Method 1: short cut

At the end of winter and the beginning of spring, according to the expected design effect, select the short section of latent bud point with moderate height on the blank pile. In the first year, it is allowed to grow freely. In the same period of the second year, most of the branches and shoots of the previous year are cut off according to the arrangement requirements of jungle and multi dry. At the same time, the dead branches and leaves are cut off, leaving only one or two branches at the bottom, and the new buds will germinate from the branch axils. Short cutting should be carried out once a year to prevent the trunk from growing high year by year, which is beneficial to the results of Nantian bamboo

Method 2: Acupuncture

When sprouting in spring, when the new bud grows to about two centimeters, pierce the bud stem with a fine needle. Needle once for each centimeter of new bud. The buds and stems become thicker gradually, and the number of acupuncture should be increased to two to four times. This can hinder the growth of new buds and promote the sprouting of branches and tops. Using this method for a long time, the new buds will germinate continuously, which can solve the problems of too few branches and too many branches, and can also shorten the length of branches, so as to control the shape of Nantian bamboo. Acupuncture can be carried out until June before the flowering of nantianzhu, and then it should be stopped. During this period, the clumps of nantianzhu seedlings should be removed in time.
