试验研究了植物生长调节剂和基质对宝巾插条生根率、根数量、根长度和根直径四方面的影响.提出了判断生根优劣的综合指标Q值,用于扦插宝巾的基质以三合一(珍珠岩、河沙和泥炭土各1/3)基质最佳,其次为珍珠岩.总体说来,以80ppm IBA和50ppm NAA处理插条促根效果最好.用不同材料作基质,有所不同.以河沙作基质时,用50ppm NAA处理为宜;用珍珠岩和三合一作基质时,用50ppmNAA和80ppmIBA处理均可;用二合一(泥炭土和碎塘泥各半)基质时,选择80ppmIBA处理最佳.
The effects of plant growth regulators and matrices on the rooting rate, root number, root length and root diameter of Bao towel cuttings were studied in this paper.A comprehensive index (Q value) Three in one (perlite, river sand and peat soil each 1/3) the best substrate, followed by perlite .In general, with 80ppm IBA and 50ppm NAA treatment of cuttings to promote the best results.Using different materials as matrix , With a different river sand as a substrate, with 50ppm NAA treatment is appropriate; with perlite and triple for the substrate, with 50ppmNAA and 80ppmIBA treatment can be; with two in one (peat soil and half the broken pond half ) Substrate, 80 ppmIBA treatment is the best choice.
