“…Среди агротехнических мероприятий большое значение уделяется созданию опти-мальной густоты стеблестоя льна, влияющей на регулирование урожайности волокнистой и семенной льнопродукции в сочетании с оптимальным внесением минеральных удобрений, обеспечивающих сохранение и повышение плодородия дерново-подзолистых почв. Новые сорта, выведенные за последние годы, благодаря лучшему сочетанию хозяйственно-ценных признаков позволяют без дополнительных затрат увеличить урожайность культуры на 15 -20%, а грамотное использование их преимуществ -устойчивость к полеганию и болезням, высокое качество волокна не требуют дополнительных затрат при возделывании [2,3,4,5,12].…”

Цель исследований – показать реакцию среднеспелых сортов льна-долгунца Тонус и Надежда на агротехнологические элементы возделывания (нормы высева семян, дозы удобрения) при возделывании культуры в условиях Центрального района НЗ РФ. Исследования проводили на дерново-подзолистой среднесуглинистой слабокислой почве в Тверской области с очень высоким содержанием подвижного фосфора и средним содержанием калия. Объектами исследований являлись среднеспелые сорта льна-долгунца Тонус и Надежда селекции ОП НИИЛ ФГБНУ ФНЦ ЛК. Для данных сортов впервые выявлено сочетание нормы высева семян и дозы удобрения при выращивании на семена и волокно. У сорта Тонус для получения наибольшего урожая льноволокна (1,64 т/га) оптимальным было сочетание нормы высева 24 млн всхожих семян на 1 га с дозой удобрения N15P30K60. Для семенной продуктивности оптимальным было сочетание меньшей нормы высева – 20 млн всхожих семян на 1 га с дозой удобрения N15P30K60. Урожайность семян составила 0,89 т/га. Для сорта Надежда для получения наибольшего урожая льноволокна (1,35 т/га) также оптимальным было сочетание нормы высева 24 млн всхожих семян на 1 га с дозой удобрения N15P30K60. Для семенной продуктивности оптимальным было сочетание меньшей нормы высева – 20 млн всхожих семян на 1 га с дозой удобрения N15P30K60. Урожайность семян при этом сочетании составила 0,91 т/га. The purpose of the research is to show the reaction of medium-ripened fiber flax varieties Tonus and Nadezhda to agrotechnological elements of cultivation (seeding rates, fertilizer doses) when cultivating crops in the conditions of the Central district of the NZ of the Russian Federation. The studies were carried out on sod-podzolic medium loamy slightly acidic soil in the Tver region with a very high content of mobile phosphorus and an average content of potassium. The subjects of the research were medium-ripened fiber flax varieties Tonus and Nadezhda of the selection of the separate division of Flax Research Institute. In the Tonus variety, the combination of the seeding rate of 24 million germinating seeds per 1 ha with a dose of fertilizer N15P30K60 was optimal for obtaining the highest yield of flax fiber – 1.64 t/ha. For seed productivity, the optimal combination was a lower seeding rate – 20 million germinating seeds per 1 ha with a dose of fertilizer N15P30K60. The seed yield was 0.89 t/ha. For the Nadezhda variety, also for obtaining the highest yield of flax fiber – 1.35 t/ha, it was optimal to the combination of the seeding rate of 24 million germinating seeds per 1 ha with a dose of fertilizer N15P30K60. For seed productivity, the optimal combination was a lower seeding rate – 20 million germinating seeds per 1 ha with a dose of fertilizer N15P30K60. The seed yield in this combination was 0.91 t/ha. For the first time, a combination of the seeding rate and the fertilizer dose when growing on seeds and fiber was revealed for the medium-ripened fiber flax varieties Tonus and Nadezhda.

“…Несбалансированность элементов питания в почве неблагоприятна для льна-долгунца, т.к. для получения льнопродукции высокого качества необходимо, чтобы калий в питании растений преобладал над фосфором и азотом [2,3]. Важным элементом в технологии возделывания льнадолгунца является определение оптимальных доз удобрений.…”

When cultivating fiber flax, it is recommended to calculate the doses of fertilizers for the main application by compensating for their removal by the crop. On sod-podzolic medium-loamy soil with mobile phosphorus content from high to very high, low and medium potassium content, phosphorus must be compensated by 100% due to fertilizers, and potassium-by 120 %. The optimal dose is N15P22K80. Fiber flax

Abstract. The purpose of the research was to assess the average-ripe varieties of fiber-flax Smolensk selection on the complex of economic and useful features. The research was carried out on sod-podzolic, medium-loamy, medium-cultivated soil in the experimental fields of the Smolensk Institute of agriculture (ex. Smolensk state farm). The object of the study are 3 medium-ripe varieties of fiber-flax selection of Smolensk ISH: S-108 (on average for 2007–2009), Smolich (on average for 2011–2013) and Impul’s (on average for 2016–2018). Tab experiments, observations and records were performed according to generally accepted methods. The system of agriculture is typical for the Smolensk region. Results and practical significance. The article presents a comparative characteristic of the studied varieties of fiber-flax. It was established that all varieties belonged to the group of medium-ripened with a vegetation period of 80 days. Varieties S-108 and Impulse (80 cm) were the tallest along the length of the stem. Smolich lagged behind in growth from the above varieties on 5 sm. All varieties had a high resistance to lodging and optimal density of standing plants before harvesting. The highest yield of flax seeds and flax straw was noted in the variety S-108 (7.5 and 53.5 c/ha, respectively). The yield of all fiber varieties S-108 and Impul’s were at the same level (14.9 and 14.8 c/ha, respectively). The variety S-108 (29.0 % and 22.3 % respectively) was also distinguished by the content of all fiber in the stems and the yield of long fiber. According to the qualitative characteristics, the most durable fiber was in the Smolich variety (33.4 kg/s). The flexibility of all the studied varieties was approximately at the same level. Scientific novelty. Improvement of already existing varieties of fiber-flax with ecological plasticity.
