It is established that the use of composite fertilizers with additions of microelements and biologically-active substances provides to increase crop capacity of fiber flax seeds by 0.2 - 3.5 hundredweight/hectare, yield of long-fibred flax is increased by 15-18% compared to standard composite fertilizers.

Description

The invention relates to the production of mineral fertilizers, in particular to the production and use of complex nitrogen-phosphorus-potassium fertilizers, which can be used in chemical enterprises producing complex fertilizers, and in agriculture for the cultivation of flax.

Flax is one of the crops that require both soil fertility and the availability of available nutrients in the soil, which is explained by the relatively shallow location of the roots in the arable layer, poor ability to assimilate hard-to-reach compounds from the soil, and a relatively short period of time during which the plants absorb the bulk of nutrients. Fertilizers are one of the means of increasing the yield and quality of flax.

It is known that under flax mineral fertilizers are applied taking into account the planned yield, the content of phosphorus and potassium available for plants in the arable horizon. For example, the ratios between phosphorus and potassium can be as follows: Ρ: Κ = 1: 1.22-2.0, between nitrogen, phosphorus and potassium Ν: Ρ: Κ = 1: 1.0-4.5: 2.0 -5.5 [1]. The disadvantages of these fertilizers include the following: the use of simple forms of one-sided mineral (nitrogen, phosphorus and potassium) fertilizers leads to their uneven distribution over the field area and, as a result, to uneven growth of flax plants and the deterioration of the quality and yield of long fiber, and the economic costs of applying unilateral fertilizers, compared with complex fertilizers, are much higher.

Complex granular fertilizers of the AGC enterprise are known! (Mariampol, Lithuania) grades Ν: Ρ: Κ = 8: 20: 30 + 2.5 8 and 8: 15: 30 + 3.0 8 with the ratios of batteries equal to Ν: Ρ: Κ = 1: 1.872 5: 3.75 [2]. The disadvantages of these fertilizers include the fact that the fertilizer contains no trace elements necessary for the growth and development of flax plants, as well as the ratios of phosphorus and potassium that are not entirely favorable for flax.

A number of patents are also known in which complex fertilizers for flax are considered.

- Patent AO 2001/030724 A1 (8. I. 8. O. 8OS1ETA ΙΝΏυ8ΤΚΙΑ 8Ε6ϋΕ8ΤΚΑΝΊΊ ОК6АХ1С1 8. К...), 05/03/2001) is devoted to the technology of complex fertilizers production both in the form of suspension and water-soluble granular fertilizers, where individual techniques of fertilizer technology. Only a qualitative composition is indicated in the patent, including macro elements (nitrogen, phosphorus, potassium), meso elements (calcium, magnesium, sulfur), as well as microelements (iron, manganese, zinc, copper, boron and molybdenum), however, their quantitative values are absent [3 ];

- in application 8ϋ 1727629 A1 of 04/23/1992 “Method for cultivating long flax” (Ukrainian Scientific Research Institute of Agriculture) provides for the application of a biohumus prepared from bedrock manure with the addition of shredded plant residues of crops, for example 15% chopped buckwheat or 10% potato tops . Due to this, for flax plants not only create the optimal ratio Ν: Ρ: Κ = 1: 2: 2, but also favorable agricultural conditions. A feature of this technical solution is that the fertilizer is organic, not mineral, and does not contain specific qualitative and quantitative characteristics of macro- and micronutrients that can calculate the dose of elements for the planned crop [4];

- in patent No. 2083078 C1 “Method for predicting the responsiveness level of flax flax to zinc fertilizer” (All-Russian Research Institute of Flax) dated July 10, 1997. This patent is based on the use of one microelement - zinc, in the form of a solution of zinc sulfate in a dose of 2 kg / ha D.V. into the soil under spring cultivation and cannot fully satisfy the needs of flax in nutrients [5].

The recommendations “The Use of New Forms of Mineral Fertilizers with Biologically Active Substances and Microelements for Flax Flax” (Gorki, 2000) provide an example of the use of encapsulated nitrogen-phosphorus-potassium fertilizer with a ratio of Ν: Ρ: Κ = 5: 16: 35 with additives of regulators plant growth (phenomelan or hydrohumate) and a content of Ζη 0.75% and B 0.6%, which we developed and are recommended for flax on soils with a very low content of boron and zinc [6].

Also known is a slow-acting complex nitrogen-phosphorus-potassium fertilizer with biologically active additives, which has high agrochemical effectiveness and is intended for grain and row crops. The content of the binder, which is mandatory, upon receipt of fertilizer is from 0.05 to 0.40%, the content of biologically active substances is from 0.05 to 0.15%. It contains no trace elements and the ratio of nitrogen, phosphorus and potassium in the fertilizer is not for flax [7].

The closest in technical essence and the achieved result to the proposed solution are complex nitrogen-phosphorus-potassium fertilizers [8] containing nitrogen, phosphorus, potassium and trace elements, for example, No. P: K = 4: 20: 20 + B, Md, 8 , C (the ratio Ν: Ρ: Κ = 1: 5: 5) and

Ν: Ρ: Κ = 6: 12: 24 + Μ§. 8, B, Cu, Her, Mn, Mo, Ζη, 8е (ratio Ν: Ρ: Κ = 1: 2: 4).

The disadvantages of these fertilizers are as follows: in fertilizer brand N: Ρ: Κ = 4: 20: 20 + B, Md, 8, Cu, the ratio of phosphorus and potassium is not quite favorable; in fertilizer N: Ρ: Κ = 6: 12: 24 + MD, 8, B, Si, Her, Mp, Mo, Ζη, 8е a very wide range of scarce and expensive trace elements in fertilizers that do not always respond positively to the yield and quality of flax . At the same time, the costs of producing such fertilizers are very high and do not always pay off by increasing the yield of flax products.

The objective of the present invention is to obtain a complex nitrogen-phosphorus-potassium

- 1 007603 fertilizers with the addition of trace elements and, if necessary, biologically active substances and / or binders, providing increased yield and quality of flax products.

The problem is solved by the fact that the proposed complex nitrogen-phosphorus-potassium fertilizers containing nitrogen, phosphorus, potassium and modifying additives, which are used as 8, B, Ζη, Her, and, if necessary, biologically active substances (plant growth regulators phenelane or hydrohumate or epin) and / or binders (sodium silicate or GRP). Fertilizers are intended for soils of different fertility levels (Ν: Ρ: Κ = 1: 1.9-3.7: 2.5-7.4).

The invention is illustrated by the implementation of specific examples.

Example 3

For 1 t of complex nitrogen-phosphorus-potassium fertilizer of the brand Ν: Ρ: Κ = 5: 16: 35, 1.7 kg of boron (0.17% by weight of the fertilizer) are introduced, 3.0 kg of zinc (Ζη 0.30% by weight of fertilizer), 2.0 kg of iron (0.2% by weight of fertilizer), 50 kg of sulfur (8 5% by weight of fertilizer), biologically active substances, for example, growth regulator Hydrohumate 5 kg (by dry residue 0.05 wt.%).

Example 4

For 1 t of complex nitrogen-phosphorus-potassium fertilizer of the brand Ν: Ρ: Κ = 5: 16: 35, 1.7 kg of boron (0.17% by weight of the fertilizer) are introduced, 3.0 kg of zinc (Ζη 0.30% by weight of fertilizer), 2.0 kg of iron (0.2% by weight of fertilizer), 50 kg of sulfur (8 5% by weight of fertilizer), biologically active substance - growth regulator Phenomelan - 6.4 kg (based on dry residue 0 , 05 wt.%) And a binder, for example, sodium liquid glass 2.0 kg (dry solids 0.12 wt.%).

Example 5

For 1 ton of complex nitrogen-phosphorus-potassium fertilizer, for example, grade Ν: Ρ: Κ = 6: 21: 32, 3.0 kg of boron are introduced (0.30% of the fertilizer mass), 4.0 kg of zinc (Ζη 0 , 40% by weight of fertilizer), 4.0 kg of iron (0.4% by weight of fertilizer), 25 kg of sulfur (8 -2.5% by weight of fertilizer), biologically active substance - growth regulator Epin - 0.0001 wt.% (dry solids) and a binder, for example a water-soluble polymer, 3.0 kg (dry solids 0.30 wt.%).

Other examples of the implementation of the inventive complex nitrogen-phosphorus-potassium fertilizers with modifying additives, for example, with ratios of nutrients not specified in the above examples, are implemented similarly.

Specific options proposed by the authors of the invention, including the well-known solution (prototype), are summarized in table. one.

The composition of complex nitrogen-phosphorus-potassium fertilizers given by us requires the presence of B, Ζη, and Eg. Moreover, depending on the level of soil fertility and its agrochemical indicators, sulfur, biologically active additives and binders may be absent in certain brands of fertilizers.

Agrochemical tests of the claimed fertilizers were carried out in field and production experiments. The yield of seeds, straws of flax and the yield of flax fiber in the experiment on sod-podzolic light loamy soil (Dzerzhinsky collective farm, Slutsk flax plant) in wet conditions in 2003 are given in Table. 2.

The data table. 2 show that when applying the claimed forms of complex fertilizer brand ΝΡΚ = 5: 16: 35 with modifying additives, the yield of flax seeds was approximately at the level of the base case and ranged from 9.5 to 10.8 kg / ha (a marked decrease in seed yield 0.91.1 c / ha is not significant, since the NDS 0.05 is 1.47 c / ha). The yield of flax straws ranged from 77.5 (basic version) to 78.2-81.8 c / ha (new forms of fertilizer). The addition of flax straw from the claimed forms of fertilizers ranged from 1.6 to 4.3 c / ha.

When using the claimed forms of complex fertilizers brand ΝΡΚ = 6: 21: 32 with mod

- 4 007603 with rutting additives, an increase in flax seeds from 0.9 to 3.5 kg / ha was obtained, and flax straws - from 3.3 to 12.3 kg / ha. The percentage of the total fiber content from the use of complex fertilizers with different ratios of nutrients varies slightly, but in general, according to the options of the experiment, it was from 26 to 34%.

The yield data of flax seeds and straws obtained in the experiment on the sod-podzolic friable sandy bedding, laid with 0.3 m loose sands, are presented in Table 3. On soddy-podzolic loose loamy soil in wet 2003, the yield of flax seeds and flax straw is significantly lower than on soddy-podzolic light loamy soils. However, the increase from the use of the claimed forms of complex fertilizers both for flax seeds and for flax straws is higher than on light loamy soils, tab. 3.

The data indicate that when using the claimed forms of complex fertilizers of the brand ΝΡΚ = 5: 16: 35 with microelements, or with microelements and biologically active substances, or with microelements, biologically active substances and binders, there is a tendency to increase the yield of long fiber 15.3- 18.0%, compared with basic complex fertilizer (15.2%). No significant significant differences were found in other qualitative indicators, for example, in the base ΝΡΚ - trust number - 1.25, length - 69 cm, strength - 20 kgf, suitability - 0.75; accordingly, from new forms of complex fertilizers - trust number - 1.0-1.5, length - 68-73 cm, strength -17-20 kgf, suitability - 0.73-0.74.

As for fertilizers of the brand ΝΡΚ = 6: 21: 32 with various modifying additives, depending on the claimed forms of fertilizers, the yield of long fiber ranged from 15.4 to 18.8% (base 17.7%), the number of trusts was from 1, 0 to 1.5 (base 1.5), respectively, length - 69-73 cm (74 cm), strength 17-21 kgf (19 kgf), suitability - 0.70-0.77 (0.73), color - 2.4-2.9 (2.5).

These data indicate the promise of the proposed complex nitrogen-phosphorus-potassium fertilizers for flax, modified with the necessary trace elements, or trace elements together with plant growth regulators, or trace elements together with the regulator

- 7 007603 plant growth tori and binders.

Introduction to the composition of complex fertilizers of these modifying additives in the claimed amounts allows to increase the yield of seeds and flax straws and to improve the quality and yield of long fiber in comparison with the basic version. At the same time, the cost of the proposed fertilizers is much lower than the prototype due to the exclusion of certain trace elements that do not affect the yield of flax.

The proposed complex nitrogen-phosphorus-potassium fertilizers with modifying additives meet the criteria of novelty, consisting in the combination and quantitative content of modifying additives in the fertilizer.

The proposed complex nitrogen-phosphorus-potassium fertilizers with modifying additives meet the criteria of an inventive step, they allow to obtain new fertilizers with a balanced ratio of nutrients for flax, with the addition of necessary trace elements and, if necessary, biologically active substances and / or binders that positively affect productivity and the quality of flax products.

The proposed complex nitrogen-phosphorus-potassium fertilizers with modifying additives meet the criterion of industrial applicability on the basis that during 2003 a pilot batch of one of the brands of the proposed complex fertilizers was manufactured at Gomel Chemical Plant OJSC.
