A kind of method of black locust hard branch cutting rooting

Abstract

The invention discloses a cutting rooting method for hard branches of robinia pseudoacacia. The method comprises the following steps: selecting one-year shoots of the robinia pseudoacacia as cuttings, and trimming the shoots, so as to enable the shoots to have the mean length being 10-12cm; quickly dipping the trimmed shoots with ethyl alcohol, and soaking with an ABT1 rooting powder solution for 48 hours, and then cutting into a sand substrate of a seedbed; and carrying out cutting, watering thoroughly, and implementing seedling management. The method is low in technical requirements, but the problem of low cutting survival rate of the robinia pseudoacacia caused by secondary metabolites such as tannin is effectively solved; the cutting rooting rate of the robinia pseudoacacia can be up to 95-100%; a technical support is provided for vegetative propagation and seedling of robinia pseudoacacia; and the method has the great application and popularization values.

Description

technical field [0001] The invention belongs to the technical field of plant propagation, and in particular relates to a method for rooting hard branch cuttings of Robinia pseudoacacia. Background technique [0002] Black locust (Robinia pseudoacacia L.) is a large broad-leaved tree of the genus Robinia, which is native to the United States. It was introduced to Europe in the early 17th century (1601) and spread throughout Europe in the 18th century. At the end of the 19th century, the Germans first introduced the source of Robinia acacia to Qingdao, China. From the 1940s to the 1960s, several batches of sources of Robinia locust from Japan, the United States, and North Korea were planted in Liaodong, Tianshui, Gansu, Changsha, Hunan, and North China. At the end of the 1980s, there were 24 provinces, municipalities, and autonomous regions in my country that planted black locusts, and only 6 provinces including Hebei, Henan, Shandong, Shanxi, and Liaoning had 4 billion plants....

AI Technical Summary

Problems solved by technology

The grafting method has a long production period (2 years) and high cost, which limits the propagation speed; the buried root propagation method cannot meet the production needs because there are few roots; the tissue culture rapid propagation method has a fast propagation speed, but the test conditions are high. High cost and prone to variation
