Method of autumn soil strip tillage with variable-depth surface cultivator

FIELD: agriculture.

SUBSTANCE: method involves boardless strip soil loosening. Flat loosening of even strips is done at a depth of 0.28-0.3 m, and odd strips - at a depth of 0.1-0.12 m. On moderately weed infested and moderately packed soil, strips are made with width of 0.3-0.4 m. On heavily weed infested and packed soil, even strips are made with width of 0.4 m, and odd strips with width of 0.6 m.

EFFECT: such a technique allows for reducing power input on autumn soil preparation and increases snow water intake of the soil.

The invention relates to agriculture, in particular to energy saving methods autumn processing.

The known method of combating soil erosion "Method of combating soil erosion" (A.S. No. 880266,1979, AV 13/16), lies in its delavayi.

The disadvantage of this method is that when a slit ripping through 1 m is non-uniform moistening of the soil, and the edges of the cracks at the soil surface are formed pridelava rollers, preventing the penetration of water into the crack.

The closest to the technical essence of the proposed method is the conservation and efficient use of moisture (Shields A.G. Efficiency pure and employed a couple in rotation at the different ways primary tillage in the area of southern forest-steppe of Western Siberia // Discard. Oh. of Sciences, Omsk, 1984), consisting in ploskoreznaja processing 0.1-0.12 m and a deep band loosening 0.3-0.35 m 1-1,2 m

The disadvantage of this method is wide (1-1,2 m) finely processed (0,1-0,12 m) band, which comes from a deep (0.3 to 0.35 m) bands of snow water. However, it is usually not enough to complete wetting of the entire width of the finely processed strip.

The closest prototype is "Way lane subsurface-zero winter treatment on Chernozem soils in areas with insufficient hydration (patent RU No. 2284092, 2006, AV/00), when autumn is subsurface lane loosening the soil at 14-16 cm width 40 cm, which is alternated with untreated strip of the same width. The effect of blagoslovenija raw bandwidth is achieved by flow of moisture on the gable subsoil soles, as well as deeper ripping at the walls of a raw strip.

The disadvantage of this method is that it does not provide a continuous cutting of weeds, but only 50% of the area. The depth of the strip tilling in of 0.14-0.16 m - not enough for more intensive absorption of moisture and accumulation of biotic nitrogen.

The purpose of the invention is to optimize the parameters width and depth of the processed strips to reduce energy consumption for autumn processing and improve the assimilation of snow water.

This goal is achieved by the fact that ploskoreznaja loosening even bands perform at a depth of 0.28-0.3 m and odd lines to the depth of 0.1-0.12 m, and srednesemennyh and sredneprotsentnyh soils bands perform with a width of 0.3-0.4 m (figure 1), and very cluttered and crowded soils even stripes comprise a width of 0.4 m and an odd band - 0.6 m (figure 2). These indicators for medium - and heavy loamy black soils under the existing potential of rain turned out to be optimal.

By the time of sowing wheat humidity maloobrazovanna strip width ,4 m upper half fully aligned, that is, capillary moisture coming from loose deep bands in wall finely or untreated lane merges.

The specified parameters of the bands better retain, wet and smooth the water content, increase the content of biotic nitrogen and reduce by 20-30% energy intensity of tillage.

Way, depending on the environmental field (level of farming practices), is made in two versions. On srednesemennyh and sredneprotsentnyh soils width plascrete processed even and odd band is 0.3-0.4 m, and the depth of the even stripes of 0.28-0.3 m, and the odd 0,1-0,12 m (figure 1). On a heavily clogged and compacted soils even stripes of a width of 0.4 m plascrete rifletta to a depth of 0.28-0.3 m, and odd to a depth of 0.1-0.12 m and their width increases to 0.6 m (figure 2).

The method is as follows.

Ploskoreznaja the instrument is equipped with arched feet with a width of 0.4 m each. Installed to a predetermined depth, for example, even 0.28-0.3 m, and odd-0.1-0.12 m, spend way floating ploskoreznaja loosening. The processing unit on the field is moving celeno (figure 1).

On a heavily clogged and compacted soils even legs set at a depth of 0.28-0.3 m and a width of 0.4 m and odd-0.1-0.12 m and a width of 0.6 m In this format tool succorso performs floating strip tillage (Fig.).

In all cases Proskurina way floating treatment significantly reduces the amount of deformation of the topsoil.

The use of the claimed invention allows comparison with subsurface deep loosening racks, Cibima (control method) maximum accumulate, retain and evenly distribute soil moisture by the time of sowing of spring crops, to cut the weeds are on the whole treated area, to enhance microbiological processes and simultaneously reduce by 20-30% energy consumption achieved by a smaller amount of deformation of the arable layer. Due to the loose and compacted bands increases adaptability to unpredictable weather anomalies.


Field experiments in OPH "Elite" of the Novosibirsk region showed that a two-layer or single-layer lane loosening alternated with finely processed or zero band, compared with a continuous deep ploskoreznyh tillage (control variant) provided equal or higher pre-seed water content and grain yield of wheat. So, in the control (no-till continuous tilling to a depth of 28-30 cm) grain yield amounted to 22.2 kg/ha layer plascrete-lane - 23,3 kg/ha water stock in the m layer for sowing of wheat were, respectively, 67 and 86 mm

Method PLoS is aresnal lane floating autumn tillage, including subsurface lane loosening the soil, characterized in that ploskoreznaja loosening even bands perform at a depth of 0.28-0.3 m and odd lines to the depth of 0.1-0.12 m, and srednesemennyh and sredneprotsentnyh soils bands perform with a width of 0.3-0.4 m, and on a heavily clogged and compacted soils even stripes perform a width of 0.4 m and an odd band - 0,6 m

SUBSTANCE: method includes mechanical removal of oil products from the ground surface by collecting oil over a layer of contaminated soil with further oil refining. Mechanical admixtures containing fuel oil residuals are sent for washing. After removing oil products, the depth of soil contamination is determined, thereafter contaminated soil is frozen at the temperatures below freezing point to the depths lower than the level of contamination. Frozen soil which is lower the level of contamination is withdrawn together with clean soil and taken out for washing. Washing of oil contamination is carried out by using cleaning fluid which contains 0.3-3.0% of surfactant aqueous solution at the temperature not less than 40°C. Before washing, soil is fractioned into floating mass and deposited soil. Washing of floating mass is carried out by jet machining together with separating mass from contaminated cleaning aqueous solution. After washing, soil and/or separated mechanical admixtures are returned to the place of drawing, thereafter permanent grasses are sowed while adding mineral fertilizers, within two years woody plants and grasses are dressed with mineral fertilizers.
