Propagation method for using single-bud short tamarix to cut containerized seedlings

A cutting container and cutting propagation technology, which is applied to the field of propagation of camellia single-bud and short-ear cutting container seedlings, can solve the problems of restricting the scale and quality of rapid propagation of Camellia oleifera varieties, failing to meet the needs of high-quality seedlings, and poor transplanting effects. The cultivation cycle is short, the operation is simple, and the effect of improving comprehensive benefits

Problems solved by technology

However, the conventional cutting method that has been used in my country until now has low reproduction coefficient, slow multiplication, and poor transplanting effect.
These problems have seriously restricted the scale and quality of the rapid propagation of Camellia oleifera, making it impossible to meet the demand for high-quality seedlings in the development of Camellia oleifera industry

example 1

[0034] Example 1: In late May 2006, the excellent clones of camellia oleifera, which had passed the national forest tree variety examination and approval, were used as propagation materials. The cuttings were semi-lignified spring shoots, and 20,000 short spikes with one bud and one leaf were cut into 20,000 short spikes, which were treated with rooting agents for cutting . The container is a white non-toxic plastic film bag of 8cm×12cm. The cutting substrate is mixed with fresh river sand and clean fresh yellow heart soil according to the following mass percentages: 20% river sand, 80% yellow heart soil, and 75% shading degree of the awning. 20 days after the cutting, the rooting situation was investigated, the average rooting time was 28 days, and the average rooting rate reached 92.4%.

example 2

[0035] Example 2: In September 2006, clean and fresh pure yellow heart soil was used as the cutting substrate, and the lignified summer shoots of the high-quality Camellia oleifera clone were cut into 1.5cm-2cm short spikes containing 1 bud and 1 leaf, and the cut cuttings Sterilized with 0.1% potassium permanganate and treated with rooting promoter (100mg / L NAA+300mg / LABT6#rooting powder) and cuttages, the insertion depth should not cover the buds and leaves, and slightly compact the base of the panicle after cutting , and water thoroughly to ensure that the cuttings are in close contact with the substrate; the shading degree of the shade shed is 80%, the number of cuttings is 1500, and the container specifications are the same as in Example 1. The management during the period from cutting to rooting and survival mainly focuses on moisturizing, foliar topdressing and disease control. According to the survey in June 2007, the survival rate was 93.6%, and the nursery rate was 8...

Abstract

The invention relates to a propagation method for using a single-bud short tamarix to cut containerized seedlings. The propagation method comprises the main operating steps of: firstly establishing pergolas, preparing cutting containers, cutting matrixes and cutting beds of the containers, then carrying out cutting propagation operation, selecting the branches of the middle-upper part of the periphery of the middle-old age excellent clonal crown as cuttings, carrying out cutting in summer or autumn, doing well in work of weeding, fertilizing, moisturizing and prevention of pests. The propagation method has short culturing period, generally needs only 10 to 12 months, has simple operation, high propagation coefficients, fast propagation expansion and good transplanting effect, also can effectively reduce the loss of cutting propagation materials, and improve comprehensive benefit of industrial development of good seeds of the oil tea.

Description

technical field [0001] The invention relates to a method for propagating forest trees, in particular to a method for propagating camellia single-bud short-ear cuttage container seedlings. Background technique [0002] Camellia oleifera is a unique woody edible oil tree species in my country. Because Camellia oleifera cultivation is far away from urban pollution, tea oil extracted from seeds is a good natural green food. It is the most reasonable fatty acid composition in edible oils and fats. Long-term consumption can reduce harmful cholesterol in serum, and has the effect of preventing and treating arteriosclerosis. Atherosclerosis, coronary heart disease, hypertension and other cardiovascular and cerebrovascular diseases, it is a high-grade edible oil that integrates safety, high quality, health care and other functions. With the vigorous development of Camellia oleifera industry and the growing demand for Camellia oleifera raw material forest bases for high-quality camel...
