(57) Abstract:Usage: in agriculture. The invention relates to a derivative of pyridine, namely the coordination compound of manganese (2) gross f-crystals, Mn . The inventive compound is obtained by reaction chetyrehletnego manganese chloride and N-oxide of pyridine at 25 - 35oIn the environment of alcohol, in a molar ratio of 1 : 1, respectively. Yield 97%. Found,%: C-25,4, N-3,1, N-5,9, CL-29,4,5H7NO2Cl2MP. Calculated,%: C-25, 13; N-2,95; N-5,86; Cl-29,68. The compound obtained in contrast to standard and analogues greatly increases the productivity of cotton. table 1. The invention relates to a derivative of pyridine, namely the coordination compound of manganese gross formula
< / BR>having the properties of a plant growth regulator (productivity of cotton ).This property implies the possibility of its use in agriculture.The proposed connection is not described in literature.The closest analogue of the action and structure are:
1. Preparation a-1-the standard recommended by the Commission for use in improving the productivity of cotton.2. Succinic acid (similar to 1), is used in agriculture to increase the productivity of various crops.The claimed connection to their biological activity is much more similar. The proposed connection in comparison with the similar reduce the intensity of transpiration from plant leaves by 22.1% reduction in the percentage of movement of the bolls (buds, flowers) 16.6% and the yield of raw cotton increases by 6 kg/ha.3. Kapanen recommended as a plant growth regulator to increase the harvest of vegetables.The claimed compound has a number of advantages over similar Similar less available due to limitations in the feedstock, more expensive and more toxic. So, the value of LD60known and proposed connections respectively 340 and 1150 mg/kg of live weight. In its biological activity of the inventive compound is superior to analogue. Processing plants of cotton declare the connection has resulted in improved water, reduced water deficit at 1.8% felt the decrease in the intensity of transpiration 21.2% of the plant Treatment compound I regulated generative organs, contributed to the accumulation of bolls, in the variant with connection I was above 13.0% than similar. From the use of the claimed compounds, the yield of cotton was increased by 4.6 t/ha compared with the equivalent.The purpose of the invention the synthesis of new highly efficient and environmentally friendly plant growth regulator, which has high biological activity and low toxicity for humans and warm-blooded.This goal is achieved by the synthesis of coordination compounds of manganese, gross formula I:
< / BR>The proposed connection is stable during storage, water-soluble, non-hygroscopic and non-explosive.Brutto-formula of the claimed compound is confirmed by elemental analysis and IR spectra taken on spectrophotometer SEKORD-M-80.The presence of absorption bands in the spectra of the claimed connection: 1218 cm-1( NO ); 835 cm-1( NO ); 1025 cm-1( CN ); 3405 cm-1( OH ); 1625 cm-1( C=C ); 945 cm-1( CH2) argues in favor of this structure.Example 1. The method of obtaining complex.In dehgolan reactor with a capacity of 1 l, equipped with dropping funnel and reflux condenser, dissolve 197,8 (1 mol) couple the mole) of N-oxide of pyridine in 150 ml of ethanol (methanol). The reaction mass is heated to boiling, the solvent evaporated, the residue is washed 5 50 ml of ether. The output of the complex compounds of the formula I 231,7 g (97% ), crystallized from methanol, the compound decomposes when heated.Found, C 25,4 H-3,1; N-5,9; Cl-29,4; C5H7No2Cl2Mn.Calculated C-25,3; H-2,95; N-5,86; Cl-29,68.Example 2. The effect of the drug on the water regime and crop extra long staple cotton.Venue experience farm "Kyrgyzstan" Ilichevskogo area of the Tajik SSR. The experience of the field.The research object extra long staple cotton variety 9883-4
Processing method. The cotton plants were sprayed at flowering aqueous solutions of drugs in the morning. The flow rate of the working solution of 500 l/haThe area of 50 m2the fourfold repetition. Variant control plants were sprayed with water. Description of the experiment and the results are shown in the table.Plants growing under irrigation conditions, have low adaptive capacity. Weak changes of the water regime cause quite impressive metabolic and productive consequences.Processing plants offered by the substance causes a positive report and decreased moisture deficit with 24,0 to 15.6% ( table). This happened due to the limitation of the intensity of transpiration.The intensity of transpiration on the advanced options decreased from 1330 ( control) to 1781 mg/cm2h (table). Perhaps Ustica regulation of transpiration from treated plants offer substance was more rational and leaves are more resistant to stress.Plants treated with the proposed connection, spend less water, and in the leaves increases the number of tightly bound water and reduced mobility, increased water retention capacity of the tissues of the leaf, is the predominance of water flowing over its consumption.The proposed connection tendentious increases the resistance of cotton to stress in extreme conditions, thereby reducing the dropping of bolls by 12.4% in comparison with control (table).Improving water exchange in leaves, normalizing the physiological processes that determine the accumulation of bolls on the cotton Bush, the proposed connection contributed to the increase of raw cotton yield (table).The yield of raw cotton in the use of the claimed compounds increased by 5.3 t/ha compared to control.
synthesized a new compound, having the properties of a plant growth regulator with more stimulating activity than the standard and analogues;
the proposed connection provides:
a) improvement of the water regime of cotton, resulting in reduced abscission bolls;
b) increase of raw cotton yield of 5.3 t/ha in comparison with control, 5.2 t/ha in comparison with the standard;
the economic effect of the application of the proposed connection increases;
the intended scope of implementation may be 10000 ha. The coordination compound Mn(II)gross formula
< / BR>obtained by the interaction chetyrehletnego chloride m is its property to stimulate growth of cotton.
