Abstract

FIELD: agriculture. ^ SUBSTANCE: invention relates to the field of agriculture and forestry. In the method seeds from blue forms of Colorado spruce in January are laid for stratification into pine chips at the temperature mode of +5+7C. In spring a plot for sowing is chosen, which is protected against direct sunlight. After tillage surface layer of 8-10 cm is planned and removed, and it is filled with soil taken under crown layers of spruce trees mixed with ground needle litter in the ratio of 3:1. Then it is rolled with a light roller. In spring sprouting seeds are evenly laid on surface of the prepared section and are coated with earth, which is also mixed with fround needle litter, with thickness of 0.5 cm with sowing norm of 16 pieces per 25 cm2. Watering is done by a watering can daily early in the morning and in the evening. Sprouts appear in two weeks with germinating ability within 85%, at the same time weeds are not removed, but are cut with scissors or pruning shears slightly higher than the level of seedlings. ^ EFFECT: method makes it possible to increase germinating ability of seeds and to produce high-quality seedlings. ^ 3 dwg, 1 tbl

Description

The invention relates to agriculture, namely to decorative gardening.

The scientific works of A.S. Sakharova (1961) highlighted the main methods of growing spruce spruce - from preparing seeds to growing in a medium.

According to the results of her experiments, spring crops with dry seeds give good results when out of 200 pcs. sown seeds grow annual seedlings of 125 and 128 pcs. (64%), while stratification in the sand - 53 pcs. (27%), in peat - 75 pcs. (38%), in the moss - 92 pcs. (46%).

In three variants of the experience in testing the germination medium, the following:

1. Sowing in a regular ridge into grooves 1 cm deep.

2. Sowing in a ridge in which grooves are made 5 cm deep, covered with 3 cm bottom layer of turf soil, and spruce sawdust with a 2 cm layer on top, seeds were sown in sawdust to a depth of 1 cm.

3. Sowing in ridges prepared according to the method of IP Kovtunenko.

According to the results of the experiment, sowing prickly spruce into ridges has an undeniable advantage over sowing in ridges, so out of 200 seeds 134 (67%) sprouted, while sowing in the usual ridge 55 pcs. (28%). (one).

The disadvantages of the method include the need to build labor-intensive cold greenhouses, the so-called ridges, in which seedlings appear only after 27-35 days, with low seed germination - within 65%.

The objective of the invention is to increase the germination of seeds and obtain high-quality seedlings.

The technical result is achieved due to the fact that the collected seeds from blue forms of spruce prickly in the month of January are mixed with coniferous sawdust in a ratio of 1: 3 (1 part of seeds and 3 parts of coniferous sawdust), stuffed into nylon bags and soaked in water for 2 hours. The excess water is squeezed and left for stratification in a room with a temperature regime of + 5 ... + 7 ° C until spring.

In spring, the selected area for sowing seeds should be protected from direct sunlight, it can be under the canopy of trees, in a shaded area from buildings and structures. The earth is loosened and planned, the surface layer of 8-10 cm is removed and filled with soil taken under the canopy of the mother trees of spruce, prickly, mixed with chopped needles of decay in a ratio of 3: 1 (3 parts of soil and one part of chopped needles of decay), and then rolled a skating rink, thereby providing a substrate in sufficient quantities with mycorrhizal fungi.

Seeds amicably peck by the third decade of April. Together with sawdust, they are evenly laid out over the surface of the plot and covered with soil mixed with crushed coniferous litter (3: 1) 0.5 cm thick with a seeding rate of 25 cm ² 16 pcs. seed. Watering is carried out with a watering can daily, early in the morning and in the evening. Seedlings appear after 2 weeks, with field germination within 85%, very tender, so weeds that are not removed, but cut with scissors or secateurs just above the level of seedlings (photo 1). By autumn, two-year-old seedlings reach an average size of 17 cm (photo 2). On a photo 3 - three-year-old seedlings.

Similar results for the proposed method are also obtained with the seeds of thuja western.
