根据盆友的要求，将山松逼芽过程归纳如下：   1.山松下山求活。   2.成活后，给以充足水肥，养健壮枝条，这是成功逼芽的前提。   3.逼芽时间，在两广地区从公历4月到10月都可以操作，其他地方根据本地的具体情况灵活运用。逼芽的时间选择有一点要注意：选择在雨季逼芽，所出的芽一般比较长（如图1），反之，选择在旱季逼芽，长出的芽比较短。所以，如果你的松树是养桩逼芽回缩阶段，无论是雨季或者旱季都无所谓，因为这时期的目的就是回缩阳雕刻 手套生产设备 果树反光膜 北京纯水设备 保定网站制作 枝条；要是你的松树到了成型阶段，要想得到接近五针松般的短针，除了反复逼芽外，关键就是要选在旱季剪枝逼芽了。   为什么不在冬季和春季进行逼芽呢？这是为了增强树势。因为山松冬季休眠，保留针叶有利于积蓄营养过冬；春季万物复苏，经过秋冬的营养积累，这时候所发的松芽十分健壮，让其充分生长能大大的增强树势，为逼芽成功做好充分的准备。   4.具体做法是：重剪去一半左右的枝叶。一般一年逼一次，如果第一次逼芽后，新长出的芽又长得很旺盛，可以再逼一次，但要注意不能连续都每年逼两次芽，否则树势会减弱。   5.加强肥水管理，把逼芽后的松桩养护健壮，来年就可以重复操作，这样就可以不断回缩了。（注意：没有养健壮千万不要急于逼芽，否则树势会减弱，甚至死亡
According to the requirements of the potter, the process of Pinus sylvestris forcing buds can be summarized as follows: 1. Pinus sylvestris descending the mountain to survive. After survival, providing sufficient water and fertilizer to nourish and strengthen branches is a prerequisite for successful sprouting. 3. The forced sprouting time can be operated from April to October in the Gregorian calendar in Guangdong and Guangxi regions, and can be flexibly used according to local specific situations in other regions. One thing to pay attention to when choosing the time for forcing buds is: if you choose to force the buds during the rainy season, the sprouts will generally be longer (as shown in Figure 1). Conversely, if you choose to force the buds during the dry season, the sprouts will be shorter. So, if your pine tree is in the stage of pile cultivation and forced bud retraction, it doesn't matter whether it's the rainy or dry season, because the purpose of this period is to retract the branches; If your pine tree has reached the forming stage and wants to get short needles that are close to five needle pine, in addition to repeatedly forcing buds, the key is to choose to prune and force buds in the dry season. Why not perform sprouting in winter and spring? This is to enhance the tree's strength. Because mountain pine hibernates in winter, retaining its needles is beneficial for accumulating nutrients for the winter; In spring, everything recovers, and after the accumulation of nutrients in autumn and winter, the pine sprouts produced are very robust. Allowing them to fully grow can greatly enhance the tree's vigor and prepare for successful sprouting. 4. The specific method is to cut off about half of the branches and leaves again. Usually once a year, if the new sprouts grow vigorously after the first sprouting, you can force them again, but be careful not to force the sprouts twice a year consecutively, otherwise the tree will weaken. 5. Strengthen fertilizer and water management, maintain and strengthen the loose piles after sprouting, and repeat the operation next year, so that they can continuously shrink. (Note: Do not rush to sprout if you are not strong enough, otherwise the tree will weaken and even die.)
