Embodiment Construction

[0042] The present invention is further illustrated by the following examples.

[0043]like figure 1 as shown, figure 1 A flowchart of a method for cultivating a cloned avocado rootstock is shown.

[0044] The specific operating process of the avocado cultivation method of the present invention is as follows.

[0045] One, the cultivation of vegetative rootstock (the first rootstock)

[0046] ①Seed treatment: select fresh, free from diseases and insect pests, mature and plump avocado seeds, wash, sterilize and peel the seed coat after harvesting;

[0047] ② Germination: The method of germination in sand bed is used for germination;

[0048] ③ Sowing: When sowing, put the tip of the seeds upwards, and it is advisable to cover the seeds with sand; the distance between the seeds is 2cm to 3cm. After covering with sand, pour water and put them in a shaded place to facilitate seed germination;

[0049] ④ Seedling transplanting: Avocado young shoots are 5cm to 10cm high when ...

Abstract

The invention provides a cultivation method of a clonal avocado rootstock. The cultivation method comprises the following steps: (1) cultivation of a nutrient rootstock; (2) grafting of a second rootstock; (3) yellowing treatment; (4) rooting of the second rootstock; and (5) separation and objective scion grafting. The cultivation method utilizes the secondary grafting technology to well solve theproblem of grafting between a rootstock with functions such as disease resistance, and an objective scion. In the method of the invention, the rooting efficiency of the rootstock with functions suchas disease resistance can be promoted by performing the yellowing treatment and cooperating with a rooting nutrient solution suspension bottle infusion method or atomized supply method. In the rootingstep, the second rootstock is subjected to 360 degree wave girdling, and the auxin promotion and a direct rooting or atomization rooting method are used to complete the rooting of the avocado rootstock and the large-scale transplanting of seedlings.

Description

technical field [0001] The invention relates to the technical field of fruit tree cultivation, in particular to a cultivation method of clone oil pear seedlings. Background technique [0002] Avocado (English name: Avocado), also known as avocado, avocado, avocado, and happy fruit, is an evergreen tree of the Lauraceae family and is one of the most important woody oily tree species in the world. The avocado industry has a history of nearly a hundred years in developed countries. In the past 20 years, with the improvement of people's living standards, the nutrition, health and beauty effects of avocado have been recognized by consumers, and it has become an increasingly popular fruit. [0003] With the increase in demand for avocado, technicians have also studied the planting technology of avocado seedlings in order to improve the yield and fruit quality of avocado. The existing avocado planting technology includes various grafting propagation methods. In the 1970s, the Un...
