Experimental Studies On Solution Cultural Technology Of Pachira Macrocarpa By

In order to increase the diversity of solution cultural flower, especially in woody plants less phenomenon, the experiment uses Pachira macrocarpa for the materials, selecting culture medium formula, rooting treatment, aeration time by means of different types of hormones, different concentration, different treatment times and comparison mode of production. Studying the characteristic of solution culture rooting to choice the best way for Pachira macrocarpa induce rooting. To promote the application offer foundation of theory and technology.1、Rich tree rooting medium choice, through comparing the pearl powder, husk and water of rooting index, root and plant growth to determine the best rooting medium, consider the status as a basis for future research. The experimental results show that with clean water as medium of rooting medium is more suitable for the rich tree root growth, the rooting index287,that is3.72times with perlite rooting index.it is2.19times the coconut husk.2、Root treatment options, we choose to cut off all the native roots, the rooting index of356.51, is2.05times the retention of all native plants root. In addition to the root ventilation ventilation ventilation mode selection in the morning and the evening of15min, the rooting index is115.53.3、The Rooting hormone is determined,through compared the rooting index, rooting state,growing state and achieve the finished time, we determined that NAA100ppm is the best hormone concentrations of rooting, the rooting index is339.25that was significantly higher than that in the other4treatments, the rooting hormone soaking time is also very important, the choice of culture methods NAA100ppm soaking for60minrich tree hydroponic rooting.4、To compare the mode of production, in order to A type pipeline training mode, training mode and the column water cultivation pattern comparison, found that A type pipeline training mode hydroponic Pachira unit cycle per unit area into commercial hydroponic plants up to922lines, and the later maintenance management easier. A type pipeline training mode not only train number, and beautiful appearance, is the ideal training mode, is worthy of study and popularization.
