METHOD TO GROW SCION-ROOTED GRAPE SEEDLINGS Russian patent published in 2011 - IPC A01G17/02 A01G1/00 

FIELD: agriculture.

SUBSTANCE: invention refers to agriculture, namely to vine growing. Method includes preparation of soil for planting of hefts, making hefts out of ripened vine, laying hefts for long-term storage, planting of hefts, vegetation watering, additional fertilising with macro- and microelements and protection of stock from agricultural pests and diseases. Besides, in the last decade of August - the first decade of September chisel tillage is carried out for depth of 0.5 - 0.6 m without mixing of genetic horizons. In the last decade of October - the first decade of November trenches are arranged with a pitch of 3 m and triangular profile, of "semi-groove - semi-fill" type, for 2/3 of depth together with treatment during chisel tillage in "north-south" direction. In early spring the trenches are straightened and covered with light-permeable film, hefts with length of 0.2 - 0.3 m with 2 - 3 eyes are implanted. As the soil temperature is stable in the bottom part of the trench, hefts are planted to the trench bottom. A flexible watering pipeline is laid with droppers of trickle irrigation system in the bottom part of trench along planted hefts. The trench is covered with light-permeable film, and the first watering is carried out as 300-400 m³/ha. At the temperature of air above +25°C the film is removed, one hose is formed. In autumn the ripened vine is filled up with soil from the semi-fill, leaving one bud of vine above the day surface. In the spring of the second year, a flexible watering pipeline is laid along the vine, one hose is formed, in autumn the vine is cut, and seedlings are dug out with a machine for planting in a plantation.

EFFECT: invention makes it possible to increase yield of standard hefts with limited quantity of hefts from promising brands and brand samples of grape.
