Characteristics and Strategies for Natural Disasters of Wheat Production in Baoji During 2021-2022
Summary of the experience in natural disaster management is crucial for safeguarding wheat pro-duction safety.Wheat production in Baoji City was affected by severe autumn rain during the sowing period in 2021-2022,leading to delayed sowing over a large region.Furthermore,the wheat faced natural disasters in-cluding freeze injury,phytotoxicity,and plant diseases and insect pests.To mitigate its impact,authorities in Shaanxi Province implemented the"Disaster Resistance and Strong Management"100-day action plan and the"Double Increases and Decreases"campaign.These strategies were continuously refined,with an emphasis on managing winter and spring irrigation and fertilization,promoting tiller,spike,and grain development,and en-hancing wheat resistance capabilities through the application of Isohomobrassinolide and amino oligosaccharides.Key techniques including winter and spring chemical weeding,early spring control of stripe rust,and early meas-ures to prevent pest and disease outbreaks were used to improve seedling vigor,achieve proper population densi-ty,increase spike numbers and grain weight,and effectively manage natural disasters.Consequently,wheat yield remained stable and increased to reach a historic high..
