| Abstract | The work presents the results of an experimental study aimed at optimizing the process of growing varietal tulips in closed soil. A study conducted in a greenhouse complex revealed that the key factors for obtaining a high-quality cut of flowers are the choice of variety, the quality of planting material, and strict temperature control. Various methods were used, including observations, plant measurements, statistical analysis, and visual assessment. Three technologies for forcing tulips were studied: traditional and two Dutch ones – 5-degree and 9-degree. The experiment was conducted on 5,000 bulbs, including such varieties as Mosni, Go Max, Strong Gold, Strong Love, and White Flag. It was established that for successful forcing, it is necessary to use “extra” class bulbs weighing at least 25 g. The study confirmed that temperature is a decisive factor affecting the duration of forcing. It has been proven that the 9-degree technology of storing tulip bulbs gives similar results to the 5-degree technology, but with some differences. For early forcing, it is not advisable to store the bulbs until the first decade of October; for late forcing, the bulbs should be stored until mid-October. If the shoots reached a length of 7-9 cm, and it was still too early to force, the temperature was reduced to 0–2 °C for 2–3 days. Thus, the 9-degree technology allows you to regulate the timing of tulip flowering, ensuring the possibility of obtaining flowers at the right time The use of traditional technology extends the growing period by an average of 4–5 days compared to Dutch technology. The comparative analysis showed that growing tulips is a highly profitable business. During early forcing, the fastest growth of flower stalks (43 days) occurs at a temperature of 18–20 °C. For late forcing, a temperature of 10–12 °C is required, which extends growth to 62 days.The results obtained indicate that for the commercial cultivation of cut tulips, it is advisable to use modern technologies that allow controlling the growth process. | ||
