Описание практики и ее результаты | Actions: Deployment of the Simultaneous Impulse Sprinkling Kit (KSID-10S) allowing extremely uniform and simultaneous dispersion of irrigation water across all sections of arable pasture or hayfield meadow. Water expenditure at the impulse device makes 0.05-0.3 l/sec and 0.25-2.0 l/sec in the irrigation pipeline, thus, reducing (3-4 times) the costs associated with the pipeline network installation compared to other sprinkling systems (kits). The pipeline network is built of 15-25 mm diameter pipes easy to transport and assemble in mountainous conditions. Technical characteristics: Operation modes: automatic and manual Irrigated area: 10 ha Water consumption: up to 100 m3/day Average sprinkling (rain) intensity: 0.002-0.008 mm/min EFFICIENCY: 99% MOC: 98% Watering automation level: 100%

In 1980, specialists of NPO SANIIRI (Research and Development Association “Central Asian Research Institute of Irrigation”) designed and for the first time applied this type of drainage in the Qarshi Steppe where it demonstrated its efficiency. The project was suspended due to lack of funding. The re-launch of the project and installment of a combined drainage system in Kuva District (2010) once again confirmed its high efficiency and profitability, especially in areas of confined underground waters. Further on, the model was applied in Rishtan, Altyarik and Baghdad Districts where it is successfully working. Actions:
Results: Financial and economic: Specific construction costs (sum/ha) of the combined drainage system were twice less compared to horizontal drainage models. Vertical drainage of 1 hectare of land requires 700-800 kWh of energy, whereas the combined drainage is hyperpiestic. Maintenance costs for combined drainage systems are also much lower compared to horizontal and vertical drainage models – specifically, twofold less than for closed horizontal and threefold less for vertical. The combined drainage systems also allowed increasing crops productivity. Technical: The reclamation condition of farm land has improved. |
Какие уроки и рекомендации можно извлечь из практики | Lessons learnt: The advantages of impulse sprinkling irrigation were confirmed by the research efforts on other test sites of KAZNIIVKh in Jambyl Region that allowed increasing biological productivity of Golden Delicious apple variety by 10.1-36.8%, and commercial productivity – by 16.6-49.4% compared to conventional sprinkling irrigation systems. Recommendations: It is necessary to continue application of similar practices in foothill areas in Central Asia subject to power supply shortages. |
Lessons learnt: The practice has confirmed its high efficiency and profitability of combined-type drainage, especially in areas with confined underground water. Recommendations: It is necessary to widely apply combined-type drainage where hydro-geological conditions allow it. |
