我国是人口大国,解决13亿人吃饭问题始终是头等大事。我国人多地少,耕地面积递减的趋势难以逆转,农业资源短缺,生态环境脆弱,重大病虫害多发频发,干旱、高温、冷害等极端天气条件时有发生,农药、化肥过度使用,农业用水供需矛盾突出。据估计,我国约60%的耕地缺乏灌溉条件,7亿多亩农田常年受旱灾威胁,5亿亩盐碱地有待改良。农业农村经济持续发展的刚性制约因素越来越突出,单纯依靠扩
My country is a populous country. To solve the problem of eating 1.3 billion people has always been the top priority. In our country, there are few people and less land, and the trend of diminishing cultivated land area is difficult to reverse. Agricultural resources are in short supply, the ecological environment is fragile, frequent pests and diseases are frequent, and extreme weather conditions such as drought, high temperature and chilling damage occur frequently.
