Grafting method for winter jujube seedlings

Abstract

The invention relates to a grafting method for winter jujube seedlings. The method comprises the steps that 1, cuttage is performed on winter jujube seedlings in last winter, and the seedlings live through the winter; 2, the roots of the winter jujube seedlings are manufactured into a wedge shape, the angle of the wedge shape is 25-35 degrees, and the seedlings are grafted to stems of wild jujube trees in a cuttage mode; 3, the grafted stems of the wild jujube trees are fully coated with emulsion and wrapped with plastic tape, and grafting of the winter jujube seedlings is completed. Existing wild jujube trees are adopted as a female parent of winter jujubes, the scientific grafting means is adopted, it is ensured that the winter jujube seedlings grow robustly, meanwhile, the winter jujube tree fruiting rate is effectively increased, economic benefits of orchard workers are increased, and the overall grafting technology is scientific in design, easy to implement and easy to obtain.

Description

technical field

[0001] The invention belongs to the field of forestry and relates to a seedling cultivation technique, in particular to a method for grafting winter jujube seedlings. Background technique

[0002] Dongzao is a high-quality late-maturing fresh jujube variety. The fruit resembles a small apple. The skin is thin and the flesh is crispy. The taste is sweet and slightly sour. It is known as the "king of fruit"; Dongzao is also rich in cyclic adenosine monophosphate, which has high health value, so it is loved by people.

[0003] Since the end of the 1990s, winter jujube has formed a development boom in my country. In 2006, the national winter jujube cultivation area was more than 1.5 million mu. However, farmers in my country's newly developed winter jujube production areas have very little knowledge of winter jujube cultivation techniques, and the cultivation technology is seriously lacking, resulting in serious problems such as low yield, poor quality, and even...

Embodiment Construction

[0020] The present invention will be described in further detail below in conjunction with specific examples, and the following examples are only descriptive, not limiting, and cannot limit the protection scope of the present invention with this.

[0021] A method for grafting winter jujube saplings, the steps are:

[0022] (1) cuttage winter jujube saplings in the autumn of the first year, survive the winter;

[0023] (2) In the first ten days of March in the spring of the second year, raise the seedlings of the winter jujube saplings, make the roots of the winter jujube saplings wedge-shaped, and the wedge angle is 25-35 degrees, and insert them outdoors on the stems of the wild jujube trees. The specific method Yes: make a V-shaped incision on the stem of the jujube tree, the opening angle is 25-35 degrees, and the incision should be made on a branch not less than 15cm away from the trunk of the jujube tree; insert the root of the jujube seedling into the incision Inside, ...
