Preferably, in the method for promoting chrysanthemum cutting rooting, the vitamin is vitamin D3 or vitamin complex.
Preferably, in the method for promoting the rooting of chrysanthemum cutting, 1-1.2mL of rooting agent is added into each kilogram of dry cutting matrix based on the dry weight of the cutting matrix.
Preferably, the method for promoting the rooting of chrysanthemum cutting is used for soaking the base of the cutting slip for 3-4 hours after the rooting agent is diluted by 1000 times.
Preferably, the chrysanthemum cutting rooting promoting method is characterized in that the chrysanthemum is golden aster.
Preferably, in the method for promoting the rooting of chrysanthemum cutting, the rooting agent and the rooting liquid are used for improving the rooting speed, the rooting quantity, the root length and the rooting rate of chrysanthemum cutting.
Preferably, the method for promoting the rooting of chrysanthemum cutting comprises the following specific steps of: binding the finished cutting slips, soaking the base of the cutting slips in 1000 times of diluent of rooting agent for 3 hours, then cutting the cutting slips into cutting matrix added with the rooting agent, and placing the cutting slips outdoors for 4-7 months or in an indoor environment at 15-25 ℃.
Preferably, in the method for promoting chrysanthemum cutting rooting, the cutting matrix is peatmoss: vermiculite: the dry weight ratio of the perlite to the various substances is equal to 2:1:1, and the perlite and the rooting agent are uniformly mixed and then are put into the plug tray.
Preferably, in the method for promoting the rooting of chrysanthemum cutting, the plug is a 128-plug.
Compared with the prior art, the invention has the following beneficial effects:
the plant cutting rooting effect is closely related to the air humidity, the temperature and the hormone level besides being related to the physiological characteristics of the plant, the indoor environment is controllable, and the temperature and the humidity are proper, so that the cutting rooting is easy and the rooting speed is high; and the outdoor temperature difference between day and night is large, the temperature and humidity are uncontrollable, and the cutting rooting effect is often not ideal. The method is simultaneously suitable for indoor cutting propagation and outdoor cutting propagation of the chrysanthemums, and has wide application range.
The hormone level is important for influencing the rooting effect of plants, and most of researches of students are focused on the hormone level, and the influence of different hormones and nutrients on the rooting of chrysanthemum cutting is studied in the earlier stage of the subject group, so that the rooting efficiency is different when the formulas of the hormones and the nutrients are different, wherein indolebutyric acid, indoleacetic acid, naphthylacetic acid, 2,4-D and the like can promote the formation of adventitious roots of cuttings, and the higher the content (purity) is, the better the rooting effect of the cuttings is promoted. On the basis, we have made more intensive research and developed a new rooting agent/rooting liquid formula capable of accelerating rooting of golden-silk chrysanthemums by cutting and a corresponding rooting method.
The rooting agent and the rooting liquid are used for accelerating rooting. The research result of the invention shows that the rooting agent and the application method provided by the invention can accelerate the rooting speed, improve the average root number, average root length and rooting plant number, remarkably promote the rooting of the chrysanthemum and have better rooting promoting effect by adding the vitamin.
