Description

"Accelerators for the growth of higher plants" subject of the Invention is the combination of well-known fertilizers and other types of influencing higher plants in the usual way applied means with chemical compounds certain constitution and / or configuration which is an unexpected and erratic Accelerated yield generation.

It is known that organic compounds of the most different constitution can be admixed to inorganic and organic fertilizers that are commonly used and that specific and desired effects can be achieved on cultivated plants by using such combinations. The main characteristics of their effect are primarily a yield, but additives have also become known by means of which a better quality of the fruit, parthenocarpy of the test, shortening of vegetative axes or induction of flower formation are supposed to be brought about. Additives frequently used for this purpose are growth hormones of the indolyl-3-eseigniura type, substituted aryloxyacetic acids, giberellins, choline derivatives or hormones of unknown constitution obtained from plants. But there are also combinations with other additives. Toaopherol and natural amino acids have been described partly in connection with synthetic growth hormones , with which an increase in yields is to be achieved. .. None of the previously known methods aims and achieves- .. an acceleration of the income generation in the sense of the inventive concept. .

It has been found that additions of 0.5 -. 4yo of organic compounds, which differ by slight constitutional but especially configurational .Knderungen of primary plant metabolic production bes amino acids, surprising to the usually higher for fertilization and different influencing plant agents used Accelerated earnings generation. It could be shown that the added compounds are absorbed smoothly by the roots and above-ground organs of the plants treated with them and that certain biochemical reactions evidently bring about a considerable acceleration of the mass and quality-building processes aimed at in practice.

Effective compounds of the claimed type are, for example, the D-imino acids, which differ from the ir-amino acids regularly occurring in plants only in the configuration at the atom, such as D - tryptophan, D-methionine, D-phenylalanine and D- Valine. But also other connections. which are characterized by slight structural changes compared to primary plant metabolites have proven to be effective, for example the DN-alkyl-amino acids, such as DN-methyl-valine and DN-methyl-leucine with the necessary for optimal nutrition of the plant population concerned. Quanity of MinsraldUagers. It is therefore advisable to add these substances to the agents intended for fertilization in the required quantities. This happens either in the production of solid fertilizers before certain final stages of production, whereby after the addition of the active ingredients no more temperatures above 80 0 occur and if wet phases are passed through, one is exceeded pH fourth of approx. 8, o, should be avoided because of the racemization that then sets in. Without special `oaa @. @@ instructions, the compounds can therefore be spread-ready, non-granulated fertilizers of all kinds, but also the fertilizers often used, especially in intensive crops - and other spray or silicone readings.

The accelerating effect of such a combination according to the invention is based on the example described below. Test series shows "Oldenburg ryegrass convincingly" Example 1 Acceleration of the formation of dry matter in Oldenburg ryegrass caused by a fertilizer containing D-tryptophan.

Two test areas (size: 1 vha each, soil: loess soil, in good culture) sown with Oldenburg ryegrass in spring.

Seed rate: 5 - 7 kg / vha.

The nutrients are applied to the test areas with the help of a sprinkler system administered in liquid form: test area I is according to plan with the normal Complete fertilizer nutrient solution fertilized, while the nutrient solution for the trial area II additionally D-tryptophan is added.

Two fertilizers are produced which contain the following proportions of the listed individual fertilizers: Fertilizer A (for experimental fertilizer B (for experimental area I) area II) 4o% potash salt: 28.57 % 4.y6 potash salt 27947% Superphosphate (16% P205): 42.86y6 superphosphate (16yP205) 41.2o% NH4N03: 28.57% NH4N03 27.47% D-tryptophan 3986% The test areas are fertilized twice 1.) 3 weeks after sowing 2.)

Fig. 1 shows the ratios for the total dry matter yields graphteeh shown again. This clearly shows that the dry matter yield on test area II the t; narrowness of the total yield on the trial area I has already reached 49% of the total vegetation time.

It is also pointed out that the quality of the harvested grass is not reduced by the increased yield, Example 2 Acceleration of dry matter formation in Oldenburg ryegrass, caused by a fertilizer containing DT "-ethionine , Soil: Zöß soil or loamy brown earth in good culture) sown with Oldenburg ryegrass in spring.

The nutrients are ready-to-spread on the test area Test area I brought to the plan is with fertilizer A, test area II with Fertilizer B fertilized.

Before the grass is sown, both test areas are fertilized with a basic fertilizer of the following composition: 40% potassium salt Zoo kg / vha superphosphate (16% P205) 150 kg / vha. ) fertilized with fertilizers A and B after the 1st cut.

In Fig. 2 the relationships for the total dry matter yields are shown again graphically.

This shows that the dry matter yield on the test area the amount of the total yield on trial area I after 49% of the total vegetation period has reached.

This process is completely different in terms of quantity and quality from the long-known increase in yield through the targeted application of fertilizers possibly with the addition of certain growth or other active ingredients. do such laas, which are considered to increase earnings, generally also to extend over time the vegetation phases, e.g. 3. intensive fertilization measures of the usual kind especially the fertilization with nitrogen to a temporal expansion under veäetativ -.
