To obtain high yields of potatoes, plant growth and development regulators of various origins are used. Recently, the use of chemicals made from natural raw materials has become more widespread. One of them is the chemicals Relict based on humic and fulvic acids, which have growth-stimulating adaptogenic and protective properties from peat. It is used both for treatment of tubers before planting, and for vegetative plants treatment. Such treatment allowed to reduce the sparseness in potato plantings, and also contributed to an increase in the yield of large and medium fractions of tubers. The marketability of tubers in the control is 81.7%, and in the areas treated with Relict is higher - at a concentration of 0.01 % - 91.6 %, and by 0.05 % - 93.7 %.
The work is devoted to the theoretical determination of kinematic parameters of a nightshade fruit separator both in direct and reusable way. The article has a research character, which is expressed in the fact that theoretically the analysis of kinematic parameters of a fruit separator, as well as works of leading scientists on the problem, their shortcomings and ways of solving these problems are indicated. There was determined the main trend of theoretical research. There were also justified the type of the proposed design, its theoretical description and the flow of the technological process. As a result of the work done, the design of the device for reusable harvesting of tomatoes and nightshade vegetables with the proposed working bodies is presented. The conclusions present the main results achieved so far.
Tomatoes play a leading role in providing the population of Russia with vegetable products, which is due to their high productivity, good taste properties, diverse use, ability to cultivate in open and closed ground, and, consequently, to consume them all year round. Based on the fact that the consumption of tomatoes is growing every year, the main task is to increase the yield and quality of fruits. One of the ways to solve this problem is, according to research data, four-fold treatment of tomato plants in the phase of milk ripeness with Esfon at a dose of 1.0l/ ha, which is due to obtaining a high yield of good quality fruits (6,204 kg/m2, in the control - 5,108 kg/m2, HCR05 = 0.250 kg/m2) and a reduction in the maturation period, in comparison with the control, is 14 days.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
