Propagation Technique

 Abstract:: Different agents, from the cutting medium, time and soaking agents, etc., cutting propagation of Phlox subulata survival factors were studied.

Phlox subulata (phloxsubulata) is sky blue Hydrangea flowers onions families (genus phlox), hardy perennial evergreen herbaceous perennial flowers, meadow-like,UGG boots, evergreen, ground cover, generally high 15cm, multi-branched, short-term can be covered with the ground, flowers purple, pink or white, flower diameter 2cm,UGG boots cheap, length of style than the calyx, bright green leaves in spring, summer and dark green in winter by the cream into a gray-green leaves and flowers at the same time open. Phlox subulata native North America, Japan successfully introduced, and a large number of for environmental Lu received good results, named Chi Ying. Flowering from May to December, the first flowering of a May 4, second flowering 8 to 9 months, until December there are sporadic flowers open in succession. Red flowers blossom green background, very colorful, phlox Phlox subulata is a unique variety of strains. It is not only high coverage and ornamental value but also very strong, is good to be flowers, and has planted a simple, adaptable, drought, cold, salinity of soil characteristics.

Phlox subulata seeds or hard to form a very small species, mainly by asexual propagation. Phlox subulata cuttings affect reproduction or survival factors study to determine the optimal conditions for cutting propagation and improve the level of cutting propagation.

1. Materials and methods

1.1 Materials

selected grew well,cheap UGG boots, no plant diseases and insect pests of Phlox subulata, the year Johnson clipping leaves and twigs lobular variety, will be cut into about 10cm cutting, cutting oblique cut under notches.

cutting medium: peat particles: coarse river sand: perlite mixture according to the ratio of 1:1:1. Make cuttings bed.

rooting powder type and concentration:

1. Genwang: 50 times and 100 times the two concentrations.

2. Naphthylacetate: 50 times and 100 times the two concentrations.

3. rooting like: 50 times and 100 times the two concentrations.

Method: cut a good cuttings were randomly assigned to 200 plants / group, 300 / group strapped, immersed in different concentrations of ABT with a good solution, and set a different time gradient.

first cutting a group does not use any rooting cuttings, rooting conditions as control and survival rate were observed.

The first group was the comparison of different concentrations of ABT Gen Wang, Gen Wang rooting powder concentration of 50 times and 100 times, soaking time set two gradient 5min, 10min select the sand used for the cutting medium, twenty days after the statistics.

second group comparison of different concentrations of ABT naphthylacetate, NAA rooting powder concentration of 50 times and 100 times, soaking time set two gradient 5min, 10min select the sand used for the cutting medium,UGGs, twenty days after the statistics.

third group rooting for different concentrations of ABT-like comparison, root-like rooting powder concentration of 50 times and 100 times, soaking time set two gradient 5min, 10min select the sand used for the cutting medium, twenty days after the statistics.
