Method for increasing survival rate of chrysanthemum out-of-season cuttage

Abstract

The invention discloses a method for increasing the survival rate of chrysanthemum and belongs to the technical field of chrysanthemum planting propagation. According to the technical scheme, the method is characterized by comprising the steps that in the middle ten days of October, cut chrysanthemum cuttage seedlings are soaked in a rooting powder treatment solution for 5 min and then cut into amedium, after cuttage, the seedlings are placed outdoors, the chrysanthemum cuttage seedlings root after seven days, and the rooting rate is 100%, wherein the rooting powder treatment solution is twoor more of ART1 with the concentration of 0.5-1.5 mg / L, NAA with the concentration of 0.2-0.6 mg / L and IBA with the concentration of 0.1-0.5 mg / L, and the medium is two or more kinds of vermiculite, perlite and turfy soil. According to the method, by screening rooting powder different in kind and concentration, the chrysanthemum cuttage seedlings are subjected to cuttage into different mediums, finally the chrysanthemum cuttage seedlings root in short time, and the aim of strong seedings is achieved. According to the method, the problem of high cost of chrysanthemum out-of-season cuttage in the prior art is effectively solved, the time of chrysanthemum out-of-season cuttage is effectively shortened, the survival rate of chrysanthemum out-of-season cuttage is increased, and the chrysanthemum propagation cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of chrysanthemum planting and breeding, and in particular relates to a method for improving the survival rate of off-season cuttings of chrysanthemums. Background technique [0002] Chrysanthemum, a perennial herb of the family Asteraceae, its petals are tongue-shaped or tube-shaped. Chrysanthemum is a precious ornamental flower that has been cultivated by long-term artificial selection. It is one of the top ten famous flowers in my country. It has a cultivation history of more than 3,000 years. People's demand for chrysanthemums is increasing, and due to technical reasons, it is impossible to realize the opening of chrysanthemums throughout the year. However, existing technologies such as florescence regulation, hormone treatment, and low-temperature storage only provide cultivation and management techniques and methods for chrysanthemums when they are cut in off-season, while the formulas for cutting subs...

Problems solved by technology

People's demand for chrysanthemums is increasing. Due to technical reasons, it is impossible to realize the opening of chrysanthemums throughout the year.

However, existing technologies such as florescence regulation, hormone treatment, and low-temperature storage only provide cultivation and management techniques and methods for chrysanthemums when they are cut in off-season, while the formulations of substrates, rooting powder types, and treatment concentrations for off-season cuttings are used in off-season chrysanthemums. less mentioned in cuttings
