Method of cleaning fallow soil from weeds

FIELD: agriculture.

SUBSTANCE: method comprises ploughing, disking, subsurface treatment and combing. At that in July the fallow field is ploughed along the perimeter to the depth of 0.15 m, the width of the band is 10-15 m. The fallow soil of the entire field is cut to the depth of 0.06 m, and the plants are pressed to the ground. The aboveground mass is dried and burned, and the roots in the soil loosened to a depth of 0.15 m are removed to the surface of the soil and dried to lethal outcome.

EFFECT: method enables to improve the quality of cleaning fallow soil from hardly-exterminable weeds.


The invention relates to agriculture and can be used for intensive weed control in deposits by special treatment of the soil with the destruction of plant residues on its surface.

Known chemical-mechanical method of cleaning soil from weeds, which consists in spraying the herbicide continuous action (tornado, etc.). After the death of the plants is disking in two or three track with harrowing and subsequent sowing of cereals (Vityazev V. G., Makarov I. B. "General farming", Moscow University press, 1991, p. 105). Costs 2012 prices for these works constitute 1665 RUB./ha. the Disadvantages of this method are the high material costs, incomplete destruction of weeds (75-80%) and partial regrowth of weeds in subsequent years. Persists in soil for a living potential weed seeds.

The known method of intensive technological grinding machine (disk multirows DM-5,2 JSC "Belagromash" service to them. Ryazantseva, Belgorod) long-fallow. Shredded pieces of rhizomes and seeds of weeds especially in wet soil germinate quickly, requiring several re-treatments. The disadvantage is the repeated grinding, spraying the soil and conservation of the living potential weed seeds.

As a prototype the selected method of cleaning soil from weeds, including 2-3 Crat�e disking - (grinding rhizomes) after regrowth, subsequent deep plowing to a depth of 0.25 m and finally 2-3 cultivation with harrowing (Ermolayev, V., Tip I. P., DUDUK, A. A., etc., Agriculture: a textbook for students of agronomy specialty institutions providing higher agricultural Education - Mn: computer center of the Ministry of Finance, 2006. - 463 p.) the Disadvantages of this method - multistage, high cost of fuel and cleaning of rhizomes not more than 80%, remains alive potential crumbled weed seeds.

None of the known methods do not efficiently cleanses the soil from the roots and seeds of weeds. These features prompted us to use a new clean fallow soil from weeds.

The difficulty of clearing the soil from weeds is that in deposits, due to inter-specific struggle, a growing number of deeply rooted rhizomatous, creeping-rooted (e.g. couch grass) weeds. For many years in the absence of economic activity due to zavoianu in the upper soil layer is 0.03 m and the surface of the field focus millions of weed seeds that can germinate decades, reducing the yield of field crops.

Therefore, the method should destroy as living roots and primarily weed seeds. In the use of arable land seeds, leaving the rest condition, the active prorest�Ute, forming a large new lot of weeds, reducing the yield.

The purpose of the invention is to significantly reduce energy costs, improve the quality of clean fallow soils from hard to eradicate weeds.

This object is achieved in that fallow field, forest chopping, old perennial grasses for fire-prevention purposes ophelius plow on the perimeter (moldboard treatment to a depth of 0.15 m width 10-15 m). In July, the top layer (0-0,06 m) cut to desiccation living and dead parts of weeds. By July grows new crop, which increases the heat of the fire and increases the lethal effect of viable weed seeds. Stems and seeds are burned, and the roots are destroyed subsurface cultivator treatment to a depth of 0.15 m with simultaneous extraction of ground for natural drying to a lethal condition.

Fallow, overgrown with weeds, old grass, removing the weeds, effective fertility restored, after the application of the proposed method can be used productively - collecting 3-4 tons of grain per hectare. The area of such fields in Siberia makes millions of hectares.

Method is used in two stages the first is an old (over 10 years) fallow field, overgrown mainly rhizomatous, creeping-rooted and other hard to eradicate weeds, upahivaeshsya on �arimatsu, and its territory finely (0.06 m) cut by blade cultivator with simultaneous pressing of plants to the soil. This enhances the burning of seeds and powerful stems of weeds. Elevated weight gets dry and burnt. This is the only radical acceptance of the destruction of long-term water supply of seeds located in the surface layer of the soil.

In the second stage, to destroy the roots. For this root layer of soil (0-0,15 m), which focuses up to 98% of the rhizomes of couch grass and other weeds, pruned upgraded blade cultivator and also crushed a disk harrow to a depth of 0.06 m, breaking the lumps, penetrated by roots. With roots simultaneously extracted from soil using ring modular harrow (MBC - Leader, Siberian agro-industrial House). The roots are deprived of contact with the ground, dry up and die. Cleared of weeds fallow field and sown winter rye provided in 2012, a yield of 5.1 t/ha (OPH Siberian Agro-industrial House, Mashkovsky district, Novosibirsk region).

If the cost of fuel when using chemical-mechanical method amounted to $ 1665 $ /ha, according to the proposed method is 772 USD/ha.

The way to clean fallow soil from weeds, including plowing, disking, subsurface cultivator processing, combing, characterized in that in July-month fallow field on Prime�ru aphiwat to a depth of 0.15 m, band width 10-15 m, fallow soil of the entire field are cut to a depth of 0.06 m, and the plants are pressed to the soil, aboveground mass issuepedia and burned, the roots on the loosened soil to a depth of 0.15 m is recovered on the soil surface and dried to death.

SUBSTANCE: method comprises treatment of soil with simultaneous formation of soil ridges. After summer deep tillage before planting herbs the levelling and compacting is carried out in a single pass with smooth water-filled rollers. Planting is carried out with a mixture of stand of grass growing naturally on sod-podzol sandy loam soils with band stripes. Overseeding of tall-stem cultivated crop of corn is carried out with simultaneous formation of the ridges between the bands, and inter-row processing is not carried out. The tall-stem cultivated crop of corn, which has not reached its complete ripeness, is left for winter. The harvesting is carried out on the second year in spring before the vegetation of grass with grinding and removal of the stems with leaves from the field for dry feed with the subsequent feed additive. In addition, overseeding grass between the band stripes is carried out into mechanically damaged ridges, and top dressing of grass is carried out, which is harvested during the complete vegetation season. The distance between the stripes is taken as 20-25 m, and the row spacing of corn is 70 cm.

The method comprises cutting a groove along the site for determining the soil moisture capacity with the length of 0.5-0.7 m, width of 0.25-0.30 m to the depth of the estimated soil layer. Then, the groove is filled with water, water is supplied to the site from the grooves with infiltration for 7-14 cm, the water is discharged from the groove 30 minutes after pouring water. The groove is closed with boards or metal sheet, and the surrounding area within a radius of 1.0 m from the centre of the groove - with polyethylene film, 20 cm layer of straw and 20 cm layer of soil. The soil moisture capacity in the walls of the groove is determined on layers on the investigated depth in three, five, seven days in four-fold replications to establish a constant humidity, which will be considered its lowest moisture capacity (HB). Water to moisten the soil is fed from the groove, cut on the side of the experimental site, infiltration simultaneously in all layers.
