Abstract

THE METHOD OF CULTIVATION OF TUGAYNE ANEMOKHORNY TREES AND BUSHES, including sowing freshly harvested seeds to the surface of overmoistened soil and watering by infiltration, in order to increase the yield of seedlings by sifting the soil, sown by feeding them, in order to increase the yield of the seedlings and sowing, they are left to carry the seeds, and they have 4, and they are already covered with 4, and they are covered with seed to carry out seeds, as well as to carry out seed wedges, to carry out the sowing seeds the soil before sowing is covered with a layer of peat crumb ..

Description

The invention relates to the cultivation of planting material, mainly tugai anemochores-trees and shrubs, and can be used in hard necopaci of the title conditions of deserts and semi-deserts with severe water deficit. There is a known method of growing turang Topol, tugai willows and dressers, which includes vegetative propagation of plants due to the difficulty of obtaining planting material by seed 1. There is a known method of seed propagation of turang poplars, the essence of which is freshly harvested seeds. Turangovyh poplars are sown on a leveled and highly moistened surface of the group without embedding in the soil. The width of the group does not exceed 40 cm. They are arranged so that the shoots can be irrigated by infiltrative feeding. For both sides, watering grooves are cut on both sides. Shoots do not hay. Under the nurseries, it is necessary to choose sand-silt as well as takyr-like sierozems with buried meadow-humus horizons 2. However, this method of cultivation does not ensure the creation of conditions for successful germination of seeds, as well as obtaining high-quality planting material resistant to adverse weather conditions. Purpose of the invention. - increase output & yes of seedlings and increase their viability. The goal is achieved by sowing seeds in the phase of physiological maturity, and the surface of the soil before sowing is covered with a layer of peat chips. The proposed method is based on the fact that the natural seed resumption of turang poplars, tugai willows is carried out in nature at the time of the recession of flood waters and the formation of fresh shallows, on which mature seeds fall. The dates of ripening of seeds of mountain species coincide with the periods of decline of spring flood waters, and the ripening of seeds of lowland species — with the decline of spring-summer flood waters. The coincidence of the time of ripening of seeds to the dates of the formation of shoals has historically developed a feature of the turang poplars, tugain willows. One of the essentials) (factors contributing to the successful germination of seeds is the high humidity of the substrate and the surface layer of air. The surface of the shallows is well lit and warmed by the sun, which also favors the growth of seeds. It is sown and produced into special ones. checks with constant moistening that feeds through the draining layer. The drawing shows a sowing check according to the proposed method. The sowing check has concrete walls and a bottom 1. Its depth is 40-50 cm. A layer of drainage is placed on the bottom b, gravel 2. At the bottom level, a drain valve 3 is mounted, which serves to control the water level in the check. A wooden frame 4 is placed on the drainage layer. Substrate 5 is poured into the frame, which is covered with a layer of peat crumb 6. Between the sides of the check and the walls of the frame along the entire perimeter leave space for filling with water 7. Water in the seed check is fed through conduit 8 through valve 9, and is discharged into the drain pipe 10. The method is carried out as follows. Seeds collected in the phase of physiological maturity, are sown on over-moistened soil mixture in hydro-insulated, checks. The soil mixture consists of sand and peat in the proportion of 2: 1, which is covered with a layer of peat crumb, which serves to fix seeds on the surface. substrate and protect them from drying. The seeding rate of seeds is 50-100 pcs per 1 dm. - Sowing is done during windless hours, morning or evening. Figure 1 presents data on the output of turang poplar, Dzhungar willow, and various types of horse-dressers per unit of area, obtained using proposed and known methods. In tab. Table 2 presents the data on the number of seedlings of the turang poplars obtained by sowing seeds in the phase of physiological maturity and in the phase of sowing maturity, their quality and plant output per unit area after wintering. As can be seen from the table. 2, sowing of physiologically mature seeds as compared to sowing seeds in the phase of sowing maturity gives a higher yield of high quality planting material capable of successfully overwintering. In this case, the fallout of the winter period of seedlings of various ranks is 9.6%. the ranks of the East Persian - 5.5%. The fall of seedlings obtained from seeds of sowing maturity is much higher and amounts to 84.3% for a round of mixed leaves and 88.9% for East Persian turangas. The use of the proposed method of growing seedlings of turang poplars, tugai willows, and dressers in conditions of let and semi-deserts provides, in comparison with the existing methods, the possibility of staging standard seedlings annually.
