The studies were carried out in the southern part of the Arkhangelsk region (Kotlas region). Yellow water traps were used to catch winged aphids. It was revealed that 25 species of winged aphids migrate to potato plantations with an average annual number of 162 individuals during the growing season. Of the total number, 7 species of aphids carrying potato viruses were identified. These included Acyrthosiphon pisum Harr., Aphis fabae Scop., Aphis nasturtii Kalt., Aulocarthum solani Kalt., Hyperomyzus lactucae L., Macrosiphum euphorbiae Thomas, and Rhopalosiphum padi L. These species account for 70 to 82% of the abundance structure. Not a single individual of the most harmful species Myzus persicae Sulz was caught. In the group of virus-carrying aphids, the most numerous species are R. padi L. (an average of 48 individuals per season) and A. fabae Scop. (an average of 35 individuals per season). It has been established that the flight of aphids is largely influenced by average daily air temperatures. In the conditions of the hottest year (2021) at an average daily air temperature of 19 °C, the largest annual number of aphids was identified - 181 individuals. Winged aphids are present in potato agrocenoses throughout the entire growing season, which indicates the need for annual monitoring of their numbers and the use of protective measures.","PeriodicalId":219145,"journal":{"name":"The Agrarian Scientific Journal","volume":"76 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128711942","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 active development of the transport system requires high-quality roads, as this affects the safety of their operation and especially during low temperatures. During this period, roads are covered with ice or snow, which requires their speedy removal. The quality of the road surface depends on the adhesion of ice with road clothes. The article deals with the issue of adhesive interactions in the ice-asphalt concrete system. The developed methodology can determine the adhesion of ice to the surface of the road surface. This circumstance will allow using various additives and varying the composition and components of asphalt concrete to reduce adhesive interactions. Reduced adhesive interactions will allow to remove ice and snow more quickly, and this will reduce the number of road accidents, which will save people's lives and health. Bituminous salt mass, which is a waste from the destruction of chemical weapons of the organophosphorus group, is considered as modifiers. Its chemical composition is considered, which makes it possible to ensure its effect of surfactants. The experiments were performed and processed using the theory of experiment planning. The response surfaces of a particular sample of the general population and the regularities described by regression equations, the adequacy of which is verified by the Fisher and Cochrane criteria, are obtained.","PeriodicalId":219145,"journal":{"name":"The Agrarian Scientific Journal","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125176678","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 main feeding ration of young animals of the first experimental group additionally included 50 g/head of the feed additive «Ippomin Junior» and the second experimental group 175 g / head of the feed additive «Ippovit». The use of vitamin and mineral complex «Ippomin Junior» and «Ippovit» allowed to balance the level of macro- and microelements, as well as vitamin D in the feeding diets of young horses to the recommended feeding standards. In addition, a biochemical blood test also showed normalization of the main indicators that do not exceed the permissible limits, which indicates an improvement in metabolism when using vitamin and mineral complexes. The best growth and development indicators were established in the experimental groups. In the first experimental group, the height at the withers increased by 3.4%, in the second experimental group – by 3.5%, in the control group – by 1.3%; oblique trunk length by 6.3%, 4.1% and 1.8%, respectively; chest circumference – by 4.0%, 3.9% and 2.4%, respectively; pastern girth in young animals in the experimental groups by 2.4%, in the control group – by 1.4%.

Varieties of folk selection persimmons with the best biochemical parameters have been identified: ZU-01, ShG-01, ShG-03, ZM-01, BA-01, BA-02 and ZM-01. The dependence of the content of vitamin C and sugars in fruits on the height of collection points was revealed. It has been shown that with an increase in the height of the collection points, the content of sugars and vitamin C in fruits decreases. According to the data obtained, the varieties growing at an altitude of 200–300 m above sea level differed in the highest content of vitamin C: BA-02 (39,60 mq/%), BQ-01 (39.80 mq/%), ShG-03 (39.70 mq/%) и BA-03 (38.00 mq/%); the lowest – growing at an altitude of 600–800 m above sea level: QN-01 (28.38 mq/%), QN-02 (28.40 mq/%) и QV-02 (29.00 mq/%). The highest sugar content in fruits was found in forms growing at an altitude of 200–500 m above sea level: ShG-01 (23.00%), ZU-01 (23.00%), ShB-01 (22.00%), ShG -03 (22.00%) and BA-01 (22.00%). The lowest indicators of sugars were recorded in persimmon varieties of folk selection QN-02 (17.00%), QZ-04 (17.00%), QV-01 (18.00%), QN-01 (18.00% ), QZ-03 (18.00%), growing at an altitude of 500–800 m above sea level.","PeriodicalId":219145,"journal":{"name":"The Agrarian Scientific Journal","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115771167","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}
