Features of the technology of growing Allium ursinum L. in Ukraine
(CEP USM, 2024) Pryvedeniuk, Nazar; Hlushchenko, Lyudmyla
The possibility of growing Allium ursinum L., in the field conditions of the left bank forest-steppe of Ukraine has been established. Studies have been carried out to establish the influence of the density of Allium ursinum L., planting on the yield of dry leaves. A tendency to increase crop productivity with an increase in planting density has been revealed. The highest yield of dry raw materials among the studied variants was obtained with a planting density of 444 thousand plants/ha.
SOLUȚIE TEHNICĂ PENTRU REPRODUCEREA ÎN MASĂ A INSECTELOR BENEFICE
(CEP USM, 2023) Gorban, V.; Gavrilița, Lidia
The device made in this work refers, in particular, to devices for the mass reproduction of beneficial insects, and can be used for the growth of parasitoids (eggs, larvae, imago). The technical solution represents a device made in the form of a vertical cylinder. Holes drilled in the lower part of this cylinder, are covered with capron mesh with smaller cells than the size of the breeded insects. The air periodically pumped by a fan, ensures an uniform air circulation throughout the section of the maintenance chamber. The biological material is attached on tapes with labels. Later, these tapes are loaded into the maintenance room and fixed on the support in a vertical position, so that the optimal conditions for the development of insects can be ensured.
