Method for rapidly propagating big camphor trees by layering high stems

Abstract

The invention provides a method for rapidly propagating big camphor trees by layering high stems, which relates to a plant propagation method, in particular to a propagation method for camphor trees. The method comprises: a, choosing a seedling female parent; b, choosing a propagation cultivation place; c, choosing propagation time; d, choosing a good female parent and annularly cutting a gap which is 5 to 10 centimeters in a position 50 centimeters from ground; e, smearing disinfection solution and rooting liquid on bark in an annularly cut part, wrapping the gap in 1 to 5 kilograms of filling matrix, binding the annularly cut part tight with plastic cloth and packaging ropes and wrapping up to form a drum-shaped bag; and f, performing planting until white roots grow two months after annular cutting, turn yellow after eight months and grow to fill in the bag. Big trees produced by the propagation method can have two-thirds time of growth cycle shortened compared with normally sown and cultivated seedlings, and are developed in root systems, exuberant in growth vigor and capable of repeated regeneration and utilization.

Description

technical field [0001] The invention relates to a plant propagation method, in particular to a camphor tree propagation method. Background technique [0002] Cinnamomum Camphora (L) Presl is a plant of the genus Lauraceae, an evergreen tree. It is a representative tree species of subtropical evergreen broad-leaved forests. There are few natural forests. wood one. It is mainly distributed sporadically in the range of 1600m-1800m above sea level in Manxingliang Reserve, and there are few wild resources. Cinnamomum camphora has a long history of cultivation. It has beautiful tree posture, vigorous and free and easy shape, luxuriant branches and leaves, and thick shade everywhere. It is more and more widely used in urban greening and has very broad development prospects. The traditional propagation of camphor is based on sowing. In this traditional sowing method, it takes at least seven years to cultivate a camphor tree with a diameter of 8 cm, which can be used as a green see...

Problems solved by technology

The traditional propagation of camphor is based on sowing. In this traditional sowing method, it takes at least seven years to cultivate a camphor tree with a diameter of 8 cm, which can be used as a green seedling. It takes fifteen years to grow a tree with a diameter of 20 cm. Years, so the traditional cultivation method has the disadvantages of long growth cycle and slow effect, and when excavating, the size of the soil ball should reach 8-10 times the diameter at breast height, and special needs require larger, and sometimes even require a crown width or In this way, there are problems such as difficult transportation and handling, high transportation costs, large floor area, difficult management and maintenance, and low survival rate.
