淮南市小麦种植现状及技术优化策略OA

Based on the wheat planting practice in Huainan City,Anhui Province,this paper systematically analyzed the current situation of wheat production and the weak links in cultivation,and proposed targeted technical optimization strategies.Wheat production in the study area is dominated by semi-winter wheat with a typical rice-wheat rotation system.Integrated farming and sowing technologies including deep tillage,fertilization,seeding and soil compaction have been widely popularized,and plant protection drones and other modern pesticide application equipments have been applied for disease and pest control.Nevertheless,prominent deficiencies still exist in variety selection,sowing management,popularization of deep tillage,fertilization regulation and disease and pest control.In view of the above problems,the corresponding improvement measures were proposed.Select high quality,high yield and disease-resistant wheat varieties,such as Annong 0711 and Huacheng 3366;adopting mechanical drill seeding to improve sowing quality.The suitable sowing period for semi-winter wheat is early to mid-October with the seeding rate of 12.5-15.0 kg/667 m2;the suitable sowing period for spring wheat is from late October to early November with the seeding rate of 15 kg/667 m2.Implement deep ploughing with a depth of more than 20 cm once every 2 to 3 years.Carry out soil testing and formulated fertilization,with the application rates of 15 kg/667 m2 pure nitrogen,6 kg/667 m2 phosphorus pentoxide,10 kg/667 m2 potassium oxide and 1.5 kg/667 m2 zinc sulfate.Focus on the prevention and control of wheat sharp eyespot and Fusarium head blight.Benzene ether difenoconazole and thifluzamide are recommended at the returning green and jointing stage for sharp eyespot,while cyanovirin and tebuconazole are applied at the early flowering stage to control Fusarium head blight.This study can provide a scientific reference for the sustainable and high quality development of wheat industry in local areas.
