HU197662B - Plant growth regulating composition - Google Patents

Description

FIELD OF THE INVENTION The present invention relates to a plant growth regulating composition which can be used in agriculture to supplement plant nutrients to increase the weight of plants and the number of reproductive organs.

It is known to have a growth regulator containing macro and micronutrients, the liquid phase of which is water and the ratio of nitrogen to phosphorus: potassium is 5: 1: 2 (Schering AG, Federal Prospectus: Wuxal-Suspension Typ 6, 1977; Hesal - ZICHP suspension instructions for use of fertilizers (1984)).

The disadvantages of the known formulations are that they cannot be used in higher concentrations because they contain synthetic and physiologically inactive minerals and organic additives and fillers, thus exceeding the limits of physiological excretion in higher concentrations. Another disadvantage is that they contain expensive chelating agents.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a composition for controlling the growth and development of plants which enables the growth of the weight and the number of the reproductive organs of the plant.

This object can be solved by a suspension composition containing macro and micronutrients, the liquid phase of which consists of whey in a concentration of 2 to 4 times concentrated and 8 to 12% by weight of lactic acid in an amount of 20-30% by weight.

An advantage of the composition of the invention is that it regulates the transport of assimilates in the plant, whereby the transport rate and accumulation of the assimilates is increased primarily in the reproductive organs of the plants, which increases the weight or yield of the plant. An additional benefit is that it increases the number of reproductive organs, which is a prerequisite for increasing productivity. The composition can be applied in higher concentrations by spraying with small amounts without causing burns or necrosis in the vegetative plant mass. A further advantage of the composition is that it has a strong buffering effect and thus allows the removal of various mineral salts without the addition of free mineral acid or alkali to control the pH. A further advantage is that the liquid phase of the composition is prepared from a waste product of the dairy industry.

The invention is illustrated in more detail by the following example (composition), Table 1.

Embodiment 1

The experiments are carried out using “Sadovo 1 wheat variety grown on leached sedimentary soil according to the agrotechnical proposal. The size of the experimental plot is 2 m ^{2 in} 6 replicates. The cultivation of the plant is carried out at the most appropriate stage of development: the stage of sprouting (long growth) and the stage of mass flowering. The spraying rate is 400-800 ml / ha.

The invention is further illustrated by the following tables;

Table 2 shows field yields.

Table 3 shows the absolute weight of wheat kernels obtained from the field experiment.

Table 4 shows the results of assaying the transport rate of the assimilate in the vegetative part of the wheat plant, where the plant is treated with an exogenous amino acid ( ^C14 -proline) in the vicinity of the reproductive organ.

Embodiment 2

For the tests, we use a "Kristi tomato variety, which was grown between June and September 1984. The experiments were performed with 15 plants per group in 3 replicates. The plants were sprayed four times with 0.3, 0.5, 0.5 and 0.5% by weight of the composition during flower formation.

The invention is illustrated in more detail by the following tables 5 and 6:

Table 5 shows the number of reproductive organs of treated tomato plants.

Table 6 shows the weight of the reproductive organs of the treated tomato plant.
