利用植物生长调节剂对早熟禾、高羊茅的生长速度进行促控研究表明:返青初期,叶面喷施30～42.5mg/L赤霉素,每公顷750kg药液,可以促进生长,提早返青;叶面喷施300～600mg/L多效唑或200～400mg/kg烯效唑,每公顷750kg药液,可以控制生长,从而减少刈剪次数,喷施1次,药效可持续3个月。
Using the plant growth regulator to control the growth rate of Kentucky bluegrass and Tall fescue, the results showed that in the initial stage of rejuvenation, spraying 30 ~ 42.5mg / L gibberellin with 750kg liquid per hectare promoted the growth and early greening ; Foliar application of 300 ~ 600mg / L paclobutrazol or 200 ~ 400mg / kg uniconazole, 750kg per hectare liquid can control the growth, thereby reducing the frequency of cutting, spraying 1, efficacy can last 3 months.
