The invention relates to a method for promoting plant growth, in particular of Grains, oilseeds and other crops based on the exploitation of the properties of the Plants relies on forming additional rhizomes. These additional rhizomes get to the full development and represent a decisive strengthening and enlargement of the nutritional apparatus of the plants if soil is brought to those parts of the plant in good time and in the right amount from which new roots are possible.

This and the better soil ventilation achieved at the same time results in a stronger floor Utilization of soil nutrients achieved, which results in increased yields. Get the plants a better hold and are therefore less exposed to the risk of storage. Further additional secondary shoots can form, which still develop.

Since then, these processes, which are known per se, have only been used for the purpose of forming new shoots, tillering Experimental attachments come into use. It was done by sowing thinly with patters or in the deep-planting method of plants that were in disproportionately large distances from each other, to create as much space as possible for the heavily stocked plants. One such procedure is however, for agricultural field cultivation because of the too high workload and too little

Income totally unsuitable. That continues to be the case because it is too much of the exact time plant growth and suitable weather conditions, both of which must coincide is.

In contrast to this, the method according to the invention primarily relies on the New root formation. This makes it more independent of plant growth and weather and consequently a sufficient degree of certainty of success in large-scale cultivation is achieved.

The tillering of the grain is in the invention The procedure is regulated in such a way that it is initiated as early as possible so that the Can develop secondary shoots at the same time as the main shoot. Its just a waste of the Later tillering, which produces plant nutrients, is prevented.

Essentially, the process consists in sowing the seeds in furrows in a first pass sown and covered in the furrow with a thin layer of earth. When the plant is around has a height of 12 cm, the furrows that were excavated during sowing become

he embankments leveled in one operation. To Reaching a height of about 25 cm, the plants are in a third step, for. B. with With the help of a ridging plow, more heavily covered with earth. These operations can vary depending on the type of Plants to be treated and experienced deviations according to the soil. The last pile is so strong that new rhizomes can be formed through it; a disadvantageous one late tillering, however, is prevented.

All work necessary to achieve the desired effects can be carried out under complete Eliminate manual labor with machines. The yield obtained from the process is significantly increased compared to the cultivation methods known since then.

An example embodiment of the invention will be explained with reference to the schematic drawing.

Fig. Ι is a cross section through the furrows of a field after the first operation;

Fig. 2 is a cross-section through the leveled field after the second pass;

Fig. 3 is a cross-section through the furrows after the third operation.

i. Operation (Fig. 1), furrow drill sowing

In front of the drill coulter through which the seed 1 falls, a small ridging plow runs through one of them Furrow 2 is formed, in the middle of which the seed comes to lie. Runs behind the coulter a pressure roller, through which the earth at the bottom of the furrow 2 is flattened and in a thin layer is pressed a little over the seed 1. The well-known advantage of this furrow drill that the plant receives weather protection and a better microclimate during its first growth is for that present proceedings of minor importance. Rather, what matters is that that Seed 1 gets below field level 3 and thus more soil for later piling There is a disposal that could otherwise only be obtained by increasing the row spacing. This would j however, the yield per unit area will decrease because not the maximum amount of plants ever Area unit could be achieved. At the base between each of the two earth embankments 5 of two adjacent furrows 2 expediently always remains a narrow strip running in the plane 8 of z. B. 5 cm width free in order to have enough earth for the irrigation in the last step To be able to bring in plants.

In the case of particularly low-growing plants, the sowing can also be done in shallow areas instead of in a furrow.

80 2nd operation (Fig. 2), leveling

When the plant 4 has reached a height of about 12 cm, e.g. after 1 to 2 months, the earth dams 5 created during sowing as a result of the furrow excavation are leveled. The level field level 3 is created again from the furrow profile (dashed) lower part 7 of the young plants brought under the ground, whereby on it, in addition to the secondary shoots, Form new rhizomes. This can also be done by a light harrow stroke Weed control and soil loosening are done.

3rd operation (Fig. 3), irrigation

After the plant has reached a height of about 25 cm, which takes another 2 to 3 weeks of the If this is the case, a ridging plow is pulled through between the rows of plants, which brings the earth to both of them Raising sides, forming a deeper groove 6 in the middle. This makes the lower part 7 of the Plant again, more heavily covered with soil. As a result, the plant will be renewed Roots formed, one storey higher, so to speak, and the undesirable late secondary shoots suffocates, which, without reaching full maturity, would only consume nutrients unnecessarily.

The process ensures that the individual plant is no longer of one, but of three Root bundles are fed, thereby making better use of soil nutrients as well a higher yield is achieved. The latter is increased by the fact that the education is earlier Secondary shoots, which can still develop simultaneously with the main shoot, are favored will. The later, undesirable formation of secondary shoots, however, is prevented.

For plants that do not produce secondary shoots, e.g. B. with oil seeds, or when on the formation of secondary shoots If no value is set for other reasons, leveling after work step 2 is not necessary, i.e. H. on the profile of Fig. 1 follows the profile of Fig. 3, in that between the rows that are now in a furrow stand, a ridging plow is pulled through. This will probably focus on leveling, but not on No furrow drilling because otherwise

There is not enough piling soil in the row spacing would be available.

In soils which form only flat angle of repose of less than 45 ^0, a maximum number of rows per unit area, the finer crumbliness, grittiness of the soil exploited for the purpose of achieving. Here, instead of one, two to three rows of plants are sown in a wider drill furrow 2 at intervals that are about a fifth of the furrow spacing, while the spacing of the drill furrows is increased by about a fifth due to the shallower slope angle. In the later leveling and irrigating operation, which is carried out as described above, the soil covers every two or three rows of plants because it is crumbly or sandy enough to fall through between the plants. This band sowing can also be used for reasons other than the nature of the soil. It can also be done without the second step, ie leveling.

Claims (3)

PATENT CLAIMS: i. Process for promoting plant growth, in particular of grain and oilseeds, characterized in that a furrow (2) is formed in a first operation in which the seed (1) is placed in the middle during sowing, whereupon the earth on The bottom of the flattened furrow (2) is slightly pressed in a thin layer over the seed (1) is, as well as that at the base between each one of the two earth dams (5) of two adjacent ones Furrows (2) expediently a narrow strip (8) running in the plane remains free that in a second working cycle after the plant (4) has reached a height of about 12 cm, the resulting earth dams (5) be leveled again and that in a third cycle, after reaching a Plant height of about 25 cm, the plant (4) is covered with more soil, with between two rows of plants a deeper furrow (6) is created. 2. The method according to claim 1, characterized in that that in plants (4) that do not form side shoots, e.g. B. oilseeds, or if the formation of secondary shoots is dispensed with, and the first step is omitted the second step is followed by the third step. 3.
