How can the trunk of Jiulixiang be long and thick?
As an aromatic plant that is deeply loved by horticulture enthusiasts, the thickness of the trunk of Jiuxiang directly affects the overall ornamental value. To achieve the goal of increasing trunk thickness, systematic maintenance is needed from four dimensions: light regulation, temperature management, nutrient supply, and morphological pruning. The specific implementation methods of each link will be analyzed in detail below. Light management: Murraya, the photosynthesis energy source, is a strongly positive plant and needs to ensure more than 6 hours of direct light every day. It should be placed in a full sunshine environment in spring and autumn, and 30% sunshade net should be used for protection in summer. In winter, you can rotate the flowerpot to allow all sides to receive light evenly. Combined with LED plant fill light, the photosynthetic efficiency can be increased by 40%, effectively promoting the accumulation of dry matter. Environmental regulation: Temperature, humidity, balance temperature and precise control of the optimal growth temperature band is 18-28℃, and controlling the temperature difference between day and night at 5-8℃ can stimulate cambium activity. When the temperature is>35℃, the atomization cooling system is started, and when the temperature is <10℃, a double-layer insulation shed is used for protection. The monthly measured ground temperature needs to be stable at 20±2℃. The humidity gradient manages the air humidity to be maintained at 60-75%, which is humidified 3 times a day through an automatic spray system. In the rainy season, it is necessary to build a rainproof canopy to avoid stagnant water and rotten roots, and the humidity of the basin soil should be maintained in the principle of "seeing wet when it is dry". Nutrition fortification: Scientific fertilization plan During the growth period (March to September), implement the "three-element cyclic fertilization method": 1. Germination period: High nitrogen fertilizer (N-P-K=20-10-10) Apply 500 times liquid fertilizer every 15 days 2. Expansion period: Balanced fertilizer (15-15-15) combined with rotten sheep manure applied around the circle 3. Lignization period: High potassium fertilizer (10-10-30) is sprayed on the leaves and applied with slow-release fertilizers such as bone meal before stopping fertilization in winter to ensure continuous supply of nutrients. Shaping pruning: Growth point control adopts the "three-level pruning method" to optimize nutrient distribution: ·Spring heavy pruning: Remove top advantage and retain 3-5 main branches·Summer pruning: cut off inner bore branches and cross branches by 30%·Autumn intensive pruning: Retain 2/3 of the new shoots, promote the thickening of branches and tie aluminum wire, which can increase the diameter of the trunk base by 1.2-1.8cm annually.
Through the synergistic effect of the above-mentioned four-dimensional maintenance system, combined with regular diameter measurements (it is recommended to use vernier calipers to record every month), significant trunk thickness can usually be achieved in 18-24 months. The key is to grasp the maintenance priorities of each growth stage and establish a complete maintenance log so that Jiuxiang flowers can show a vigorous and powerful trunk shape.
