The name of the inventor: Abaev AA
The name of the patent holder: North-Caucasian Research Institute of Mining and Fodder Agriculture of the Republic of North Ossetia Alania
Address for correspondence: 363110, Republic of North Ossetia-Alania, with. Mikhailovskoye, st. Williams, 1, SKNIIGPSH
The effective date of the patent: 2003.10.08

The invention relates to agriculture, in particular to plant growing, and can be used in the cultivation of juice. The method includes spraying plants three times during the growing season with a mixture of liquid fertilizers. Two or three treatments are carried out with a solution of Irlit 1 and Irlit 7 at a dose of 15 kg / ha each or Irlit 7-20 kg / ha, liquid complex fertilizers 10 kg / ha, potassium sulfate 11 kg / ha, urea 27 kg / ha 200 l water.

DESCRIPTION OF THE INVENTION

The invention relates to the field of agriculture, in particular to crop production.

A method for foliar fertilization of soya with a fertilizer solution is known - N ₂₀ , P ₂ , K ₆ , ₉ , S _{2, 7} . Edited by Yu.P. Myakushko and V.F. Baranov, Moscow: Kolos, 1984, p.178. However, this method is ineffective.

There is a threefold non-root addition of soya with a mixture of liquid complex fertilizers / HCV-10-34-0 / - 21 kg / ha, potassium sulfate - 22 kg / ha, urea - 55 kg / ha / Legumes and vegetable protein problems. P.Vavilov, G.S.Posypanov. Moscow, Rosselkhozizdat - 1983, pp. 79-80 /. The disadvantage of the method is the high cost of fertilizers.

The purpose of the invention is to reduce costs, expand the range of products for foliar supplementation of soy.

This goal is achieved through the use of local agro-irlite (Irlit 1 and Irilit 7), which have a rich composition of macro- and microelements.

The method is carried out as follows.

Non-root dressing of soybean plants is carried out three times with an aqueous solution of irilites or fertilizers with iriltites. The first spraying is carried out in the flowering phase - the beginning of the formation of beans and the two subsequent - in 10-12 days each. Spraying is carried out under high pressure in cloudy weather or in the evening.

Example 1. 15 kg of Irlite 1 and Irlite 7 were thoroughly dissolved in water until a liquid slurry was formed, poured into a spray tank and filled with 200 liters of water. The first treatment was carried out in the flowering phase - the beginning of the formation of beans. After 10 days, sprayed a second time, after another 12 days - the third.

Example 2. The first spraying was carried out with an aqueous solution of HCS - 21 kg / ha, potassium sulfate - 22 kg / ha and urea - 55 kg / ha. The second and third treatments were carried out with an aqueous solution of Irlite 1 and Irlite 7 at 15 kg / ha. Spraying was carried out at the same time as in the first example.

Example 3. All three sprayings were carried out with an aqueous solution of HCS - 11 kg / ha, potassium sulfate - 11 kg / ha, urea - 27 kg / ha and Irlite 7 - 20 kg / ha. Fertilizers were diluted in 200 liters of water. The timing of the spraying is the same as in the previous examples.

The results of field experiments with the isolated variants are given in the table. Experiments have shown that the effectiveness is higher when using Irlite 7 or Irlite 7 with Irlite 1 together with fertilizers. Irlite 1 / variant 9 / is less effective. The best results were obtained in variants 4 and 5 when using prototype fertilizers together with Irlite 7 at a dose of 30 kg / ha or Irlite 7 and Irlite 1 at 15 kg / ha. However, 8 and 10 variants with half doses of fertilizers and Irlith 7 at a dose of 30 kg / ha or Irlite 1 and Irlite 7 at 15 kg / ha are economically more expedient. And option 7 is effective with the first prototype treatment and the two following: the mixture of Irlite 1 and Irlite 7 at 15 kg / ha. Variants 5 and 6 of feeding only with a mixture of Irlite 1 and Irlite 7 in doses of 15-20 kg / ha are less effective than others, but also least costly.

The use of irilites alone or in combination with fertilizers for foliar supplementation of soybean makes it possible to increase the duration of general and active symbiosis, to increase the net productivity of photosynthesis and the yield of soybean grain, while reducing costs.

CLAIM

A method of foliar fertilizing of soybeans, including triple spraying of plants during vegetation with a mixture of liquid fertilizers, characterized in that two or three treatments are carried out with solutions of Irlite 1 and Irlite 7 at a dose of 15 kg / ha each or Irlit 7-20 kg / ha, liquid complex fertilizers 10 kg / ha, potassium sulfate 11 kg / ha, urea 27 kg / ha per 200 liters of water.
