How to breed three-pronged arrow
As a uniquely shaped cactus plant, Trigonium trigonum is favored by meaty lovers due to its tall and straight stems and easy-to-maintain characteristics. Many novices often encounter problems such as slow root development and plant wilting during the maintenance process, which is often closely related to improper cultivation methods. Mastering the correct cultivation techniques can keep the Triangular Arrow full of vitality from cuttage to maturity. 1. Regulation of the growth environment of Trigonium trigonum 1. Substrate formulation and basin selection The ideal substrate needs to meet the balance of air permeability and water retention: murky leaf soil provides organic nutrients, and rough river sand ensures smooth drainage. After mixing at a ratio of 4:6, 5% decomposed sheep manure is added to form a nutrient substrate. It is recommended to use red pottery pots or plain burning pots with drainage holes, and lay 3cm broken tiles on the bottom layer to form a drainage layer. 2. Coordinated management of light and temperature maintains a full sunshine environment in spring and autumn. In summer, 50% of the sun needs to be shaded from 10:00 to 15:00, and in winter, direct light is maintained for 4 hours per day. Attention should be paid to temperature control: 18-32℃ is the best during the growth period, and the overwintering temperature should not be lower than 12℃. The temperature can be maintained through double glass windows or plant fill light. Second, the core skills of rapid rooting 1. The scientific water supply scheme adopts the principle of "seeing dry and wet" in spring, and irrigates thoroughly when the moisture content of substrate drops to 30%. In summer, root water supply is carried out every morning or after sunset, combined with foliar spray to maintain air humidity above 60%. In winter, a small amount of water can be replenished along the basin wall every 20 days. 2. A 15-cm healthy stem section was selected for cuttage propagation, the incision was coated with charcoal powder, and then dried for 3 days. Use a cuttage substrate with perlite: vermiculite =1:1, maintain a constant temperature environment of 25 ° C, and use LED plant growth light to irradiate for 10 hours a day. Usually, new roots can germinate in 14-20 days. 3. Key points of full-cycle maintenance 1. Shape trimming timing. Shape trimming is carried out in April every year to remove aging edges and deformed side buds. Cutting tools need to be disinfected with alcohol, and carbendazim should be applied to the incision in a timely manner. Pause watering for 3 days after pruning, and resume maintenance after the wound forms a stratum corneum. 2. Disease prevention measures Regularly rotate flowerpots to ensure uniform light exposure, and spray garlic extract every month to prevent red spiders. When root rot is found, remove the pot immediately, remove the diseased tissue, soak it in potassium permanganate solution for 30 minutes, and replace it with a new substrate and replant it.
Through systematic environmental control and refined management, Trigonium trigonum can not only grow healthily, but also achieve the growth effect of cutting in the same year and flowering in the next year. The key is to grasp the three core dimensions of substrate ratio, temperature and light control, and water management, and dynamically adjust conservation strategies based on seasonal changes so that this desert plant can show its best condition in the family environment.
