Research of Ground Cover Plants Arachis pintoi Krap.
& Greg. and Portulaca quadrifida L.
Wu, C.M., C. H. Wu., T. J. Lein
The purpose of this experiment was to study the propagation technology of ground cover plants Arachis pintoi Krap. & Greg. and Portulaca quadrifida L. The Arachis pintoi Krap. & Greg. cutting in 98 plug had more rooting rate, rooting number and root length. The cuttings treated with 500ppm of IBA solution was more economic to induce rooting. The highest root number and longest root length are appeared at the 28th days after cutting. The cost per cutting in plug was 1.11 NT, which was cheaper than direct cutting in field. The proper stolon length in propagation of Portulaca quadrifida L. was 4 cm. The stolon applied with Hyponex No.2 500X can get more weight, which means product more biomass. There was not significant difference between different concentration of IBA solution treatments. Pendimethalin and Fluazifop-butyl are suggested to spray to control weeds at the initial cultivation in orchard. These two herbicides cause less damage to Portulaca quadrifida L.
