ВЛИЯНИЕ БИОЛОГИЧЕСКИ АКТИВНЫХ ПРЕПАРАТОВ НА ПРОДУКТИВНОСТЬ И КАЧЕСТВО ПЛОДОВ ПЕРЦА СЛАДКОГО В УСЛОВИЯХ ИНТЕНСИВНОЙ СВЕТОКУЛЬТУРЫ

Effects of humic preparation (HP) Stimulife and PGPR (plant growth promotion rhizobacteria) Bacillus subtilis №2 on the productivity and quality of the sweet pepper (Capsicum annuum L.) fruits were studied in the control conditions. It was experimentally established that the use of Stimulife and bacteria Bacillus subtilis №2 resulted in an increase in plant height, productivity and biochemical composition of sweet peppers. Differences in the effect of the studied preparations on the morphometric, phenological and biochemical characteristics of plants and fruits of pepper varieties Ermak and Cinderella were revealed. The bacteria Bacillus subtilis №2 significantly increased the yield, the number of fruits per one plant and the contents of ascorbic acid and carbohydrates in pepper fruits. In this case, the average weight of one fruit of pepper v. Ermak decreased. HP Stimulife increased the pepper yield due to increasing the mean mass of one fruit in both pepper varieties. Joint used of HP Stimulife and bacteria Bacillus subtilis №2 led to an intensification of the production process of plants compared to the experiment variants, in which HP Stimulife was used alone. The yield of sweet pepper Ermak and Cinderella increased by 10-45%, the maturation period of fruits was reduced by 10-14 days, the content of ascorbic acid increased by 25%, sugar content increased to 26%. The expediency of the joint application of HP Stimulife and bacteria Bacillus subtilis №2 in the cultivation of sweet pepper under controlled conditions is substantiated.В условиях интенсивной светокультуры изучено влияние гуминового препарата (ГП) Стимулайф и PGPR бактерий Bacillus subtilis №2 на продуктивность и качество плодов перца сладкого Capsicum annuum L Экспериментально установлено, что применение ГП Стимулайф и бактерий Bacillus subtilis №2 привело к увеличению высоты растений, показателей продуктивности и улучшению биохимического состава плодов перца сладкого. Выявлены различия в действии изучаемых препаратов на морфометрические, фенологические и биохимические характеристики растений перца сортов Ермак и Золушка. Бактерии Bacillus subtilis №2 достоверно увеличивали урожайность, количество плодов на одном растении у обоих сортов и содержание аскорбиновой кислоты и углеводов в плодах. При этом средняя масса одного плода у перца Ермак не изменилась по сравнению с контролем. ГП Стимулайф увеличивал среднюю массу 1 плода у обоих сортов, за счет чего увеличивалась урожайность. Совместная обработка растений ГП Стимулайф и бактериями Bacillus subtilis №2 привела к интенсификации продукционного процесса растений, по сравнению с вариантами опыта, в которых применялся только ГП Стимулайф. Урожайность перца сладкого сортов Ермак и Золушка увеличилась на 10-45%, сократились сроки созревания плодов на 10-14 суток, содержание аскорбиновой кислоты выросло на 25%, сахаров –до 26%. Обоснована целесообразность совместного применения ГП Стимулайф и бактерий Bacillus subtilis №2 при выращивании перца сладкого в технологиях интенсивной светокультуры
