农业部自2004年正式在全国开展测土配方施肥行动。测土配方技术解决了作物需肥特征与土壤供肥之间的矛盾,同时,在肥料利用率、作物产量、改善农产品品质、节省劳力、节支增收等方面上发挥了重要作用。重微量元素作用建土壤养分体系针对香蕉生产中忽视有机肥施用、土壤培肥,钙、镁、硼等中微量元素缺乏、微量元素投入较少、施肥总量不足等现象,在施肥过程中,要秉承“合理分配肥料、重点时期重点施用”原则,才能保证香蕉的营养元素充足。
Since 2004, the Ministry of Agriculture officially launched the soil testing and formula fertilizer operation across the country. The soil testing and formulating technology has solved the contradiction between the characteristics of fertilizer needed by the crops and soil fertilization and played an important role in the aspects of fertilizer utilization, crop yield, quality of agricultural products, labor saving, expenditure increase and so on. The role of trace elements in soil nutrient system for banana production in the neglect of organic fertilizer application, soil fertility, calcium, magnesium, boron and other trace elements in the lack of trace elements less input, the total amount of fertilizer and other phenomena, in the fertilization process, To uphold the “reasonable distribution of fertilizers, focusing on the key period of application” principle, in order to ensure adequate nutrition bananas.
