Yihuanhong flowering cycle control technology natural flowering extension strategy Under natural conditions, flowering is usually concentrated from June to October. By raising seedlings in the greenhouse in early spring (sowing from February to March) and combining with plastic film warming, the beginning of flowering can be advanced to mid-May. In late autumn, a sunshade net with a light transmittance of 70% is used to extend the light, which can extend the final flowering period to late November. As a typical short-day plant, precise photoperiod control method can induce flower bud differentiation by giving 8-10 hours of light per day (combined with black shading). Professional nurseries often adopt the "17 dark box treatment method": completely shaded from 17:00 every day to 8:00 the next day, and then normal maintenance can be carried out after 17 days of continuous treatment, which can achieve annual flowering. The matrix ratio and nutritional management of efficient maintenance and management systems recommends using a mixed matrix of peat: perlite: humus soil =3:1:1, and the pH value is controlled at 6.0-6.5. During the growth period, balanced fertilizer with N-P-K of 20-20 -20 and high-phosphate fertilizer with 10-30-20 were applied alternately every 10 days, and 0.2% potassium dihydrogen phosphate foliar fertilizer was added during the flower bud period. Integrated pest and disease control focuses on controlling red spiders (spraying biphenhydrazate every half month) and gray mold (maintaining air circulation + preventing pyrimethil). Yellow plates are used to trap and trap aphids and combined with matrine biological agents to achieve green prevention and control.
From cultural symbols to cultivation technology, a string of red perfectly interprets the dual value of ornamental plants. Mastering its photoperiodic characteristics and nutritional requirements, and cooperating with scientific pest and insect management, you can make this "red lips of love" bloom all year round.
