Description

The invention relates to breeding, in particular to methods for propagating vegetative rootstocks.

The purpose of the invention is to reduce the labor intensity in the separation of growth and improve the quality of planting material.

The drawing shows the liquor tank before the separation of rooted layers.

The method of propagation of vegetative rootstocks by layering on the mother liquor is carried out as follows.

After appropriate preparation of the soil along the length of the row, maturing plants 1 are alternately planted in a trench alternately, for example, at regular intervals, at an angle to the ground and to the direction of the row (Fig. 1). In the autumn of the first year, plants 1 and their growth 2 are pinned in the direction of their growth, tightly pressed to the ground, with growth 2 being directed parallel to the row. Then the plants 1 are covered on top with a mesh 3 with rigid cells. 4 diameters 4-5 mm. In the summer of the second year, as the resulting increment of 2 increases, the whole series is tucked up, and in the autumn the cuttings are separated.

Example. The tests were carried out by setting the field. experiments and laboratory analyzes of soil and plants according to general methods. experiments with p. fruit plants. Field experiments were conducted during 1983-1985. annually. The soil of the experimental plot was represented by chernozem carbonate 1m t yellowish loamy on light loam. Stocks of М М 106, about 60 cm long, were planted in a materiel on a plot of 0.5 hectares into pre-cut furrows 25-30 cm deep and 25-30 cm wide at the top, and 10-15 cm below at a length of one and two the other side of the row is 10D at an angle to its direction so that 40 cm of the length of the basement remains above the surface of the soil. The planting was carried out at the rate of 16,600 plants per 1 ha according to the scheme 140x40 cm. The distance between the adjacent plants on one side of the row was 40 cm, and those located in opposite sides were 20 cm.

In the fall (15–25 oct. Br), the originally planted plants 1 were pinned tight to the ground. From April to October of the first year, a growth of 2 to 50-65 cm long formed on the originally planted plant. Usually there are 3-5 shoots per each individual plant.

On October 15-20, the first year, the plants were transplanted to the ground, and the growth of the current year was directed along their growth in parallel to the line, pressing down firmly on the ground. Usually, the growth always laid in such a way overlapped the iodine laid in front with an angle to the direction of the row and the plant; parallel rows (3-5) were formed with a distance of 8–15 cm along the length of the whole row.

That increase, which could not be pinned tight to the ground due to their vertical growth, was cut with the remaining 2-3 holes. And after all this, the plants were laid on top of an equally-dimensionally laid-up flower in the same way. They laid a metal mesh of 3 dimensions 50X200 cm with a diameter of 2-9 mm. The growth, falling into a separate cell, initially grew freely, then a rigid grid cell restricted plant growth in diameter, thereby gradually making it difficult for nutrients to enter the soil to grow and develop the land part of the plant. This, in turn, caused the plant to respond in the ground part. It began to prematurely form the roots above the net and on the part of the plant that was heaped up. Thereby they reached a certain height along the whole length of the row. Due to the fact that the wood, the cuttings slam into the rigid cell as it thickens, forming a wedge-shaped section, the cuttings are easier to separate. This technique is provided without the use of cutting tools and is easily mechanized.

In tab. Figure I shows the effect of the diameter of the grid cells on the productivity of vegetation stands.

The results of the experiments (see Table 1) showed that a higher yield and better quality of cuttings are obtained when changing the mesh with cell diameters of 4-5 mm. A cell diameter of 3 mm or less contributes to the fact that disconnecting the root system in the work on shaping the cutting starts too early when the plant is not yet sufficiently strengthened. A cell diameter of 6 mm or more also gives undesirable results due to the fact that upon reaching such a diameter, the wood ages and the deadline for the formation of roots above the net is missed.

The use of the grid forms the layering in the lower part in the form of a cone, which allows reducing labor costs for separation by 2 times in comparison with known methods.

The tests were carried out on the stock M 27, M 9, M 26, which were planted under the same conditions as the stock MM 106.

To compare the proposed method of separating the layering on a mat with the known, according to the well-known method, the stocks M M 106, M 27, M 9, M 26 were planted in separate areas of 0.25 hectares according to the exact same technology as the proposed one. This method, but only for a certain period, was not covered on top with a metal grid with a cell diameter of 5 mm (see Table 2).

Output and quality are shown in table 2.

The propagation of rootstocks on the proposed method makes it possible to increase the yield.

improve the quality of cuttings and significantly reduce the cost of their separation. The proposed method of propagation of rootstocks using a metal mesh provides 100% root formation above the mesh point, resulting in an increase in the output of first-class cuttings, as well as the creation of a solid root system along the width and length of the mother liquor thus created; maintaining the head of uterine bushes at the same level, as a result of which the durability of the mother liquor as a whole increases and the possibility of mechanization of all processes from planting to separation of the layers.
