Abstract

FIELD: agriculture.

SUBSTANCE: invention relates to the field of agriculture and can be used for weed control. The method consists in the fact that prior to the germination of weeds, a grid is laid on the soil surface between the rows. After the weeds germinate in it, the mesh is moved along the soil surface, while in the process of moving the weeds are cut off by means of the mesh material - wire.

EFFECT: invention provides a reduction in the time of weed removal using a simple design that implements the method.

Description

The invention relates to the field of agriculture and can be used for weed control.

The prototype is a method of weed control, which consists in the fact that the weeds in the rows and protective zones are preliminarily tilted towards the row and covered with soil with partial cutting of the stems in the aisles, while weeds are isolated from the stem of cultivated and weed plants of the roots in the rows and protective zones, sequentially tilt and move low-standing and overgrown weed stalks from a row of cultivated plants towards adjacent row-spacings while cutting their roots and stems in protective zones, loosening the topsoil cleared of them and shifting weeds into row-spacings, additionally cutting the inclined weed stalks along the boundaries of protective zones and spud cultivated plants in protective zones [US Pat. RF 2529311, IPC A01V 39/18, 2014].

The disadvantages of the prototype are:

- limited opportunities due to the fact that cultivated plants must be planted in a straight line;

- a relatively complex device that implements the method.

The objective of the invention is to expand the functional and operational characteristics, as well as to simplify the design that implements the method.

The problem is solved by the fact that in the weed control method, which includes the selection of weeds in rows and protective zones with partial or complete cutting of their stems, cutting is carried out by moving the mesh, which is preliminarily laid in rows and protective zones until the weeds germinate. The grid is moved upwards. The grid is moved along the soil to the side. After moving the mesh, weed stalks are left on it. Before moving the grid, the soil is irrigated.

These distinctive features allow you to achieve the following advantages compared to the prototype.

Carrying out cutting by moving the mesh, which is preliminarily placed in rows and protective zones before weeds germinate, makes it possible to simplify the design that implements the method, since practically one part is required for operation - the mesh.

Moving the mesh upwards contributes to the rapid removal of weeds by tearing their stems from the roots and even pulling out part of the weeds with roots, which expands the functionality and improves performance.

Moving the net over the soil to the side leads to the cutting of weed stalks even with a small movement, which reduces energy costs compared to raising the net and improves performance.

Leaving weed stalks on the net after it has been moved causes weeds to darken the row spacing and prevent weeds from re-growing quickly. In addition, the weed net prevents the rapid evaporation of moisture from the soil, which favorably affects the development of cultivated plants with spreading roots. This extension is functional and improves performance.

Irrigation of the soil before moving the net helps to soften the soil and remove most of the weed stalks with their roots, which improves performance.

The invention is illustrated by drawings.

Figure 1 shows a top view of the plants and the device for removing weeds. Figure 2 shows the section A-A of the device.

The device for weed removal contains a grid 1 placed on the surface of the soil (soil) 2, on which cultivated plants 3 and weeds 4 are located, having a root 5 and a stem 6 located in the cell 7 of the grid.

The method is implemented as follows.

Prior to the germination of weeds 4 on the surface of the soil 2, mesh 1 (or several meshes, depending on the size and configuration of the sheltered area) is laid in the aisles and protective zones. At the right time, the cultivated plants 3 are planted in their intended place (figure 1).

Over time, weeds begin to grow through cells 7 of the grid and grow in size. As soon as the part of the weed above the mesh increases so much that it is larger than the cell size, weeds can be destroyed (figure 2).

If the mesh is lifted, then the part of the weed located above the mesh will break away from its root 5 or pull it along, which in any case will lead to the death of the weed, and over all areas of the mesh. In the case of preliminary softening of the soil by irrigation, the number of weeds removed with the root may increase. After that, the mesh can be cleaned, for example shaken off, and put back in its original place for the subsequent destruction of re-germinating weeds.

The mesh can not be lifted, but only slightly moved to the side, while the material of the mesh, for example, wire, will act as a blade, through which the stems of 6 weeds will be cut. At the same time, small weed grass formed on the grid can not be removed. It, without interfering with cultivated plants and the penetration of water into the soil, will shade the aisles, preventing the rapid growth of re-sprouting weeds, and also retain moisture after watering. With repeated growth of weeds, the mesh is shifted again.

The implementation of the invention will make it possible to quickly and with low energy costs to destroy weeds using a simple design device - a grid.
