Problems solved by technology

Traditional grafting methods are mostly based on hard branch grafting and summer bud grafting. The grafting method collects scions in late autumn and early winter, and then stores them. Grafting is carried out before germination in the second spring. Due to the influence of injured flow, the survival rate of grafting is low; Bud grafting is only limited to grafting when the branches can peel off in June, the grafting time is short and the survival rate is low

Embodiment 1

[0027] Grafting in spring: In the spring of the current year (April-May), select 3-year-old Populus euphratica seedlings with a DBH of 1-2cm that have been cultivated in beds as rootstocks, and leave 40cm of shaped stems for pruning, and remove all redundant side branches and buds , at the height of 40cm of the strong branches of the rootstock, cut obliquely into a "horse-shaped" incision, and made a deep cut on the vertical trunk at 1 / 3 of the incision, and wiped off all the buds below the incision of the rootstock; The bottom of the natural hybrid Populus euphratica is used as a scion. Cut the scion to a length of 5-8cm, and keep a strong bud. Make a deep cut upwards on the vertical trunk at 1 / 3 of the inclined plane. The grafting method is to vertically open the rootstock incision with a grafting knife in the middle of the rootstock, and quickly insert the cut scion into the incision. Strong agricultural plastic strips are tightly bound, and then the scion and the butt joi...

Embodiment 2

[0029] Grafting in summer (i.e. June-August) when the rootstock and scion branches are semi-lignified; cut obliquely at a height of 40cm from the strong branches of the rootstock to form a "horse-shaped" incision, and vertically trunk at 1 / 3 of the incision Make a deep cut, wipe off all the buds below the cut of the rootstock, and collect the sprouted branches at the bottom of the natural hybrid Populus euphratica with suitable thickness and vigorous growth as the scion, cut the scion to a length of 5-8cm, and keep a strong bud. The top is cut horizontally, and the lower part of the graft is cut obliquely into a "horse ear shape", and a deep cut is made vertically at the 1 / 3 of the horse ear-shaped slope of the incision. The grafting method is to vertically open the rootstock incision with a grafting knife in the middle of the rootstock, and quickly insert the cut scion into the incision. Strong agricultural plastic strips are tightly bound, and then the scion and the butt joi...

Abstract

The invention provides a grafting propagation method for natural crossbred Populus Pruinosa Schrenk in a full growth period. The method comprises the steps as follows: 1, selection of a rootstock seedling: a Peuphratica euphratiea seedling is selected in spring of the same year and is stumped and pruned, a cut is sheared slantwise into a horse ear shape, and buds below the cut are all removed; 2, screening and processing of a scion: a slip at the bottom end of the vigorous current-year Populus Pruinosa Schrenk with the thickness suitable for a rootstock is collected as the scion, the scion is truncated, a strong bud is retained, the top of the scion is horizontally sheared, and the grafting position at the lower part is sheared into a horse ear shape; 3, selection of grafting time; 4, grafting method comprising steps as follows: a cut is sheared slantwise in a proper position of the rootstock seedling, the cut scion is rapidly inserted into the cut and bound, and the humidity and the healing condition of the graft union are guaranteed; 5, management after grafting: timely irrigation and regular checking are performed after grafting, buds on the trunk and branches are removed timely, and other conditions are consistent with those of normal management of seedlings. The method has the advantages that the grafting survival rate is high, the graft union heals rapidly, the tree grows vigorously, and the grafting time is long.

Description

technical field [0001] The invention belongs to the technical field of forest tree grafting, and in particular relates to a method for grafting and propagating natural hybrid Populus euphratica throughout the growing season. Background technique [0002] Populus euphratica (Peuphratica euphratiea) and poplar gray (Populus Pruinosa) are the oldest and most primitive tree species in the genus Populus. Populus euphratica is naturally distributed in Inner Mongolia, Gansu, Xinjiang, Ningxia, Qinghai and other places, but it is mainly distributed in Xinjiang, especially in the Tarim River basin in southern Xinjiang, where it is the most widely distributed and concentrated; Along the Kashi River and the Hotan River, there are a small amount of distribution in the Yili River Basin and the Junggar Basin. [0003] Populus euphratica and Populus gray are very precious woody plant stress-resistant germplasm resources. They are listed as endangered third-level protected plants by the co...
