Description

The invention relates to rural and forestry, in particular, to a method for developing slopes, and can be used in preparing the surface of slopes to create plantations on hills, hills, hills and industrial dumps.

The aim of the invention is to improve the growth conditions of the plantations due to the long-term supply of nutrients from fertilizers to the plant.

FIG. 1 shows a schematic terrace, a cross-section before fertilizer and fine earth are applied to the canvas; in fig. 2 - the same, after applying fertilizer and fine earth on the terrace and preparing for planting.

The drawings show a terrace 1, a notch 2, a bulk part 3 formed when cutting the terrace, a layer of fertilizers applied by a strip 4, a covering layer of fine earth 5 from the interterrenum space 6, seats 7 on the canvas and plants 8 planted in them.

The method of developing the slopes for plantations is carried out as follows.

Horizontally, from top to bottom, a terrace 1 is cut into a stepped helix on the surface of the slope, consisting of a recess 2 and a bulk part 3. Then, a portion of the sheet is fertilized with a strip of fine earth on the inner part adjacent to the excavation slope. S with vysheraspo ate

The interfacial interfacial space 6, and the handicraft of seats 7 are performed on the excavation part of the terrace cloth outside the layer of fertilizer covering the fine earth 5. Plants 8 are planted in a timely manner.

An example of the method.

On the mine dumps, the mines formed 0.3 m wide terraces with a 10 ° reverse bias of the web, and a part of the web adjacent to the excavation slope was applied with a strip of fertilizer (dry). The width of the strip is 5 cm. Fertilizers are covered with a layer of fine earth, the layer thickness is up to 5 cm.

The terracing was performed with an MTT-0.3 microterraser with a screw in the working device. Fertilization and backfilling were performed using a micro-tracer or manually.

Seats were prepared on the excavation part of the terrace cloth outside the layer of fine-grained fertilizer and were located in the middle of the terrace.

The terraces prepared according to the proposed method were distinguished by better forest conditions than the terraces created under similar conditions by a known method (table).

The use of fine earth to coat the layer of fertilizer applied to the terrace terrace protects the fertilizer from being blown away by the wind and washed away with sediments and is more economically efficient due to lower material costs. In addition, the application of a layer of fine earth to fertilizers ensures the rational use of fertilizers by plants and ultimately

provides improved growth conditions for plantations.

The terrace profile also ensures a more rational expenditure of the moisture that comes in with precipitation, making it flow directly to the plant roots.

The highest efficiency of the proposed method is noted on more moisture-supplied slopes of the northern exposure, where the proposed method allows the creation of plantations without irrigation.

The operations that constitute the proposed method can be fully mechanized.
