2. After survival, give enough water and fertilizer and raise strong branches, which is the premise of successful germination.
3. The germination time can be operated from April to 10 in Guangdong and Guangxi Gregorian calendar, and can be used flexibly in other places according to local conditions. There is one thing to pay attention to when accelerating germination: when accelerating germination in rainy season, the buds are generally longer (as shown in figure 1), while when accelerating germination in dry season, the buds are shorter (as shown in figure 3' and figure 4). Therefore, if your pine tree is in the stage of piling and forced bud shrinkage, it doesn't matter whether it is rainy season or dry season, because the purpose of this period is to shrink branches; If your pine tree is in the forming stage, in order to get short needles close to the five-needle pine, in addition to repeated germination, the key is to prune and accelerate germination in the dry season.
Why not force buds in winter and spring? This is to enhance the tree potential. Because Pinus taiwanensis is dormant in winter, leaving needles is beneficial to preserve nutrients for the winter; Everything recovers in spring, and after nutrient accumulation in autumn and winter, the pine buds produced at this time are very vigorous, which can greatly enhance the tree potential and make full preparations for the success of germination.
4. The specific method is to cut off about half of the branches and leaves (as shown in Figure 2). It is generally mandatory once a year. If the new buds grow vigorously after the first germination, they can be germinated again, but be careful not to germinate twice a year, otherwise the tree will become weak.
5. Strengthen the management of fertilizer and water, keep loose piles after forced germination, and repeat them next year to make them shrink continuously. (Note: Don't rush to sprout unless you are healthy, otherwise the tree will weaken and even die. )
