Description

one

This invention relates to the field of agriculture.

A known method for producing grapes soot is that the grafting is stratified before they are transplanted into the substrate, after stratification has been carried out and the appropriate graft mode is planted in the hydro-ionic substrate, where they are cultivated before being planted in the ground.

However, with a known method, the yield of seedlings is not high enough; moreover, the graft survival rate is not good.

The implementation of vaccination stratification, as a separate stage, isolated from the further process of growing seedlings, leads to the development of grafted seedlings of green grass in the production of plants.

During the stratification period, the root system develops on the basal shaft and on the graft, which then dies off when the grafts are planted in the substrate for further cultivation, and the plant is forced to re-root, spending its nutrients on the development of the new root system. This reduces the number of surviving irivivok, and also delays and impairs the intergrowth of the rootstock with graft.

The ingestion of imitative substances in the grafts from the hydroponic substrate begins

)

only after the development of the rootstock roots, i.e. after 5-7 weeks and after the start of vaccinations. This period is the sum of the period of stratification and quenching of the grafts before they are planted in the substrate (3-4 weeks), during which an intermediate root system is formed, which dies off at the landing, and the period of formation of the new root system (2-3 weeks). During this entire period, the plant spends on callus and corium formation only the reserves of its nutritional potential, without getting anything from the dichloride solution. This reduces the viability of nrivivok, degrades the quality of growth with iodine, reduces the survival rate of vaccinations and the yield of seedlings.

The aim of the invention is to improve the survival rate of vaccinations and increase the yield of seedlings.

This goal is achieved by planting inoculations into the substrate prior to stratification.

The method is carried out as follows.

The grafted cuttings are planted in a fine hydroponic substrate, for example, in sand, the humidity of which is regulated by feeding a nutrient sheath, where the inoculations undergo stratification, if quenching is needed, and grow to a permanent landing. Air is periodically purged through the substrate to improve stratification and growth conditions. All stages of development of vaccinations are combined into a single and continuous process.

After the graft is graded in the stock, for example, with an oblique cut with a tongue, the upper part of the grafts is 30-40 cm long and waxed and planted in a sandy substrate of a thickness of 30 cm, immersing the basal ends of the stock 8-10 cm in the sand.

A moisture content of 20–30% of the pore volume is established in the substrate. The temperature in the stratification of the room is kept within the range of 26-28 ° C, the air humidity is 90-95%. Once a day for 1 mpp through the layer of the substrate air is blown. By days 15–18, sprouts appear and callus forms at the site of adhesion. By the fourth week kopts, the moisture content of the substrate is increased to 40-60% of the pore volume, and the temperature of the substrate is increased to 20-23 ° C. This mode is maintained to the soil-growing seedlings. If necessary, quenching is performed by lowering the temperature n, therefore, the humidity of the substrate and the ambient air to the required mode. In order to remove the seedlings from the substrate, water is supplied to the post-pollen until the pores are fully saturated, after which the seedlings are removed from the root, there is no damage to the root system.

The resulting seedlings are good.

the accretion of the components of the nryvivok, their output

is 80%. This effect is explained

combining the stratification and cultivation stage in one process.

The root system, which is formed in the stock during the stratification process, is fully preserved and serves the plant during the remaining stages of its development.

The formation of the root system in a hydroponic substrate in the process of stratification promotes the flow of nutrients into the plant at the earliest stages of its vitality, which greatly enhances

it contributes to the fastest phase of the synthesis of plastic substances and, as a result, to the improvement of intergrowth and to the rootstock, as well as an increase in the survival rate of grafts and the release of seedlings.
