Preparation method of rooting agent suitable for chrysanthemum cutting

Abstract

The invention discloses a preparation method of a rooting agent suitable for chrysanthemum cutting. The rooting agent comprises, by weight, 20-35 parts of indoleacetic acid, 2-4 parts of compound sodium nitrophenolate, 4-8 parts of glucose, 3-5 parts of Siberia Cocklebur extract, 1-3 parts of Sophora alopecuroides extract, 2-4 parts of a potassium and magnesium fertilizer, 2-5 parts of sodium tripolyphosphate, 1-5 parts of chelated iron and 2-4 parts of activated carbon. The rooting agent has the following advantages: components in the rooting agent can effectively increase the activity of polyphenol oxidase (PPO) and facilitate the formation of calluses; the rooting agent effectively accelerates the cell elongating and splitting speed of cuttings, enhances the hydrolysis of fats, starchesand other contents, and facilitates the formation of root primordia; and the rooting agent can simultaneously promote the rooting of barks and the rooting of the calluses, and obviously increases therooting rate of the chrysanthemum cuttings, and grown roots are white and strong, and have a high absorption efficiency of water and mineral matters.

Description

technical field [0001] The invention relates to the field of plant vegetative propagation, in particular to a preparation method suitable for chrysanthemum cutting rooting agent. Background technique [0002] Rooting agents are auxin compounds belonging to the category of plant growth regulator accelerators. In vegetable production and application, there are indole acetic acid, indole butyric acid, naphthalene acetic acid, root swelling, royal root growth, br rooting agent, compound nitrophenol Sodium and other components, its role is to maintain the apical dominance of the plant in the plant, induce the transport of assimilated products to the product (fruit), and promote plant rooting, etc. [0003] The cultivation of chrysanthemum has a long history, and chrysanthemum has always been loved by people because of its rich color, changeable flower shape and high ornamental value. Chrysanthemum cultivation can be carried out in a variety of ways, and cutting cultivation is on...

Problems solved by technology

At present, the production and supply of chrysanthemums in my country is relatively backward. One of the important reasons is that there are many problems in cultivation. For example, the conventional cutting method can maintain the excellent characteristics of the mother plant of chrysanthemums and is simple and easy, but the rooting time is relatively long. , and the rooting rate is not ideal

The rooting of chrysanthemum cuttings is an important link in the growth process of chrysanthemums. Using conventional cutting methods, there are a series of problems such as mold and rot at the lower incision of the cuttings during the rooting process, long time required for the rooting process of cuttings, and irregular rooting.
