烯效唑和多效唑对早熟禾的生物学效应

对草地早熟禾(Poa pratensis)叶面喷施不同浓度的烯效唑和多效唑试验结果表明,烯效唑和多效唑对早熟禾的生长发育有很明显的生物学效应:可以延缓生长,控制成熟叶片的长度;成熟叶片的宽度增加;促进分蘖,增加草皮弹性;叶绿素含量增加,绿期延长,延缓功能叶片的衰老。使用烯效唑和多效唑可以减少生长旺季内的修剪次数,节约剪草费用,另外还可以提高坪用质量。

Biological Efficiency of S-07 and MET on Blue Grass

In field experiment,the biological efficiency of spraying in S-07 and MET at different concentrations were studied.The re- sults showed that S-07 and MET had obvious biological efficiency on Blue grass:S-07 and MET,as plant growth retardants,can re- tard growth and control the length of mature leaf and the width of climax leaf;S-07 and MET can promote tiller growth of Blue grass and elasticity of the lawn simultaneously.The content of chlorophyll increased,green period was prolonged and the aging of functional leaf was inhabited.Making use of plant growth retardants such as S-07 and MET can reduce the frequency of mowing of turf grass and save the cost of mowing.Moreover,the properties of turf grass seedlings were improved.
