不同功能稀土微量元素螯合有机肥的研制及其对水稻发育、产量、品质的影响

Development of Different Functions of Organic Fertilizers with Chelated Rare Earth and Trace Elements and Their Effects on Rice Development,Yield and Quality

针对长期不合理施用大量元素化肥、未经腐熟的农业废弃物等,造成土壤板结、盐渍化、重金属含量超标,导致农产品品质和产量下降等问题,研发了提质增效型、土壤改良型和重金属污染土壤修复型稀土微量元素螯合有机肥,并介绍了有机肥的生产工艺。以水稻为试验对象,连续2 a的田间试验示范结果表明:3种类型的有机肥对提高水稻产量、改善品质、节本增效具有明显的效果,增产幅度为4.1%~11.6%;水稻产品中对人体有益的铁、锰含量增幅为2.81%~87.44%,重金属含量下降4.46%~61.76%;3种类型的有机肥在提高耕地质量、修复土壤障碍因子等方面具有一定的作用。

In response to the problems of long-term unreasonable use of large amounts of elemental fertilizers,none-decomposed agricultural waste,etc.,which cause soil compaction,salinization,excessive heavy metal content,and a decrease in agricultural product quality and yield,the organic fertilizers with chelated rare earth and trace elements for improving quality and efficiency,soil improvement,and heavy metal contaminated soil remediation is developed.The production process of organic fertilizers is introduced as well.The results of two consecutive years of field experiments and demonstrations on rice show that three types of organic fertilizers have significant effects on increasing rice yield,improving quality,and saving costs and improving efficiency.The increase in yield ranged from 4.1%to 11.6%,and the beneficial iron and manganese content in the products increased by 2.81%to 87.44%,while the heavy metal content decreased by 4.46%to 61.76%.Three types of organic fertilizers play a certain role in improving the quality of cultivated land and repairing soil barriers.
