未来提高农作物生产率的动向是,通过以下主要途径,控制农作物基本的生物变化过程:改良光能合成效率;研究生物固氮技术;利用细胞融合和分子生物学方法进行植物育种;应用常规方法进行遗传改良;研究激素机制;改良营养和水份吸收效率;探索具有较大抗性和适宜于竞争的生物区系;研究土壤营养不足、不利气候因子与有毒化学物质对农作物生产的影响。 (一)提高光合作用效率:改良光合作用效率。据科学家估算,绿色植物每天所贮存的能源,等于当今世界能源消耗总量的17倍。主要食用作物通过光合作用全年截获的
In the future, the trend of increasing crop productivity is to control the basic biological change process of crops through the following main approaches: improving the efficiency of light energy synthesis; studying biological nitrogen fixation techniques; using cell fusion and molecular biology methods for plant breeding; applying routine methods for genetic improvement ; Researching hormonal mechanisms; improving nutrient and water absorption efficiency; exploring biologically relevant and competitive biota; and investigating the effects of undernutrition, adverse climatic factors and toxic chemicals on crop production. (A) to improve photosynthesis efficiency: improve photosynthesis efficiency. Scientists estimate that green plants store more than 17 times the amount of energy they consume every day. The main food crops were intercepted through photosynthesis all year round
