玉米是我国重要的农作物,每年仅病虫害就造成约1000万吨的产量损失。2007年农业部主推的玉米重大病虫害综合防治技术通过采取农业(如选择抗性品种、适时播种、合理施肥、控制田间积水、结合间苗及时拔除病苗、减少田间菌源、适时收获等栽培措施和合理轮作、间作、土壤深翻等耕作措施)、物理、生物技术,协调使用化学农药的综合防治,将重大病虫的危害控制在经济水平以下,确保玉米高产、稳产、优质、高效。本文选摘了其中四项主要病虫害的防治技术,供读者参考。
Corn is an important crop in China, and pests and diseases alone cause about 10 million tons of yield loss each year. In 2007, the comprehensive prevention and control of major pests and diseases of maize promoted by the Ministry of Agriculture adopted cultivation measures (such as selection of resistant varieties, timely sowing, reasonable fertilization, field water control, timely removal of disease seedlings with thinning seedlings, reduction of field bacteria sources, timely harvesting, etc.) And reasonable rotation, intercropping, soil deep plowing and other tillage measures), physics and biotechnology, and the coordinated use of chemical pesticides to prevent and control the harm of major pests and diseases below the economic level so as to ensure high yield, stable yield, high quality and high efficiency of corn. This article picks one of four major pest control techniques for readers reference.
