Embodiment 1

[0022] A method for raising seedlings from branch branches of macadamia nuts, which mainly comprises the following steps:

[0023] (1) Branch selection. In early March, choose 2-3 year old branches on a 6-year-old macadamia nut tree with good quality, with robust branches and no pests and diseases; branches with a diameter of 2-3cm are usually selected.

[0024] (2) For branching treatment, the selected branches are girdled at a distance of 15-20cm from the branch bifurcation, the width of the phloem of the girdling is 2.0-4.0 cm, and the depth is up to the xylem, and the ring is smeared with a root-promoting medicinal liquid composition. Peel the mouth for a circle, and then tie it to the girdling place with a moist substrate. The moist substrate is a uniform mixture of cassava peel, peat, and fired soil with a mass ratio of 1:1:1; the outside is wrapped tightly with film and tied with ropes at both ends.

[0025] The medicinal liquid composition is prepared in advance, and 1...

Embodiment 2

[0032] A method for raising seedlings from branch branches of macadamia nuts, which mainly comprises the following steps:

[0033] (1) Branch selection, in mid-June, select 100 branches with 2-3 years old, strong branches and no pests and diseases on the 5-year-old macadamia mother tree with good quality; usually choose branches with a diameter of 2~3cm.

[0034] (2) Branching treatment, the selected branches are girdled at a distance of 15-20 cm from the branch bifurcation, the phloem width of the girdling is 2.0-4.0 cm, and the depth reaches the xylem, and the ring is smeared with a root-promoting medicinal liquid composition Peel the mouth for a circle, and then tie it to the girdling place with a moist substrate. The moist substrate is a uniform mixture of cassava peel, peat, and fired soil with a mass ratio of 1:1:1; the outside is wrapped tightly with film and tied with ropes at both ends.

Embodiment 3

[0042] A method for raising seedlings from branch branches of macadamia nuts, which mainly comprises the following steps:

[0043] (1) Branch selection, in mid-September, select 2-3 year old branches on the 6-year-old macadamia mother tree with good quality, with robust branches and no pests and diseases; branches with a diameter of 2~3cm are usually selected.

[0044] (2) Branching treatment, the selected branches are girdled at a distance of 15-20 cm from the branch bifurcation, the phloem width of the girdling is 2.0-4.0 cm, and the depth reaches the xylem, and the ring is smeared with a root-promoting medicinal liquid composition Peel the mouth for a circle, and then tie it to the girdling place with a moist substrate. The moist substrate is a uniform mixture of cassava peel, peat, and fired soil with a mass ratio of 1:1:1; the outside is wrapped tightly with film and tied with ropes at both ends.

Abstract

The invention discloses a macadamia integrifolia branching-after-topping seedling cultivation method. The method includes the steps that first, a disease and insect pest-free branch with a robust branch trunk is selected from a macadamia integrifolia mother tree with excellent quality; then, girdling is carried out at the position 15-20 cm away from a branch fork, a liquid medical combination used for promoting root growth is smeared on a girdling opening by a circle, a moist matrix is then attached to the girdling position, the outside of the girdling position is tightly wrapped with a thin film, and the two ends of the girdling position are bundled through ropes; after 25-35 days when branching-after-topping treatment is carried out, a diluted ethephon solution is added into a thin film packet; after three months, root systems are growth gradually at the girdling opening, and after 90-120 days when branching-after-topping treatment is carried out, branch half-shearing treatment is conducted at the lower end of the rope bundled position; after 20-40 days when the branch half-shearing treatment is conducted, the branch is sheared at the half-shearing position, so that heeling-in transplantation is performed. The macadamia integrifolia branching-after-topping seedling cultivation method solves the problem that a traditional grafting method is low in rate of survival, and is simple, easy to operate, short in seedling cultivation cycle and high in rate of survival.

Description

technical field [0001] The invention relates to the technical field of plant seedling raising, in particular to a method for raising plant seedlings by branching. Background technique [0002] Macadamia integrifolia, also known as Queensland chestnut, macadamia, etc. Its seeds are rich in unsaturated fatty acids, proteins, vitamins, etc., with high nutritional value and unique flavor, so they are known as the "Queen of Dried Fruits". In the international market has been in a state of short supply. Planting macadamia nuts has the advantages of simple management, low investment and high benefits, and is very popular among fruit farmers. [0003] Macadamia nuts are generally propagated by grafting. The use of traditional grafting technology to breed macadamia seedlings has three defects: First, the traditional grafting method has a low survival rate, generally only about 50%. Second, the grafting time range is narrow, generally only spring and autumn can be selected. Third...
