Plant protection machine small package pesticides "fed to feed"

In recent years, with the acceleration of land circulation, the professional cooperation organization of plant protection has gradually emerged. Through the use of large-scale plant protection machinery, the operating efficiency and control effect have been improved. At the same time, with the application of large-scale advanced plant protection machinery, conventional pesticides currently sold on the market have not been adapted to the needs of large-scale professional plant protection machinery in terms of packaging.

Small package "fed and fed" large plant protection machinery

It is understood that the large-scale vehicle-mounted sprayer currently used has a 6-meter-long spray bar and 12 nozzles above it. The arc-shaped droplets are curved and cross each other to achieve full coverage of the ground and uniform spraying. In this corner, this large-scale machine only needs one farmer to drive a tractor and it can spray an acre of land for a few minutes.

In the process of prevention and control, agricultural machinery operators also reflected that although large-scale plant protection machines have increased the efficiency of spraying, counter-productive drugs are a troublesome task: large-scale sprayers can hold 300 pounds of water, and generally require 15 packages of herbicides, in addition to killing. The red spider's medicine and fungicides. Each time the farmer needs a package to a package to remove, encountered the powder but also to fully pour the package of drugs, time-consuming work. The currently used high pole direct-travel large-scale sprayers can hold 560 pounds of water at a time, and most of the pesticides used are still small packaged products, and they are also faced with the problem of time-consuming and labor-consuming work.

"In addition to farm tractors that drive tractors in the ground, there is sometimes a need to add another person to dispose of medicine packages in the ground," said a farmer.

From the medicines currently available on the market, small-packaged pesticides account for the majority, and are basically used in one or two packs per mu. This kind of packaging is just for the convenience of one family to grow several acres of land. If the breakdown is based on the type of pesticide, some of the fungicides and insecticides are in large packages, and the herbicides are basically absent. In addition, in terms of prevention and control effects, most of the large-packaged pesticides are traditional pesticides, and the control effect is general. However, the new products imported by well-known manufacturers are mostly small packages, and it is difficult to see large packages.

Plant protection aircraft "appetite" drill

In November last year, Huantai County, a professional co-operative for the supply and marketing of beneficial grain farmers, started to use plant protection unmanned aircraft to spray wheat herbicides and opened up the province to use aircraft for field plant protection. According to reports, the capacity of the aircraft's medical kit is 10 liters, which is exactly the amount of 10 mu of land. A box of medicine can be sprayed in 10 minutes. According to the conventional method of pesticide application, at least four or fifty pounds of water is used per acre, while the amount of water sprayed by aircraft is less than two pounds.

At present, Daejeon’s application of unmanned plant protection aircraft is still in its infancy, and the spraying effect and related data also need to be further verified. However, as the land circulation speeds up, applications like unplanted aircraft will become more widespread.

“After using the aircraft, the drugs used must also be strictly selected. The nozzles of the aircraft are much smaller than the nozzles of ordinary sprayers. This also imposes higher requirements on water quality and pesticides. The water quality must be pure, and a slight impurity may occur. Blocking the spray head, more importantly, the solubility of the pesticide must be better, and the particles of the powdered pesticide used must be smaller than ordinary ones. If the dissolution is not sufficient, it is also likely to clog the spray head, said plant protection aircraft users.

Qingdao Hailier Pest Control Co., Ltd. has launched fly defense operations in many provinces. According to reports, plant protection aircrafts have certain special requirements for the pharmaceuticals used. If ordinary pesticides are used, the effect is not satisfactory. At present, the company specializes in the development of high-diffusion, high-adhesion properties for unmanned plant protection aircraft. If large planters or cooperatives purchase special chemicals and the land reaches a certain scale, the company can provide free aircraft spraying services.
