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

Embodiment 1

[0023] A method for rapid propagation of Sorbus nigra cuttings, comprising the steps of:

[0024] Select the arborum adenocarpus plant to be multiplied as the collection mother tree, cut the strong semi-lignified branches free of diseases and insect pests during the growth period, soak them in water in time, place them in a cool place, and cut them into 6-8 cm sections as soon as possible. Keep 2 sections, keep the upper leaves, cut off half of the larger leaves, cut the slope of the lower cut, and make the upper cut flat; every 75 or so are tied into a small bundle with a rubber band, and placed in a carbendazim solution with a concentration of 1g / L for 30 days. Minutes later, soak the lower incision in ABT200mg / L rooting agent solution for 2 hours, then prepare the substrate, fill the 72-hole tray, and cut one cutting in each hole. The cutting operation is carried out under shading conditions, and the cuttings are kept in the original growth direction. Insert it directly int...

Embodiment 2

[0026] A method for rapid propagation of Sorbus nigra cuttings, comprising the steps of:

[0027] First select the Arana tree, apply more organic fertilizers in spring, cut off the upper part of the thick branches to promote the germination of the branches, and cut the semi-lignified branches that are strong and free of diseases and insect pests during the growth period. It is better to cut the branches in the morning. Soak it in a bucket in time, transport it to a cool place in time, cut it into 4-6 cm cuttings before cutting, keep at least 2 nodes, and leave 1 leaf, the lower incision slope, the upper incision plane, the thickness of the branches should reach 0.5 cm Tie it into a small bundle with rubber bands, put it in 1g / L carbendazim solution for disinfection for 5 minutes, then soak the lower incision in ABT200mg / L rooting agent solution for 2 hours; remove fine sand, vermiculite, Sieve the four matrix materials of peat and perlite, mix them evenly according to the same...

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...
