Embodiment Construction

[0012] Between June and July, select the branches of the previous year, with a diameter of 10-20mm and a length of more than 100cm, and remove the twig tips; cut off the 10-15mm long side in the same direction at intervals of 70-80mm on the branches Epidermis: After the branches are sterilized by potassium permanganate solution, they are buried in the soil with a humidity of not less than 20% and a ditch depth of 70-80mm on the same day, and the peeled parts of the branches are placed on the side, covered with soil and covered with plastic film.

[0013] The seedlings can be raised in October of that year. When raising the seedlings, the whole roots of the original buried branches are taken out, and then cut off according to the seedlings, which can be used as saplings.

Abstract

The invention discloses a populus tomentosa breeding technology, including that: during June and July each year, populus tomentosa branch last year with the diameter of 10-20mm and the length more than 100cm is selected and withy tip is removed; barks with the length of 10-15mm at the same side along the same direction are cut at intervals of 70-80mm on the branch; after disinfection of potassium permanganate, the branch is buried soil with humidity not less than 2% and groove depth of 70-80mm, and the part of the branch with bark cut is placed on side face, soil is covered and trodden down, and a mulching film is covered. Seedlings can be pulled up in October the same year, during seedling pulling up, the original branch is taken out in integral root and then is cut off by seeding, so as to be used as tree seedlings. The operation method of the invention is simple and survival rate is high.

Description

technical field [0001] The invention belongs to the field of tree breeding, in particular to a poplar tomentosa breeding technology. Background technique [0002] The natural reproduction of Populus tomentosa mainly depends on the mature poplar seeds, which drift with the wind and fall to the ground to form seedlings. Because the seeds of Populus tomentosa are very small, it is difficult to collect seeds manually, and its wood is delicate, cuttings are not easy to take root, and the survival rate is very low. Generally, Beijing poplar cuttings are used, and then budding is carried out. The breeding needs to be completed twice, which is time-consuming and labor-intensive, and the seedling cultivation cycle is long. Contents of the invention [0003] The purpose of the present invention is to provide a Populus tomentosa breeding technology, which has a simple operation method and a high survival rate. [0004] The technical scheme adopted in the present invention is: [0...
