Abstract

Usage: in agriculture, in particular, in preparations for increasing the resistance of plants to adverse changes in moisture supply. SUMMARY OF THE INVENTION: An aqueous solution for spraying the leaf crown of plants contains 0.15-0.25% of complexonates of iminoduccinic acid with magnesium and zinc, taken in a ratio of 1: 1.4 of the table.

Description

The invention relates to agriculture and can be used in horticulture to increase the resistance of trees, in particular, bloni, to the lack and excess of moisture and their productivity in conditions of extreme variable moisture supply.

The aim of the invention is to increase the resistance of trees to adverse moisture supply and their productivity in conditions of extreme changes in soil moisture.

The goal is achieved in that the spraying of the leaf apparatus of plants is carried out with a 0.15-0.25% aqueous solution of a mixture of imonoduccinic acid complexonates with magnesium and zinc, taken in a ratio of 1: 1 parts by weight.

The advantage of the proposed composition lies in the fact that the use of separate complexonates of iminoduccinic acid (IDAC) with zinc or magnesium, as well as the use of 7pEDDAC (prototype),

causes a one-sided effect - increasing the resistance of plants to either a deficiency (2pEDYAK), or an excess (MADEDYAK) of moisture. The desired effect is achieved only with the combined use of complexon # gov2pEDDYAK and MdIDYAK in a concentration of 0.15-0.25% each. The advantage of the claimed composition is proved by the higher efficiency of the IDAK complexonates in comparison with the EDDAK for increasing the resistance of fruit plants to unfavorable moisture supply.

The complexonates of metals derived from succinic acid, as shown in additional sources of information (Chemistry in Agriculture, 1987. No. 1, pp. 48-49), are metabolized in plant cells to form several amino acids, including aspartic, which are a compound part of plant proteins. Magnesium, as the main atom of a chlorophyll molecule, plays a decisive role in photosynthesis; it is an integral part of other

important compounds, activates phosphorylation and protein synthesis enzymes. Zinc is involved in the synthesis of auxins, nucleic acid metabolism, and regulation of the activity of a number of enzymes providing heat and drought resistance.

The advantages of the claimed composition are illustrated by the following examples.

Example 1. For experimental verification of the proposed composition, we studied the effect of 0.15-0.25% IDNC complexonates with magnesium and zinc, as well as their combination in a ratio of 1: 1 wt.h. on the intensity of physiological processes, growth and development, bloom trees growing under conditions of temporary lack of moisture (option 70-30-70.% of the total moisture capacity); temporary excess moisture (option 70-100-70% of PV) and extreme changes in moisture supply (option 30-400-30% of PV). The experiments were carried out under controlled conditions of the Vegetation Complex of the Institute of Plant Physiology, Academy of Sciences of the Republic of Moldova. Humidity was established by watering the plants by weight to achieve a predetermined level. The duration of the effect of drought (soil moisture was maintained at 30% of PV) or waterlogging (100% of PV) was 10 days. A part of the plants of each variant was processed according to the prototype - gPEDDYAK, another - according to the inventive composition.

The results of many years of experience are presented in table. 1-3.

One of the parameters characterizing the resistance of fruit trees to unfavorable factors of moisture can be the ability of leaves to retain water under the influence of water stress. The obtained experimental data showed that under drought conditions, plants treated with zinc complex compounds had a significantly higher water retention capacity than plants treated with magnesium complexonates (Table 1). Moreover, iminodosuccinic acid complexonates have a more significant effect on the ability of tissues to retain water than ethylenediamine-M, M -disuccinic acid compounds. Under conditions of temporary waterlogging of the soil, a more significant effect on the water-holding capacity of leaves is exerted by treating trees with magnesium complexes in comparison with zinc complexes. The combined use of 7pIDYAK and MdIDYAK provides an increase in the water-holding capacity of the leaves both in plants growing under conditions of temporary drought and in plants excessively moistened. Similarly, it was found for plants growing against the background of an extreme change in moisture supply. The effectiveness of the claimed composition is high in comparison with the prototype reliable at the first and second levels of probability (table 1).

From the data of Table 2 it follows that the complex compounds derived from succinic acid, especially IDAC, with magnesium and zinc have the ability to increase the content of green pigments, thereby increasing the synthetic ability of the leaves. The results of the analysis of the pigment fund of the leaves of the Bloni plant in many years of experience have shown that 0.15: 0.25% IDNC complexes with Zn and MD in the ratio 1: 1 (parts by weight) have a more significant

0 influence on the content of chlorophyll quince. than EDDYK complexonates, increasing the resistance of trees both to the unfavorable (drought, waterlogging) background of moisture supply and to an extreme change in the level of humidity (Table 2).

Improving the physiological state and increasing the stability of the blonica plants to unfavorable moisture supply under the influence of a complex of IDYAC senates with Md and Zn favorably affected the manifestation of the potential productivity of trees growing under conditions of temporary lack and excess of moisture, as well as extreme variable soil moisture ( table 3). From table 3 it is seen that the treatment of plants according to the prototype (gPEDYAK) has a positive effect on the formation of fruit buds on plants under conditions of insufficient moisture and is ineffective with excess moisture in the soil; the use of the new composition provides an increase in the number of chamomiles per tree x both in case of lack and excess of moisture, and in conditions of extreme change in moisture supply. The differences in comparison with the prototype are significant in the second and third thresholds of probability. The effectiveness of the mixture of complexonates has been established to be more significant.

0 IDAC compared to EDDAC (td-2.61-6.1).

Thus, it was found that the combination of IDNC complexonates with Zn and MD at a concentration of 0.15–0.25% of each in a 1: 1 ratio has a positive significant effect on the resistance of bloni plants to unfavorable moisture supply.

Example 2. In the production garden of the farm-technical school to them. M.V. Frunze during the years 1986-1990 was propodono test

the influence of the complexions EDDYAK and IDK with Md and Zn on the physiological state and productivity of the blonie trees of the Goldenspur variety of 1978 planting. The experimental garden is located on the first terrace of the Dniester River. where in spring groundwater rises, reaching 0.5-0.3 m from the surface, and in the second half of summer it drops to 1.5-1.8 m, i.e. periodically the root system of trees experiences the effect of excess moisture and lack of oxygen, as well as temporary drought. In addition, the vegetation periods of the indicated years were characterized by insufficient rainfall, high temperature conditions of air and soil, and frequent dry winds, which created unfavorable conditions for the formation of fruit crop yields.

The effect of regulation of stability and productivity was studied both with the use of complex compounds MD and Zn separately, and their combination. Significant differences were found in the yield of trees treated with the proposed composition and control plants, as well as in comparison with the prototype (gPEDDYAK) and with plants treated with a mixture of gPEDDYAK and MdEDYAK (Table 4). As follows from table 4, the productivity of trees treated with a 0.25% solution of gPEDDYAK

(prototype) increased by 5-10% compared with the control; treated with a mixture of 0.25% gPEDDYAK and Mdedyak - at 20.8-. 26.9%; whereas the productivity of trees treated with the new composition was 130.0-138.3% in comparison with the control.

Thus, the use of 0.15-0.25% aqueous solutions of complex compounds of imino-succinic acid with magnesium and zinc in a ratio of 1: 1 for spraying trees increases the resistance of trees not only to lack or excess of moisture, but also to extreme change in moisture supply, which is important to maintain high productivity of fruit crops when cultivated in areas with unstable climatic conditions during the growing season.
