Method for sowing acorns on matted forest soils involves creating a sowing furrow with formation of a protective zone, milling a sowing furrow, sowing seeds and compacting the soil. Creation of a sowing furrow is performed by cutting a matted soil formation at depth H=80–100 mm, its rotation and laying in the form of a continuous belt near the sowing furrow with a disk body, with simultaneous cutting of plant roots bordering the sowing furrow.EFFECT: invention allows to optimize process of acorns planting into soil, to increase its energy efficiency and to improve the acorns germinating ability.1 cl

Description

The invention relates to forestry, in particular, to methods of sowing large-fruited seeds of forest crops, for example, oak acorns.

The known method of sowing acorns ("Technologies, machines and equipment in forestry". LT Sviridov, VI Vershinin. Voronezh: VGLTA, 2002), including plowing the soil with a forest plow and sowing seeds using a forest seeder.

The disadvantages of this method of sowing acorns are high labor intensity, energy consumption and low quality of soil cultivation, which does not allow to form optimal conditions for the growth of oak acorns.

A known method of sowing acorns on sodden forest soils (Pat. RF No. 2236107; IPC А01С 7/00, А01С 5/00; publ. 09/20/2004), including the creation of a sowing furrow with the formation of a protective zone, milling the sowing furrow, sowing seeds and compaction soil. The creation of a sowing furrow includes cutting the soil with three planes to a width of 100 mm and a depth of 160-180 mm, trimming and sod removal to a depth of 60-80 mm with the formation of a protective zone. After that, the sowing furrow is milled to a depth of 80-100 mm, the seeds are sown at a distance of 20-30 mm from the bottom of the sowing furrow and the soil is compacted. The above operations are performed simultaneously with the use of circular knives, opener, wave disc and sowing device. Taken as a prototype.

The disadvantages of this method of sowing acorns are the increased energy intensity of the processes due to the large number of working organs, as well as the insufficient quality of the formation of the protective zone.

The problem to be solved by the invention is to reduce energy consumption and improve the quality of soil cultivation and subsequent sowing of acorns.

This is achieved by the fact that in the method of sowing acorns on soddy forest soils, including creating a sowing furrow with the formation of a protective zone, milling a sowing furrow, sowing seeds and compaction of the soil, according to the invention, creating a sowing furrow is performed by cutting the soddy soil layer to a depth of H = 80 -100 mm, its turnover and laying in the form of a continuous band next to the sowing furrow of the disc body, with simultaneous pruning of the roots of plants adjacent to the sowing furrow.

FIG. 1 shows a section of the sowing furrow after sod removal; in fig. 2 - the same, after milling the seed furrow; in fig. 3 - the same, after sowing and seeding.

The method of sowing acorns on soddy forest soils is as follows.

A sowing furrow is created by cutting a soddy soil layer to a depth of H = 80-100 mm, turning it around and laying it in the form of a continuous tape next to the sowing furrow with a disc body, with simultaneous pruning of plant roots adjacent to the sowing furrow, as a result of which the conditions for the growth of acorns are improved , and, due to the isolation of vegetation with a soil tape, a protective zone is formed for the epicate part of the sprout. Next, the sowing furrow is milled using a wave disk with a width of b = 30 mm and to a depth of h = 80-100 mm, the seeds are sown with a seeding device to a depth of h1 = 0.7h (h1 = 60-70 mm, 20-30 mm from the bottom of the sowing furrows), which improves the conditions for the survival of the root system, and performs soil compaction.

Due to the fact that to perform the above operations, in comparison with the prototype, only a disc body, a wave disc and a seeding device are used, the total energy consumption is reduced and the quality of sowing increases.

Thus, the proposed method of sowing acorns on soddy forest soils allows to optimize the process of sowing acorns in the soil, to increase its energy efficiency and to improve the germination of acorns.

Claims (1)

A method of sowing acorns on soddy forest soils, characterized in that it includes creating a sowing furrow with the formation of a protective zone, milling a sowing furrow, sowing seeds and compaction of the soil, characterized in that the creation of a sowing furrow is performed by cutting the soddy soil layer to a depth of H = 80 -100 mm, its turnover and laying in the form of a continuous band next to the sowing furrow of the disc body, with simultaneous pruning of the roots of plants adjacent to the sowing furrow.
