The method of privet to graft gold leaf privet

The gold leaf privet is generally balled on the ground. In order to improve the ornamental quality, the golden privet ball can be raised by means of grafting. After the experiment, the author used the big leaf privet as the rootstock to be successful.

Grafting time: in the autumn, the weather was cooler and the plants were grafted before the second growing season.

Selection of grafting: Choose robust and disease-free high-drying Ligustrum lucidum plants, and select 4 to 5 shoots per plant as rootstock. In the thick branches of the golden leaf privet without pests and diseases, well-developed and full bud eyes were selected for the shoots. Take a shield connection, with xylem buds. After the connection is completed, the entire wound is wrapped with a layer of film to prevent infection. In general, each big-leaf eucalyptus is grafted with 8 to 10 buds.

Management: After the completion of grafting, normal management, about one month or so the wound began to heal. After pouring spring water at the beginning of April of the following year, the mulched film was removed and the branches of privet were removed at 2 cm above the grafted shoots. A few days later, the buds of viable Ligustrum lucidum began to germinate. When the shoots grow to about 10 cm, the shoots start with 2 to 3 cm.

The Ligustrum lucidum and the gold leaf privet belong to the genus Oleaceae and Ligustrum. The former is a very good green tree, because of its popularity, it is often not valued. The latter belong to the color tree species and have been widely used by people in recent years. Because the gold leaf privet is a shrub species, it limits its practicality. In order to expand the greening function of the two, the author has achieved this goal through the method of taking advantage of each other's heights. Proceed as follows:

In the spring, branches or buds can be used (the sap has flown, and it is best before germination). The big-leaf privet of 3 cm to 4 cm in diameter was used as the rootstock, and the primrose gold leaf was used as the scion. First, select the height of the rootstock and the angle of the branches. On the inside of the base of the rootstock branch, a blade with a length of about 2 cm is cut with a knife, and the knife edge is just the best for the xylem. The scion can be 3 cm to 5 cm long and is cut into 2 cm positive wedges with a knife. The blade of the rootstock is slightly longer than that of the scion. Then, quickly and accurately align the formation of the two, such as the root blade is too wide, you can juxtapose two scions. Then, wrap it up from the lower part of the cutting edge of the rootstock with a moderately stretchable plastic strip. It can be used with a large force when wrapping the joint between the two, and when it is wrapped around the upper part of the scion with no knife edge, it can be evenly wrapped around the rootstock. At this time, be sure to cling the scion tightly, otherwise the scion is easy to dry or not heal. After grafting is completed, some rootstock branches and leaves can be properly removed. This work can also be done before grafting.

In the spring, shoot with a knife. Cut a knife with a length of about 2 cm in the appropriate position on the rootstock. When cutting the scion, bring a certain xylem (not too thick). Then align the two layers and use the plastic strip from the bottom up. Wrap up. When wrapped around buds, use lighter force to avoid injury. Dew or not, look at the weather.

A week or so can tell you whether you survive or not. If you fail, you can come back and succeed in grafting. You can remove the plastic strips and then gently wrap them around. The branches may not be entangled in the upper part, and the buds may expose the buds to facilitate germination. Before the scions have sprouted, do not cut all the branches and leaves of the rootstock, otherwise it will cause the rootstock to "stuck" or even die. At this time, the leaves of the rootstock can be left 1/3 strong point to maintain the physiological balance of the crown and the root system. When the scion's buds grow to 1 cm to 2 cm, all branches of the rootstock can be cut off and plastic strips removed. In the later management, the sprout on the rootstock was mainly removed. The buds on the rootstock stems can remain part of the rootstock, controlling their growth through heading, and laying the foundation for future styling. The buds around the roots and scion should be removed to avoid competing for nutrition and disturbing the tree shape.

The affinity between the two is strong, the knife edge heals well, and the grafted seedlings thrive. Such as water and fertilizer to keep up, properly managed, two years of the crown of up to 2 meters, golden branches naturally drooping. The shoots sprouted in the lower part of the rootstock can be artificially shaped, or flat, or spherical.

Enzyme, known as enzyme, refers to a polymer substance having biocatalytic functionality. In the catalytic reaction system an enzyme, the reactant molecules are known as substrates, enzyme substrates by catalytic conversion to another molecule. Almost all cellular activity of enzymes involved in the process are required to improve efficiency. Similar to other non-biological catalysts, enzymes chemical reactions by lowering the activation energy to accelerate the rate of the reaction, most of the enzyme catalyzed reaction rate can be increased a million times; in fact, the enzyme is to provide an activation energy needs than another low way, so that more particles to have less than the activation energy of the reaction kinetic energy, thus speeding up the reaction rate. Enzyme as a catalyst, in itself is not consumed during the reaction, it does not affect the chemical equilibrium reactions. Positive enzyme catalysis, but also a negative catalytic effect, not only to accelerate the reaction rate, but also to reduce the reaction rate. And other non-living catalysts is different, having a high degree of specificity of enzyme, only a catalytic reaction or produce a particular specific configuration.
