RU2605331C1 - Method of propagating clonal stocks of drupaceous crops at early stages of cutting - Google Patents

Abstract

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture, in particular, to gardening. Method involves preliminary disinfection using a container substrate from peat and coarse-grained sand at the ratio of 1:2. Propagated are clonal stocks of drupaceous crops by soft cuttings with semi-hardwood bottoms and they are treated with stimulants. Herewith the soft cuttings with semi-hardwood bottoms of 8-10 cm long are combined into bundles of 40 pcs. each. Prior to planting the semi-hardwood bottoms of the soft cuttings are levelled by cutting their roots with hand shears, processing them with a mixture of Fundazol and Ridomyl Gold by 0.2 % each for 15 minutes. Stimulator of rhizogenesis - acceleration of roots formation used is 50 % alcoholic solution of IBA (indolebutyric acid) in the concentration of 5g/l with the exposition 9 sec. Periodically the soft cuttings are exposed to an artificial fog for 2-30 minutes with the water drops value of up to 5µm depending on weather conditions.

EFFECT: method allows to shift the time of cutting in favour of early one that enables planting the clonal stocks of drupaceous crops at early stages.

Description

The invention relates to the field of agriculture, in particular to gardening. The method includes the propagation of clonal rootstocks of stone crops with grassy cuttings with a semi-lignified heel and treatment with stimulants.

A known method of propagation of cherry rootstocks with green cuttings, which consists in harvesting shoots with moderate growth, having a weakly or semi-lignified stem with a grassy top, and the leaves are fully formed. Green cuttings cut into a length of 5-12 cm (with 2-3 internodes). When cutting cuttings, the lower cut is made 0.51 cm below the kidney, the upper directly above the kidney. Before planting, the cuttings are treated with an aqueous solution of IMC (indolylbutyric acid) at a concentration of 25-50 mg / l with an exposure of 12-24 hours.

Rooted green cuttings in greenhouses with fogging plants, maintaining a temperature of 22-27 ° C and humidity 80-100%. Coarse sand, a mixture of peat and sand in a volume ratio of 1: 1 and 2: 1 are used as a substrate for rooting; peat with vermiculite and peat with perlite in accordance with 1: 1 [1].

The disadvantage of this method is the need to grow most of the rooted cuttings (60-70%) to standard sizes for another year.

There is also a method of propagation of clonal rootstocks of cherries by green cuttings, in which materials of inorganic nature are used as a substrate for rooting cuttings: various types of sand (river, sea) without organic impurities and soil, pebbles, fine gravel, crushed granite, zeolite [2] .

The harvesting of cuttings by this method is carried out in the phase of the beginning of intensive growth of shoots.

Cuttings with a length of 15-25 cm are treated with an aqueous solution of IMC at a concentration of 50 mg / l with an exposure of 12-24 hours. Rooted green cuttings in greenhouses, cold nurseries or other cultivation facilities with fogging plants. As a substrate, sand of coarse and medium-grained fraction is used, maintaining a temperature of 25-30 ° C, humidity 80-85% HB.

This method also does not provide a sufficient number of plants that can be used for planting in the first field of the nursery for budding or for winter vaccination in the year of rooting. Most plants have another year to grow.

There is also known a method of propagation of clonal rootstocks of cherries. Patent No. 2181938 for authors: Vekhov Yu.K., Gromova B.C. All-Russian Research Institute of Fruit Crop Breeding.

The invention is intended for use in agriculture. The method includes harvesting green cuttings of 15-25 cm in size from shoots with a semi-lignified stem with a grassy top, processing of IMC at a concentration of 50 mg / l with an exposure of 14 hours. Planting green cuttings is carried out in sand with a layer of 2.5-3 cm, which is poured on a mixture of turf land and humus with the addition of zeolite 9 kg / m ² . EFFECT: invention makes it possible to reduce the time for growing cherry rootstock.

The invention relates to gardening, and in particular to the propagation of stock and planting material of fruit crops.

The method is as follows. Grassy cuttings with a semi-lignified heel 8-10 cm long are combined in bundles of 40 pcs. and plant them in a pre-sanitized container substrate of peat and coarse sand in a ratio of 1: 2. Before planting on grassy cuttings, the semilignified heel is leveled, pruned at the base with a secateurs, treating them with a mixture of foundationazole and ridomil gold, 0.2% of each of them for 15 minutes.

As a stimulator of rhizogenesis (acceleration of the formation of accessory roots), a 50% alcohol solution of IMA (indulobutyric acid) is used at a concentration of 5 g / l with an exposure of 9 seconds. From time to time, grassy cuttings are exposed to artificial fog within 2-30 minutes and water droplets of up to 5 microns, depending on weather conditions.

The purpose of the invention: the shift of the cuttings in favor of the early, which allows the planting of cuttings of clonal rootstocks of stone fruit crops in the early stages (i.e. three weeks earlier than usual).

The goal is achieved through the use of grassy cuttings of clonal rootstocks of stone fruits with a semi-lignified heel.
