Manufacturing of plant protective machines in Perla - Nova Zagora
Keywords:
Perla; plant protection machines; sprayersAbstract
A thorough analysis of the development of plant protection equipment in the Perla plant, Nova Zagora, Bulgaria in the past 60 years was carried out. In the 1960s, with huge efforts and despite the low level of machine building, high-level sprinklers were produced at the Perla plant on high level for the socialist camp, and on average level for the Western European countries. Some technical solutions, unfamiliar to Western producers, have realized in the production of these machines. Insufficient research in this direction did not allow machines to be widely applied in practice despite of their advantages. Experience has shown that the introduction of new technologies unknown to our country can not only be achieved through the manufacture or import of suitable machines. This can only be a necessary requirement but not enough. For a plant protection machine, in order to be on a high level, it is advisable in its production to use elements and systems of leading manufacturers.
