五种植物生长调节剂对甘草生长的影响

Effects of five kinds of plant growth regulator on the growth of Glycyrrhiza uralensis

通过对甘草喷施1 000倍液爱多收、1 000倍液植物动力2003、500倍液多效唑、0.4%的精肥王和200倍液钾天下进行田间试验,旨在探明不同植物生长调节剂对甘草干物质积累、株高、根长及芦茎的影响.结果表明,5种植物生长调节剂对甘草生长发育均有不同程度的促进作用,综合评价最好的是0.4%的精肥王,其次是1 000倍液爱多收,而500倍液多效唑基本没有促进作用.

The effects of of five kinds of plant growth regulator,Atoni at 1 000 times dilution,Plantpower 2003 at 1 000 times dilution,PP333 at 500 times dilution,Jingfeiwang at 0.4 % and Jiatianxia at 200 times dilution,were studied on dry matter, plant height,length of root of Glycyrrhiza uralensis. The resuits showed that all regulators had the effects to promote the growth of Glycyrrhiza uralensis in differenee degrees. Jingfeiwang showed the best, followed by Atonik,however,PP333 had a little effect.
