(54) METHOD FOR VEGETATIVE REPRODUCTION OF BUSHES

I

The invention relates to forestry and can be used for the vegetative propagation of shrubs, mainly walnut.

There are known methods for breeding ore- 5 heddy shrubs by offspring (young), by the Dalem method (wire crossing shoots and hilling them), by dividing the bushes of the p ..

The disadvantage of these α-methods is their complexity, and the developed methods of green grafting do not yet give the desired results both in rooting of the cuttings and in the yield of planting material. 15

There is a known method of breeding shrubs with horizontal otvodkgili 2. It is used for rooting shoots that are not separated from the parent plant. It allows for the reproduction of difficult rooting plants.

The disadvantage of this method is to obtain cuttings as a very expensive breeding method, because ../ for uterine plants you have to deduce a significant area and almost all the work is done manually. This method is more often used in amateur practice and rarely for industrial breeding of woody plants. thirty

The purpose of the invention is to increase the multiplication factor and the quality of the raw material.

. The goal is achieved by separating the green branches from the parent plant with the preservation of the annular flow and planted in the substrate in a horizontal position.

The proposed method of varietal vegetative reproduction of shrubs, such as hazelnuts and hazel, which do not produce root shoots, is as follows.

During the period of the most active growth, the branches of the current growth of unlimited length are torn off the uterine bushes of the hazel grove with the necessary preservation of the annular influx and leaves, then placed in a solution of growth stimulants for 12–16 hours air humidity . The branches with whole leaves are planted horizontally into the substrate, while the entire branch is covered with the mechhed substrate (interstitial) so that the sweet cherry leaf, where the new sweets will be laid, will not be filled. The leaves remain on the surface, continue to assimilate, and after about 20–25 days after planting the branches, at the ends of their several high annular flow, roots begin to form. Roots are also formed over the entire lower part of the branch, most often in the leafy ties of the ax branch. Two to three months after the branches are planted in the closed ground of the fog-forming plant, the length of the individual roots reaches 20–30 cm or forms a shorter, but thick root flake.

In the spring of next year, the vegetation of the base of young shoots grown up to 5-10 cm in height, is curled with earth in order to receive well-established plants from them in the autumn, in order to get branched out, in. A croned annual plant, suitable for realization as a two-year-old, should be squeezed by growing shoots at a height of 20-30 cm. After two weeks, 3-5 side branches will begin to germinate on plants with pinned tops. Thus, from one whole branch of hazel by the end of the 2nd year of vegetation, from 5 to 10 good seedlings can be obtained, suitable for planting on industrial plantations.

The use of the proposed method for vegetative propagation of a marrow allows to reduce the time

growing planting material up to two years; to increase its quality, to achieve a high multiplication factor (up to 5-10), to reduce the cost of seedlings.
