Growing seedlings of tomato varieties in protected ground

Abstract

When growing tomatoes, a seedling method is used. Seedlings are grown in special cassettes, then placed in a permanent place. This is done for a more rational use of the greenhouse area. The nursery must be absolutely clean, disinfected and have good lighting. It is necessary to have the possibility of separate temperature control and ventilation. The most convenient method is to separate a part of the greenhouse with a transparent film. To maintain a constant microclimate, a double film is used. The growing time for seedlings is 9 weeks in winter, 6 weeks in spring and 5 weeks in summer. It is very important to grow healthy, strong, well-developed seedlings to a stage close to the flowering of the first brush.
