Abstract

The article provides data on the development of a complex Palodelatel unit without damaging growing plants, the simultaneous rate of a transverse surface and a longitudinal ridge in saline, sloping uneven soils in the Bukhara region, also taking into account the slope and unevenness of the soil relief, in a scientifically based form it is stated about the uniform provision of irrigation water and reduction of manual labor, working time, duration and distance between irrigation days, saving spent irrigation water and elimination of salt spots and reducing the cost of irrigation water by 25%, irrigation duration by 1.5-2 days, crop addition by 5-4.2 c / ha.

Highlights

Over the past 10 years, especially in desert and saline soils, global climate change and extreme air temperatures, from the 2nd decade of May to the 1st decade of autumn, there are hotter and longer hassles, and with a lack of water, for growing high-quality crops has some problems
The depth of groundwater, which in this area is 3 m, the soil is slightly saline, in terms of the mechanical composition of soils, medium and 2-experimental field was located in the Bukhara region, Tashkent Institute of Irrigation and Mechanization of Agricultural Engineers of the Bukhara branch, Kagan training field site, studied by comparing the control option with the use of a complex unit, the simultaneous rates of the transverse floor and longitudinal ridge in areas with increased salinity and heavy soil texture, in the cotton variety Bukhara-8
The soil and climatic conditions Bukhara region irrigations during the growing season of cotton are determined depending on the temperature of the air, mechanical soil composition, characteristics, and variety, and reclamation zone, preferably in the period of budding soiling of fertilizers necessary, i.e., at this stage field prepared they are to watering

Summary

Introduction

Over the past 10 years, especially in desert and saline soils (in the Bukhara oasis), global climate change and extreme air temperatures, from the 2nd decade of May to the 1st decade of autumn, there are hotter and longer hassles, and with a lack of water, for growing high-quality crops has some problems. The use of intensive methods of agricultural production, first of all, the introduction of modern water and resource-saving technologies" is one of the most important tasks [1, 2]. In this regard, conducting scientific research to identify the effectiveness and use of water and resource-saving integrated aggregate - simultaneous rates of the transverse surface and longitudinal ridge on saline and uneven fields of agricultural crops for uniform and economical distribution of irrigation water and elimination of saline spots, obtaining high and high-quality cotton yields - raw materials and other crops, cotton complex, is very relevant. Considering that several tasks and factors to a certain extent affect the yield and its quality, it is important how to organize irrigation, efficient use of water, and resource-saving innovative technologies in the irrigation system are one of the most pressing issues [9,10,11]
