Embodiment Construction

[0042] The present invention is further illustrated below by way of examples.

[0043]Such as 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 whe...

Abstract

The invention provides a method for cultivating a cloned avocado rootstock, the cultivating method comprising the following steps: (1) cultivation of a vegetative rootstock; (2) grafting of a second rootstock; (3) yellowing treatment; (4) the second rootstock 2 rooting of rootstock; (5) separation and purpose scion grafting. The present invention utilizes the secondary grafting technology to well solve the problem of grafting between the functional stock such as disease resistance and the target scion. In the method of the present invention, the rooting efficiency of functional rootstocks such as disease resistance can be promoted through etiolation treatment, combined with rooting nutrient solution hanging bottle infusion method or atomization supply method. In the rooting step, the second rootstock is subjected to 360° wave circumcision, and the auxin is used to promote the direct rooting or atomization rooting method 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 method for cultivating clonal avocado seedlings. Background technique [0002] Avocado (English name: Avocado), also known as avocado, avocado, avocado, happiness fruit, is a kind of evergreen tree of Lauraceae Avocado, and is one of the most important woody oil family tree species in the world. The avocado industry has a history of nearly one 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 become an increasingly popular fruit. [0003] With the increase of people's demand for avocado, technicians have also studied the planting technology of avocado seedlings, in order to improve the yield and quality of avocado. Existing avocado planting techniques include various grafting and propagation methods. In the 1970...
