Qianlong net, Langfang, Hebei Province, June 6 (Reporter Wang Shi) there is suddenly a "great talent" in the green prevention and control vegetable production base in Niu Camel Town, Langfang City, Hebei Province. More than ten mu of land is sprayed with pesticides, which is completed in minutes. It is a knapsack high-efficiency room temperature smoke spraying machine.

"the knapsack high-efficiency room temperature smoke applicator is a 'stupid machine'," said Zheng Jianqiu, deputy director of Beijing Plant Protection Station, its creator. The knapsack type high efficiency room temperature smoke spraying machine is easy to operate, time-saving and labor-saving. Vegetable farmers only need to pour the pre-adjusted liquid into the knapsack high-efficiency room-temperature smoke dispenser, and then use a small mobile cable trailer to transport the dispenser to the innermost part of the shed where the pesticide is to be applied. The vegetable farmer retreated from the inside to the outside with the pesticide machine on his back, spraying the air above the plant and between the plant rows, and easily sprayed a greenhouse in about five minutes.

"compared with the traditional manual pressing sprayer, the knapsack type high-efficiency room temperature smoke sprayer is powered by an electric engine, which has a wide spraying range and saves physical strength." Zhang Shunzhai, the person in charge of the base, said. In the past, ordinary knapsack sprayers were used, but because the droplets were large and uneven, and the utilization rate of pesticides was very low, only about 30% of the liquid landed on the plants, and it often took two or three hours to spray one mu of land, which was especially labor-intensive. Today, with this "sharp weapon" of spraying, the problems of running, discharging, dripping and leakage of pesticides have been solved. It takes only 5 to 10 minutes to apply pesticides per mu, and the water consumption has also increased from 50 to 150 to 5 to 10 liters per mu.

Lao Sun, a vegetable farmer, said with emotion: "over the past decade, we have all entered the greenhouse carrying dozens of jin spray buckets, so we are too tired to administer drugs, and we are mainly prone to poisoning. And now with the medicine machine, it will be done in a few minutes. "

"the bullets are the same, but the guns are different and the bullets are fired farther and more evenly." Zheng Jianqiu, deputy director of the Beijing Plant Protection Station, said that the range of this knapsack efficient room temperature smoke sprayer can reach more than 10 meters, and the diameter of the droplets formed by the spray is small and uniform, with an average diameter of 50 microns, which is nearly 10 times smaller than that of the conventional knapsack manual sprayer, and the droplets can float in the air for 30-60 minutes, increasing the utilization rate of pesticides by more than 30%.

According to Zheng Jianqiu, it is the most ideal modern and efficient application instrument for facility horticulture in China at present, with the advantages of significant drug saving, water saving, high efficiency and so on. it can be widely used in the prevention and control of agricultural diseases and insect pests in all kinds of facilities, disinfection and humidification of edible fungi, and disinfection and immunity of livestock and poultry breeding places. Not only the utilization rate of pesticides is high, but also the application efficiency is high, the application intensity is low, and the application effect is guaranteed. It is especially suitable for the efficient service operation of specialized prevention and control service organizations of facility agriculture. At present, more than 400 high-efficiency room temperature smoke spraying machines have been uniformly distributed to the Beijing green prevention and control demonstration base. In the future, the whole green prevention and control technology of Beijing will be provided free of charge to the plant protection departments of Tianjin and Hebei and relevant vegetable production bases to jointly promote green prevention and control technology and supporting pharmaceutical equipment.

Because some pesticides need to wear a lot of protective equipment when spraying equipment, it is easy to get heatstroke in greenhouses with temperatures as high as 40 ℃. Today, with a high-efficiency knapsack smoke dispenser at room temperature, the whole greenhouse can be completed in less than 10 minutes without having to be fully armed.

The knapsack type high efficiency room temperature smoke spraying machine is not only easy to operate, but also easy to carry. After filling the liquid, the weight of the whole fuselage is only more than 30 jin.
