Problems solved by technology

The control of jujube madness is difficult, and the control method of cutting off the transmission route by eliminating the virus-infecting insects has been difficult to promote and implement in production; secondly, the whole body of the jujube tree will be infected with the virus soon after being partially infected and will carry the virus for life. Surgical treatment and chemical treatment such as drug infusion have problems such as continuous drug use and recurrence of symptoms; the application of virus-free seedlings cannot rule out the possibility of re-infection

Embodiment 1

[0028] From 2010 to 2012, in Sanhuan Village, Yiyang Town, Feicheng City, Tai'an, using the cultivated healthy jujube seedlings as rootstocks, round jujubes and jujubes were grafted in early April by double tongue grafting and skin grafting. In June of the following year, 50 annual grafted seedlings of Yuanling jujube and Changhong jujube were selected. On the jujube tree with severe disease, choose jujube mad branches that germinate arbuscular branches at the top and bottom, take the diseased skin on it, cut it into 1.0cm×1.0cm squares, and use it as inoculation material. At the base of healthy grafted jujube seedlings, about 5cm away from the ground, choose a part with a smooth surface. According to the thickness of the seedling stem, cut squares with a size of 1.0cm×1.0cm and a diameter of 1.0cm to 1.5cm. Cut a square opening; the dry thickness is 1.5-2.5cm, cut 2 square openings, the square openings are opposite, staggered up and down by 3cm; the dry thickness is more than...

Abstract

The invention discloses a cultivating method of jujube seedlings resistant to jujube witches broom. According to the cultivating method, wild jujube seedlings breeding robustly are adopted as rootstocks, jujube head branches growing robustly in the current year of healthy jujube trees are adopted as scions, grafting is carried out in spring, head striking and pinching are carried out in time to cultivate the healthy and robust jujube seedlings, the healthy jujube seedlings are subjected to inoculation cultivating through prepared inoculation materials resistant to jujube witches broom, the jujube seedlings highly resistant to jujube witches broom are obtained, and the incidence rate of jujube witches broom is lowered greatly; and through the method, the jujube seedlings obtain resistance to jujube witches broom, occurrence of jujube witches broom is effectively controlled, and a feasible approach is provided for prevention and control of jujube witches broom.

Description

technical field [0001] The invention belongs to the technical field of jujube seedling cultivation, in particular to a method for cultivating jujube madness-resistant jujube seedlings. Background technique [0002] Jujube (Ziziphus jujuba Mill.), belonging to the Rhamnaceae (Rhamnaceae) genus Ziziphus, is native to my country and is the largest dry fruit tree species in my country. Jujube, as a traditional woody food and a special economic forest tree species in my country, has a documented cultivation history of more than 3,000 years. Jujube is rich in nutrients (amino acids, vitamins, mineral elements), and is a first-class nourishing food. At the same time, it has high practical value in traditional Chinese medicine. At present, my country has nearly 99% of the jujube tree area and output in the world, and occupies 100% of the international trade market of jujube products in the world. my country is the largest producer of jujubes and the only exporter of jujube products...
