(1) Pruning of the long fruit branches of the fast-growing Phyllostachys vulgaris in Binzhou: The long fruit branches that grow in various parts can be selected. The dense long fruit branches can be thinned and erected, leaving the flat and oblique ones. The long fruit branches are placed long or lightly cut, and the tops of the branches The new shoots are few and the growth is gentle. After the branches are bent in the middle and front part, the branches are easy to shoot and grow at the back. Long fruit branches are cut in the middle, and growing branches are easy to shoot near the cutting mouth, while short branches occur in the back. The long fruit branches are short, and the main branches are growing. In the seedlings, in the long fruit branches, it is not easy to set fruit after heavy short cut, especially in the early stage of fruiting. Long fruit branches are excellent fruiting branches for seedlings, which can not only produce high-quality fruits, but also renew themselves. Pay attention to keeping more such branches when pruning.
(2) Pruning of middle-fruit branches of fast-growing Phaetonia vulgaris in Binzhou: The pruning method of middle-fruit branches is basically the same as that of long-fruit branches. Unless it is used as a preliminary branch, it is generally not short-cut, and the pruning response is similar to that of long fruit branches.
(3) Pruning of short fruit branches: Short fruit branches can leave 3 groups of flower buds short cut, but the cut must be leaf buds. If there are no lateral leaf buds on the short fruit branches, they cannot be short cut. In short fruit branches, more branches can germinate and disperse nutrients, and the growth of new shoots is not strong, especially the lower buds that are far from the cutting mouth, the germinated branches are shorter, because the short branches stop growing early and accumulate nutrients More, enhance the growth potential of mother branches. The short fruit branches are left with 1 to 2 leaf buds at the base and re-cut as preliminary branches.
(4) Pruning of bouquet-like fruiting branches: only thin out dense branches, not short cut.
(5) Pruning of extra-long fruiting branches: This kind of branches often grows vigorously and consumes很多营养,and the fruit setting is not firm. Sometimes although the fruit can be set, the fruit is small and inferior, so the fruit is generally not used. This branch mostly grows in the inner chamber or near the top of the crown. The lower part of the branch is mostly leaf buds, and only the upper part has a few flower buds. However, good fruiting branches can be formed after modification. The transformation method is to cut the topping in summer again in winter. Such branches can also be transformed into branch groups or used for renewal.
The seedlings of the fast-growing Phyllostachys vulgaris factory in Binzhou mainly produce long and medium-fruited branches, and the remaining fruiting branches should be sparse. Generally, after pruning, the branches of the fruiting branches should be kept above 20 cm, and each branch of the sapling stage bears long branches on the same side. Should keep about 40 cm.
