In order to obtain robust and good new plants, the selection of fast-growing Phyllostachys vulgaris cuttings in Binzhou is the key. Be sure to choose fast-growing Phyllostachys vulgaris cuttings with strong growth, rich variety characteristics, and no pests and diseases. Binzhou fast-growing fatong cuttings must be carefully processed to ensure a high survival rate. Fast-growing Phyllostachys vulgaris cuttings are divided into dormant period and growth period due to different periods. The former is hard-growing Phyllanthus vulgaris cuttings, and the latter is soft-twig fast-growing Phyllans chinensis cuttings.
Selection and Treatment of Fast-growing Fatong Cuttings in Binzhou
(1) Selection and cutting of cuttings of fast-growing deadwood with hard branches.
①The cutting time of Binzhou fast-growing fatong cuttings. The nutrient stored in the cuttings of the fast-growing Phyllostachys vulgaris is the main energy and material source for the rooting and branching of the hardwood cuttings. The amount of nutrients stored is different when the cutting time is different. In general, deciduous tree species store the most nutrient substances in the branches after falling leaves in autumn to before germination in the following spring. In this period, the sap flows slowly and the growth stops completely. It is the best period to cut the fast-growing Phaetonia cuttings.
②Binzhou fast-growing fatong cuttings selection. According to the principle of survival of cuttings, one or two-year-old branches or sprout branches that are well-developed, robust, free from diseases and insect pests, fully lignified, and rich in nutrients should be selected from the excellent young mother trees.
Selection and Treatment of Fast-growing Fatong Cuttings
③The cutting of Binzhou fast-growing Fatong cuttings. Generally, the cuttings of the fast-growing Phyllostachys pubescens are 15-20cm long, which ensures that there are 2 to 3 well-developed buds on the cuttings. The single-bud fast-growing Phyllostachys vulgaris cuttings are 3～5cm long. When cutting, the upper incision is about 1cm away from the apical bud, and the position of the lower incision varies according to the plant species. Generally, there are many parenchyma cells near the stem nodes, fast cell division, rich nutrition, easy to form callus and rooting, so fast-growing Phyllanthus The cut under the cutting should be close to the stem node. There are several cutting methods such as flat cut, oblique cut, double-sided cut, crimp cut, and hammer cut. Generally, the rooting of the flat incision is evenly distributed in a circular shape, which is convenient for mechanized cutting. For the tree species with skin rooting and fast rooting, flat incision should be used; the contact area between the oblique incision and the cutting matrix is large, which can form a larger area of callus , It is good for absorbing water and nutrients and increasing the survival rate, but the roots mostly grow at one end of the oblique mouth, which is easy to form partial roots, and at the same time, it is more labor-intensive to cut ears; the contact area between double-sided cutting and cutting substrate is larger, and it is difficult to root There are many applications on the plants; rip-shaped and hammer-shaped cuts are generally 2 to 3 years old at the lower end of the fast-growing Phyllostachys vulgaris cuttings, and are often used for cuttings of coniferous species.
