农药是农业稳产增产不可或缺的保障,需求刚性,稻飞虱虫害开启农药大年序曲。人口增加、食品结构升级和发展生物燃料,推动了全球对粮食需求的持续增长。但全球粮食种植面积却处于下降的趋势,从20世纪70年代的7.5亿公顷,降至目前的6.8亿公顷。粮食种植面积的减少,全球气候变化的日益多变,导致粮食稳产增产的压力日趋上升。根据研究,如果不使用农药,因病、虫害引起的减 Pesticide is an indispensable guarantee for steady agricultural production increase, demand is rigid, and rice planthopper pests and diseases open the prelude of peasants. The population growth, the upgrading of the food structure and the development of biofuels have contributed to the sustained global increase in food demand. However, the world’s food acreage has been declining, from 750 million hectares in the 1970s to 680 million hectares today. The reduction of grain acreage and the ever-changing global climate change have put increasing pressure on grain production to increase steadily. According to the study, if you do not use pesticides, due to illness, pests caused by the reduction
