Method for top grafting of high-quality mango tree on low-quality mango seedling tree

Abstract

The invention provides a method for top grafting of a high-quality mango tree on a low-quality mango seedling tree. The method comprises the following steps: selecting a scion and a seedling tree stock; performing stock management before grafting; grafting; implementing a grafting method; and performing management after grafting. A mango seedling tree has an arbor woody root, the root system is well developed, and thus the survival rate of grafting can be ensured; the mango seedling tree and the high-quality mango tree belong to one family, and the scion and the stock are in good compatibility, so that the success rate of grafting can be greatly increased, and the growth speed of a grafted seedling can be accelerated after grafting; mango trees are relatively good in drought and low temperature resistance, so that the survival rate of grafting can be ensured under both relatively droughty and low temperature conditions, the grafted mango tree can blossom and yield fruit within one year and has the ability of surviving in winter in an open field and blossoming and yielding fruit in the same year. The method for top grafting of the high-quality mango tree on the low-quality mango seedling tree, which is provided by the invention, is simple and convenient and high in survival rate, the coverage rate of high-quality mango varieties can be increased, and the purpose of changing low-quality mangoes into high-quality mangoes can be achieved.

Description

technical field [0001] The invention relates to the field of plant grafting, in particular to a method for grafting high-quality mangoes from inferior mango seedling trees at high positions. Background technique [0002] In my country, mango fruit has been a favorite fruit since ancient times. It is sweet and mellow but not greasy, and it is also an excellent tonic. The fruit can be dried for cinnamon orchard meat and dried fruit. Plants in the genus Mango are less resistant to cold, so they are mostly distributed in tropical and subtropical regions of Asia, mainly in southern provinces such as eastern, southern and southeastern Guangxi, Guangdong, Fujian and the hillsides of Taiwan. Mango trees like warm, humid climates and are not resistant to severe cold. The minimum temperature for mango trees to overwinter is not lower than 0 °C. Once the temperature is lower than 0 °C, the normal physiological activities of the plant will be affected, the absorption capacity of the ro...
