Problems solved by technology

The rootstocks cultivated by the traditional method of raising seedlings with gourmet kiwifruit and Chinese kiwifruit as the main species are all fleshy roots. Although they have good grafting compatibility, the seedlings cultivated with this kind of rootstocks are not resistant to waterlogging and are prone to root rot, causing tree Weakness and death of the tree

Abstract

The invention provides a method for improving waterlogging tolerance of kiwifruits. The method comprises the following steps that 1, actinidia valvata seedlings are cultivated; 2, intermediate stocks are grafted on the actinidia valvata seedlings; 3, the intermediate stocks are grafted on cultivated varieties. The method for improving the waterlogging tolerance of the kiwifruits has the advantages that 1, kiwifruit fleshy root stocks of actinidia deliciosa, actinidia chinensis and the like are directly adopted, so that sensation of waterlogging and other problems are solved; 2, the intermediate stocks are grafted on the actinidia valvata seedlings, so that the problem of the compatibility of actinidia valvata to the actinidia deliciosa, the actinidia chinensis and the like is solved, the phenomenon of 'small feet' cannot occur, and the growth vigour of the grafted kiwifruits is good.

Description

technical field [0001] The invention belongs to the technical field of fruit trees, and more specifically relates to a method for planting kiwi fruit. Background technique [0002] Kiwifruit belongs to Actinidiaceae (Actinidiaceae) Actinidia Lindl (Actinidia Lindl) plant, this genus is naturally distributed in China as the center, is a vine deciduous fruit tree, has 54 species, 21 varieties. Delicious kiwifruit (A.chinensis.var.deliciosa A.Chevalier) and Chinese kiwifruit (A.chinensis.Planch.var.chinensis) are currently cultivated and utilized, accounting for more than 95%. In recent years, the area of ​​kiwifruit (A.arguta) and kiwifruit (A.eriantha) has been increasing. my country is the world's largest producer of kiwifruit. In 2017, the planting area of ​​kiwifruit was 3.468 million mu and the output was 2.44 million tons, accounting for 67% of the world's total area and 60% of the total output. Kiwifruit is an important characteristic fruit in my country, and promotin...
