Abstract

FIELD: agriculture.

SUBSTANCE: invention relates to the field of agriculture, in particular to horticulture. The method comprises preparing soil, planting seedlings, handling of plants, and harvesting. At that for growing seedlings the roots of hybrids are used, which preparing is carried out immediately after harvesting. Storage is carried out at temperature from 0°C to +4°C. In spring the shoots are separated from the stem part, which are formed from dormant buds on the roots of hybrids, the seedlings are grown from them, the seedlings are planted in the field.

EFFECT: method enables to provide the propagation of the most productive samples of rare introduced hybrid variety.

Description

The invention relates to agriculture and can be used in industrial, farming and amateur vegetable growing.

A known method of growing cabbage, including preparing the soil, planting seedlings, caring for plants and harvesting. At the same time, cabbage is grown to obtain the traditional commodity parts of heads of cabbage, stems, heads and leaves. It is grown with planting seedlings for 120-170 days.

A known method of growing cabbage, including preparing the soil, planting seedlings, caring for plants and harvesting, forms flowering shoots as a productive mass, for which seedlings are planted in two-year-old cabbage species in autumn, in annuals in autumn or early spring, and the first cut of shoots is carried out at the beginning of stem cleavage, leaving a stump 5-10 cm tall and a rosette of leaves, subsequent cuts of shoots are carried out as they grow, leaving leaves and 5-10 cm from the base of the shoots, until the end of shoot formation (pa ent of the Russian Federation №2086097, IPC A01G 1/00, publ. 10.08.1997).

To obtain high and stable crops, foreign and domestic vegetable growers widely use the seeds of hybrid varieties of cabbage of the first generation.

Seeds of hybrid cabbage varieties (white cabbage, cauliflower, etc.) are obtained in specialized scientific institutions by selecting and crossing parental pairs. Obtaining seeds of hybrid varieties in conventional vegetable farms is impossible.

A known method of growing cabbage from hybrid seeds of the first generation, including sowing seeds in a nursery, obtaining seedlings, planting it in a field of vegetable crop rotation, caring for plants, harvesting.

A known method of growing hybrid cabbage (CN 101657728, IPC A01H 1/02), including soil preparation, planting seedlings, caring for plants, harvesting.

The disadvantage of this method is the inability to propagate the most productive copies of rare introduced hybrid varieties.

An object of the invention is the cultivation of hybrid varieties of cabbage seedless method.

The problem is solved by preparing the soil, planting seedlings, caring for plants and harvesting, and for growing seedlings using hybrids roots, which are harvested immediately after harvesting, storage is carried out at a temperature of 0 ° C to + 4 ° C, in spring the processes formed from a sleeping bud are separated from the stem part, seedlings are grown from them, seedlings are planted in the field.

The implementation of the method of seedless propagation of the hybrid varieties of cabbage of the first generation was carried out on white cabbage varieties "Valentine", which is in great demand among vegetable growers.

In early November 2010, after the harvest of hybrid varieties "Valentina", harvested roots seed origin cabbage in their _^3/4 shortened stiff stems, roots washed free of soil and vertically stacked in a box with moist sawdust, then placed in the cold cellars. In early April, the roots were planted in open ground. Two weeks later, lateral shoots grew on the stem part of the roots, after they reached a length of 6-7 cm, they broke off, leaving one, and planted in a nursery according to the 6 × 6 scheme for rooting and seedlings. In the same period, seedlings were grown with seeds of the hybrid variety "Valentina". After rooting and reaching the seedlings with a length of 10-12 cm, it is planted in the field of vegetable crop rotation according to the scheme 50x60 cm.

Experience.

Experience conditions:

The soil is gray forest, loam;

pH 5.5; NPK security - medium,

precursor is potato;

hybrid seedlings "Valentine", obtained: a) by seed; b) vegetative (processes).

The experiment consisted of 3 repetitions of 15 pieces. in each. When planting seedlings, organic mineral fertilizers in the form of cubes were introduced into each well. Plant care consisted of irrigation, top dressing, pest control, and loosening of the soil.

Observations showed that plants obtained by seedless (vegetative) paths were significantly ahead of plants of seed origin in both growth and development. This was especially evident on the plant obtained from the process left on the uterine root.

The average weight of heads of cabbage was 4.2 kg.

Total harvest: 44 heads of seed of origin, weighing 109 kg (control);

45 heads of vegetation - 141 kg, weighing 141 kg (experience).

The excess in weight is 32 kg.

Claims (1)

A method of growing a hybrid variety of cabbage "Valentina", including soil preparation, planting seedlings, caring for plants and harvesting, characterized in that for growing seedlings using hybrids roots, which are harvested immediately after harvesting, storage is carried out at a temperature of 0 ° C up to + 4 ° C, in the spring, processes from the sleeping bud on the roots of hybrids are separated from the stem part, seedlings are grown from them, seedlings are planted in the field.
