(54) METHOD FOR APPLICATION OF FERTILIZERS AND DEVICE FOR ITS IMPLEMENTATION

one

The invention relates to agriculture and is intended to fertilize the soil when growing agricultural crops.

There is a known method of fertilizer application, including cutting gaps in the soil and distributing fertilizers therein, followed by termination of the latter.

A fertilizer applicator that implements this method includes a frame on which vertical stands with openers and feed lines 1 are attached.

There is also known a method of fertilizer application, which includes cutting gaps in the soil and distributing fertilizers therein, followed by termination of the latter.

A fertilizer applicator that implements the above method contains fastened blades on the frame, under which cylindrical casings are mounted with slots, inside of which are installed distributing working bodies 2.

The disadvantage of the known methods of fertilizing and devices for their implementation

is that the fertilizers are arranged horizontally. Such a distribution of fertilizers impairs their use. For example, when fertilizers are applied to a shallow depth, they are used by plants only in the initial period of their development, but with the departure of the roots of plants to a greater depth, fertilizers become inaccessible to the roots.

10 developed root system and sufficient moisture at this depth.

The aim of the invention is to improve the use of fertilizers.

This goal is achieved by the fact that, according to the method, the cutting of the gaps in the soil is made at an acute angle to the horizontal transverse plane with overlap of the other vertically.

At the same time cutting of cracks is made

20 at an angle of 30-45 °.

In a device for carrying out the method, cylindrical shrouds are mounted on the plowshares under sharp frail to horizontal horizontal 3974

The river plane with each other overlapping vertically, with each distributing body working made in the form of a cylindrical glass, on the surface of which a hatch is made, and a dimple is mounted on the bottom, and the cuts on the cylindrical shells are parallel to their forming,

At the same time cylindrical covers are fixed on a lumbar at an angle of 30 ... 45 °.

FIG. 1 shows a fertilizer device, front view; in fig. 2 - the same, rear view; in fig. 3 is a section A-L in FIG. one; in fig. 4 is a section BB in FIG. one; in fig. 5 is a section bb In figure 4; in fig. 6 is a section of YY in FIG. five; in fig. 7 — node I in FIG. one.

The device for carrying out the method of fertilizing consists of a frame 1 on which the plowshares 2 are fastened. Under the naslednigli there are cylindrical covers 3 having slots arranged parallel to them forming them. In cases 3, glasses 4 are installed, on the surface of which the screws of slot 5 are made, and impellers 6 are mounted on the bottoms 6. The lower parts of the impellers are not located in the area of the cutting plane of the plowshares 2. Tops of tubes 4 are connected to the glasses 4 from the top with the bunker 8. Frame 1 mounted on wheels 9. In the drawings, for understanding the essence of the method, the arable 10th 10 and the subarative 11th soil layer are shown. The cylindrical covers 3 are fixed on the shares of the plowshares 2 at an angle of 30-45 ° to the horizontal transverse plane with overlapping each other vertically.

In the implementation of the method of fertilizer in-cut into slits at an angle of 30-45 ° to the horizontal plane of the slit plane ... With such an arrangement in the soil, fertilizers are better used by plants. For example, this method, compared with the local method, allowed Astor to increase the yield of oats by 4%. This is due to the improvement of the conditions of fertilizer distribution over the height of the nutrient layer of the soil and the lack of screens for the development of the root system of plants, which allows an increase in the grain mass due to a more complete nutrition throughout the growing season.

The device for the introduction of the method works as follows.

When the machine moves across the field, the plowshares 2 are buried in the arable layer 10 of the soil and form inclined slots. Impellers 6,

following the bottom of the furrows, the cups 4 are rotated and, accordingly, the cups 4 are rotated into which fertilizers are fed from the bunker 8 through the tube lines 7. The latter, through the screw slot of the cups and the longitudinal slot of the covers, arrive at the surface of the furrows and close upon passage of the screws.

After the device passes in the topsoil 10, the fertilizer is distributed in the form of cutting strips overlapping each other vertically.

Such application of fertilizers eliminates their volatilization, washing away and weathering from the soil surface and ensures uniform nutrition of the plants during the whole vegetation period of development from germination to full maturity.

Claims (4)
