Біотехнічна система лазерної обробки насіння соняшнику

Abstract

It is inprocess shown that preseed electrophysics stimulation of seed and research of the technological modes for optimal influence on sowing material are actual. The aim of work is an increase of sowing internalss of seed of sunflower on the base of application of laser optical radiation. The methods of preseed stimulationof seed of oilbearing cultures and basic mechanisms of influence of stimulant factors are considered on the germination of seed. It is set that one of the most effective methods of preseed treatment of seed of sunflower is the use of laser irradiation. The aim of experimental researches was determination of parameters of preseed laser irradiation of seed of sunflower, resulting in the maximal stimulant affecting sowing internalss at the minimum charges of energy and maximally possible productivity. For realization of researches the seed of oilbearing cultures that occupy most areas on territory of Ukraine (a sort is "Hybrid") were used. Seed answered the first reproduction on sowing internalss. For the receipt of seed with mionectic sowing internalss, with the purpose of search for them optimal modes of preseed irradiation the known method of the artificial aging was applied. Determination of sowing internalss of seed was conducted for experience parties to the irradiation, and also after an irradiation with further selfcontrol in 67 days. In all cases determination of sowing internalss was conducted on standard methodology, here seedgerminating for all cultures was conducted at a temperature 2030°With illumination on a method "on a paper". Paper napkins, that were checked for accordance of indexes of the capillary getting up, acidity and ashcontent, were thus used. Tests in both cases were taken away in 2 parties for 30 seed each.A complete factor experiment is conducted on determination of parameters of preseed laser irradiation of seed of sunflower, the laboratory germination of seed is set. Results of determination of the modes of preseed laser impulsive irradiation of seed of sunflower. The biotechnical system of their treatment is worked out. The method of determination of parameters of the technological modes of preseed impulsive laser irradiation of seed of oilbearing cultures is offered depending on the initial sowing internalss of planting-stock. Dependences of germination and force of germination of seed of sunflower are set on the parameters of the technological modes of laser irradiation. The biotechnical system of laser treatment of seed of sunflower is worked out, that allows to promote the sowing internalss of seed and productivity of this culture. Key words: laser radiation, biotechnical system, sowing internalss of seed, complete factor experiment, sunflower, control system, factors of varying, pre-sowing treatment
