Description

one

This invention relates to devices. used in the study of the microbiopotism of the soil, and can be used in agriculture and forestry.

A device is known for introducing tsepke 6 posture film into the soil, made in the form of a frame with through windows and pressure plates also with through windows. Lower-i n side of the frame is equipped with a pointed tsokoneche21ikom.jO

The disadvantages of this device are related to “with TC”: the complexity of introducing the device with a cellulosic film into dry and dense soil, insufficiently reliable contact between the walls of the well and the film and the deformation 18 of the latter when introducing and removing the device from the soil.

In order to eliminate such shortcomings, the proposed device is made in the form of a split ipsdra with a toothed bottom horse sharpened from the inside, having a lateral slot, with a tapered film straightener installed in its internal cavity.

FIG. 1 shows the proposed device; FIG. 2 shows a celled film fixed with capron capron and a capron cap film.

The device consists of a split cylinder 1 having a notched end 2 and a side slot 3. In the lower part of the internal cavity of the cylinder 1, the holder 5 is rigidly fixed by holder 4. Cellulose film -6 is attached to nylon film 8 by means of capron 7.

Before introducing the film into the soil with a soil drill with a diameter of 5-6 mm smaller than the diameter of the split cylinder, a well is drilled by 5-6 cm Dal: It is the investigated GLUOIN. Between each other, the nylon and cellulosic films of the Swara are dragged into a tube and inserted into the split cylinder half of its length, so that the joint space of the rolled films coincides with the holder 4, and when moving the butt edges of the film down relative to the destructible cylinder, it does not touch him

Then, by rotational and translational motion, the split cylinder op. flow into the well. In the process of movement, the toothed end of the cylinder cuts off a certain deformed brown soil layer, 6, which falls on the bottom of the well. Thus, the split cylinder, the passage down the well, creates a clean wall of the well. Reaching a given depth, under

holding the upper end of the cylinder-head with the right hand, 1PO, 1PO Dt giva1ot “it upwards, and the left end at the same time 1 Grips the nylon and cellulose films. In the process of moving the film between the inner wall of the split cylinder 1 and the extruder 5, the films around the IBst straighten out and fit well with the well rate. Having expelled the split cylinder from

wells last fall into the soil in the soil storm.

Formula of gain A device for introducing cellulosic foam into the soil when studying its microbiological activity, distinguishing it with the fact that, in order to facilitate and speed up the introduction of the cellulosic film into the soil, to improve the accuracy of the biing parameters of the latter, it was made as a split cylinder a sharpened toothed jagged bottom end, having a side slot, and with a conical film extractor installed in its internal cavity.
