Description

Methods are known for the eradication of cuttings of cultivated bony and other difficult-to-root tree species by immersing arcuately wilted drooping branches or a bole-tree cultivated in the soil.

In contrast to the well-known, with and, the simplification of the bruising technique, a method has been proposed, according to which, instead of removing the annular portion of the cortex on the root branch, the epidermis is removed from the cortex area by pulling the root branch between the fingers.

FIG. Figure 1 shows a method for bruise bruising, the initial stage; in fig. 2 the same. final stage.

To root the cuttings (Fig. 1L), it is necessary to dig under the shoot a weave with a depth of 8-10 cm and a length sufficient to stack the last year's growth in the horizontal direction (Fig. 1B). From each shoot of a new growth, remove all but 5-6 apical leaves. From each shoot, it is necessary to remove the epidermis 3-4 cm from the base of the shoot tips. To remove the epidermis, hold the base of the shoot with your left hand, squeeze it tightly with the thumb and forefinger of your right hand and stretch it for 3 -4 cm twice in the upward direction. The bark of the shoot then becomes wet. After that, bend the shoot into the plant and, holding each shoot separately in an upright position, sprinkle it with soil to the level of the leaves removed. Then the soil around the sprinkled shoots should be tamped down, zamulgirovat and in the future every 15 days to weed pristvolnyh circles.

As the annual shoots of the stem growth grows (Fig. 1B), it is possible to switch to laying and peeling of these shoots.

In the spring of next year, the process of root formation begins in the shoots dug into the soil.

The apical part gives rise to 3–4 or sometimes more shoots, one of which must be left to form the crown (Fig. 2A), and the rest (Fig. 2B) can be used to root the second generation of beads.

In autumn, at the beginning of October, well-lined cuttings with lignified root system can be dug out. Bored and dredged dug out and separated from the uterus tree should be buried to protect it from draining.

The separation of barked cuttings from the stem should be carried out after digging into the ring (Fig. 2 B) with garden shears or a knife.

The seedlings obtained in this way are planted in a permanent place - in the garden.

Research Institute of Horticulture. I. V. Michurin and Central Technical Laboratory named after I. V. Michurin notes the practical usefulness of the proposed method, especially the creation of varietal orchards in the harsh conditions of Siberia, and one's own-rooted trees can easily recover and bear fruit in the event of their death.

Subject invention

The method of nurturing the cuttings of cultivated blon and other difficult-to-root tree species by submerging arcuately wilted drooping branches or stem growth in the soil, characterized in that, in order to simplify the bruising technique, instead of removing the ring bark section, the epidermis is removed from the area of the cortex by pulling the root branch between the fingers over a distance of 3-4 cm.
