The invention relates to a method for increasing the yield of grain and a device for carrying out the method. For this purpose, it is known to peel the roots of the grain at a certain stage of growth and to change the relative height of the plants by so-called lowering. When the plants that have just been de-pitted, they lose their originally close root connection with the soil, growth is inhibited and the uncontrolled covering of soil that is then carried out after deep planting brings the risk of air exclusion for the weakened plant. This disadvantage also arises when, according to another known proposal, following the removal of the tips from the plants, the tuft of roots with the cut-off earth dam is pushed laterally offset deeper into a furrow that has been drawn at the same time. Other methods dispense with the Pinching, the seed set from the outset provided recesses in _<2o fixed slope and level these recesses by chopping or disking after completion of emergence of the crop a. Through this hooking or harrowing, the young plants can be torn out or damaged, while if this work step is not used, especially with hard topsoil, an additional covering with soil can hardly be expected. In particular, the large number of proposals has not given the farmer any clear teaching on technical action, so that an introduction into practice has not taken place. - Precision seeders with furrow coulter are also known.

The invention is based on the object of improving the known methods for increasing the yield of grain and of simplifying and making them cheaper to carry out with the devices necessary for this purpose. According to the invention, the seeds are placed in continuous soil hollows at a distance of 10 to 15 cm in a manner known per se and covered with earth, and in a second operation without changing the location of the plants after the stalk knots have formed, the plant roots are pruned, the stalk knots are covered with soil and pressed on the soil closure is brought about, whereby, as already explained, both the stripping of the roots without changing location and the filling of the soil hollows of deeply sown plants is known per se. In this way, the plants get a deepened location from the outset, which can be used to increase the yield of grain during the entire growing season and also through the additional interventions, such as de-sharpening and covering

with earth, is not impaired, so that an undisturbed Development of the plants is guaranteed.

The device for carrying out the process consists of a precision seeder with a furrow coulter, in which the furrow share is removable and on the two side cover shares, a pressure roller and sharpening knives with holding and centering device can be detachably attached. Because precision seeders anyway necessary and the additional facilities to be produced at low cost pressing and Are stamped parts, the effort for the device according to the invention is negligible.

In the drawing, the device designed according to the invention is shown.

A b b. I shows the precision air seeder in side view,

A b b. II is the top view of the machine according to Fig I.

The precision seeder, which can be attached to a chopping machine by means of the bracket 1, has a depth-adjustable and removable furrow share 2 on the front in the middle, a cover share 9 with share holder 11 and scraper 14 on each side, a pressure roller 15 at the rear in the middle and removable sharpening knives on each side 10. The parts further illustrated for the sake of understanding, namely the lower part of the seed container 3 and the lock 5 for one of the regulating rings 6 of the precision seeder adjustable for the passage of a certain type of seed, are not the subject of the invention.

Operation of the device

When tilling the field, the coulter 2 pulls a furrow, the depth of which is adjustable and in which the Seeds fall from the seed container 3 via the known seed drums and adjustment devices. They are then covered with soil by the furrow shares 9 and by the pressure roller 15 pressed on to the bottom.

After removing the furrow share 2 and mounting the sharpening knife 10 in a second Work step, namely temporally after the formation of the stalk knots, the roots of the stalk knots by means of the sharpening knife 10 sharpened and the Pfiänzchen at the same time with the help of the Zudeckschare 9 with earth covered. The Zudeckschare 9, which on both sides of the row of plants by a certain depth the earth are guided, are kept in length and breadth so that they are in connection with the Sharpeners 11 and the scrapers 14 only apply an appropriate amount of soil to the stalks Pushing plants. The earth must pass the openings 12, the size of each of which desired amount of soil for covering the seeds or stalk knots are placed while Larger clods of earth can also be diverted to the outside by the scrapers. This prevents that the cock knots are covered with too thick a layer of earth and suffer from the exclusion of air. The pressure roller 15 presses the the row of plants placed soil in turn in such a way that the soil connection of the stalk knots is established.

Claims (2)

Patent claims: 1. Process for increasing the yield of grain, characterized by the union following features: a) the seed is in a known manner at a distance of 10 to 15 cm in continuous Troughs in the ground and covered with earth, b) in a second step, the plants are not moved after formation the stalk knots peeled off the plant roots, the stalk knots covered with earth and by pressing the bottom closure, both the de-sharpening of the Roots without changing location as well as filling in the soil hollows deeply sown Plants is known per se. 2. Device for performing the method according to claim 1, characterized by the use a precision seeder with a removable furrow share (2), on the two side Cover shares (9), a pressure roller (15) and sharpening knife (10) with holding and centering device are releasably attachable.
