红麻施用稀土的效果与技术研究

Study on the Effects and Techniques of Rare Earths Application in Kenaf

通过对红麻施用稀土的生理效应及施用技术的研究表明,稀土能有效地促进红麻根系和纤维细胞发育,能有效地延长红麻生长后期的纤维积累时期,提高红麻抗逆能力,增加单株纤维产量,增产幅度1.37 % ～12.91 % ,并摸索出一整套简便易行的施用方法。生产上大面积推广应用14467 公顷,产生社会效益756.92 万元。

The experiment on the physiological effect and application technique of the rare earth was carried out.The result showed that applying rare earth was helpful to improve effectively the development of root and fiber cell,delay the senility,prolong the mid-late growth maximum period,enhance resistance,increase the fiber yield per plant in Kenaf by 1.37%-12.91%,The application method was developed and used in 14467hm 2,produced the social benefit with 7.5692 million yuan RMB.
