Abstract

The invention relates to agriculture, and inno to the protection of soils from erosion. The purpose of the invention is to increase the efficiency of the method by improving the growth and development of tree species and creating a strength bond between the loose, covered soil and the bottom of the ravine. In the bottom of the ravine, wells are drilled to the depth of the groundwater. Live wells of lightly rooting tree species (hybrid poplars and willows) are planted in wells. The slopes of the ravine poured out with soil, cut from the peri-band, leaving the upper parts of the stakes on the day surface. Woody plants were planted on the upper and middle parts of the sloping slopes, as well as in the cut-off zone of the ground next spring. 2 Il. from €

Fig. Tenir: stksssits x agriculture, namely, to combat erosion no iHb, vi can be used for forestry and agroforestry,

The purpose of the invention is to increase the efficiency of the method by improving the growth conditions and the development of tree species and creating a strength bond between loose, covered soil and the bottom of the ravine.

Fig, 1 shows the placement of squash and plants; FIG. 2 shows a ravine in a section after dumping slopes with soil.

The proposed method involves planting; Shoots of woody plants 1 in boreholes 2, located in the bottom and lower parts of the gokos ravine 3, partially buried in sprinkled soil with a composition of surface parts 4,

For example, in the autumn, at the bottom of the ravine, with the D-YuM motor auger, drill holes 2 of 1 s depth, 5–2 m in diameter, with a diameter of 750 to them. Location of the well ijO-ljO Мо Then, into these wells ET, the hybridized poplars I-willows of 1 hybrid poplars And willows (os & brewing from the ends for pred1tr lkdo - r4- to heartbeat rot and za- Stakes length 1 jO-1 5 m extension B. the magnitude of the embedment and the well in the soil, o is the depth of the plant by the ekvazhichi.

After the cutting ((Kk), the dumping of the slopes of Obraga with a pick-and-shm from the enviromental zone by the bulldozer D-606 In a replay of the ravine slopes, the number of parts of the ravine of 150-155 m was found. upper

The groundwater effect of the planted tree species will increase as the p & TT of the IR systems.,

planting woody plants according to the standard technology

In the proposed method, planted poles have a higher viability than seedlings due to the greater biomass and better supply of moisture from deeper horizons, which guarantees a high survival rate and safety of created plantings and reduces the cost of supplementing forest species to 100% High aboveground (IjO-ljS m) parts of shoots and a significant depth of penetration of their underground parts allow them to successfully compete with weeds, suppress it, and thereby reduce the cost of agricultural practices

Factors 5 that provide accelerated growth of tree species are the best, microclimate, which is formed in negative relief forms, favorable water-physical properties and fertility of the filled soil and moisture in the dry period from deep horizons and genetic, capabilities of hybrids of easily growing and rapidly growing trees. best forest conditions.

The tests showed the high efficiency of the proposed method: survival rate of stakes 98%; the growth of shoots is on average 1.2 m, signs of erosion are insignificant (although the winter of 1986 was snowy, and in the spring of 1986 Go flowed close to the maximum in volume) 5 signs of slope erosion processes were not obscured

Formula inventions

The method of fixing ravines, including making recesses in the bottom part of the ravine and planting live stakes of lightly rooting tree species in them, which is different from that with the aim of improving the efficiency of the method by improving the growth and development of wood species and creating

Claims (1)

Claim A method of securing gullies, including making hollows in the bottom of the ravine and planting live stakes of easily rooted tree species in them, characterized in that, in order to increase the efficiency of the method by improving the growth and development of tree species and creating a strong bond between the loose soil and soil the ravine, depressions are made in the form of wells, the depth of which is determined by the level of groundwater, and after planting live stakes in them, the slopes of the ravine are filled with soil cut off from and strip, leaving on the surface the upper parts of the stakes of FIG.
