The drainage area is nearly one-third of the northern canal in Beijing, and the river is gradually being paid off. Solar energy disinfection, ozone de-worming, biological agent fumigation ... 16 new technologies to reduce pesticide use are being used in more than 100,000 mu of farmland on both sides of the river to reduce chemical agents' intrusion into water bodies. Yesterday, the Municipal Bureau of Agriculture made a concentrated demonstration of these new technologies in Tongzhou District. In the future, they will be applied to all the millions of acres of farmland in the Northern Canal Valley.
Green metal rods, bright solar panels, look like street lights, but the lights around a more ring of wire mesh. Yesterday, the device poked on the head of Yongledian Town in Tongzhou District attracted the attention of many agricultural technicians. They came from various agricultural districts and counties in the city, and came to Tongzhou to learn the "genuine scriptures" for new technologies for pesticide reduction.
"This is the solar pest sedation and killing lamp." Zheng Zhiqiu, an expert from the city plant protection station, began to explain this unique "street lamp." This lamp is very powerful, it can convert the daytime solar energy into electrical energy, stored in maintenance-free batteries. At night, it automatically turned on the high-voltage electrode network and the phototaxis lights, causing all pests to ignore the "moths".
One such lamp can control 30 acres of land, and each crop can reduce the spraying of pesticides 2 to 3 times. As this voice did not fall, one of the big guys next to it triggered people's interest again. “This is the invention of the Beijing Invention and Innovation Award for Outstanding Invention—The Ozone Disinfector.†Zheng Jianqiu said while patting the huge exhaust outlet of the machine, he said that it can turn liquid medicine into smoke, and at the same time, it can save energy without sacrificing efficacy. The dose is two to four percent.
The data shows that in the regions where these new technologies are applied, each vegetable reduces the use of pesticides by 3 to 8 times as a whole, saving more than 25% of pesticides in the average field.
In the past, farmers in the suburbs of Beijing depended on chemical pesticides for pest control. The use of pesticides was relatively low, and pesticides were used more often. This situation is slowly turning around. The 16 new technologies demonstrated yesterday will be promoted to nearly a million mu of farmland in the Northern Canal Basin within four years. By then, this river basin, which has a total economic volume of about 80% of the city, will burst out with even more vitality. (Reporter Gong Li)
