The specialized service of plant protection can solve the difficulty of giving medicine to farmers.

In recent years, plant protection machinery in China is undergoing profound changes. with the application of small remote control aircraft, helicopters and large self-propelled sprayers, plant protection operations have begun to realize the transformation from human-backed machines to "machine-backed machines".

On August 12, the "on-the-spot meeting on the Prevention and Control of Major crop Diseases and pests and the safe use of low-toxic pesticides" sponsored by Zhongnong Lihua Biotechnology Co., Ltd. was held in Linyi City, Shandong Province. More than 150 representatives from the National Agricultural Technology Center, Shandong Plant Protection Station, Plant Protection Institute of Chinese Academy of Agricultural Sciences, local plant protection stations, supply and marketing cooperatives, farmers' professional cooperatives, dealers, big growers, plant protection machinery production enterprises and surrounding farmers, watched the demonstration of large-scale plant protection machinery for the professional and unified control of corn and rice diseases and insect pests.

People carry machines to "machines carry people".

At the demonstration site of specialized unified prevention and control of corn diseases and insect pests in Miaoshan Town, Tancheng County, Linyi City, two spray rods of a "giant" were seen spreading out to form huge "wings" while driving into the corn field.

Zhao Jinkai, chairman of Beijing Fengmao Plant Protection Machinery Co., Ltd., said at the scene that this large-scale plant protection machine is a self-propelled ultra-high ground gap sprayer introduced from Italy and assembled in China. It is the most advanced pesticide spraying machine specially used on tall crops such as corn; the medicine box can hold 2.2 tons of liquid medicine and can work in 300 mu per hour, with very high operation efficiency. The height of the ground gap is 2.8 meters, the height of the spray rod can be raised from 0.5 meters to 3.8 meters, and the wheel distance can be adjusted between 2.25 meters and 3 meters according to the planting pattern of the crops. it is worth mentioning that this machine can accurately control the dose of pesticide spraying per mu by computer to achieve variable spray and accurate application.

At the scene of the observation, several old people stood beside their cornfield with manual sprayers on their back, reluctant to get into the cornfield for medicine. Lu Daiqiang, a farmer in Lu Village, Miaoshan Town, said: "on such a hot day, we still have to drill into the corn field in long clothes, trousers, hats, and more than 40 jin of heavy spray buckets. I am too tired to take medicine, and sometimes it is easy to be poisoned if I am not well prepared. If this large machine goes twice in a few minutes, it will be enough for about a dozen of us to work for a day. "

After watching the spray demonstration of "Big Mac," Lu Daiqiang said with emotion that he would never have to worry about playing pesticides in the future.

The professional service of plant protection needs to be vigorously promoted.

Xu Dekun, director of Linyi Plant Protection Station, said that corn crops are tall crops, which are currently 2.1 to 2.3 meters high, and the weather is hot. Coupled with the high intensity of labor, most farmers are unwilling to carry out control, which is even more difficult after heading. With large-scale plant protection machinery, the problem of disease and pest control in the middle and later stage of corn can be solved, and it is possible to carry out the technology of "one prevention and double reduction" of corn. The so-called "one prevention and double reduction" technology is to apply pesticide at one time to treat a variety of diseases and pests in the period of maize trumpet mouth, so as to reduce the occurrence base of insect population in the middle and later stage of corn and reduce the epidemic degree of diseases. it is a new technology to ensure and increase the yield of maize.

"however, it is very difficult to prevent and cure each household, and we must rely on social forces to do a good job in professional services for plant protection." Xu Dekun believes that at present, in the whole chain of the whole agricultural production process, the mechanized prevention and control of diseases and insect pests needs to be strengthened, especially with the increase of family farms and large growers, which puts forward higher requirements for socialized professional services for plant protection.

At the demonstration site of specialized unified control of rice diseases and insect pests in Quanyuan Township, Tancheng County, a large-scale plant protection machinery like "bumblebee" attracted great attention of the participants. This large-scale plant protection machine is also a self-propelled dual-purpose flood and drought sprayer assembled by Beijing Fengmao Plant Protection Company with Italian technology in China.

Chairman Zhao Jinkai said at the scene that bumblebee can also carry out plant protection operations for dwarf crops such as wheat, peanuts and soybeans, and has a good control effect.

Many parties join forces to land the service.

"the production and promotion of low-residue pesticides is difficult to achieve without new and efficient plant protection machinery; without a plant protection professional service team, it will not be possible to land on the ground." Su Yi, general manager of Neutral China, said. The company has carried out strategic cooperation with Beijing Fengmao plant protection. Previously, the company has carried out large-scale promotion of specialized and unified control of crop diseases and insect pests by using new plant protection machinery in major agricultural producing areas in Yinan County and Linyi County of Shandong Province, Runan County of Henan Province and Zhijiang City, Hubei Province, effectively controlling major diseases and insect pests and promoting the sustained and stable development of local agriculture.

Zhang Jinglian, president of the specialized cooperative for farmers in Lanshan District, Linyi City, said that the prevention and control of diseases and insect pests by farmers is time-consuming and labor-intensive, and the utilization rate of individuals buying machinery is also low. According to the market demand, on the basis of the Ministry of Agricultural material Management, a plant protection professional cooperative was set up last year, and large and medium-sized plant protection machinery were purchased, relying on the plant protection solution of Lihua, a middle farmer. This year, we began to carry out full-process specialized plant protection services for local large growers and family farms, which are generally welcomed.

Li Mingli, director of Shandong Plant Protection Station, said that the relative backwardness of plant protection machinery has become a major bottleneck restricting the development of modern agriculture in China. The large-scale plant protection machinery displayed by Beijing Fengmao Plant Protection Company and other enterprises is technologically advanced and evenly sprayed, which not only reduces the amount of medicine used, improves the efficiency of control, but also protects the ecological environment. Plant protection cooperatives rely on the plant protection solutions provided by large companies to carry out the whole process of specialized plant protection services, which has solved the problem of drug administration that has plagued farmers for a long time, and is the direction of development in the future.
