水稻是我国的主要粮食作物,全国65%的人口以稻米为主食。因此,水稻生产在我国国民经济中具有极其重要的地位。栽培上可以通过水分管理、调节土壤肥力,提高水稻对肥料和光、热、CO2(二氧化碳)等资源的利用率,进而获得高产。但在实际生产中,因不科学的肥水管理技术而导致的资源利用效率低下,水体、大气环境污染严重,病虫草害加剧等现象屡见不鲜,这严重地制约了水稻高产潜力的发挥。
Rice is China’s major food crop, with 65% of the population taking rice as its staple food. Therefore, rice production plays an extremely important role in our national economy. Cultivation can be through the management of water, soil fertility regulation, improve rice on fertilizer and light, heat, CO2 (carbon dioxide) and other resources utilization, and then get high yield. However, in actual production, inefficient use of resources due to unscientific management of fertilizer and water, serious pollution of water body and atmospheric environment, exacerbation of pests, diseases and weeds and so on are common occurrence, which severely restricts the potential of high yield of rice.
