At present, the tractor is one of the effective methods with low threshold. In addition to being simple and easy to use, the tractor itself can also be used for pesticides and other agricultural implements. Therefore, the comprehensive cost of one-time input has certain advantages in practicality. There will be insufficient motivation to accept the new method. The plant protection machinery industry is restricted by the farming time. The busy season from March to September is the peak season. In addition, the plant protection machinery is idle during the remaining days of the pest control season. Plant protection machines will cause insufficient motivation for farmers to accept new methods.
Although the efficiency of tractor spraying is not much different from that of plant protection machine, and the cost is slightly lower, the efficiency of tractor spraying is higher than that of airplanes under suitable terrain, and the requirements on the terrain are higher. Plant protection machines can use remote sensing technology to imitate the terrain and fly, and the terrain restrictions are small. It can basically fly, and the plant protection machine can also save some medicine. Planters and entrepreneurs said: The tractor can be used in the early stage of crop growth, but it will not work in the later stage of crop growth. For high-stalk plants, crop tractors with more seedlings on the ground cannot go to the ground. After the crops grow densely, the plant protection machine becomes indispensable.
Another planter of high-value cash crops said: Manual spraying will have a loss of about 10%, and the loss rate of mechanized spraying such as tractors is even higher. For crops such as cotton plant protection machine flowers, the ratio of spraying service cost to loss is just a fraction. It is very cost-effective to spray this kind of land with a plant protection machine.
At the same time, plant protection machines will not be limited to field crops such as rice, rape, wheat, and cotton.
