(54) METHOD OF CULTIVATION OF APRICOT SEEDLINGS

(57) The invention relates to agriculture, in particular, to fruit growing. purpose

invention - reducing the size of the tree and accelerating its entry into the fruiting period. A plum cutting of a length of 10–12 cm is grafted onto a cutting cultivated apricot, and then a plum with a grafted apricot is grafted onto a felt cherry, which serves as a stock of an apricot seedling. Intermediate plum insertion ensures compatibility of apricot grafts to the plum, and plums to cherry felt. The method allows to obtain planting material with increased precociation and smaller dimensions.

The invention relates to agriculture and can be used in nursery farms in obtaining apricot seedlings.

The purpose of the invention is to reduce the size of the tree and accelerate its entry into the fruiting period.

The method is carried out as follows.

They take a plum stalk 10–12 cm long and an apricot stalk with 3–4 buds. First, the apricot is grafted onto the plum, and then the cherry plum is felted. Landing and maintenance. During the summer, wild felted cherries and plum shoots are removed. By the end of the first summer the standard apricot seedling grows. If the cherries of felt from the floor are not dug out in the autumn, the grafting is carried out in late winter or very early spring in the same

in order, first, graft apricot on a plum, which can be done indoors, and then plum with a grafted apricot is grafted onto cherry felt in a nursery.

Grafting the apricot directly onto the cherry felt is impossible due to the incompatibility of the lead with the stock. The intermediate plum insert ensures compatibility of apricot grafts to the plum, and plums to the cherry felt. In contrast to the known method, where the intermediate plum insert serves as a shale former, i.e. the length is equal to the height of the trunk, the length of the intermediate insert in the proposed method is 10-12 cm, which provides for overcoming the incompatibility of the lead with the stock.

LR and meer. From the prepared cuttings of plum and apricot in the spring, 7 vaccinations of apricot varieties of Melitopol Early and Red-cheeked varieties were performed. Vaccinations were carried out in letters

tomnik without digging cherry felted. First, an apricot was grafted with 3-4 buds on a plum stem. The cuttings of plums were taken in a length of 6–18 cm. When grafting from 6 to 8 cm, incompatibility appeared. Experiments have shown that the use of more than 12 cm for cuttings of grafts is impractical because the dimensions of the seedlings increase. Thus, the optimum length of the stalk plum 10-12 cm

Then, a double inoculation was combined with the root, a felt cherry. By the fall, we received 5 standard apricot seedlings. As a control, the method of growing apricot seedlings by grafting a cultivar to an apricot of the same varieties and in the same amount was used.

In the spring of next year, the seedlings were planted on the experimental field. In the third year, we received 2–3 kg of fruits from each tree. In the controlled version, 2 to 4 kg of fruits were obtained from each apricot tree only in the fourth year after planting. The dimensions of the crown of trees by the proposed method in 1.5 - 2 times less than by a known method.

In February, we spent winter vaccination - first apricot on plum, and then plum from

grafted apricot grafted on cherry felt. In the nursery planted 40 seedlings. Survival rate of 85%.

The method allows to obtain planting material with increased speed, as well as reduce the size of an adult tree by 1.5–2 times, which for 1–2 years accelerates the production of commercial crops, halves the labor costs of harvesting it, because placed no higher than 2-2.5 m from the ground.

Invention Formula The method of growing apricot seedlings, which includes grafting to the rootstock as an intermediate plum insert, and to the intermediate insert, an apricot cultivar, characterized in that, in order to reduce the size of the tree and accelerate its entry into fruiting period, cherry and inoculum are used as the rootstock carried out in two steps, grafting first the cultivated variety of apricot to the plum, and then to the plum with grafted apricot to the felt cherry, while the size of the intermediate insert of the plum is 10-12 cm.
