Macadamia Nut Branch Seedling Raising Method

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 planting seedlings by branching. Background technique [0002] Macadamia nuts (Macadamiaintegrifolia), also known as Queensland chestnuts, macadamia nuts, etc. The seeds are rich in unsaturated fatty acids, proteins, vitamins, etc., with high nutritional value and unique flavor. They are known as the "Queen of Dried Fruits". It has been in short supply in the international market. Planting macadamia nuts has the advantages of simple management, low investment, and high efficiency, and is deeply loved by fruit farmers. [0003] Macadamia is generally reproduced by grafting. The use of traditional grafting techniques to breed macadamia seedlings has three disadvantages: 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,...
