3The role of modern technologies in improvement of increasing the greenhouse-farms crops products,

— one of the most important goals of scientific research communities is utilization of modern technologies in order to achieve high industrial systems and applications in human daily life. The growth rate of the human population and the food crisis are primarily causing global growth in using high technologies in the food industries and agricultural productions. Therefore, optimizing the cultivation conditions, managing and fighting with garden pest are very important. This may be accomplished with using high tech air ionization supplies in the greenhouses or big gardens/farms. Injection of negative ions into the air can be improved the quality and quantity of agricultural products by this equipment i.e., NGI (Negative Ion Generator). In this paper, it is shown that based on corona discharge air ionization in the greenhouses or around the trees in the gardens can be fixed some of the agricultural problems by using this method.
