2. One-half pruning On the basis of single-stem pruning, retain one lateral branch under the first inflorescence of the main stem and pluck one or two fruit and then pick up the heart. This method can increase early yield.
3. Double stems to keep the main stem, leaving the first inflorescence of the next inflorescence of axillary branches, allowing it to grow to form a double rod, the remaining lateral branches were all removed, this method should be appropriate to relax the row spacing, or in the lack of fertility, insufficient number of acres This method can be used when there are missing ponds.
