In the fast-growing period of seedlings, no less than once a month. Urea can be applied in topdressing nitrogen fertilizer, which can be divided into two methods: dry application and wet application. The application can be applied by spreading and furrow application(seed starting trays). The spreading application is to spread the fertilizer evenly on the soil between the seedlings. After the application, the soil is covered with soil once or twice. The furrow application is to ditch the rows of seedlings. At the same time, put fertilizer into the trench and cover the soil.

When furrow application, pay attention to the depth of furrowing should be in the root distribution layer, in order to facilitate the absorption of fertilizer by seedlings. If floods and rainstorms occur after a drought, they will be easily washed away by rainwater. Generally in winter, slow release is also called long release. That is, the branches are not pruned.

Therefore, after application, choose irrigation and pressure to maintain fertilizer efficiency. Pay attention to the reasonable mix of fertilizers, especially potassium and boron fertilizers(plug trays). Because potassium ions can regulate the colloidal characteristics of protoplasts, allow water to enter the cells smoothly, and strengthen the water-holding capacity of the cells, therefore, proper potassium nutrition can enhance crop water absorption capacity, enhance crop drought resistance, and improve soil water use efficiency.

This kind of can only slowly release weak branches, lower branches and so on. One of its effects is to alleviate the growth potential: it can ease growth potential for strong trees and branches; for weak branches and weak branches, it can resume growth as soon as possible under the condition of enhanced water and fertilizer, and strengthen the tree potential. The second is beneficial to flowering and fruiting: Dogwood has the characteristics of flowering and fruiting of axillary buds, and slow release of vegetative branches can promote more flowering and more fruiting.

The temperature and humidity of the cuttings, especially the seedbed, are the most critical factors to ensure the success of the cuttings. In this way, the temperature should be maintained between 25-28 ° C, the soil humidity should be maintained at about 60%, and the air humidity should be maintained at more than 95%(flat plastic tray). Therefore, the maintenance and management measures in this process must be in place, especially in the control of temperature and humidity. As long as the maintenance is properly managed, the survival of the plant can be seen in about 1 month.

Choose a purple sand pot with good permeability as the home of fragrant wood pot or bonsai. At the same time, pay attention to changing the pot. If it is a new pot, you must soak it for at least 24 hours before replacing it. After filling the pot, the soil is compacted and watered to keep the soil moist. Many flower friends will change the pot after transplanting the fragrance wood. After transplantation, it may cause fallen leaves, which is a normal reaction. You can not worry too much.

After late autumn leaves fall, cut off the current year's disease-free branches from the mother tree, and you can also use plastic pruning to cut the thick, full buds, disease-free and mechanical damage-free branches as cuttings(black plastic plant pots). The selected cuttings are cut into 40 to 50 cm sections and buried in wet sand for storage. The selection of purple-leaf plum nursery land and site preparation nursery land should choose a place with convenient drainage and irrigation and transportation.

If the indoor temperature is appropriate, cuttings can also be performed in winter. But to avoid cuttings during the rainy season, humid environments are not conducive to their survival. Cactus does not require high soil, and can use river sand with good drainage. The soil is too viscous for its rooting and respiration. If you want to grow faster and better, use nutritious soil and add appropriate perlite. Disinfect the soil before use to avoid adverse rooting. The soil layer is required to be deep, fertile and loose sandy loam soil.
