2. Bud wiping: timely wipe off the buds below the plastic belt, as well as the upright buds on the back of the main branches and the competing branches on the extended branches.
3. Picking: When the extension branch of the main branch is 50-60cm long, picking the core promotes the secondary branch and cultivates the main branch. Other parts grow vigorously, and the new shoots vertically overlapping with the main branches are 20cm long, which promotes the secondary branches.
4. Branch pulling: Due to the strong uprightness of papaya branches, branches should be pulled on the main branches and the first and second side branches to increase the opening angle of the main branches and side branches at all levels. At the same time, at the end of August and the beginning of September, the branches that are not reserved as main branches will be leveled and reserved as auxiliary branches.
5. Winter pruning: from February 6, 2008 to March of the following year. The methods include short cutting, thinning, retraction and slow release.
6. Tree shape: it is mainly a natural happy shape. That is, the whole tree has 30 primary main branches and 6-8 secondary main branches, each main branch has 2 lateral branches, and each lateral branch is divided into fruiting branches and fruiting branch groups. The height of the tree is about 2.5m, and the crown width is about1m.
7. The stem is fixed at a height of 80cm, and 34 new shoots growing between plastic belts are selected as primary main branches (the rest are erased) and grow outward in different directions, and the branch spacing between primary main branches is10-20 cm; 2-3 lateral branches growing to both sides are selected as secondary main branches between 30-50 cm on the primary main branch, and the branch length is 40.50 cm; ; Selecting the culture fruiting branch and fruiting branch group on the secondary main branch, wherein the branch length is l0-20cm.
