Problems solved by technology

At present, it is necessary to select a suitable rootstock variety before grafting seedlings, that is, to cultivate rootstock seedlings. It takes 1 to 2 years to cultivate, and fast-growing varieties also need about half a year. The multiplication cycle of seedlings increases the production cost, such as: salinity-resistant poplar, jujube seedlings, chestnut se

Embodiment 1

[0051] (1). Select Populus Zhongtian with good affinity as the rootstock and Populus sinensis as the scion. Select twigs on the 1-year-old Populus Zhongtian and the 2-year-old Populus sinensis respectively, wherein the rootstock is 2 to 5 in length. Rootless and leafless shoots of centimeters, scions are shoots 2-5 cm long with one bud and one leaf.

[0052] (2). Mix organic mercury and water at a volume ratio of 1:500, and disinfect the rootstock and scion respectively, wherein the rootstock is soaked in pruning, and the scion is soaked in the base, and the soaking time is 15 minutes.

[0053] (3). Naphthaleneacetic acid was diluted with water to be a mixed solution of 200ppm, and the rootstock and the scion were respectively subjected to hormone treatment. Since the hormone concentration was low, the rootstock and the scion were treated by direct soaking.

[0054] (4). Rootstock and scion after disinfection and hormone treatment are grafted by single-bud cutting and grafting...

Embodiment 2

[0066] (1). Select the jujube tree with good affinity as the rootstock, and the crispy jujube tree of Jizhou as the scion, and select tender branches on the 2-year-old wild jujube tree and the 1-year-old Jizhou crispy jujube tree respectively, wherein the rootstock is 2 in length Rootless and leafless shoots ~5 cm long, scions are shoots 2-5 cm long with one bud and one leaf.

[0067] (2). Mix thiophanate-methyl with water at a volume ratio of 1:500, and disinfect the rootstock and scion respectively, wherein the rootstock is soaked in pruning, and the scion is soaked in the base, and the soaking time is 30 minutes.

[0068] (3). Mix naphthaleneacetic acid and indolebutyric acid at a volume ratio of 1:1 and dilute with water to a 500ppm mixed solution. The rootstock and scion are treated with hormones respectively. Due to the high concentration of hormones, the rootstock and scion are quickly dipped. processing method.

[0069] (4). Rootstock and scion after disinfection and ...

Embodiment 3

[0081] (1). Select the wild chestnut tree with good affinity as the rootstock, and the Dahongpao as the scion, and select shoots from the 1-year-old wild chestnut tree and the 1-year-old Dahongpao respectively, wherein the rootstock is 2 to 5 in length. Rootless and leafless shoots of centimeters, scions are shoots 2-5 cm long with one bud and one leaf.

[0082] (2). Be that 0.35% aqueous potassium permanganate solution is used to disinfect the rootstock and the scion respectively, wherein the rootstock adopts pruning soaking, and the scion adopts base soaking, and the soaking treatment interval is 25 minutes.

[0083] (3). Naphthaleneacetic acid, indole butyric acid and ABT rooting powder are mixed in a volume ratio of 1:1:1 and then diluted with water to form a 2000ppm mixed solution. The rootstock and scion are treated with hormones respectively. Due to the high concentration of hormones, the rootstock And the scion adopts the processing method of quick dipping.

Abstract

The invention relates to a rapid tree micrografting propagation method. The method comprises the following steps: (1) selecting two tree twigs with good affinity or twigs of the current year on a tree as rootstocks and scions respectively; (2) respectively performing sterilization treatment on the rootstocks and the scions; (3) respectively performing hormone treatment on the rootstocks and the scions; (4) grafting the rootstocks and the scions in the way of scion grafting or bud grafting; (5) cultivating grafted seedlings in a sand bed; (6) removing rootstock shoots in time; and (7) removing binding plastics after the scion survives and young sprouts grow to 20-30cm, thus completing rapid micrografting propagation of the rootstocks and the scions. The method applies the modern biotechnologies to fine variety breeding, realizes industrial large-scale seedling culture, and the method can be implemented in protected areas all the year round. Compared with the existing grafting seedling culture methods, the propagation method has the advantages of low cost, fast seedling formation, robust growth of nursery stocks and easy transplantation, and can rapidly propagate to obtain great amount of new species of good nursery stocks in a short time.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, in particular to a rapid propagation method for forest tree micro-body grafting. Background technique [0002] my country's agricultural production has changed from single-family operation to professional household and company operation, and agricultural production has changed from traditional scattered and disorderly development to orderly and planned development in accordance with local conditions. With the continuous development of the industry, the traditional seedling cultivation methods of self-fertilization, self-propagation, and self-retention can no longer meet the needs of current industrialization and large-scale development. In the process of seedling cultivation, some transgenic varieties with high-quality characteristics have the problem that they cannot form seeds or have few seeds, which makes the price particularly expensive. It is difficult to meet the needs of large-s...
