摘要
东北地区作为重要的粳稻生产基地,担负着国家粮食安全、农民种粮增收、保持黑土地生态平衡的重担。近年来随着对水稻产量的追逐,正确合理施用肥料成为当前东北地区农业绿色、高效、可持续发展的一个重要问题。本文综合了前人有关肥料研究的观点,结合近年来东北地区水稻种植区域的自然情况、施肥现状及存在的问题,探讨本地区高效、绿色稻作生产施肥策略。提出了减氮增密种植,选用适宜品种、配施微量肥,因地制宜改变栽培方式等3种方式提高肥料利用率。以期寻求东北地区水稻生产施肥"高效-优质-绿色"的平衡点,为东北地区水稻种植提供参考。
As the important production base for japonica rice, northeast region bears the burden of national food security, the income of grain crops and the ecological balance of the black soil. In recent years, with the pursuit of rice yield, the correct and reasonable application of fertilizer has become an important issue in green, high efficiency and sustainable development agriculture in northeast China. In this paper, the predecessors' research view, natural situation of rice planting area in northeast China in recent years, current situation and existing problems of fertilizer, efficient and green rice production fertilization strategy were discussed. It is proposed that: First, increasing planting density with reducing nitrogen fertilizer application; Second, Selecting suitable culfivars and applying micro-fertilizer; Third, Changing cultivation methods according to local conditions, three ways to improve fertilizer utilization rate. The aim was to find the balance of "High efficiency-High quality-Green" for rice production in northeast China and provide reference for rice planting in northeast China.
