SU1454289A1 - Method of sowing grass seeds when grassing eroded pastures - Google Patents

Abstract

The invention relates to a process of spreading grass seed on sloping lands using ballast materials. The purpose of the invention is to accelerate the process of setting eroded pastures. The invention proposes the use of chopped cutting of wild-growing steppe vegetation as a ballast material in the case of widespread planting of grass seeds in areas where widespread seedlings are unsuitable.

Description

one

The invention relates to agriculture, in particular to fodder production, in particular, to methods of sowing seeds of grasses when laying down sloping lands or eroded pastures.

The purpose of the invention is the acceleration of the process 5 of erosion of pastures.

When spreading seeds of herbs, ground shredded ripened wild steppe vegetation is used. The chopped cutting of wild-growing steppe growth (cutting length 3-4 cm) is a pile with low flowability. Such cutting had previously been applied only to cattle feed. Studying the cutting properties of wild-growing steppe vegetation shows that it can very effectively be used as ballast for seeds when they are sown widely. It uses its property that the particles of this cutting have a large adhesion coefficient with each other, as well as with such objects as seeds, soil. This property is especially pronounced due to the fact that many of them have strongly branched stems, the surface of the stems has a large roughness, notches, hooks or spec20

social spikes. When such vegetation is crushed, a heap is created inside which, under various mechanical effects, there is no redistribution of particles relative to each other. Seeds introduced into such cutting are located in a kind of rigid "spatial grid of plant particles - branched stems, rough leaves, fruits with notches. When scattering such a mass, a more intensive loosening effect is required. But in the process of cutting with seeds on the soil, there is no seed matching, and when it hits the soil surface, the particles of such cutting are well fixed on it again as a result of their contact properties - good adhesion. This property is not at all inherent to other types of vegetable cutting, for example straw of cereals. Therefore, as a ballast when sowing grass seed, such cuttings will not have an effect for the same reasons as the known materials.

Cutting wild steppe vegetation is characterized by other differences. Crushed cutting from ripened and growing vegetation has

Neemia with fertilizers, soil, water is less by a factor of 20-30 times. The use of a lighter material reduces the energy intensity of the processes of obtaining, feeding the dosing and scattering of a mixture of ballast and seeds, and reduces the size and intensity of the working bodies. It is also characterized by availability and cheapness. When scattering the cutting wild, (V vegetation together with grass seeds on the soil surface creates a wind-resistant mulch, a layer of leaves; the bleached pulp mass. Measurements show that with a seed spread rate of 1.5-1.8 tons / hectare soil cover reaches 75-80%. Such a mulch layer protects Pon from drying, which is favorably affected by seed germination and seedling development, as the recommended embedment depth of grass seed does not exceed 0.5-1.0 cm. Soil mulching at the same time continuously with the sowing is of particular importance in the southern parts of the country during the summer crops of forage grasses. The soil, fertilizer, water is not able to create on the surface

protective mulch layer. In addition, the mulch layer from the source-stem mass is clearly visible on the soil surface (in contrast to the known materials-ballasts). This eliminates blemishes when sowing grasses, makes it easier to dock the aisle of the unit, since the border of the sown and unpowered areas of the plot is clearly visible.

The proposed method improves the quality of soil and pasture silting as a result of the introduction of the cutting of many seeds of wild-growing flora.
