硅对植物的有益作用及其对草坪草研究的启示

作为地壳中含量第二的元素,硅对植物的生长发育具有显著积极作用。通过分析硅在植物体内的分布、植物吸收硅的途径以及硅在植物抗逆过程中的积极作用,指出硅对草坪草和草坪管理的研究中具有如下几点启示:硅能够促进草坪草生长,缩短建植时间;提高植物水分利用效率,节约灌溉量;提高草坪草抗非生物胁迫能力,扩大建植区域;减少草坪和绿地管理中氮磷使用量,缓解土壤劣化;提高草坪绿地抗生物胁迫能力,减少农药使用量。

Benefits of silicon nutrition on plants and its enlightenment to turf grass research

As the second element in the earth's crust,silicon evidently benefits plant growth and development.After discussing the silicon distribution in plants,channels of assimilating silicon for plants,as well as the positive role of silicon on stress condition,some enlightenments of silicon nutrients to turf grass and turf management research were drawn as following: Firstly,addition of silicon could promote turf grass growth and shorten the duration of turf establishment;secondly,it could improve water use effic...
