CS 268 800 B2

BACKGROUND OF THE INVENTION The present invention relates to a plant growth and development control composition which is used in agriculture to supply nutrients to plants to increase their weight and the number of their reproductive organs.

For controlling plant growth and development, a composition is known which contains nutrient macro and microelements, the liquid phase of which is water and nitrogen, phosphorus and potassium in the composition in a ratio of 5: 1: 2 (1, 2). »

The disadvantage of this formulation is that it cannot be used in larger concentrations as it would exceed its physiological safety limits, since it contains synthetic, physiologically inactive minerals, organic additives and fillers, and also because expensive chelating agents are used.

The object of the invention was to provide a means for controlling the growth and development of plants by means of which an increase in the weight and number of their reproductive organs is achieved.

This problem has been solved by a suspension formulation which contains nutrient macro and microelements and whose liquid phase is 2 to 4 times concentrated whey in an amount of 20 to 30% with a lactic acid content of 8 to 12%.

The advantages of the composition according to the invention are that the transport of assimilates in plants is controlled; in particular, the rate of transport and accumulation of assimilates in the reproductive organs of the plant increases, leading to an increase in their weight or harvest. Another advantage is that the number of reproductive organs also increases, which is a prerequisite for increasing productivity. The composition can also be used in larger concentrations when spraying smaller doses without causing burns and necrosis on the vegetative parts of the plants. Another advantage of the composition is that it exhibits a considerable buffering effect and it is possible to use various mineral salts without the need to add free inorganic acids or lyes to correct the pH of the environment. Another advantage is that it is possible to obtain the liquid phase by treating the waste products of the dairy industry.

The invention is further explained by means of the example (recipe) in Table 1.

The experiments used Sadovo I ^й wheat, which was grown on alluvial meadow land, excluded according to the agrotechnics recommended for the district. The size of the test plot was six times 2 m. · Plant treatment was carried out during the appropriate phases of their development: the shoot-forming phase (longitudinal growth) and the post-flowering phase. The amount of solution used for spraying was 400 to 800 ml / hectare.

The invention is explained in more detail by means of the attached tables:

CS 268 800 B2 assimilated from the vegetative part of the wheat plant, treated by the composition, near the reproductive organs using an exogenously labeled amino acid (C ¹ proline).

Example 2

The experiments were carried out using the type of Kristi tomatoes grown between June and September 1964. The experiments were repeated three times with 15 plants in each experiment. Plants were sprayed during flower formation at 0.3%, 0.5%, 0.5% and 0.5

The invention is further explained in Tables 5 and 6.

Table 5 shows data on the number of reproductive organs of tomato plants sprayed with the composition.
