During the period of the lambing campaign, two groups of queens with sheep aged 30 days were formed in the flock of sheep. Lambs were selected according to the method of analogues of 20 heads in each group. For separate feeding of lambs inside the sakman cages made of wooden shields, \"canteens\" with an area of 15 m2 were equipped. The prebiotic drug \"Kormomix-MOS\" is 5 g per head per day for 30 days. Its positive effect on the increase in live weight and meat productivity has been established. According to the live weight, the superiority of the animals of the experimental group over the control ones was 1.95 kg or 5.6% (P>0.999). The experienced animals had the best meat qualities. According to the pre-slaughter weight, the excess was 5.2%, according to the mass of chilled carcasses, the advantage was 1.16 kg (8.3%), respectively. The lethal yield was also 42.2 % in the experimental group, and it was 41.13% in the control group, respectively. The analysis of the yield of cuts by varieties also indicates that in the carcasses of animals of the II experimental group, the yield of first – class cuts-hip, lumbar and shoulder-spinal, was greater than in the control ones by 0.5%. In terms of morphological composition, the carcasses of group II sheep exceeded the control in terms of the yield of edible parts (pulp) by 0.91%, the meat content coefficient - by 0.06 and the area of the muscle eye – by 0.21 cm2 or 2.1%. When cutting carcasses into anatomical cuts, the advantage of experimental animals over control animals was also established. The average shoulder-spinal cut in the group of experimental animals was 6.57 kg, and the hip cut was 4.29 kg, which exceeded the control ones by 8.2% and 8.9%, respectively. No significant differences were found for the remaining cuts. The mass of the internal organs of the experimental animals was generally greater than that of the control animals, but there was no statistical difference.","PeriodicalId":14015,"journal":{"name":"International Journal of Life-Sciences Scientific Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76280560","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This is manifested, first of all, with the underdevelopment of industry and shortcomings in the technologies for the development of agriculture. Considering one of the activities in agriculture, namely rice growing, it is worth noting that relatively recently, in the 80s of the last century, the Kuban, as one of the constituent entities of the Russian Federation, achieved maximum success in the development of irrigation systems for rice cultivation. But at this time, there is enough area for rice cultivation to meet both internal and external needs, which is good news, but at the same time another problem arises related to the constant decrease in water resources. Accordingly, the timely elimination of problems in the irrigation system will lead to the improvement of the irrigation system. The challenge is to reduce unnecessary water loss during irrigation in rice cultivation. The economic support for the maintenance of irrigation system technology in Russia leaves much to be desired. Because of this, in numerous cases, individual parts of the irrigation system are subject to repair, but not the reconstruction of the main canals, or even the construction of new systems. The article deals with modern issues of monitoring the technical condition of the Kryukovskaya irrigation system of the Abinsk region using laser scanning methods. The results of the use of unmanned aerial vehicles to improve the monitoring of the technical condition of the elements of irrigation systems are presented. Today, the Federal State Budgetary Institution \"Kubanmeliovodkhoz Administration\" does not have the technical capabilities and resources as in the 70-80s of the last century, but at the same time, responsibility has only increased over the years, both pumping stations, mechanical equipment, partitioning structures, as well as inter-farm and on-farm channels. Many elements need to be replaced, as they have exhausted their operational resource, designed for thirty years of operation. Irrational organization of water management leads to significant losses of water, energy and material and technical resources. The stages of using modern unmanned aerial vehicles for examining the elements of irrigation systems are considered.","PeriodicalId":14015,"journal":{"name":"International Journal of Life-Sciences Scientific Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76422686","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Issues of thermal fatigue strength are especially relevant for such heat-stressed parts of internal combustion engines of autotractor diesel engines as the cylinder head. Of particular importance for these parts in their design and restoration is the ability to predict thermal fatigue strength, which is the main criterion that determines their durability. The article describes an approach to solving the problem of predicting the thermal fatigue strength of cast iron parts based on the data on their stress state and the results of thermal fatigue testing of samples on a specially designed and manufactured installation. The setup consists of two massive plates mounted on racks, between which a sample with a hole was rigidly installed. During the tests, the sample was heated by a special annular furnace to a temperature of 550°C for two minutes, and then cooled with running water through the central hole. A sample bounded on both sides during heating and thermal expansion accumulated residual tensile stresses as a result of relaxation processes and, upon reaching critical values and the appearance of fatigue defects in the form of cracks, ruptured. The proposed mode quite accurately repeats the operating conditions of the heat-receiving surface of the cylinder heads in the area of the intervalve jumpers when changing the operating mode at rated power and subsequent engine shutdown. As a result of the tests, the curves of the number of cycles to failure depending on the achieved stresses were obtained and their approximation was carried out. On the basis of approximating expressions and dependences of \"limited durability\" under low-cycle loading of parts, the thermal fatigue strength of a part made of cast iron can be predicted when its stress state changes as a result of design changes or after restoration.","PeriodicalId":14015,"journal":{"name":"International Journal of Life-Sciences Scientific Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82626366","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Analytical dependences were derived reflecting the influence of the design and technological parameters of the proposed design of the cultivator on the resistance of tillage. To confirm the possibility and adequacy of the application of the presented dependences, laboratory and field studies were carried out. The studies were carried out in accordance with the requirements of GOST 20915-2011, GOST 33687-2015, GOST R 54783-2011. For these purposes, a design was developed that imitates the proposed design of the cultivator. In the course of laboratory studies, it was found that with an increase in the depth of tillage with the right- and left-sided flat-cutting paw of the cultivator, there is a sharp increase in the resistance of tillage and at a tillage depth of 4 cm, the increase was 56.7%, at a depth of 6 cm - 39.1% ; 8 cm - 28.9%; 10 cm - 24.1% and 12 cm - 20.4%. Increasing the speed of tillage by the cultivator of the proposed design also leads to an increase in the resistance of tillage. It was found that by increasing the soil tillage speed to 1.8 m/s, an increase in soil tillage resistance up to 9.4% was recorded, and a further increase in tillage speed leads to a higher increase in soil tillage resistance up to 23.5%. Conducted field tests fully confirmed the results of theoretical and laboratory studies. The comparison of the results of soil tillage resistance performed by the serial cultivator KPS-4.0-0.2 found that it is 9.8% higher compared to the cultivator of the proposed design. This circumstance allows us to conclude that the use of a cultivator with right- and left-sided flat-cutting paws is effective in tillage.","PeriodicalId":14015,"journal":{"name":"International Journal of Life-Sciences Scientific Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83333650","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of the research was a comparative assessment of the adaptability of the mass of 1000 seeds of collection samples of field peas. The tasks were set to determine the indicators of adaptability of samples by the weight of 1000 seeds: ecological plasticity (bi), homeostaticity( Nom), coefficient of adaptivity (KA), coefficient of multicativity (KM), stability indicator (PUSS); by ranking the obtained indicators, to determine the most adaptive samples of field peas by the mass of 1000 seeds in the conditions of the East Siberian forest-steppe; to determine the variability of the studied indicator by years and to identify correlations of the mass of 1000 seeds with the indicators of adaptability. As a result of the study, it was revealed that in most cases, the adaptive abilities of field peas were higher than those of the standard-field peas, which allows us to recommend Pisum arvense L. to attract Pisum sativum L. to hybridization during breeding. in order to increase the adaptability of the indicator, the weight of 1000 seeds.

There are also requirements for reducing the construction time of these facilities, and improving the efficiency of agricultural production on reclaimed lands. The creation of modern reclamation systems needs to clarify the traditional methodological approaches to solving a number of problems. In reclamation construction, closed irrigation systems are becoming increasingly widespread, the main elements of which are: a stationary or mobile pumping station, a closed irrigation network and sprinkler equipment. The experience of operating modern closed irrigation systems has shown that due to changes in the operating modes of pumping stations and sprinkler equipment, sharp pressure fluctuations (hydraulic shocks) occur in pipelines during certain periods, which can lead to network destruction, failure of pipeline valves and pumps. Hydraulic engineering and reclamation facilities must meet certain requirements for reliability and environmental safety. First of all, this is achieved by protecting pipelines from an unacceptable increase in pressure that occurs during hydraulic shocks caused by changes in the operation of pumping units. Damage and accidents in the pressure systems of a closed irrigation network can also occur during transients that occur when pumping units are started up in accordance with the work schedule. The purpose of the work is to clarify the calculation justification, design and safe operation of closed irrigation systems with pumping stations.","PeriodicalId":14015,"journal":{"name":"International Journal of Life-Sciences Scientific Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85299021","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It was revealed that the development of multicomponent organic fertilizers based on nanostructured diatomite and organic waste and raw materials processing products is an effective direction for the development and dissemination of organic farming technologies, especially in the conditions of increasing aridity of the growing season. Multicomponent fertilizer - an organic complex feed with the function of a soil enhancer based on diatomite - reduced the involvement of winter wheat plants with root rots by 12.7-29.7% compared to the control, and by 6.0-8.0% compared to mineral fertilizer. The yield of winter wheat in organic fertilizer was inferior to the productivity in mineral - by an average of 0.9-6.5%, with the cost of introduced mineral fertilizer of about 2000.00, and organic - 1710.00 rubles/ha. The greatest yield was achieved on the variant with mineral fertilizer on the background with biologics - 23.8% more control, but only 0.9% more than the variant with organic fertilizer.

The study of soil extracts by the method of polarization curves showed that leached chernozem is more corrosive than ordinary chernozem and dark chestnut soils. Additives to soils with mineral fertilizers increase their corrosive aggressiveness, especially in the presence of moisture. The rate of corrosion in soil extracts in the presence of ammonium nitrate is 10-15% higher than in the presence of azophoska, superphosphate, and urea.
