Cutting fast propagation method of aronia melanocarpa

Abstract

The invention discloses a cutting fast propagation method of aronia melanocarpa. The method comprises the following steps: selecting an aronia melanocarpa plant to be cultured as a scion mother tree,cutting a strong semi-lignified branch with no diseases or insect pests in a growing period, soaking the lower part of the branch in clear water, placing the branch in a cool environment, and keepingbranches and leaves fresh and alive; acquiring cutting slips by cutting the branch into the cutting slips with a length of 8 centimeters, carrying out disinfection, soaking the lower notches in a rooting agent solution for 2 hours, inserting the cutting slips into a soilless medium subjected to disinfection, maintaining suitable temperature, humidity and illumination conditions, and preventing andtreating diseases and insect pests; and regularly spraying water for moisture preservation, and culturing for 45 days to reach rooting rate of 80% or above, and achieve transplanting conditions, wherein the obtained cutting slips can be used for culturing seedlings for production. The materials in the method provided by the invention are simple and easy to obtain, the operation specifications ofeach link are normative, the culture conditions are controllable, the repeatability is strong, the cost is low, the promotion and the production are facilitated, the rapid propagation of excellent seedlings of aronia melanocarpa is facilitated, and the method has a promotion and application value.

Description

technical field [0001] The invention relates to the fields of agriculture and plant cultivation, in particular to a method for cutting semi-lignified branches of Aroniamelanocarpa in the growth period. Background technique [0002] Sorbus adenocarpa is a tree species of the genus Aronia in the family Rosaceae. It is a tree species introduced from Poland. m, clump-like tree shape, used for landscaping and drought-resistant fruit tree cultivation. Sorbus nigra is suitable for the cold winter climate in Northeast China. In recent years, the cultivation area has been continuously expanding, and there is a shortage of seedlings, especially those with early fruiting and high yield. The use of pruned branches during the growth period to produce seedlings is the best choice to solve the problem of large demand for seedlings and insufficient reproduction in a short period of time. Due to the short period of introduction of Sorbus adenocarba into China, it is not conducive to collec...

Problems solved by technology

[0003] At present, the area of ​​black-fruited Sorbus planted in Northeast China continues to expand, and the development of fruit products also requires a large number of seedlings. The market has great potential for high-quality seedlings. The supply of seedlings by division and layering cannot meet market needs. Overall, , the shortage of seedlings restricts the development of the black-fruited Sorbus industry
