Embodiment 1

[0023] In Guangxi, where mangoes are suitable for growing, select 5-6-year-old mangoes that are propagated by seeds. The annual growth of the tree height is greater than 2.0m, and the annual growth of the rice diameter is greater than 1.5cm. ; The trunk is complete, the crown is large, and the growth is vigorous; the tree is healthy, free from diseases and insect pests, and free from wind damage; 5-year-old trees with a branch point height of 2.5m or more are used for greening. Excellent varieties of mango are used as ear picking mother plants.

[0024] In the spring when the rain is sufficient and the temperature rises, the trunk of the mother plant for ear picking is about 30cm above the ground, and the circumcision is 2 / 3 of the trunk circumference, 5-6cm wide, and deep to the phloem. Spray concentration at the circumcision. 1.0mg•L -1 Cytokinin 6-BA to promote germination.

[0025] From March to June, the sprouted strips obtained after ring cutting grow to 40-60 cm, grow ...

Abstract

The invention discloses an asexual propagation method for a good mangifera indica variety for greening. The method comprises the procedures of maternal plant selecting, propagating material acquiring, cutting collecting, cutting pruning, rooting solution preparing, cuttage and post-cuttage management, i.e., selecting the good mangifera indica variety for greening as cutting collecting maternal plants, girdling the cutting collecting maternal plants to obtain bud sticks which have the length of 40cm to 60cm and are robust in growth and free from plant diseases and insect pests, collecting and pruning the bud sticks, then, soaking the bud sticks in a rooting solution, then, carrying out cuttage, and then, carrying out post-cuttage management, thereby obtaining mangifera indica cuttage seedlings for greening. According to the asexual propagation method for the good mangifera indica variety for greening, variety screening is carried out according to selective breeding requirements of garden tree species, the excellent mangifera indica variety applicable to landscaping cultivation is screened out, the traditional purposeless and unordered greening mangifera indica breeding cultivation habit is changed, the commodity value of greening mangifera indica is increased, and the market demands are met.

Description

technical field [0001] The invention belongs to the technical field of plant asexual reproduction, and relates to a method for asexual reproduction of fine mango varieties for greening. Background technique [0002] mango( Mangifera indica L. ) is an evergreen tree belonging to the Anacardiaceae mango family. It is native to the border between Assam, India and Myanmar. It is widely cultivated in southern my country and is one of the famous tropical fruits. The mango tree has a tall crown, dense branches and leaves, dark green leaves, and a lifespan of hundreds of years. Its wide leaves have obvious functions of blocking, filtering and adsorbing dust, and have significant functions in urban greening and beautification and air purification. Since the late last century, mangoes have been widely planted in urban roads, squares, residential areas, factories, and parks in southern cities in my country. Due to their good growth performance and unique landscape effects, they have be...
