The article presents the results of many years of research on the effect of foliar dressing with complex fertilizers and humate on photosynthetic activity and productivity of potato plants of Gala and Latona varieties. The following options have been studied: 1) without treatment (control); 2) dressing with Ekorost humate at a dose of 0.2-0.4 l/ha; 3) dressing with micronutrient Strada N at a dose of 3-5 l/ha; 4) dressing with micronutrient Strada R at a dose of 3-5 l/ha. The treatment was carried out twice during the growing season: when full shoots appeared and 14 days after the first one. Determination of the leaf area and calculation of the photosynthetic potential were carried out according to the VNIIKH method (1967) three times during the growing season in the following phases: budding, flowering, and the beginning of withering away of lower leaves. The crop was harvested by the method of continuous harvesting of the accounting area of the plots with weighing. The effectiveness of the studied agrotechnical methods has been proved. The best variant of the investigated ones is the use of Strada R. The plants of this variant formed a more powerful assimilation apparatus and had the highest photosynthetic potential, which ultimately affected the yield of tubers. The increase in the yield of two varieties of potatoes was 21.8-23.1 % in relation to the control. Gala variety turned out to be more responsive to the action of vegetative treatments in comparison with Latona variety.
Целью работы явились теоретические и практические разработки по системному применению органических удобрений и мероприятий для поддержания бездефицитного баланса гумуса в севообороте, представляющие научно-прикладной интерес для повышения эффективности растениеводства. Органические удобрения являются одним из основных средств производства Российского земледелия, средством, получаемым из собственных источников, которые уже в течение нескольких столетий улучшают плодородие почвы и повышают её продуктивность. Они играют решающую роль в поступлении органических и питательных веществ в почву. В современном земледелии постоянно осуществляется воспроизводство всех показателей плодородия почв до приведения их в состояние, близкое к параметрам модели плодородия для данного типа и вида почв. Однако первостепенное значение принадлежит воспроизводству наиболее важных из них. Таким важным интегральным показателем является наличие в почве сельскохозяйственного назначения органического вещества гумуса. Оно в этом случае рассматривается как вещественно-энергетическая и структурно-экологическая основа плодородия почвы. Эффективное развитие земледелия неразрывно связано с системным применением удобрений и постоянным совершенствованием технологий их внесения при возделывании сельскохозяйственных культур. Для решения этой задачи предлагается разработанная авторами методика применения органических удобрений в системе задач по производству продукции растениеводства и мероприятий для поддержания бездефицитного баланса гумуса в севообороте. При составлении баланса питательных веществ учитываются дозы внесения органических удобрений и вынос по основной удобряемой культуре. Приводятся схема по балансу питательных веществ с использованием удобрений в севообороте, а также классификационная характеристика качества навоза и химический состав соломы. В выводах показано, что основным показателем эффективности питательных веществ является количество валовой продукции, полученной от действия удобрений.The aim of the work was the theoretical and practical development of systematic use of organic fertilizers and measures to maintain a deficit-free balance of humus in crop rotation-those of scientific and applied interest to improve the efficiency of crop production. Organic fertilizers are one of the main means of production of the Russian agriculture, the means received from own sources which within several centuries improves fertility of the soil and increases its productivity. They play a crucial role in the flow of organic and nutrient substances into the soil. In modern agriculture is constantly carried out reproduction of all indicators of soil fertility to bring them into a state close to the parameters of the fertility model for this type and type of soil. However, the reproduction of the most important of them is of paramount importance. Such an important integral indicator is the presence in the soil of agricultural organic matter humus. In this case it is considered as a material-energy and structural-ecological basis of soil fertility. The effective development of agriculture is inextricably linked to the systematic use of fertilizers and the continuous improvement of technologies for their application in the cultivation of agricultural crops. To solve this problem, the authors propose a method of application of organic fertilizers in the system of tasks for the production of crop production and measures to maintain a deficit-free balance of humus in crop rotation. When drawing up the balance of nutrients, the doses of organic fertilizers and the removal of the main fertilized culture are taken into account. The scheme on the balance of nutrients with the use of fertilizers in crop rotation, as well as the classification characteristics of the quality of manure, and the chemical composition of straw are presented. The conclusions show that the main indicator of the effectiveness of nutrients is the amount of gross output obtained from the action of fertilizers.
The article evaluates the effectiveness of the use of Aquarin, sodium humate, Epin and Zircon in the production of flax products. The use of these preparations was studied for topdressing of plants during the growing season and in the process of retted stalks maturation. Topdressing of crops was carried out in the phase of “rapid growth”. The processing of the fiber flax ribbon was carried out on the fifth day after pulling. The greatest efficiency in spraying fiber flax crops and processing retted stalks was shown by the combined use of Aquarin and Humate “Fertility”. The combined treatment of crops with Aquarin and a humic preparation provided an increase in all production indicators: straw yield increased by 11.6 %, seeds by 24.8 %, retted stalks and fibers by 4.6-6.2 %, and scabbard fiber by 44 %. The treatment of flax ribbon with micronutrient fertilizer Aquarin together with Humate “Fertility” led to an increase in the fiber yield by 5.1 %, the long fiber yield by 2.4 %, and the fiber strength by 0.35 Dan. The data obtained make it possible to recommend the use of preparations both during the growing season and in the process of retted stalks maturing to increase the efficiency of fiber flax production.
The article examines the effect of foliage spraying with complex micronutrient fertilizers Strada N, Strada R and humate Ekorost on the preservation of potato tubers of Gala and Latona varieties. The data on natural loss and total quantitative losses of experimental and control tubers after eight months of storage are given. A decrease in the natural loss of mass and absolute waste of tubers in the variants with the use of complex micronutrients has been revealed. Micronutrient Strada R with predominating phosphorus had the greatest effect on increasing the preservation of tubers. It is shown that the use of Ekorost humate does not have a pronounced effect on increasing the storage capacity of tubers, although it leads to a slight decrease in the natural loss of mass of two potato varieties.
