Improvement of the cucumber protection system in the greenhouse for production environmentally safe products
Production of environmentally friendly cucumber products is one of the important problems of modern vegetable growing. In the current situation, many issues of cucumber technology using the low-volume technology method require adjustment and further improvement. The purpose of the research was to study and assess the effect of combinations of zircon with biofertilizers against the background of the use of biological products on the growth, development, yield and quality of cucumber. The complex treatment of cucumber plants of the F1 Atlet hybrid with biologically active substances (BAS) contributed to an increase in biometric indicators in comparison with the control throughout the entire crop rotation. The period from germination to the beginning of flowering and fruiting decreased, the plant height increased by 7.2-13.2% and the stem diameter by 12.5-17.5%. The yield was significantly influenced by the growth of the leaf area of cucumber plants, which increased in variants with experimental technologies by 5.9-34%. Under the influence of the studied factors, the yield of standard cucumber production increased by 8.0-27.6%. The mass fraction of fruits that do not meet the requirements of the standard was 6.6-8.1%. On the control variant, the output of non-standard products increased to 10%. The highest net income and level of profitability were obtained with the combined use of Zircon with Ecofus, both against the background of the use of biological products (659.3 rubles / m2 or 38.4%) and without them (685.13 rubles / m2 or 40.1%).
