论作物高产

Discussion on Crop High Yielding

阐述了作物高产的概念,分析了作物高产的必要性,指出了要实现作物高产所面临的问题,同时提出了保证我国作物持续高产的途径和建议。作物高产是人类追求的永恒目标,但不同时期作物高产的具体标准不同。作物高产面临严峻挑战,如高产意识比较淡薄,农业生产的资源利用效率太低,农业生产自然环境容量过小,自然灾害发生频繁,水资源短缺,沙漠化、石漠化严重,生物多样性遭到破坏,研究人员流失等。保证作物持续高产要从如下几方面努力:加快新品种审定步伐,保证适宜的生物多样性;注重高产栽培理论和应用技术研究,做到良种良法配套;激活农业耕地流转机制,提高资源利用效率;取消农业税,实行农业补贴。

The paper expatiates the definition and the necessity of crop high yielding, and pointed out the realistic problems to realize crop high yielding, and in the end put forward ways and suggestions to ensure crop sustainable high yielding. The paper believes that crop high yielding is the eternal target of mankind although the criterion for high yield varies with time. Crop high yielding faces severe challenges, such as little high yielding sense, low utilization rate, small capacity of environment, frequent natural disaster, water shortage, desertification, poor bio-diversity, and so on. (The paper suggested that the following measures should be taken in the future: speedup new varieties appraise and approve to ensure bio-diversity, paying attention to study on high yielding theory and technique, activating (arable) land transferring mechanism to enhance resources utilization rate, abandoning agricultural tax and implementing agricultural subsidy as soon as possible.)
