摘  要:
选用"常乐"益植素硝酸稀土,研究不同施用方法、不同施用浓度对栽培牧草、天然草地和饲用灌木、半灌木的施用效果。试验结果表明,牧草施用稀土具有显著的增产效果;施用稀土时对播种的牧草可采用浸种或叶面喷施,而对天然草地只能用叶面喷施。叶面喷施的时间以生长初期至始花期较为适宜;浸种与叶面喷施相比,以浸种为好,具有经济、简便、易推广等优点;且可提高种子发芽率,有促进苗期生长之效用。不同种类的牧草对稀土的敏感性不同。

摘  要:
The "Chang Le" nitrate rare earthis selected in this research,cultivated forages, natural grassland,forage shrubs and semi-shrubs are applied by rare earth using different application methods and concentration of rare earth. The results showed that the application of rare earth to pasture has significantly increased yield;seed soaking or foliar spray can be used for sowed forages when applying the rare earth,while only foliar spray can be used for natural grassland. The appropriate foliar spray application time is from the early growth stage to beginning of flowering;compared to foliar spray,soaking is better,with the advantages of economy,simple,easy to promote,etc.;and with the effectiveness of improving the seed germination rate and seedling stage growth.Different types of forages have different sensitivities to rare earth.
