Embodiment 1

[0038] as attached Figure 1-3 As shown, the method for grafting sweet persimmon with poor rootstock and ear affinity of the present invention includes the following steps: (1) rootstock cultivation; (2) collection and treatment of scion; (3) grafting period and operation method; (4) grafting After the management of seedlings, the processing method of step (3) grafting is as follows:

[0039] Rootstock treatment: cut the rootstock at a distance of 10-15cm from the ground with branch shears, cut the cut, choose a smooth and straight side, and cut it at an angle of 45° at a distance of about 1.0cm from the cut, reaching the xylem of the rootstock 1 / 4~1 / 3; cut obliquely at the edge of the cross-section with a knife at an inclination angle of 30°, and then use the knife to cut down about 1.0cm at the 1 / 4~1 / 3 of the cut of the rootstock, matching the cutting edge of the crosscut Then, remove the excised rootstock to form a 45° "wedge";

[0040] Scion treatment: leave a single bu...

Embodiment 2

[0051] Embodiment 2 Specific application examples

[0052] The sweet persimmon seedling production base of Hubei Shiweitian Pharmaceutical Co., Ltd. in Luotian County, Hubei Province tested the method of the present invention.

[0053] (1) Rootstock cultivation

[0054] The rootstock is Junqianzi, and the conventional sowing and seedling raising method is adopted. When the thickness of the seedlings at a distance of 10 cm from the ground reaches more than 0.8 cm, the requirements for grafting operations are met.

[0055] (2) Collection and processing of scion

[0056] The scion sweet persimmon variety is Yangfeng. Collect buds that are full, strong, and free from pests and diseases, and scion collection and storage in combination with winter pruning. 30mg·kg before scion storage -1 The NAA solution can be quickly poured and dipped in order to prolong the storage time. The scion is buried in the moist river sand, and the water content is as high as holding it in a ball, an...

Abstract

The invention discloses a method for grafting sweet persimmons with poor rootstock and ear affinity, comprising the following steps: (1) rootstock cultivation; (2) collection and treatment of scions; (3) grafting period and method, the daily average temperature during the day is 15 ℃, cut off the rootstock 10-15cm from the ground, cut obliquely at an angle of 45° at a distance of about 1.0cm from the cut, cut longitudinally about 1.0cm downward at 1 / 4 to 1 / 3 of the cut of the rootstock, and remove the cut Rootstock, single bud left on scion; (4) Seedling management after grafting. The present invention combines the advantages of cleaving grafting and chip bud grafting to effectively alleviate the problems of weak seedling growth and low survival rate caused by weak rootstock affinity in the production of sweet persimmon seedlings. 8.10% and 20.23% for split grafting and chip bud grafting; at the same time, the healing time of rootstock and ear is short, the seedlings grow vigorously, and the nursery emergence rate is 11.73% and 24.76% higher than split graft and chip bud grafting.

Description

technical field [0001] The invention relates to the technical field of seedling breeding of fruit trees, in particular to a new method for grafting persimmons, which is especially suitable for grafting seedlings of sweet persimmons with poor rootstock and fringe affinity. Background technique [0002] China is the most important country of origin and the largest producer of persimmons in the world. It has rich germplasm resources of persimmons and a long history of planting persimmons. In 2014, the national persimmon production was 3.7308 million tons, accounting for 2.25% of the national fruit production. It accounts for more than 90% of the world's persimmon production. Persimmons are classified according to the sweetness and astringency of the fruit when harvested from the tree. They are mainly divided into two categories: sweet persimmons and astringent persimmons. ), such as the common Mopan persimmon (Diospyros kaki Thunb. Mopanshi); sweet persimmon (Pollination-const...
