Abstract

Intensification of cultivation of agricultural plants and their controlled nourishing by a combination of a chemical treatment and a suitable cultivation technology. Agricultural plants are treated with a composition containing 2-chloro-ethane-phosphonic acid, microelements and additives, in a certain stage of their development, in the vegetative phase, nitrogen fertilizer is applied to the plants simultaneously with or prior to the chemical treatement and a fungicidal treatment is carried out, if desired the number of stocks is increased, nitrogen fertilizer is applied in more portions and other technological measures are employed to increase the efficiency of the compositions. The invention provides an excellent possibility for increasing the value of plants and the crop yield.

Description

The present invention relates to the intensification of the cultivation of arable crops, in particular winter barley, wheat, maize, sunflower, by a combination of chemical treatment and cultivation techniques.

In modern agriculture, there is an increased effort to intensify the production of arable crops, mainly through chemical treatments. Chemical treatment can generally be used to control the growth of plants, such as accelerating ripening, thinning of the fruit, and aiding the release of fruit. All of these treatments that influence plant growth can be accomplished with chemicals that are able to interfere with plant life processes. 2-Chloroethane phosphonic acid is one of the active substances used in agriculture to control the growth of plants. Its effect is mainly due to the release of ethylene. The induced physiological effect is described in detail in, for example, Hungarian Patent No. 160,618 and in Surányi: Growth Regulators in Horticulture (Agricultural Publisher, Budapest, 1978). book 16-18. pages.

Hungarian Patent No. 175,924 relates to the chemical treatment of a rye host plant by treating the rye plant with 2-chloroethane phosphonic acid prior to infestation and increasing the nitrogen content of the soil by fertilization within 5 days after infection. However, this method does not increase the yield of the rye crop, but increases the alkaloid production, which is due to the stem stabilizing effect.

A closer examination of the effect of 2-chloroethane phosphonic acid on plant growth showed that, unlike the literature, chemical treatment did not always produce the same effect, and in some cases growth depression and yield reduction were observed.

It has been recognized that 2-chloroethane phosphonic acid alone is not always capable of producing an additive effect in arable crop production unless it is combined with specific trace elements (nutrients), agricultural fertilizers, and other cultivation techniques. In this way, the content of the individual macronutrients and macronutrients in the plants is not fluctuating as a result of the treatment, but it can be kept unchanged and high yields of arable crops such as wheat, maize, sunflower and winter wheat can be intensified. are available.

The essence of the process according to the invention can therefore be summarized by treating the field plants with a composition comprising 2-chloroethanephosphonic acid, trace elements and excipients in the vegetative phase of their development, applying nitrogen fertilizer at the same time as or before the treatment and, if necessary, the use of nitrogen fertilizer sharing and deep fertilizer application.

The composition according to the invention containing 2-chloroethane phosphonic acid preferably contains from 85 to 90 g / l of 2-chloroethanoic phosphonic acid and contains the following components as trace elements in the form of a metal complex:

Zinc 9.8 g / liter

Skin 1.08 g / liter

Copper 6.5 g / liter

Magnesium 6.5 g / liter

Iron 7.6 g / liter

The amount of excipients that can be used is 16.3 g Triton CS-7 (36% octylphenoxypolyethoxyethanol + 24% sodium sulfosuccinate spray aid) and Nu-film 38.1 g / l (96% di-lp). -methane-containing film-forming spray additive)

The dose to be used during use is thus

next: Zinc 18-240 g / ha preferably 90-150 g / ha Skin 35-42 g / ha preferably 8-12 g / ha Copper 20-240 g / ha preferably 50-70 g / ha Magnesium 20-160 g / ha preferably 50-70 g / ha Iron 30-400 g / ha preferably 60-80 g / ha Flordimex 400-2000 g / ha, preferably 700-900 g / ha Triton CS-7 100-150 g / ha preferably 150 g / ha Nu-film 100-2000 g / ha, preferably 350 g / ha

The composition used as a micronutrient may be composed of a variety of commercially available products. The Fitohorm Standard K bioregulator kits contain cytokinin or benzyladenine and iron zinc. The boron solution used may also be a Fitohorm boron solution with an organic content of 7 g / liter in an organic chelated bond. The concentration of the magnesium, zinc and iron solutions, also in the form of a chelating agent, is 40 g / liter. These mono-active solutions are usually used as foliar fertilizers and have a pH between 5 and 7.7. Fertilizer as compared to the basic concentration

It is advisable to spray at a dilution of 6 to 10 times.

2-Chloroethane phosphonic acid can be used as a commercial formulation of Flordimex or Ethrel, usually containing 39% phosphonic acid and up to 1.6% H ₃ PO ₄ . The composition is applied in combination with sulfur at a rate of 1-6, preferably 3.5 kg / ha. Sulfur may be in the form of Sulfur 900 PV sulfur fungicide. Similarly, it is desirable to apply the composition in a tank mix with about 5 to 10 kg of urea (46.5% nitrogenous solid fertilizer) per hectare.

2-Chloroethane phosphonic acid can be used to aid in the maturation or drying of corn in amounts of 120-1200 g / ha, in combination with zinc trace and a complex fertilizer containing phosphorus pentoxide and potassium oxide. The drying effect of the latter composition can also be enhanced by the addition of rubidium at a dose of 80-100 g / ha. Zinc can be used in the form of Sequestren Zn (Ciba Geigy AG, Switzerland), this powder formulation contains 6.0% by weight of zinc in chelation form. The latter composition (II) is preferably applied at the following g / ha dose:

184,506

Flordimex 120-1-1200, preferably 800

Sequestren Zn 180-240, preferably 90

Tomasol K component, 20% by weight of phosphorus pentoxide and 5% by weight of potassium-3000 complex oxide fertilizer is preferably 3000

In addition to chemical treatment, it. some plants also require the use of the complex cultivation techniques described in the examples.

Example 1

Winter wheat cultivation

Phosphorus and potassium fertilizers should be applied as basic fertilizers in the autumn, in the amount required for the desired level. On fields with low Zn and Cue status of the soil, the micro-nutrients in question must be replaced by basic fertilization in the same amount due to ionic antagonism as planned yield. As a basic fertilizer, it is economically impossible to replace the higher nutrient requirements of Zn and Cu, and in the spring the foliar fertilization can be ensured by foliar fertilization.

20-30% of the nitrogen content required for the planned ternary level should also be applied as a basic fertilizer. It is not necessary in the case of butterfly progeny; in the case of maize, sunflower and sugar beet precursors, it is also advisable to add the amount of nitrogen needed to decompose the remaining organic matter in the autumn.

Adequate nutrient supply to the deeper layers of the soil, and deep fertilization are essential. It is also important that the desired yield levels for each soil type can be increased by 10-30%, preferably 20-25%, compared to the previously used.

The rest of the nitrogen fertilizer will be applied as head fertilizer in the spring. The first fertilization with ammonium nitrate or other nitrogen fertilizers, based on soil tests, is carried out a few days before the expected vegetation, depending on the stalk:

- 70-80 kg / ha in sparse herbage (2-3.5 million seedlings / ha) - 5-6 million overwintered stock and medium nitrogen supply 40-60 kg / ha - High stocking and good N supply 30-50 kg / ha N active ingredient.

The first treatment with the composition is to be carried out after the first application of 7-15, preferably 9.0 l / ha (or the equivalent) of the composition in the phenophase of the early stage of wheat shrubbing (according to Keller Baggiolini). The composition is applied in a tank mix in combination with 10.0 kg / ha urea and 4.0 kg or 1 / ha sulfuric fungicide (preferably Sulfur900 PW, manufactured by Budapest Chemical Works). This product can be sprayed both by land and air using 200-300 and 50-90 l / ha, respectively.

The second head-bedding after the start of the stem (according to Keller Baggiolini at the stage of development of the wheat) is carried out before the second chemical treatment due.

Depending on the soil quality of the soil, the crop and the desired yield level, 40-80 kg / ha of N is applied.

A second regimen treatment with the composition. immediately after the appearance of the second wheat nodule, at a dose of 4-8, preferably 5-6 l / ha, when the evapotranspiration is 1.5-2.0 cm long (according to Keller Baggiolini at wheat J developmental stage). This second chemical treatment becomes necessary when there is a risk of wheat falling over. The product should be applied by air using 50-90 IZha spray liquid.

It was expedient that the second chemical treatment of wheat had a water capacity of over 70%. It is therefore very advantageous to carry out this treatment immediately after a large amount of precipitation.

The third overhead fertilization is carried out after the appearance of the flag leaf (according to Keller Baggiolini in the K-L developmental stage of wheat), taking into account N-clarity, stock density and yield level with 30-50 kg / ha of N-active ingredient.

Soil protection work is carried out in a manner known per se, according to the commercial practice, according to the harmful situation and the weed conditions. When using a hormone herbicide, chemical weed control can be performed 7 days before or after regulatory treatment. If this happens afterwards, 70% of the approved dose of herbicide should be used.

Special attention should be given to the protection of pathogens, including powdery mildew, fusarium and rust diseases.

The necessary fungicide and insecticide spraying can be carried out simultaneously with the treatments of the invention. However, it is advisable to perform a simple mixing (physical) test before mixing.

Example 2

Growing of barley in autumn

The P and K fertilizers required for the nutrient supply are applied in the amount corresponding to the desired yield level as basic fertilizer. On fields where the Zn and Cu supply of soil is low, the micronutrients in question have to be fertilized to the intended yield due to ion antagonism! must be replaced at the same time. In the case of large Zn and Cu deficiencies, which cannot be economically replaced as basic fertilizers, the need of plants in spring can be ensured by leaf fertilization.

20-30% of the N-active ingredient required for the intended yield is also applied as a basic fertilizer. Butterflies can be omitted in the case of butterflies, but in the case of maize, sunflower and sugar beet, the amount of N needed to decompose the remaining organic matter is also important in the autumn.

The role of the nutrient supply corresponding to the deeper layers of the soil and the role of deep fertilization are essential. Thus, the yield levels can be increased by 10-30%, preferably by 20-25% compared to the usual. It is also available on soils with good nutrients and high yields with high yield varieties above the specified yields.

The remainder of the N will be applied as head fertilizer in the spring.

First head bedding with ammonium nitrate or soil3

Based on -3184,506 studies, other N-fertilizers are used a few days prior to expected vegetation, depending on the number of crops, as follows:

- 70-80 kg / ha in the sparse herd (2-3,5 million population / ha);

40-60 kg / ha with 5-6 million overwintered plants and medium N-spacing;

- 30 to 50 kg / ha of active substance in a stock with a high plant density and a high supply of N (eg peas progeny).

The first treatment with the composition is carried out in the phenophase of the early middle stage of barley sprouting (according to Keiier Baggiolini at the stage of development of barley E-F) after the first application of head fertilizer at 7-12, preferably 9-10 L / ha (or equivalent). The formulation is applied in a tank mix in combination with 10.0 kg / ha urea and 4.0 kg or liter / ha sulfuric fungicide (preferably Sulfur 900 FW from Budapest Chemical Works). The composition can be sprayed both by land and air using a spray rate of 200-300 and 50-90 l / ha, respectively.

The second overhead fertilization is performed after stalking (according to Kelier Baggiolini at barley development stage I) before chemical treatment.

It is advisable to apply 40-80 kg / ha of N-active substance, depending on the soil N coverage, the crop and the desired yield level.

The second treatment with the composition is carried out immediately after the appearance of the second barley nodule, when the unfolded cereal germ is 2.0-2.5 cm long (according to Kelier Baggiolini, at stage J of barley development). The composition is applied in a dose of 4 to 10, preferably 5 to 6 l / ha and is sprayed by aerial spraying at 50 to 90 l / ha.

It is important that the soil has a generating moisture when spraying the formulation. Thus, it is advantageous to carry out this treatment immediately after a larger amount of precipitation.

The third head fertilizer into the flag year! (according to Kelier Baggiolini at the developmental stage of wheat K-L), with N-active ingredient, 30-50 kg / ha, taking into account N supply, stocking density and yield level.

Plant protection work is carried out in a manner well known in the art in accordance with commercial practice, according to the harmful situation and the weed conditions.

When using a hormone herbicide, the chemical weed control can be performed 8 days before or after the treatment according to the invention. If this occurs, 70% of the approved dose of herbicide should be used.

Special attention should be given to protection against pathogens, including powdery mildew, and professional seed dressing against infectious agents at germination.

The fungicide and insecticide sprays to be used can be applied simultaneously with the regulatory treatments. However, it is advisable to check the compatibility by simple mixing (physical) test before mixing.

Example 3

Growing of maize

The stocking rate is set at 65,000-150,000 db / ha.

Depending on the number, variety or hybrid, oil yield, cultivation technology used, the possible yield level is up to 7-20.

Basic fertilization is carried out in the form of P and K in the fall, depending on the crop level. In fields where soil Zn and Cu supply is moderate or low due to the N-Cu and P-Zn ion antagonism, it is advisable to provide Zn and Cu supply corresponding to the desired yield level at the same time as the basic fertilization.

20-40% of the N-active ingredient required for the yield level should be applied as a basic fertilizer in the form of urea or ammonium nitrate. (Based on soil test data, other N-fertilizers may be used.) Higher doses should be used after abandoning pre-emergence crops (corn, sunflower). It is extremely important to perform deep fertilization.

In spring, before sowing, 40% of the N-fertilizer active ingredient to be dispensed is applied to the N-artificial bed determined on the basis of soil test data. The remaining 20-40% N is preferably added in the form of ammonium nitrate with a cultivator and row adapter at 50-70 cm of maize. The total amount of N-fertilizer to be dispensed in the spring before sowing can only be dispensed in one pass if a nitrogen stabilizer (eg N-Serve) is used.

The corn is treated with the composition at the time of 5-10 adult leaf stage development of the plant. 5-10 l / ha, preferably 6-7.5 l / ha. Dose size for corn treatment! depends on the maturity and the breeding time of the hybrid. Accordingly, early treatment (5-6 leaf stage) is performed at a higher dose, while late spraying (7-8 leaf stage) is performed at a lower dose. It is also lower in the case of hybrids with short growing times, while in the case of long hybrids! the higher dose is used.

The treatment is always carried out at a rate of 5-10 L / ha with the addition of 46% urea.

The treatment is carried out by land, using a spray rate of 150-400 l / ha.

Example 4

Sunflower cultivation

The stocking rate is set at 50,000-80,000 db / ha.

The desired yield level can range from 2.5 to 4.5 t, depending on the number of plants, the variety or hybrid and the fertility of the soil and the cultivation technology used.

The basic fertilization (P and K) is applied in the autumn in accordance with the desired yield level.

N is added as a basic spring fertilizer at a dose of 80-150 kg / ha, depending on the crop level, depending on the soil's N content. 80 kg for high supply or lower yields, 150 kg / ha for poor supply or good supply.

For bound airless soils, N is preferably used in the form of urea or possibly ammonium nitrate

Chemical treatment with the preparation of sunflower

8-16 leaf stage (50-60 cm height)

5 to 10, preferably 5.5 to 6.5 l / ha.

Both treatments were performed with the addition of 10 kg / ha of 46% urea.

Example 5

Soybean cultivation

The precursor of the area was winter wheat. The soil was plowed 22-26 cm deep in autumn after harvest. In the spring after leveling the area

N = 70 kg / ha Ρ ₂ Ο _ε = 100 kg / ha K ₂ O = 100 kg / ha sprayed.

After pre-emergence weed control, the seed treated with fungicide was sown at 180 kg / ha. Following a herbicide and fungicide treatment, the treatments of the invention were carried out at two time points in the soybean vegetative stage before budding and one month after emergence at budding. Doses of the preparation were as follows:

control

1 / ha 4 1 / ha 6 1 / ha 8 1 / ha

4 repetitions; plot size 2x10 m. The results obtained are all. is illustrated in Table.

From the data it can be concluded that the preparation is

At time of treatment I increased yield proportionally with dose. Even at the lowest dose (2 l / ha), the yield was 0.337 t / ha. The increase relative to the control at the 8 l / ha dose was 0.78 t / ha.

At the second treatment time, the plants responded similarly to the treatment of the invention.

When using the process of the invention, it is essential that certain cultivation conditions are met. These include, but are not limited to:

- nutrient replenishment (macro- and micro-nutrients) corresponding to the intended yield, in appropriate quantity, quality, variety and timing;

- performing deep fertilization due to the deep root system of the plants;

- 10-50% increase in the stock of maize and sunflower. control of shrubbery when sowing today and in cereals;

- changing row and plant spacing, since lower plants require less breeding space;

- to provide a machine background appropriate to the changed technology.

The increase in the yield of the cultivated plants and the improvement of the quality of the crops are the following factors:

- increased plant endurance (resistance to stalk breaking and tipping);

- improved drought tolerance through root surface and depth growth and stimulation of respiratory mechanisms;

- elimination of the adverse effects of excess nitrogen (feeding) (loosening of tissues, inclination, susceptibility to germination), thereby exploiting the yield-enhancing and quality-enhancing effects of nitrogen;

- treated plants have an increased tolerance to bound, airless, temporarily water-covered areas;

- the humus content of the soil can be maintained or increased by significant residual root residues;

- By improving the nutrient absorption capacity of plants, nutrient supply can also be increased;

- resistance to optional parasites causing necrosis is increased (eg thrush, stem fungus);

- resistance to maize moth is increased due to morphological causes (thickening of the cellulose wall);

- the value of the product changes favorably (eg bakery value, protein content);

- nutrients delivered through the leaf are better absorbed;

- the flora is more balanced;

- lower lifetime energy requirements of treated plants;

- the efficiency of photosynthesis is improved.
