At present, it is a good time for spring ploughing, spring management and spring planting. In the field of Jianghuai land, when farmers grab the farm, all kinds of agricultural equipment show their magic power, and scientific and technological personnel enter the field… There are busy scenes everywhere.
Early in the morning after the rain, Zhao Jun, head of the agricultural technology station and special commissioner for science and technology in Ketan Town, Lujiang County, Anhui Province, drove to the shouhan rice planting family farm in zaogang village to guide the management of the wheat field. At the end of the farm, the fields look green. Zhao Jun said that at present, a large area of wheat has entered the jointing stage. It is urgent to do a good job in field management in spring in time to lay a solid foundation for high yield and harvest of wheat. On the ridge, he asked the farmer Jiang shouhan about the prevention and control of wheat diseases and pests, and carefully observed the growth of wheat.
At the head of a small wheat field, Zhao Jun saw white mildew on the leaves of several wheat plants. “You see, the wheat here has powdery mildew.” Zhao Jun told Jiang shouhan that powdery mildew is a common disease in the process of wheat growth. After the disease occurs, it will affect the photosynthesis of wheat, reduce the panicle and grain weight, and even lead to wheat production failure. “This disease spreads rapidly and does serious harm. It should be found and controlled early to ensure the healthy growth of wheat.”
“What medicine do you need?” Jiang shouhan looked anxious. Zhao Jun made the prescription at the scene: “now it is the initial stage of the disease. 20% three zolazone emulsion can be used for 20 milliliters, and 30 kg of water should be sprayed evenly. Once the spray is applied, the disease will be completely eradicated.” Hearing Zhao Jun’s words, Jiang shouhan was completely relieved. He grinned.
While talking with Jiang shouhan, Zhao Jun’s mobile phone rang. He received a call from Yuan Yihong, a villager of Xiaodun group in Xiaodun village, who said that there was mildew in his rape field. He hoped that he would “feel the pulse” and see what disease the rape had.
After hanging up the phone, Zhao Jun hurriedly said goodbye to Jiang shouhan and rushed to Xiaodun group immediately. “I don’t know what’s going on. Many fields have this situation.” Yuan Yihong, who has been waiting in the field, is worried. “The Rape Stalk has blackened, and the mildew is very serious. It is sclerotinia disease.” Zhao Jun knew the reason as soon as he saw the rape field.
Zhao Jun told yuan Yihong that we must seize the current critical period of Sclerotinia sclerotiorum prevention and control, adopt plant protection UAVs and spray fluconazole acyl hydroxylamine for timely prevention and control. During the prevention and control, leaf fertilizers such as boron fertilizer and potassium dihydrogen phosphate should be added to enhance the stress resistance of plants, improve the seed setting rate and 1000 grain weight, and ensure that rape can achieve stable and high yield. “After the guidance of experts, I feel much more secure now.” Yuan Yihong breathed a sigh of relief. “Being able to diagnose and prescribe medicine for crops is only the basis. The key is to improve agricultural output and increase farmers’ income through agricultural technology.”
At about 2 pm, Zhao Jun came to batun rice and shrimp breeding professional cooperative “work” in chenbu community on time. He said with a smile: “one day, I feel flustered when I don’t turn around in the field. I always feel like I’ve lost my soul.” In the crayfish seedling breeding base of the cooperative, the square shrimp ponds are neat and uniform, and the hoses continuously deliver oxygen to the pool. Zhao Jun carefully checked the pH value, salinity and dissolved oxygen of the shrimp pond through the data of the Internet of things. “At this stage, the focus is on water quality control to ensure the survival rate of shrimp seedlings.” In order to keep up with the pace of rural revitalization, the cooperative has built a 2200 Mu rice shrimp co cultivation base in Ketan town. Increasing agricultural benefits should be based on technology and cannot leave the market. In the past two years, under the guidance and support of Zhao Jun, the cooperative has adopted the combination of planting and breeding to breed high-quality shrimp seedlings in the early stage and connect single season Japonica Rice in the later stage, so as to reduce idle fields, improve land output rate and maximize benefits.
“The rice shrimp co cropping model has achieved the effect of ‘dual use of one land and double harvest of one water’. The comprehensive benefit is more than three times that of rice monoculture. This year, it should be able to achieve a net profit of about 4000 yuan per mu.” Hao Jiandong, chairman of the cooperative, sincerely said that with the hands-on “transmission” of agricultural technology “consultants”, he had a foundation for the development of the cooperative.
The last stop is Chengchi village, where large grain growers talk about their diligent homes. The annual seed soaking of early rice will begin again. The quality of seed soaking and disinfection will directly affect the yield of early rice. “Seeds are the ‘chip’ of agriculture. The benefits of modern agriculture must be hidden in seeds.” Zhao Jun said firmly.
“Early rice seedling blight is caused by the invasion of fungi and viruses. Once it is invaded by its bacteria, it is useless to spray the best pesticide, and its harm can not be controlled.” Zhao Jun opened the conversation, “we especially remind farmers to dry the rice seeds for 1-2 days before soaking them. When disinfecting, they generally soak the seeds intermittently for 12-24 hours, and then use chemicals to mix seeds before sowing, so as to prepare for early rice transplanting in April and clarify food safety production.”
Zhao Jun spoke seriously, talked frequently and listened carefully. “Agricultural technology experts come to the door to carry out agricultural technology promotion, which has brought tangible benefits to our farmers.” The joy of talking about Youqin is beyond expression. “As a special commissioner for science and technology, I always insist that farmers study what they grow and learn what they need. I am a ‘general practitioner’ of crops and provide farmers with all-round technical services.” As the sun set, on his way home, Zhao Jun said from his heart, “seeing the good quality of grain, the improvement of production capacity and quality, and the increase of farmers’ income is the happiest thing in my life.”
Today, there are 242 science and technology commissioners like Zhao Jun in Lujiang County. They are bending down, pulling up their trouser legs, walking down the ridge of the field, going deep into the front line to carry out production guidance and technical services for the masses, help improve the quality and efficiency of agricultural production, lay a foundation for high yield and harvest, add vitality to science and technology, and increase the driving force for Rural Revitalization. “Science and technology commissioners have unique skills. They are all ‘general practitioners’ of crops. They are not only the propaganda team of the three rural policies and the disseminator of agricultural science and technology, but also the leader of scientific and technological innovation and entrepreneurship and the leader of the common prosperity of the masses. They are also the vanguard of promoting the transformation of scientific and technological achievements into the countryside and the new force of implementing the Rural Revitalization Strategy. They have become the most beautiful scenery on the agricultural and rural front.” Wu Zhou, chief agronomist of Lujiang County agricultural and rural Bureau, sighed that the special commissioner for science and technology moved the agricultural technology training classroom to the field and Lbx Pharmacy Chain Joint Stock Company(603883) door, answered the problems encountered by the people in production and life on the spot, and taught technology by hand, so that farmers can understand and see it as soon as they hear it, so that more farmers can rely on science and technology to increase their income and become rich.
