Problems solved by technology

However, the germination of axillary buds to form new shoots is affected by many factors. In the natural state, only a small number of axillary buds can germinate, and most of the axillary buds cannot germinate to form new shoots after artificial defoliation.

Embodiment 1

[0021] The method for promoting shoots of custard apples comprises the following steps:

[0022] 1. Select the branches drawn in the current year and use branch scissors to cut off the top 3cm branches (remove the top). Then remove all or part of the leaves of the custard apple branches that have been removed.

[0023] 2. After the branches are decapped and defoliated, quickly spray the calcium chloride solution with a mass fraction of 5% until the axillary buds are fully wetted.

[0024] 3. After spraying calcium chloride solution for 1 hour, spray 10 mg / L heterocyclic urea cytokinin until the axillary buds are fully wetted again.

[0025] 4. Repeat steps 2 and 3 on the 3rd and 5th days after the branches are topped and defoliated to promote the germination of axillary buds and form new shoots.

[0026] The results showed that: on the 8th day after the branches were decapped and defoliated, 80% of the axillary buds of the branches obtained through the above steps all germin...

Embodiment 2

[0028] The method for promoting shoots of custard apples comprises the following steps:

[0029] 1. Select the branches drawn in the current year and use branch scissors to cut off the top 5cm branches (remove the top). Then remove all or part of the leaves of the custard apple branches that have been removed.

[0030] 2. After the branches have been decapped and defoliated, quickly spray the calcium chloride solution with a mass fraction of 3%, until the axillary buds are fully wetted.

[0031] 3. After spraying the calcium chloride solution for 2 hours, spray 15mg / L of heterocyclic urea cytokinin until the axillary buds are fully wetted again.

[0032] 4. Repeat steps 2 and 3 on the 3rd and 5th days after the branches are topped and defoliated to promote the germination of axillary buds and form new shoots.

[0033] The results showed that: on the 8th day after the branches were decapped and defoliated, 85% of the axillary buds of the branches obtained through the above st...

Abstract

The invention relates to the fruit tree cultivation technical field, and specifically discloses an Annona squamosa L shoot promoting method comprising the following steps: selecting current year sprouted branches, topping the branches, and removing all or partial blades of the branch after topping; spraying calcium chloride solution with mass fraction of 3-5%; spraying cytokinin 1-2 hours later; repeating the said steps for 2-3 times in one week after branch topping and defoliation so as to promote axillalry bud germination, and forming new shoot. The method is very simple, can basically solve the problems that partial axillalry bud cannot germinate into new shoot in conventional artificial processing. The branches processed by the method can realize 85% axillalry bud germination rate 8days after branch topping and defoliation, and 78% of germination axillalry bud can grow new shoots 30 days after treatment.

Description

technical field [0001] The invention relates to the technical field of fruit tree cultivation, and more particularly relates to a method suitable for promoting shoots of custard apples. Background technique [0002] cherimoya ( Annonasquamosa L.) Also known as Ringo, sweet lychee, custard fruit, sweet fruit, belongs to the Annonaceae ( Annonaceae ) is a small deciduous tree, which is a rare fruit in tropical and subtropical regions. It is planted in several provinces in southern my country, especially in Guangdong, Hainan, Fujian, Taiwan and other provinces. The custard apple has a unique flavor, is sweet and refreshing, rich in nutrition, rich in Vc, and low in fat. It has the functions of beautifying the spleen and stomach, enhancing immunity, and anti-cancer. The majority of consumers of all ages. [0003] The buds of custard apple are compound buds, and the axillary buds are embedded by petioles. If the leaves do not fall off, the axillary buds will generally not ge...
