The method of cultivating very early ripening soybean varieties of grain in the drip irrigation system allows the vital trace elements molybdenum Mo, boron B, cobalt Co, manganese Mn, zinc Zn and copper Cu to be introduced fractionally together with irrigation water into the root system according to the main periods of crop formation

Drip irrigation system at the pilot site.

When cultivating very early varieties of soybeans, we used a set of equipment for the drip irrigation system of Ortech OJSC. The drawing shows a diagram of a system for preparing water and supplying nutrients to the soil under drip irrigation. The constructed system includes hydraulically connected water source 1, a pumping station 2, a tank 3 for preparing a nutrient solution, a filter 4, pressure gauges 5, 6, 7, 8 and 9, shut-off valves in the form of valves 10-17, main pipeline 18, a distribution and irrigation network pipelines 19, 20 and individual droppers 21.

The system for preparing water and feeding the nutrient mixture relative to the irrigation pipelines 19, 20 and droppers 21 is geographically remote at a distance of 300 m.

The filter 4 for water purification from source 1 (a pond located on the farm) is made in three stages. The first stage of purification is designed to remove mineral debris, plant impurities and suspensions with a minimum particle size of up to 0.5 mm and is made in the form of a hydrocyclone 22. The hydrocyclone 22 is equipped with a self-cleaning strainer 23 concentrically installed in its cavity and a sedimentation chamber 24 for collecting pollution products. The second stage of the filter 4 provides for finer water purification and is presented in the form of a horizontally mounted container 26 filled with filtration material 25. The tank 26 is made of concentric, differently sized thick-walled pipes 27, 28. The ends of the pipes 27 and 28 are connected by plugs 29, 30 of sheet steel 16 thick -20 mm.

Filtration material 25 is presented in the form of size-calibrated sand with a grain diameter of 1-6 mm.

Alternatively, to increase the performance of the filter 4, the filter material 25 is presented in the form of layer-by-layer coarse-grained washed sand and crushed stone with a particle size of 0.5-2.0 mm, respectively, placed in a container 26 of the second stage. Dolomite crushed stone with grain sizes of 5-20 mm was used as a large aggregate. The bulk density was 1.3 tons per m ³ . The bulk mass of crushed stone was 2.62 t / m ³ . Frost resistance grade F = 200, strength - 1000-1200 kgf / cm ² (100-120 MPa). Silica sand with a fineness modulus of 2.5 was used as a fine aggregate. The content of clay and clay impurities does not exceed 1%. The grain size is 1-5 mm. In the tank 26, the upper slotted pipe 31 and the lower drainage pipes 32 are appropriately placed. The drainage pipes are mutually connected by a collector 33. The collector 33 is connected to the upper slotted pipe 31 by a riser 34 and a valve 16. The pipes 31, 32 provide water supply from the hydrocyclone 22 and filtered discharge water in the third step for final cleaning. The filter of the second cleaning stage has a network for the removal of pollution products. The upper slit pipe 31 with the lower drainage pipes 32 are connected via a valve 16 on the riser 34. The third stage of water purification is presented in the form of a slot filter 36 horizontally mounted in the housing 35. The slot filter 36 in the housing 35 of the third water purification stage is installed with the possibility of accelerated dismantling.

The tank 3 for preparing the nutrient solution and trace elements is hydraulically parallel connected to the network between the first and second stages of the filter 4, i.e. into the pipeline 37, divided into parts by the valve 14. At the inlet and outlet of the valve 14, pressure gauges 6 and 7 and valves 12 and 13 are mounted by means of nipples. The output ends of the valves 12 and 13 are connected by pipelines 38 and 39 to the sealed container 3. The cavity of the container 3 is periodically filled instant mineral fertilizers, macro- and microelements or other solutions to improve the nutritional regime of cultivated soy plants.

The filter 4 of the second cleaning stage is equipped with the ability to remove the clogging from the cavity of a horizontally installed sealed container 26. For this, the riser 34 is equipped with a valve 15 and is divided into parts by a second valve 16 that separates the upper slotted pipe 31 and the drainage pipes 32 when cleaning the water in the tank 26.

The system for preparing water and feeding the nutrient mixture has a counter 40 for the consumption of purified water. The meter 40 in the hydraulic network is mounted on the nozzle of the housing 35 behind the housing of the slotted filter 36 of the third stage of irrigation water purification before being fed into the main pipe 18. Said main pipe 18 is hydraulically connected to the distribution pipe 19 by means of a pressure regulator 41 provided with a pressure gauge 9. Between the meter 40 water and the housing 35 of the filter 4 of the third stage mounted pressure gauge 8.

Valves 10 and 11 and a manometer 5 are installed in the network between the pumping station 2 and the hydrocyclone 22. Similarly, in the hydraulic network between the hydrocyclone 22 of the first cleaning stage and the fine filter 4 of the second stage, a valve 14 is mounted, at the input and output of which a pair of pressure gauges 6 and 7 in order to control the pressure of water in the tank 3 preparation of a nutrient solution. The groups of manometers 5, 6, 7, 8, and 9 sequentially installed in the hydraulic network with the pump station working are monitoring the entire cycle of water supply and purification.

When designing the system, it was decided to equip it with drip lines of the Israeli company Matserplatz, as irrigation pipelines 21 with droppers 22, providing a flow rate of 2 l / h for each dropper. The distance between the droppers is 0.4 m, which ensures the closure of humidification loops from adjacent droppers in the soil profile. This decision was caused by the fact that the design of these drip lines is currently advanced, but the equipment available at the factory does not allow the production of similar lines.

Matserplatz droppers are semi-compensated and equipped with the simplest differential pressure compensation device in the network (labyrinth). The labyrinth is a system of numerous turns of the flow, creating turbulence in the turbulent movement of water. Turbulent processes appearing in the labyrinth slow down the movement, which makes it possible to obtain a drop outflow of 2 l / h through an opening with a diameter of 1 mm.

There is a special chamber between the labyrinth and the outlet that protects the dropper from being blocked by soil particles (mineral debris) from the outside. To protect against contamination by particles transported with irrigation water, a comb is placed in front of the maze, the passage gaps of which are already in the passage of the labyrinths. In the irrigation pipeline, the comb is fixed at a slight slope to the moving stream, which allows water to wash away all those particles that have settled on the comb.

Pollution that has passed through the piping system is brought by water to the end sections of the drip lines where it accumulates. Removing dirt is ensured by opening specially installed plugs. The frequency of flushing is determined by a combination of various factors, but for the smooth operation of the irrigation system, at least 1 flush per season is required.

Washings are most often carried out in the spring, before the start of SKO, to wash out the contaminants remaining from last year and in the fall, before preservation for the winter, to remove dirt accumulated during the irrigation period.

In order to clean the system of insoluble metal compounds, clogging irrigation lines and droppers, phosphoric acid of increased (7-8%) concentration is supplied with water. Such preventive flushing is carried out at least 1 time per year.

For very early ripening soybean varieties with a thermal regime of 1701-1900 ° C, molybdenum (Mo), boron (B), cobalt (Co), manganese (Mn), zinc (Zn) are introduced into the phase of “branching - the beginning of flowering” along with irrigation water. and copper (Cu) with norms of 60 ... 75, 18 ... 25, 30 ... 60, 15 ... 75, 22.5 ... 30 and 15 ... 25 g / ha, respectively. For complete assimilation by the roots of soybean plants during the period of “flowering - the beginning of the formation of beans” in a water-soluble form, Mo is added additionally with a norm of 80 ... 100 g / ha, B - 25 ... 35 g / ha, Co - 40 ... 80 g / ha, Mn - 20 ... 100 g / ha, Zn - 30 ... 40 and Cu - 30 ... 40 g / ha. To obtain a full-weight soybean grain during the period of “formation - the beginning of mass loading of beans” add trace elements - Mo - 40 ... 50, B - 10 ... 15, Co - 20 ... 40, Mn - 10 ... 50, Zn - 15 ... 20 and Cu - 10 ... 15 g / ha. Mo - 32 ... 40, B - 10 ... 14, Co - 16 ... 32, Mn - 8 ... 40, Zn - 12 ... 16 and Cu - 10 ... 16 are fed into the phase “bean filling - the beginning of grain ripening” together with irrigation water g / ha To increase the oil content of seeds of very early soybean varieties, Mo - 48 ... 60, B - 15 ... 21, Co - 24 ... 28, Mn - 12 ... 60, Zn - 14 ... 18, Cu are introduced in the final phase “beginning - full ripening of grain” - 9 ... 15 g / ha.

Thus, during root dressing of very early soybean varieties in the five indicated phases, zinc (Zn) 93.5 ... 124 g / ha, boron (B) - 78 ... 110 g / ha, copper (Cu) - 74 were added with irrigation water ... 111 g / ha, molybdenum (Mo) - 260 ... 325 g / ha, cobalt (Co) - 130 ... 260 and manganese (Mn) - 65 ... 325 g / ha.

Tables 1-3 show the effect of different doses of the very early ripening soybean varieties of trace elements Mo, B, Co, Mn, Zn, Cu introduced into the main phases of plant development on the yield, protein, fat, and TIA when cultivated in RMS.

The data presented show the high efficiency of fractionally introduced trace elements Mo, B, Co, Mn, Zn, Cu in the main phases of soybean plant development and in the formation of the size and quality of the crop. The described method of introducing trace elements into the root system together with irrigation water SKO allows reducing the consumption of expensive trace elements by 2–3 times and significantly increasing soybean yield.

Thus, the claimed method of cultivating very early varieties of soybeans for grain in the North Kazakhstan region ensures the achievement of the specified technical result.
