Description

The invention relates to forestry, in particular, to methods for preparing soil for planting forest crops in clearings.

The purpose of the invention is to increase soil fertility and reduce the viability of competing tree species.

On cutting, shredding and pressing into the soil are logging residues; seed seeds of competing breeds are produced. Then they are plowed to a depth of 20-40 cm with a turn of the formation at an angle of 100-170 ° after experiencing the bulk of the stumps, and after rotting of the smelted wood residues, the soil is surface treated.

When implementing the method on poor soils with the aim of intensifying the process

Growing competing breeds at the same time as chopping and cutting forest residues into the soil is fertilized.

Chopping and cutting into the soil of logging residues is carried out by spurs or knife rollers. A similar operation is performed before tilling competing rocks.

Seeding of seeds of competing breeds is carried out preferably in the recesses in the soil from the spurs or knives of rollers and create young to a density of 50 - 250 thousand pieces / ha.

In order to create more favorable conditions for the rotting of plowed competing breeds, when they are plowed up, the bottom of the furrow is loosened.

In the implementation of the method on overmoistened soils before surface treatment, drainage grooves are created, and the soil to be removed is scattered across the inter-spacing of m,

In the case of resuming punching by young growths, they are treated with arboricides with a twice as much as usual.

Example 1. In order to carry out the proposed method on rich fertile soils and seed years, over the last cutting, rubbish was delivered to the soil surface with schlorovite rollers. Simultaneously with the extraction of rubbish, a partial marking of segments with a length of 20 - fbO cm occurred, after which the cutting was left for 7 - ID years on a scale. The number of the decomposition of the bulk of the lines and reaching the bottom is young. ke 6 m made a push down to the soil ... shdi - tJOB with simultaneous grinding them with spur rollers into segments 20–70 cm long, after which they were plowed by a planing plow to a depth of 40 cm with a turn of the layers through an angle of 100–170 °. Simultaneously with plowing, young layered rocks produced a rootless loosening of the bottom of the aisles with a deep-ripper plow to a depth of 25 cm, after which they left cutting in this state for 1-2 g to bend the young. Then, additional surface tillage was performed with disc plows in a designated crop row with a distance between them b m, after which the seedlings of valuable crops were planted,

Example 2. In the non-family year and on poor soils, fresh cuttings were carried out on the ground by means of rollers equipped with spurs. Simultaneously with crushing of rubbish to the soil of the p | K, its partial grinding into segments of 20–150 cm long occurred. Simultaneously with these operations, fertilizers were introduced and seeds of low-value hardwood were sown. Sowing of seeds was carried out in the soil depressions formed in the wake of the rollers spurs. After the occurrence of dense shoots of low-value hardwoods, the felling was left to overgrow until the period of decomposition of the main mass of stumps {7 - 10 years}. The cultivation of cuttings occurs with an extremely large density (50 - 250 thousand pieces / ra). When low-grade hardwoods reached a height of 6 m and, as the main stumps decomposed, they were pressed down to the ground and crushed by spur rollers into segments 20–70 cm long,

then they plowed the young using a planer plow to a depth of 40 cm with a turn of the seams at an angle of 100-170 °. Simultaneously with the plowing, the young were made, without a hole, loosening the bottom of the passages with a plow deep ripper 15 cm deep. The plowed cutting was left in this state for 2 g for rotting the young, after which

0 additional surface treatment of soil layers with strips with milling plows in the planned crop rows, while the distance between the axes of the strips of the strips corresponds to the spacing of the created crops.

The method allows to increase the soil fertility and reduce the viability of competing tree species in the process of preparing the soil for planting for the forest.
