Currently, it is already late autumn, about 20 days away from the Start of Winter solar term. Shoots sprouted by sugar mandarin oranges in late autumn are of course late autumn shoots. The start of flower bud differentiation in sugar mandarin oranges generally begins at the end of October or the beginning of November. That is, before this time, the last autumn shoots of plants planned to bear fruit the following year should be able to fully mature before their flower bud differentiation period. Therefore, if late autumn shoots are currently sprouting, they should be removed. If the tree vigor is average, it is advisable to first spray 750ppm paclobutrazol once, then spray again after 20 days. If the plants are vigorous and strong, and fertilizer and water management in the earlier period was good, then girdling can be carried out at the end of October.
