| 摘 要： | 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。

| Abstract: | Effect of plant growth regulators on the growth of Poa pratensis ‘Conni’ and Festuca arundinacea ‘Arid’ were studied. The result showed that 125 L/hm2 of 30 to 40 mg·kg gibberellin was advantageous to growth and turning green in eraly spring, 750 L/hm2 of 300 to 400 mg·kg paclobutrazol and 200 to 400 mg·kg uniconazole could inhibit growth and thereby reduced the mowing frequency. Period of validity was 3 months. |
