Application of complex micro fertilizers in protected soil

Abstract

In arid and sharply continental soil and climatic conditions of the Akmola region, green-house farming is an important technique. Greenhouse farming is one of the promising areas of agriculture, since vegetable and melon crops are grown in conditions of temperature, humidity, illumination, and nutrient medium regulated at an optimal level, which results in a high yield of fruits, vegetables and melons. In the winter industrial greenhouse of Kokshetau University, the effect of mineral fertilizers and trace elements on the growth, development and yield of cucumber was studied. As a result of two crop rotations, positive data were obtained indicating an increase in plant growth in height at the early stages of vegetation by an average of 2.20 cm with presowing soaking of seeds and non-root fertilization of plants with 0.1-0.5 % aqueous solution with preparations of biological origin Phomazin+Filvimax, an increase in leaf area by 13.5 cm2, an acceleration of the flowering phase by 1.3-1.5 days, an increase in the yield of standard fruits by 22 pcs., an increase in yield by 5.9 kg / m2. The improvement of these indicators is justified by the presence in the preparations of biological origin Phomazin+Filvimax of a significant amount of macro- and microelements that play an important role in plant nutrition and the formation of cucumber fruits. It is recommended to grow vegetables according to the developed technology in a greenhouse in the conditions of the Akmola region for uninterrupted supply of fresh vegetables to the population.
