Abstract

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture. Method includes determining the volume of the soil, which is the product of the area occupied by the plant, sown according to the hexagonal pattern, and the depth of penetration of the roots. Effective radius of nutrition of pumpkin plants (b/2) is pre-determined. Volume is determined by the volume of a regular prism with a base in the form of a regular hexagon. Area occupied by the plant is determined by the area of a regular hexagon, obtained by connecting the midpoints of the edges of a hexagon formed by connecting the middle segments of the distances b to the nearest six plants and which is the base of a regular hexagonal prism. Depth of root penetration is determined by a segment drawn perpendicularly from any point of a regular hexagon down to a depth of 0.4 m and being the height of a hexagonal prism.

EFFECT: method allows to determine the soil nutrition zone of "Volzhskaya Seraya 92" ("Volga gray 92") pumpkin plants sown according to the hexagonal pattern.

Description

The invention relates to agriculture and can be used to determine the dose of fertilizer, the choice of the soil treatment system and other mechanical influences when cultivating pumpkins, depending on the specific soil and climatic conditions.

It is known that the volume of soil nutrition of a plantation is determined by the value of the root reachable soil horizon and represents the product of the planting area by the depth of root penetration (http://www.activestudy.info/obem-pochvennogo-prostranstva-zanimaemogo-kornevoj-sistemoj-dereva/).

For the prototype, a method was chosen for determining the size of the planting soil space (V _us ), which is determined by the root reach horizon and is calculated by the formula: V _us = S _us ⋅N _us , where: S _us is the area occupied by the planting; _We are the depth of root penetration, (lit .: Kalinin, M.I. Root studies. - M., 1991) (http://wvvw.derev-grad.ru/pochvovedenie/ploschad-pitaniya-rastenii.html).

A significant disadvantage of this method is the impossibility of linking the data to the selection and justification of the technology of cultivation of pumpkin plants "Volga gray 92".

The task to be solved by the claimed invention is directed to the development of a method for determining the size of soil nutrition to justify the Volga Gray 92 pumpkin cultivation technology.

EFFECT: determination of the size of soil nutrition of Volga Gray 92 pumpkin plants, planted according to the hexagonal pattern.

The indicated technical result is achieved by the method of determining the size of the soil nutrition of Volga Gray 92 pumpkin plants, including the determination of the volume being the product of the area occupied by the plant and the depth of root penetration, in which, as the plants, the Volzhskaya Gray 92 pumpkin is used, which is sown on hexagonal pattern, the volume is determined by the volume of the correct prism with the base in the form of a regular hexagon, the area occupied by the plant is determined by the area of the regular hexagon obtained by put If we connect the midpoints of the faces of a hexagon formed by connecting the midpoints of the distances to the nearest six plants, and which is the basis of a regular hexagonal prism, the depth of penetration of the roots is determined by a segment drawn perpendicularly from any point of the regular hexagon down to a depth of 0.4 meters and which is the height of the hexagonal prism.

The essential features affecting the achievement of the specified technical result are:

- the use of Volga Gray 92 pumpkin as plants, which is sown according to the hexagonal pattern:

- definition of volume in the form of the volume of a regular prism with a base in the form of a regular hexagon;

- determination of the area occupied by the plant, in the form of the area of a regular hexagon, obtained by connecting the midpoints of the faces of the hexagon, formed by connecting the middle segments of the distances to the nearest six plants, and which is the basis of a regular hexagonal prism;

- determination of the root penetration depth in the form of a segment drawn perpendicularly from any point of a regular hexagon down to a depth of 0.4 meters and which is the height of the hexagonal prism.

The definition of volume in the form of the volume of a regular hexagonal prism is due to the fact that the root system of the Volga Gray 92 pumpkin plants, with some tolerance, repeats this geometric figure. Changing the depth of root penetration is not advisable, since its increase leads to an excessive amount of fertilizer applied, and its decrease leads to a lack of nutrition. The invention is illustrated by drawings.

In FIG. 1 shows a plant layout and a method for constructing a regular hexagon.

In FIG. 2 shows a formed prism, a section of the soil.

The method for determining the zone of soil nutrition of pumpkin plants "Volga gray 92" is implemented as follows.

Preliminarily, the effective radius R (b / 2) of the nutrition of the Volzhskaya Seraya 92 pumpkin plants was determined, then the actual volume of plant nutrition for actual crops was determined taking into account the found effective nutrition radius and the depth of distribution of the root system. In the experiments performed at different distances between plants (within 0.5-3.0 m), the distance was determined at which the main pumpkin quality indicators according to GOST 7975-68 (appearance and size according to the largest transverse diameter) corresponded to the maximum values. Experiments were conducted with hexagonal placement of plants in the crop. This placement was formed as follows. The distance between each neighboring plant was b, the distance between each adjacent row was 0.85b (a coefficient of 0.85 is a constant value between rows in a hexagonal seeding system). In row 1 adjacent to row 1, each plant was also located at a distance b from the previous one, but here each plant was located opposite the middle of the gap between the plants in row 1, i.e. row 2 is shifted 0.5b in the direction of the rows. As a result, the plants in the sowing were placed uniformly as follows: one plant in the corners of the regular hexagon and in the center (hexagonal sowing pattern). Thus, each plant had six neighboring ones located at the vertices of a regular hexagon, in the center of which is this plant. They were located at the same distance b from the given plant and from each other.

The size of the soil nutrition of the plant was presented in the form of a prism, which repeats the root system of the plant.

Under the soil volume, the product of the area occupied by the plant sown according to the hexagonal pattern and the depth of penetration of the roots is taken. The size of the soil nutrition of the plant was presented in the form of a prism, which repeats the root system of the plant.

The size of soil nutrition was determined by the volume of the regular prism with the base in the form of a regular hexagon, the area occupied by the plant was determined by the area of the regular hexagon obtained by connecting the midpoints of the faces of the hexagon formed by connecting the middle segments of the distances to the nearest six plants, and being the base of the regular hexagonal prism, the penetration depth roots were determined by a segment drawn perpendicularly from any point of a regular hexagon down to a depth of 0.4 meters It is the height of hexagonal prism.

A depth of 0.4 meters was justified by the content of up to 95% of the root system of Volga Gray 92 pumpkin plants at a given depth, and the distance between plants b was chosen experimentally. Determining the size of soil nutrition made it possible to determine the necessary depth of cultivation, depth and quantity of fertilizers applied.

At the same time, between the sizes of the soil nutrition of plants there is an unused area necessary for preserving soil fertility for subsequent crops, taking into account the ability of the Volzhskaya Gray 92 pumpkin to sharply reduce the amount of nutrients in the soil.

Thus, the claimed method allows to determine the size of the soil nutrition of pumpkin plants "Volga gray 92", seeded according to the hexagonal pattern.
