A kind of cutting propagation method of oak oak

Abstract

The invention relates to a cutting propagation method for quercus acutissima. The method includes: performing seedling-stage processing, processing a cutting bed, setting cutting slip collecting time,shearing cutting slips, processing with cuttage chemicals, setting cuttage density and depth, setting cutting-bed temperature and humidity, performing management after cuttage and transplanting. Themethod is simple to operate, short in seedling culture cycle, high in rooting rate and survival rate, low in chemical use quantity, environmentally friendly, low in cost, non-strict in cutting slip length requirement, many in available branches, and promising in market application prospect in the genetic improvement acceleration and improved-variety expanding propagation of the quercus acutissima.

Description

technical field

[0001] The invention belongs to the technical field of plant vegetative propagation, and in particular relates to a cutting propagation method of oak green branches. Background technique

[0002] Oak oak ( Quercus acutissima Carr .), Fagaceae (Fagaceae), Quercus ( Quercus Linn.), a deciduous tree, is a common deciduous tree species in warm temperate mountains. leaves as tussah ( Antheraea pernyi Guérin-Méneville) high-quality feed, widely used in Liaoning, Shandong, Hebei and other provinces.

[0003] The wood is a ring-porous wood with hard material, straight or oblique texture, and is resistant to decay. It is used for sleepers, pit logs, bridges, floors, etc.; the seeds can be used as feed and industrial starch; the shells and bark can be used to extract tannins. Segments and sawdust can be used to produce edible fungi and fuel. Oak Quercus is a widely distributed species in South China, and is also distributed in Central China, Yunnan, Guangxi and...

Embodiment 1

[0026] A method for propagating by cuttings of Quercus japonica green branches, comprising the following steps:

[0027] 1. Seedling pretreatment: Select 2-year-old high-quality saplings in the ear-picking nursery built with good provenance. Before the sap germinates in spring, cut off the upper branches from the root neck. Seedling. 4 days before the cutting, in the selected area of ​​the ear-picking garden, nail stakes on the side of the ridge of the seedlings with a distance of 1.5m, and tie the sunshade net to the stakes to shade 70%.

[0028] 2. Slotting bed treatment: Slotting beds are installed in the greenhouse of Sericulture Science Research Institute of Liaoning Province. Each slotting bed is 8m long, 0.9m wide, 13cm deep, and 55cm high. Build an arch frame on the slotting bed with a height of 60cm. Then cover the plastic film on the arch frame. Lay the cutting matrix in the slotting bed, the matrix is ​​perlite, the particle size is 2~5mm, and the laying thicknes...
