Abstract

FERTILIZER OF YLYA PLANTS OF LOCERNE on the basis of an aqueous solution of iron chelate compound, which, with, in order to increase the yield of seed and nectar-productivity of alfalfa plants, it contains an iron complex with ethylenediyeshindi with succinic acid in a concentration of 0.05-0.10% by mass (iron)

The invention relates to - agriculture, in particular to plant fertilizers by microelements. Fertilizer is known for various field and garden crops on the basis of xc of the complex compound of iron with ethylenediaminetetraacetic acid 1 However, such fertilizer is insufficiently Effective to combat the deficiency of metals, in particular iron. It is also known fertilizer for lyuda tserna on the basis of water Rastao. iron complex with dystilenetriaminepentaacetic acid (Re-DTPA-3) However, this fertilizer is not effective enough to increase the yield of seeds and nectar productivity of alfalfa plants, has high cost and toxicity; The aim of the invention is to increase the yield of seeds and nectar productivity of alfalfa plants. that, as a chelate compound, the fertilizer contains iron complex with ethylenediaminedisuccinic acid (re-EDADAUC) in a co-concentration of 0.05–0.10 wt.% (by). Fertilizer and Use alfalfa fertilizers during the beginning and end of plant budding. Consumption of the preparation is 5-7 kg / ha. If concentrations of less than 0.05% are used, the positive effect is reduced, application of concentrations higher than 0.1% can cause the plants to burn. they synthesize ethylenediamine diacarbonate acids (EDADAC) by condensation of ethylene diamine maleic acid in an alkaline medium, in a hard solution at elevated temperature. Fe-EDEDY is obtained by pouring out aqueous solutions of the iron salt (111) and EDADAC (20% excess) at pH 8.0-8.5, followed by evaporation of the solution to a paste. with a content of 15–20% water. In the form of paste fertilizer

Harvest Semyon alfalfa varieties Zaykevicha with foliar. iron supplementation

Table 1 is convenient for use because of its ease of dissolving in water. Fe-EDADAC, isolated in pure form, is a light brown-colored substance, very soluble in water and insoluble in organic solvents. Analysis of iron: Found,%: Fe 12,92. H | 5 Og N-KFe. 2 HgO B. Calculated,%: Fe 13,37. The complex consists of a biologist, the esky active components of the ligand, the content of aspartic acid residues, which causes the low toxicity of the drug (LD,. 450500 mg / kg). Example. Crops of alfalfa on the same agricultural background are divided into two sections. Spraying with Bordeaux mixture was carried out on one, and zineb on the second. Both plots are divided into cases, n & which, during the beginning and end of budding, foliar top dressing of Fe-DTPA and Fe-EDADYAK. The effectiveness of the preparations is analyzed on each experimental plot by two parameters: sugar productivity in the nectar of plant flowers, kg / ha, and seed yield of alfalfa, c / raj. Nectar is sampled by flushing it from the flowers during the period of maximum release. The amount of sugar in nectar is determined by the method of Shvedova A.С. and Lukw Nenko E. The record of the harvest of seeds of all the variants of the experiment was carried out by the method of continuous sharing of night harvesting and threshing. Thorough cleaning and weighing seeds. The test results are presented (l in Tables 1 and 2. All experiments are presented in two versions: the first always corresponds to the area treated with Bordeaux liquor, the second - with zineb. The control division is not fed with preparations.

As can be seen from the table. 1 use Fe-EDADYAK for feeding alfalfa into. a concentration of 0/1% increases the yield of alfalfa seeds by 57.3% (Bordeaux liquid) compared with the control, while Fe-DTPA only by 23.0%. And even the use of Te-EDC DYAK in a concentration of 0.5 % gives an increase in crop of sem and I

significantly higher, whose Fe-DTPA at a concentration of 0.2%, which is significant; but reduces the cost of the drug. Thus, the greatest effect: gives the use of Fe-edage in the background. jbordossian fluid. When using Re-EDADYAK against the background, a little fact is observed.
