find out. "
Green guardian drone Pan Haiyang, founder: Kenzo france
"Sow a panel can, problem was seeds per acre to broadcast how much weight? Mainly to see the MU sow the seeds, some seeds an acre a few kilograms, efficiency of the aircraft is not much. "
Intelligent flying founder, Qi Juntong:
"Technically achievable, but should not be so high. Some soft and some hard, depth requirements also differ. Flying overhead will not go in, flying too low to control difficult.
1) seed is solid and spraying liquid, spread of such substances and radiation in different ways, we need to study different height, solid distribution under way at different speeds in order to make seed of effectiveness can be guaranteed;
2) downwash effects, larger the density difference between the densities of the liquid and solid, and seed size is different, if used to sow the seeds of that might be different had matched speed and wind farm fit; and not as liquid as the downwash effects are basically the same; Kenzo iPhone
3) impact on aircraft of different liquid effect is the effect of humidity, corrosion, moisture, but the seeds of solids different effect on different types of aircraft, in particular, easy access to the radiator and the engine, may cause mechanical failure; "
Qi Juntong also attempted to use the drones seeding, although technologies implemented on the sown, but after taking into account economic performance, scalability and stability, also chose to give up. As far as he knows, there are at present no machines for sowing of experimental projects, but rarely of practical application.
Drone sowing now can search the well-known case should be BioCarbon, are planting trees. Lauren Fletcher founded by former NASA Engineer United Kingdom drone company BioCarbon Engineering last year launched a tree-planting system, technical procedures are similar to DroneSeed. BioCarbon project in South Africa try this planting system, with the goal of planting 1 billion trees a year.
There is no more information on the BioCarbon tree planting, do not know how many trees they planted. In fact, the most important is not the kind of fast, but survival.
