Ретроспективный анализ метеорологических условий и валовых сборов озимой пшеницы стандартными методами корреляционного и регрессионного анализа.

Выявлено шесть совместных вариаций временных рядов результативных (валовый сбор зерна) и факторных признаков (гидротермические условия периодов вегетации и структурные показатели посевов) со средней и высокой теснотой корреляционной связи, выраженной в виде уравнений множественной регрессии.</p></sec><sec><title>Заключение</title><p>Заключение. Результаты проведённых исследований свидетельствуют о тесной прямой связи валовых сборов зерна с урожайностью с уборочной площади (r = 0,79), в свою очередь обратно зависимой (в средней степени) от суммы активных температур воздуха всего периода от посева до уборки (r = 0,64). Из осадков различных периодов вегетации преимущественное прямое влияние на урожайность зерна оказывают осадки холодного периода года (r = 0,49) и всего активного периода вегетации от начала парования до уборки (r = 0,39). Влияние сумм осадков за отдельные короткие периоды вегетации значительно ниже. В сложившихся условиях стабильность производства зерна озимой пшеницы будет определяться адаптивностью агротехнологий к повышающейся засушливости климата, значительно ухудшающей влагообеспеченность растений.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim. The aim of the research was to determine the relationship of winter wheat grain yields with meteorological parameters, the determination of the dynamics and current level and the selection and scientific justification of adaptive agricultural technologies.</p></sec><sec><title>Material and Methods</title><p>Material and Methods. Retrospective analysis was undertaken of meteorological conditions and gross winter wheat harvests by standard methods of correlation and regression analysis. The strength of the connection between the data of individual arrays was determined, as well as the identification of joint variation of productive and factorial features by pairwise comparison of their time series.</p></sec><sec><title>Results</title><p>Results. Six joint variations of time series of productive (gross grain harvest) and factorial features (hydrothermal conditions of vegetation periods and structural indicators of crops) with medium and high closeness of correlation, expressed in the form of multiple regression equations, were revealed.</p></sec><sec><title>Conclusion</title><p>Conclusion. The results of the studies indicate a close direct relationship between gross grain harvest and yield from the harvesting area (r = 0.79), which in turn is inversely dependent (to an average degree) on the sum of the active air temperatures of the entire period from sowing to harvesting (r = 0.64). Из осадков различных периодов вегетации преимущественное прямое влияние на урожайность зерна оказывают осадки холодного периода года (r = 0.49) и всего активного периода вегетации от начала парования до уборки (r = 0.39). Of the precipitation of different periods of vegetation, the predominant direct effect on grain yield is exerted by precipitation during the cold period of the year (r = 0.49) and the entire active period of vegetation from the beginning of fallow to harvest (r = 0.39). The effect of amounts of precipitation for certain short periods of vegetation is much lower. Under current conditions, the stability of winter wheat grain production will be determined by the adaptability of agricultural technologies to the increasing aridity of the climate, which significantly worsens the moisture supply of plants.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>Оптимизация природопользования</kwd><kwd>климатические изменения</kwd><kwd>влагообеспеченность посевов</kwd><kwd>озимая пшеница</kwd><kwd>методы адаптации</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Nature management optimization</kwd><kwd>climate change</kwd><kwd>water availability of crops</kwd><kwd>winter wheat</kwd><kwd>adaptation methods</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Исследование выполнено в рамках НИР ОФИЦ УрО РАН (ИС УрО РАН) «Проблемы степного природопользования в условиях современных вызовов: оптимизация взаимодействия природных и социально-экономических систем», № ГР АААА-А21-121011190016-1.
