This year is in the warm winter, the low temperature suddenly falls, it is not suitable for people, not to mention the same for plants. Therefore, spring wheat field management is very important. Nowadays, under the premise of continuous food growth for 12 consecutive years, the government has emphasized that it is necessary to adjust the structure and transfer mode. The area will not increase for wheat, so it is only working hard on yield. How to change the agricultural production mode can not rely solely on the government to increase investment, only to reduce the use of pesticides and fertilizers to make a fuss, to improve the technical content of wheat cultivation.
The four-level linkage created by the Chinese Academy of Agricultural Sciences and Xinxiang City of Henan Province has promoted the agricultural green production and efficiency model. Xinxiang City, as an old model on the agricultural front, actively promoted this work smoothly and provided some valuable experience to the whole country. They are currently proposing large-scale grain producers, professional cooperatives, food enterprises, and high-yielding governments to create farmers. These practices are being rolled out one by one. They need technology to be obtained from experts and reserve for wheat production. The foundation of the wheat planting here is well grasped, the spring tube is early, the measures are grasped, and the grain is well stocked. The next step is to insist on promoting the water and fertilizer management during the jointing period, pay attention to the prevention and control of pests and diseases, improve the management level in spring, and contribute to the harvest of summer grain.
At present, red spiders have occurred in some places and must be prevented in time. It is necessary to eliminate the disease center in time for wheat stripe rust. Focus on the prevention and control of pests such as sheath blight, powdery mildew, red spiders, aphids and the like that often occur in spring. For wheat sheath blight, spray control should be carried out before mid-March to treat powdery mildew. For the wheat sucking insects, the two key periods of the flood season (the middle of April) and the adult period (the end of April and the beginning of May) should be strictly controlled in a timely manner. In the last year, the plots with serious occurrence of the sucking insects should be combined with watering before the jointing. , apply poisonous soil control to ensure control. For plots where weeds occur severely, before reaching the jointing period, the daily average temperature is stable after passing 6 °C, choose fine weather, 10 am to 4 pm, according to different weed species, choose Hummer, Thiasulfuron The herbicides such as thiophensulfuron are sprayed and controlled, and the concentration and technical operation rules should be strictly followed to avoid phytotoxicity. Strictly prevent livestock and poultry from indulging in early spring, and protect the wheat seedlings from safe and healthy growth. Even in large wheat fields, it is impossible to control the germination of the young crops. Otherwise, the wheat seedlings will be injured, the resistance will be reduced, and even the dead seedlings will cause serious crop losses.

Viruses and bacteria are everywhere. Preventing them in advance is the best way to reduce the risk of infection. Wearing a mask and washing hands frequently are crucial. The new type of coronavirus has the characteristics of contact transmission, and the fact that the virus exists on the doorknob of patients with pneumonia has also shown the necessity of paying attention to hand hygiene and wearing disposable protective gloves.
Whether it is going out to purchase daily necessities or buying through online platforms, it is inevitable to come into contact with "foreign" items, such as supermarket shopping carts, packaging bags, express packaging boxes, etc., and more things need to be touched after resuming work, such as It is inevitable to take public transportation, elevators, etc., these places may have been touched by patients or suspected patients. Wearing disposable protective gloves is an effective means to reduce the risk of infection when there is no condition to wash your hands at any time.
