concerning

Process to improve germinability, rising ge speed, emergence and pelletability of seeds.

The invention relates to a method for improving the ability to germinate, speed of emergence, end emergence and Pillability of seeds by pilling with minerals Coating compounds.

Such processes are already known. Thus, among other things, it has been proposed to carry out the pilling with a sub-bentonite clay with more than about 4 $ magnesium oxide content, but the main goal of piling has been to achieve sufficiently firm, uniformly sized and heavy seeds for the use of seed drills, whereby a positive influence on the germinability of the seed was observed as a side effect if the pelleting material contained sufficient amounts of germinating substances, including 15 to 25 volatile constituents, in particular water. Since the germination of the seed is already stimulated when aqueous suspensions of the covering material are applied, it has been proposed to prevent premature germination by adding readily soluble alkali or alkaline earth compounds. On the other hand, the coating or pelletizing compound can reduce the germination force by clogging the pores, which according to another suggestion by setting the redox potential duroh peroxide "" ■ ** 209 8 39/1 UV

hydrophobic additive or by adjusting the pH of the Pillierungsmasse or in accordance with other proposals by using a pelleting with porous or other substances comparable ■ - ■ '■ can be prevented.

Comparative studies between seeds treated with this type of procedure and untreated seeds Seeds from the same batch showed that especially those for the fast. Youth growth necessary high speed of emergence was not achieved in the treated areas compared to the untreated areas.

The often described improvement in the ability to germinate and emergence under field and laboratory conditions has not yet been significantly demonstrated in all cases will. The cause of undesirable phenomena of this type are, among other things, those in the context of seed improvement processes - Especially the pilling - used coating substances that z. B. a compromise between

a) the ability to be technically processed and

b) the possibility of germination and emergence in the field and Wanting to improve the laboratory.

It has been found that germination, Aufgangsgeschwindig- w resistance and Endaufgang of seeds can be significantly promoted and improved, when carrying out the pelleting with coating compositions containing the mineral content completely or partially burnt clays, silts, sands, optionally carbon, or mixtures thereof is replaced.

In the novel process, it is surprisingly not only to achieve in particular the rising speed of the required funding, although the wrapping materials used fired heating that is well over 200 ⁰ C

have been and therefore no longer contain water, but also to improve the technical pelleting process at the same time. With regard to the burned hair dryers, silts and According to the invention, it is possible and preferred to produce products to be used as they arise or fall off during the production of bricks, ceramics or porcelain products, i.e. For example, brick dust, ground pottery shards and false fires of porcelain or ground porcelain waste.

In particular, there is the shell material, which according to the Invention can be used from the following substances!

a) burnt clays in the broadest sense, loams, sands and / or their mixtures; Furthermore

b) burned substances also in mixtures with the under a) substances not listed, e.g. with carbon (coal dust, Graphite) and / or other substances that are also used for the production of other types of products Find.

These burnt substances can be used both from even in the most varied of relations sum - unfired Material used and / or included. The addition of heated material is independent of use and type of the raw material.

Fired montmorillonite or bentonite clays and / or brick flour are particularly preferred. Preferably the Enveloping compound made of at least 50% by weight of these substances, it can however, other proportions of these substances to customary pelletizing compounds or coating compounds can also be used.

The invention is illustrated in more detail by the following examples.

example 1

Instead of 12 kg of bentonite, 3 kg of bentonite and

9 kg of burnt - ° entonite

with 3 kg of a mixture of organic substances with additives of fungicides, insecticides and other germinating and growth-promoting substances in the manner of the known Pilling recipes processed.

All components are used as a combination of substances for pilling sugar beet seeds. The one for one Unit of seed required amount of pelletizing substance results from the variable requirement for size and weight of the pre-filled pill

Example 2

Instead of 12 kg of bentonite will be

9 kg of brick powder or mixtures of brick powder and burnt bentonite "» "Loess» »" ■ Kaolinite ¹¹ "'burnt other earths are used. Other additives are the same as given in Example 1.

Example 3

Instead of 6.9 kg of bentonite and

0.6 kg of diatomite are 3.5 kg of bentonite and
