(54) METHOD FOR STRATIFICATION OF GRAPES

We go for the convenience of the descent of water. Particularly well. The film is pressed into the corners of the crate so that it does not fall off after the inoculation is laid.

Vaccinations are placed in a box in a strictly g vertical position so that each of them touches the film. In the standard box, put 1050-1250 vaccinations.

After grafting, the boxes cover the moistened film with transport pieces (1.2x1.5 m) of 1.3 moist films and transfer them to stratification chambers.

In the chambers, the vaccination boxes are placed at a distance of 23 cm from each other, which is necessary for its natural aeration. After installing a series of 9-11 shixf. Transport films are removed from them and covered-from a common film with a 1: 4 m wide film in such a way as to cover the upper part of a protective film; The film can be used as pony-ethylene, and popivinyl chloride.

In stratification chambers, boxes are immediately filled with water in a layer of 3-5 cm. Stratification is carried out at a temperature of 2S

25-27 С and, air humidity in the chamber 8О-85%. After a few hours, water vapor condenses on the bottom of the covering film and covers with different or larger drops of water.

Vaccination care should be directed to ensure that vaccinations do not dry out during aeration, otherwise callus will not form and the plant will not grow together with graft, and to prevent over-moistening that promotes the formation of mold and death, vaccinations.

The water level in the box is monitored daily, and, if necessary, water 5 40 will become olive. After 5-7 days, water is exchanged for the first time, the second time it is changed to the end of the stratification.

. Systematically monitor the content of condensed WATER., Sub-film. 45 If the water droplets under the film are large and draining, they can cause the waterlogging of vaccinations, therefore, it is necessary to increase the rate of natural arayia, the vaccinations should be less covered or ventilated by 50. removing the total coating film. The film can be removed at 5-1 O mn and even up to one hour, depending on the humidity in the atmosphere and in the surrounding atmosphere. If the logod is dry, the air is short-lived; in wet, damp weather, you can remove the film at an AO-60 min.

If under the water of a Mapo film, the vaccinations should be better covered, sprayed with water on the underside of the coating film.

It is necessary to carefully monitor the state of the vaccines themselves. When the first signs appear, molds should be further ventilated by removing the total coating film or ventilated and purged.

Blow vaccinations should be short-lived, no more than 20-30 seconds, so as not to dry them, should be blown only from above, and not with. sides so as not to dry the copula pion slices.

In order to determine whether the vaccinations have dried out, 1-2 u are taken for analysis. they separate the stock from the graft, and pay attention to the copulation cuts, if they are wet grafts have not dried. It is better to update the cuts as a stock, and on the graft; This is done in the same way as in the determination of soaking: if there is water on the center, the vaccinations have not dried up.

Usually, vaccination dries up if there is condensed water under the Mapo film or there is none at all.

To prevent vaccinations from drying out, they should be sprayed with water, it is better to dig them, move the chic, reduce the speed of aeration and remove water vapor from the crate ..:

After 10-11 days, the stratification ends at almost all; healthy inoculations form a circular callus at the adhesion site, the buds on the scaffold swell or start to grow. The roots of the graft are not formed. .

On the last day of stratification, cover films are removed for 3-4 hours. On the next {day, the coating films are removed for 8–9 hours and, after this, the inoculations are left open for days in a stratification chamber to undergo partial hardening.

Then water is drained from the boxers and transferred to the hardening compartment and fresh water is poured in when quenched.

Vaccinations that have passed through stratification during natural aeration and subsequent subsequent quenching are exiting. into the ground, without covering the place of adhesion with earths, without waxing and with good agrotechnology in shkopka provide an extremely high output of per-grape seedlings.

Claims (1)

Claims: A method of grafting a graft graft, including immersing the basal tips of grafts 3-5 cm into water, sheltering grafts with a moisture-proof and light-5 permeable coating, distinguishing H and, in order to increase the yield of grafted first-grade seedlings. in the side of the coating there are gaps left by the hole that allow air to flow with a temperature and humidity of 80-85%, and the flow of air should be set to 6973 60 6 at the top of the upper part to remain in the case of condensed water.
