Embodiment 1

[0024] (1) Experimental materials

[0025] After the leaves of the annual hickory seedlings fall, cut off the branches, remove the young shoots at the top of the branches, and select the middle (diameter 0.5-0.9cm) and lower (diameter 0.9-1.2cm) branches. Then cut into short branches with a length of 12cm.

[0026] (2) Cutting method of thin shell hickory

[0027] Cutting method Ⅰ (there is a temperature difference between the incision in the branch form and the temperature of the external environment)

[0028] Spread electric heating wires on the bottom of the seedbed, then mix the four substrates of 40% perlite, 40% peat soil, 15% river sand, and 5% vermiculite in proportion, and spread them on the heating wires with a thickness of 10cm. Then insert the lower end of the branch form (cutting place) into the substrate, close to the heating wire, and the row spacing between plants is 10cm. The temperature at the cut end of the branch and the bottom of the substrate is contro...

Abstract

The invention discloses an apocarya hardwood cutting seedling raising method. The method comprises the steps of selecting a 12cm long middle section twig and a 12cm long lower section twig of an annual apocarya seedling, soaking the trimmed twigs in a solution of phytohormone IBA (Indolebutyric Acid) or NAA (Naphthaleneacetic Acid) for 4 hours, inserting the morphological lower ends of the twigs into a matrix, laying a heating wire at the bottom of the matrix, and controlling the temperature difference between the bottom of the matrix and the outside temperature at 15 DEG C approximately, and the water content at 30% approximately. The rooting rate is counted after 60 days, and reaches above 81%. The rooting rates of a single phytohormone treatment method or a single temperature difference method are both 0%. The method effectively realizes the apocarya cutting seedling raising; seedling raising approaches of apocarya are widened; and powerful technical support is provided for the rapid propagation and industrialization of the apocarya seedlings.

Description

technical field [0001] The invention belongs to the field of fruit tree and forest tree breeding, and relates to a method for raising seedlings by cutting hard branches of hickory with thin shells. Background technique [0002] Thin-shelled hickory, also known as American hickory, is a species of Juglandaceae and Hickory. Native to the United States and Mexico, it is one of the most important oil-bearing dried fruit tree species in the world. Its shell is thin and easy to peel, its kernels are thick and fleshy, and it has a delicious taste and high nutritional value. The trunk is straight, the tree shape is beautiful, the roots are deep and the leaves are luxuriant, and it is an excellent tree species for greening and gardening around. At the same time, the wood is tough and dense, with dark red heartwood, yellow-white sapwood, high elasticity, and is not easy to deform and crack. It is an excellent timber tree species for construction and high-end furniture. Therefore, pe...
